The document experimentally investigates the performance, emissions, and combustion characteristics of a diesel engine fueled with blends of biodiesel extracted from mahua oil. Various blends from 10-50% mahua biodiesel were tested and compared to diesel. The brake thermal efficiency was highest for B30 and the brake specific fuel consumption was lowest for B30 at full load. Carbon monoxide and unburned hydrocarbons decreased with increased biodiesel content while NOx increased. Cylinder pressure and heat release rate were comparable or higher for biodiesel blends compared to diesel. Overall, B30 performed best with reduced emissions and higher efficiency compared to other blends and diesel.
Anxiety of greenhouse gases and exigency of conventional fuels is an attractive exploration reneged to the researchers view, turn towards alternative fuels. The present work is to demonstrate on performance, combustion and emission characteristics of 20% Karanja Methyl Ester (KOME) blend (B20) and hydrogen with 5, 10, and 15 lpm (liters per Minute) of low flow rate on a dual fuel mode direct injection diesel engine operated at 1500 rpm with rated power output of 3.5 kW. The experimental test were conducted at three various injection operating pressure of 200, 220, and 240bar. The obtained data of above test were compared with base line pressure of diesel at 200 bars. Higher brake thermal efficiency, less brake specific fuel consumption, lower HC, and CO emissions with raised concentration of NOx were obtained at IOP of 240 bars for B20- hydrogen dual fuel mode. The current analysis discovered that the IOP of 240 bars for 15 lpm hydrogen flow rate with B20 dual fuel approach was optimum.

In this research