Internal combustion engines have become recently in attention due the strict regulations regarding the environmental protection, emissions and to reduce the dependency of the fossil fuels. One choice is the use of methanol as it can be produce from renewable sources and blended with gasoline in any proportion. The aim of this study is to compare the effects of methanol ' gasoline blends regarding engine performance and exhaust emissions. The gasoline is fossil fuel which is limited in reserving causes varieties of study in search of alternative fuel for SI engine, where ethanol promises best alternative fuel. Five different blends M5, M10, M15, M20 and M25 were tested in a single cylinder spark ignition engine. The experimental results in engine performance show a decrease of torque and power up to 10 and in emissions characteristics a CO, CO2, HC. It can be concluded that methanol gasoline blends are viable option to be used in gasoline engines to replace partially the fossil fuel.

Experimental investigation of Methanol blends with gasoline on SI engineIJERA Editor
Automobile have become a very important part of our modern life style. And it runs on fossil fuel. But the excessive use of fossil fuels will very soon leads to the energy crises so the future of automobile based on fossil fuels has been badly affected by two major problems. That is less availability of fuel and environmental degradation. So it is very important to found some new renewable non polluting alternative fuels to ensure the proper and safe survival of internal combustion engines. In present study we evaluate the performance of two stroke single cylinder spark ignition engine with ratio of 10%, 20% and 30% of methanol and gasoline by volume. Performance parameters (brake thermal efficiency, brake specific energy consumption and brake specific fuel consumption) were determined at various loads on engine with methanol blended gasoline. The comparison was made on performance of conventional SI engine with pure gasoline operation. As a result, brake thermal efficiency and brake specific fuel consumption showed improved performance when compared with pure gasoline performances.

The present fossil fuel crisis and increasing vehicle population made us to think of alternate fuels. The abundance of the fossil fuels is expected to be exhaust in another 30-40 years. The cost of the fossil fuels is day by day increasing and also the emission from these fuels increases the air pollution. With keeping in view of all the above said points, it is made us to think of alternate fuels for all CI Engines. Among alternate fuels, the Pine oil blended with Methanol will promise for substituting the diesel. With pure vegetable oils there is combustion problems and which leads to more emissions in the exhaust. The present investigation evaluates Pine oil blended with Methanol in Diesel Engine. A Twin cylinder Diesel Engine adapted to study the Brake thermal efficiency, Brake specific energy consumption, and emissions in Low Cetane fuels. In this study, the diesel engine was tested using Diesel and Low Cetane Fuels. From this study the emissions like HC and CO has been reduced and Low Cetane Fuels are substitute to diesel fuel. To overcome the above problems we use combustion additives at the time of combustion. So here we use Pine oil blended with Methanol as alternative fuels in diesel Engine and perform various tests and evaluate its performance.

The power developed by an internal-combustion
engine depends upon the fuel used for combustion. Fuels
commonly used in internal combustion engines are derived
from crude oil, which are depleting and are important
sources of air pollution. In this study, n-butanol was used
as an additive with gasoline as fuel in spark ignition engine.
N-butanol exhibits good burning characteristics, contain
oxygen, reduces some exhaust emissions and as well, has
energy density and octane rating close to that of gasoline.
The various blend rates (4, 8, 12, 16 and 20 percent by
volume) were used in the engine performance analysis
using a TD110-115 single cylinder, four-stroke air-cooled
spark ignition engine test rig, under different loading
conditions. An SV-5Q automobile exhausts gas analyzer
was used to measure the concentration of gaseous emissions
such as unburnt hydrocarbon (UHC), carbon monoxide
(CO), and carbon dioxide (CO2
) from the engine tail pipe.
The results of engine performance showed reduction in the
exhaust temperature was observed for the blends than to
that of gasoline. It was observed that all the blends
improved the brake thermal efficiency and exhibited high
fuel consumption, lower specific energy consumption and
lower emissions than gasoline. All the blends performed
satisfactorily on spark-ignition engine without engine
modification.

The use of carbon-base fuels by diesel engines release gases such as CO, NOx, SO2, and THCs which constitute a major source of environmental pollution. These gases when released into the atmosphere result in the formation of acid rain and cause greenhouse effect. In the present study, an experiment was carried out with and without the use of HHO gas. The concentrations of the emitted gases were measured using an E8500 Plus gas analyzer. The results showed that the average concentrations of carbon monoxide (CO), total unburnt hydrocarbons (THCs), oxides of nitrogen (NOx) and sulphur dioxide (SO2) emitted from the combustion chamber of the test engine was decreased by 68.8%, 35.2%, 16.4% and 97.9% respectively when a mixture of HHO gas/petrol/air was used instead of petrol/air mixture in an internal combustion engine. However, the average concentration of oxygen (O2) gas increased by 1.7%.

In the present era, the world is in a difficult position as the prime problems, like
continuous depletion of nonrenewable energy resources at a brisk rate and
environment pollution due to emission of greenhouse gases which are
released on burning fossil fuels, are worsening day by day. Due to this, the
interest of the researchers is shifting toward the idea of alternative fuels
derived from biomasses, which are renewable in nature and eco-friendly in
contrast to the conventional fossil fuels, to reduce the dependence on exhausting nonrenewable energy sources. In the present study, agricultural residues
like cotton stalks and wheat straws are processed in a downdraft gasifier to
produce syngas through biomass gasification. The produced syngas is further
inducted in a gasifier-coupled dual-fuel compression ignition (DFCI) engine to
investigate the performance, emission, and noise characteristics of the dual
fuel engine to compare the standard diesel operation and syngas-diesel dual
fuel operation. The results during the investigation concluded that Dual Fuel
Compression Ignition (DFCI) engine works satisfactorily in dual fuel mode of
syngas-diesel. Moreover, a maximum 44.44% of reduction in diesel consumption is observed with a slight decrease in indicated power by 3.49% at the
maximum loading condition. In addition to the reduction in diesel consumption, the emission of nitrogen oxide was reduced by maximum of 76.74% in
dual fuel mode as compared to standard diesel operation.

Performance Test of Engine Fuelled With Diesel and Ethanol Blends.IJERA Editor
Environmental concerns and limited amount of petroleum fuels have caused interests in the development of alternative fuels
for internal combustion (IC)engines. As an alternative, biodegradable and renewable fuel, ethanol is receiving increasing
attention. An experimental investigation on the application of the blends of ethanol with diesel to a diesel engine was carried
out. First the solubility of ethanol and diesel was conducted with and without the additive of normal butanol (n-butanol). The
purpose of this project is to find the optimum percentage of ethanol that gives simultaneously better performance and lower
emissions. The experiments were conducted on a water-cooled single-cylinder Direct Injection (DI) diesel engine using 0%
(neat diesel fuel), 10% (E10-D), 15%(E15–D), 20% (E20–D), and 25%(E25–D) ethanol–diesel blended fuels. Experimental
tests were carried out to study the performance of the engine fuelled with the blends compared with those fuelled by diesel.
The test results show that it is feasible and applicable for the blends with n-butanol to replace pure diesel as the fuel for
diesel engine.

THE INFLUENCE OF CETANE NUMBER AND OXYGEN CONTENT IN THE PERFORMANCE AND EMIS...IAEME Publication
Waste plastic pyrolysis oil (WPPO) and ethanol are attractive renewable energy
sources, as ethanol has a high content of oxygen. However, for this particular study,
direct blending of conventional diesel, WPPO, ethanol and 2-ethyl hexyl nitrate (EHN)
was attempted. The purpose was, firstly, to improve the combustion, ignition quality,
performance and emission characteristics of the WPPO blends. Secondly, EHN has the
potential to reduce emissions of CO, CO2, UHC, NOX and PM. Thirdly, ethanol
improves viscosity and miscibility of biodiesel blends, besides increasing the oxygen
content of WPPO. Five mixing ratios were used in the following order,
50/WPPO25/E25, 60/WPPO20/E20, 70/WPPO15/E15, 80/WPPO10/E10 and
90/WPPO5/E5 for conventional diesel (CD), WPPO and ethanol and respectively.
However, for EHN the mixing ratio was determined by the total quantity of blended fuel
and put at 0.01 %. Complete miscibility was observed with no phase separation allowed
from the blended mixtures throughout the experiment. Performance and emission
characteristics of a stationary single cylinder water-cooled diesel power generator
were evaluated. The results obtained were compared carefully to ASTM standards and
discussed using tables and graph figure curves. The conclusion was that ethanol and
EHN can be used in diesel engine power generators as an alternative fuel to help
improve cetane numbers and to increase the oxygen content without or with
modification with WPPO blends. This is due to the densities 792 kg/m3
, 963 kg/m3
, 825
kg/m3 for WPPO, ethanol and EHN respectively, which are close to CD fuel at 845
kg/m3

Effect of Diesel Engine Fuelled with Biofuel Blendsijtsrd
The present work was conducted on a 1-cylinder, 4S, DI CI engine, on which neat diesel, neem biodiesel and polanga biodiesel and ethanol fuel were tested by varying the load on the engine setup at various blend ratios such as - diesel fuel 100 D100 , biodiesel neem 100 N100 , biodiesel polanga 50 blended with diesel 50 P50 , and ethanol 5 blended with diesel 95 E5 .The research carried was to compare the performance-emission characteristics of various blend samples w.r.t neat diesel fuel. The performance results show that, the BTE of N100, P50 fuel blends was less than E5 blend, as compared to neat diesel, whereas, the BSFC of D100, E5 blend had a decreasing nature than N100 and P50 blend. The CO emissions among the biofuel blends was maximum for N100 and then P50 blend but the least was for E5 blend w.r.t neat diesel. Also, the UHC emission for N100, P50 and E5 blends had a decreasing trend than neat diesel fuel. The D100 fuel had a maximum NOx emission in comparison to others and the least was by E5 blend. The CO2 emission of N100 and D100 was the highest than P50 and E5 blends during the operation. The unused O2for N100 fuel was the least than other fuel samples and the maximum was for E5 blend. The biofuel blends being used here had an effective outcome which can be utilised as an substitute for neat diesel.

The Impact of Digital Media on the Decentralization of Power and the Erosion ...ijtsrd
The impact of digital media on the distribution of power and the weakening of traditional gatekeepers has gained considerable attention in recent years. The adoption of digital technologies and the internet has resulted in declining influence and power for traditional gatekeepers such as publishing houses and news organizations. Simultaneously, digital media has facilitated the emergence of new voices and players in the media industry. Digital medias impact on power decentralization and gatekeeper erosion is visible in several ways. One significant aspect is the democratization of information, which enables anyone with an internet connection to publish and share content globally, leading to citizen journalism and bypassing traditional gatekeepers. Another aspect is the disruption of conventional media industry business models, as traditional organizations struggle to adjust to the decrease in advertising revenue and the rise of digital platforms. Alternative business models, such as subscription models and crowdfunding, have become more prevalent, leading to the emergence of new players. Overall, the impact of digital media on the distribution of power and the weakening of traditional gatekeepers has brought about significant changes in the media landscape and the way information is shared. Further research is required to fully comprehend the implications of these changes and their impact on society.

Comparative Analysis of Total Corporate Disclosure of Selected IT Companies o...ijtsrd
Disclosure is a process through which a business enterprise communicates with external parties. A corporate disclosure is communication of financial and non financial information of the activities of a business enterprise to the interested entities. Corporate disclosure is done through publishing annual reports. So corporate disclosure through annual reports plays a vital role in the life of all the companies and provides valuable information to investors. The basic objectives of corporate disclosure is to give a true and fair view of companies to the parties related either directly or indirectly like owner, government, creditors, shareholders etc. in the companies act, provisions have been made about mandatory and voluntary disclosure. The IT sector in India is rapidly growing, the trend to invest in the IT sector is rising and employment opportunities in IT sectors are also increasing. Therefore the IT sector is expected to have fair, full and adequate disclosure of all information. Unfair and incomplete disclosure may adversely affect the entire economy. A research study on disclosure practices of IT companies could play an important role in this regard. Hence, the present research study has been done to study and review comparative analysis of total corporate disclosure of selected IT companies of India and to put forward overall findings and suggestions with a view to increase disclosure score of these companies.

The Role of Mentoring and Its Influence on the Effectiveness of the Teaching ...ijtsrd
This paper reports on a study which was conducted to investigate the role of mentoring and its influence on the effectiveness of the teaching of Physics in secondary schools in the South West Region of Cameroon. The study adopted the convergent parallel mixed methods design, focusing on respondents in secondary schools in the South West Region of Cameroon. Both quantitative and qualitative data were collected, analysed separately, and the results were compared to see if the findings confirm or disconfirm each other. The quantitative analysis found that majority of the respondents 72 of Physics teachers affirmed that they had more experienced colleagues as mentors to help build their confidence, improve their teaching, and help them improve their effectiveness and efficiency in guiding learners’ achievements. Only 28 of the respondents disagreed with these statements. With majority respondents 72 agreeing with the statements, it implies that in most secondary schools, experienced Physics teachers act as mentors to build teachers’ confidence in teaching and improving students’ learning. The interview qualitative data analysis summarized how secondary school Principals use meetings with mentors and mentees to promote mentorship in the school milieu. This has helped strengthen teachers’ classroom practices in secondary schools in the South West Region of Cameroon. With the results confirming each other, the study recommends that mentoring should focus on helping teachers employ social interactions and instructional practices feedback and clarity in teaching that have direct measurable impact on students’ learning achievements.

This study primarily focuses on the design of a high side buck converter using an Arduino microcontroller. The converter is specifically intended for use in DC DC applications, particularly in standalone solar PV systems where the PV output voltage exceeds the load or battery voltage. To evaluate the performance of the converter, simulation experiments are conducted using Proteus Software. These simulations provide insights into the input and output voltages, currents, powers, and efficiency under different state of charge SoC conditions of a 12V,70Ah rechargeable lead acid battery. Additionally, the hardware design of the converter is implemented, and practical data is collected through operation, monitoring, and recording. By comparing the simulation results with the practical results, the efficiency and performance of the designed converter are assessed. The findings indicate that while the buck converter is suitable for practical use in standalone PV systems, its efficiency is compromised due to a lower output current.

Sustainable Energy by Paul A. Adekunte | Matthew N. O. Sadiku | Janet O. Sadikuijtsrd
Energy becomes sustainable if it meets the needs of the present without compromising the ability of future generations to meet their own needs. Some of the definitions of sustainable energy include the considerations of environmental aspects such as greenhouse gas emissions, social, and economic aspects such as energy poverty. Generally far more sustainable than fossil fuel are renewable energy sources such as wind, hydroelectric power, solar, and geothermal energy sources. Worthy of note is that some renewable energy projects, like the clearing of forests to produce biofuels, can cause severe environmental damage. The sustainability of nuclear power which is a low carbon source is highly debated because of concerns about radioactive waste, nuclear proliferation, and accidents. The switching from coal to natural gas has environmental benefits, including a lower climate impact, but could lead to delay in switching to more sustainable options. “Carbon capture and storage” can be built into power plants to remove the carbon dioxide CO2 emissions, but this technology is expensive and has rarely been implemented. Leading non renewable energy sources around the world is fossil fuels, coal, petroleum, and natural gas. Nuclear energy is usually considered another non renewable energy source, although nuclear energy itself is a renewable energy source, but the material used in nuclear power plants is not. The paper addresses the issue of sustainable energy, its attendant benefits to the future generation, and humanity in general. Paul A. Adekunte | Matthew N. O. Sadiku | Janet O.

Concepts for Sudan Survey Act Implementations Executive Regulations and Stand...ijtsrd
This paper aims to outline the executive regulations, survey standards, and specifications required for the implementation of the Sudan Survey Act, and for regulating and organizing all surveying work activities in Sudan. The act has been discussed for more than 5 years. The Land Survey Act was initiated by the Sudan Survey Authority and all official legislations were headed by the Sudan Ministry of Justice till it was issued in 2022. The paper presents conceptual guidelines to be used for the Survey Act implementation and to regulate the survey work practice, standardizing the field surveys, processing, quality control, procedures, and the processes related to survey work carried out by the stakeholders and relevant authorities in Sudan. The conceptual guidelines are meant to improve the quality and harmonization of geospatial data and to aid decision making processes as well as geospatial information systems. The established comprehensive executive regulations will govern and regulate the implementation of the Sudan Survey Geomatics Act in all surveying and mapping practices undertaken by the Sudan Survey Authority SSA and state local survey departments for public or private sector organizations. The targeted standards and specifications include the reference frame, projection, coordinate systems, and the guidelines and specifications that must be followed in the field of survey work, processes, and mapping products. In the last few decades, there has been a growing awareness of the importance of geomatics activities and measurements on the Earths surface in space and time, together with observing and mapping the changes. In such cases, data must be captured promptly, standardized, and obtained with more accuracy and specified in much detail. The paper will also highlight the current situation in Sudan, the degree to which survey standards are used, the problems encountered, and the errors that arise from not using the standards and survey specifications.

Towards the Implementation of the Sudan Interpolated Geoid Model Khartoum Sta...ijtsrd
The discussions between ellipsoid and geoid have invoked many researchers during the recent decades, especially during the GNSS technology era, which had witnessed a great deal of development but still geoid undulation requires more investigations. To figure out a solution for Sudans local geoid, this research has tried to intake the possibility of determining the geoid model by following two approaches, gravimetric and geometrical geoid model determination, by making use of GNSS leveling benchmarks at Khartoum state. The Benchmarks are well distributed in the study area, in which, the horizontal coordinates and the height above the ellipsoid have been observed by GNSS while orthometric heights were carried out using precise leveling. The Global Geopotential Model GGM represented in EGM2008 has been exploited to figure out the geoid undulation at the benchmarks in the study area. This is followed by a fitting process, that has been done to suit the geoid undulation data which has been computed using GNSS leveling data and geoid undulation inspired by the EGM2008. Two geoid surfaces were created after the fitting process to ensure that they are identical and both of them could be counted for getting the same geoid undulation with an acceptable accuracy. In this respect, statistical operation played an important role in ensuring the consistency and integrity of the model by applying cross validation techniques splitting the data into training and testing datasets for building the geoid model and testing its eligibility. The geometrical solution for geoid undulation computation has been utilized by applying straightforward equations that facilitate the calculation of the geoid undulation directly through applying statistical techniques for the GNSS leveling data of the study area to get the common equation parameters values that could be utilized to calculate geoid undulation of any position in the study area within the claimed accuracy. Both systems were checked and proved eligible to be used within the study area with acceptable accuracy which may contribute to solving the geoid undulation problem in the Khartoum area, and be further generalized to determine the geoid model over the entire country, and this could be considered in the future, for regional and continental geoid model.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

blending methanol and gasoline ina monocylindrical engine
are analysed regarding emissions levels and performance.
III. COMPARISONS OF PERFORMANCE
CHARACTERISTICS ON REVIEW PAPERS AND
REWORK FOR TEST SET-UP
Many practical experiments have been conducted to explain
the effects of methanol-gasoline blended on engine
performance. The effectofmethanol-gasoline blendedon the
engine performance is analyzed and compared the obtained
results. Some of the engine sets up and application methods
are stated in above. The following sections are the
performance characters of these methanol-gasolineblended
researches. According to these researches, this paper will
focus the effects of methanol-gasoline blendedontheengine
performances.
A. Methanol Physical Properties
Methanol is a clear, low viscosity liquid with a faintly sweet
alcohol odour at low concentrations in air. Chemically,
methanol is an aliphatic alcohol containing about 50 wt.%
oxygen with physical properties consistent with other
alcohols used as gasoline blending components (see Table
1). As is common for most alcohols blended in gasoline,
methanol is fully soluble in water and also miscible with
gasoline-type hydrocarbons (HC).

As with most gasoline and alcohol fuel blends, inhibitors or
additives are generally recommended withmethanol blends
to provide added protection against metal corrosion.
Methanol-gasoline blends have been successfully shipped
commercially in barges, pipelines, and tanker trucks similar
to those used to transport gasoline. As discussed later,
because of methanol’s affinity for water, some precautions
are necessary when shipping and storing methanol-blended
gasoline, such as mitigating water addition and using fire
extinguishing foam approved for alcohol fires. Extensive
product research, as well as years of commercial experience,
indicate that properly blended methanol in gasoline has no
adverse effect on vehicle performance. In fact, methanol-
gasoline blends have cleaner burning properties that
generally reduce CO, HC, PM and air toxics from most
gasoline engine vehicles.
B. Effect of Methanol –Gasoline Blended on Engine
Performance
LIU SHIUGHUN [17] investigated the engine with cylinder
pressure diagram. It shows that, under the same engine
speed and throttle opening, see 50% WOT (Wide Open
throttle) operation in figure 3, when the engine fuelled with
M20, the maximum pressure is higher than that of pure
gasoline operation. The IMEP (Indicated Mean Effective
Pressure) are 0.91 MPa for M20 and 0.88 MPa for pure
gasoline. Engine thermal efficiencies are 0.284 and 0.262,
respectively.

Figure 2 Engine combustion phases analyses under
30N·m operating conditions [17]
In most cases, the start of combustion is delayed due to the
methanol addition, while the rapid burning phase becomes
shorter at high speed operating conditions. Figure 2
indicates the changes of SOC (Secondary Organic Carbon)
under constant torque of 30 Nm operating conditions.
Therefore, if spark ignition time is advanced 2 or 3-degree
CA (Conditions Access), engine combustion will be
centralized near TDC (Top Dead Centre), so engine power
and thermal efficiency will be improved. The energy
performance of the engine concerning the torqueand power
are summarized in Fig. 3 and Fig. 4 The variation of engine
torque and power is dependent by the quantity of methanol
in the gasoline mixture. Increasing the fraction of methanol
results in a decrease of performance, meaning lower value
for the parameters examined previous at different speeds
and loads of the engine. S. Liu et al. [18] and Figure 3 and
Figure 6 show apparatus of experiment with Schematic
diagram and Engine Stand. [18,20]

C. Methanol-Gasoline Blended Effect on Emission
The exhaust gas analyser unit for special cases of internal combustion engines should record the values of Carbon Monoxide
(CO), Carbon Dioxide (CO2), Oxygen (O2) and Hydrocarbons (HC). The following figures, Fig.6 and Fig.8, show the variationof
pollutant emissions versus the load of the engine for different engine speeds of 3600 and 4600 rpm, starting from where the
load will be applied. As it can be seen, the values of CO decrease once the percentage of methanol is increased. The effect is
generated by the quantity of oxygen contained by the alcohol and by the carbon that is found in greater proportion in gasoline
rather than in methanol composition, [19].

Fig.7 Methanol influence on CO2 emissions, a) 3600 rpm, b) 4600 rpm [20]
Fig. 7 indicates the evolution of CO2 emissions for two different engine speeds starting from 0 to 100 % load. It can be seen an
increasing trend for the alcohol gasoline blends. At a high engine speed, the emission value has a great value do the quantityof
air and fuel that increase the rate of complete combustion. Similar results were recorded with differences up to 13% higher
CO2 emissions for methanol-gasoline blends [20].
Fig. 8 Methanol influence on HC emissions, a) 3600 rpm, b) 4600 rpm [21]
Fig. 8 depicts the evolution of HC emissions, which can rise rapidly due to incompletecombustionorheatlossesinthecylinder.
Increase of the HC emissions can be caused also by the existence of regional leanandrichmixturesinthecombustionchamber.
Experiments show a decreased value of the emissions when the gasoline is mixed with methanol, influenced by the carbon to
hydrogen fuel ratio which is lower than in the case of gasoline, [21].
D. REWORK EXPERIMENTAL SETUP AND PROCEDURE Multi-cylinder four stroke spark ignition engine was used.
Tests were carried out at wide open throttle (WOT) condition. The specifications of the engine are given in Table 2.

To get a good result for methanol-gasoline blended engine,
some steps needed to satisfy step by step. The engine was
started and allowed to warm up for a period of 10-15min.
Before using the engine to a new fuel blend,itwas allowedto
sum for sufficient time to consume the remaining fuel from
the previous experiment. It was exited the mixtures by
weighing the appropriate amount of methanol on a sale and
then added it to the gasoline. Engine test were performed at
constant engine speed. The speedcanbemeasured bydigital
tachometer. After all of the data collected, it was determined
the air-fuel ratio by using the air flow reading and the fuel
flow reading. Three runs were performed to obtain on
overage value of the experimental data for each experiment.

Tests were performed at various loads as 200 watts, 400
watts, 600 watts, 800 watts, 1000 watts and 1200 watts at
constant engine speed 1300 rpm. In this study the blends
were prepared on volume basis. Methanol was blended in
gasoline in concentration of 15% and 20% and their blends
are known as M15 and M20. Their CV Values are 8950.10
Cal/g at M 15(Methanol and 92 Grade Petrol) and 7151.89

brake thermal efficiency was estimated by standard
equations.
Brake power have 0.1159 kW (200-Watt load),0.3068 kW
(400 Watt),0.4965 kW (600 Watt),0.75 kW (800 Watt) and
1.026 kW (1000 Watt) respectively at constantenginespeed

,4.8%,7.2%,10.6% and 14.03% respectively.
IV. CONCLUSION
From this other researcher, it can be showed that low
fraction methanol-gasoline blend can be used in SI engines
without any modifications. The fuel blend has slightly
lowered the engine power and torque, while increases
engine breaks thermal efficiency.Methanol gasolineblended
fuel may lower HC and CO emissions. The resultsalsoshowa
decrease of the CO and CO2 emissions and an equivalent
variation of the HC emissions, which proves that the
combination of these two could offer a viable solution.
Finally, it can be reviewed for this paper to show engine
power and torque when using gasoline, a little increase than
when using methanol gasoline blends nevertheless other
benefits for emissions (such as CO2, CO and HC) when using
methanol gasoline blends is higher than when using only
gasoline. So, it can get better human’s life and health and
reduce global warming case when using methanol-gasoline
blends.
FUTURE WORK
There are many results demanding farther research and
development work are as follows.
It has been carried out studies on SI engine aiming to
reduce mainly emissionsand final testing withmethanol
gasoline blends to satisfy nearly theoretical and
experiments results in SI Engine
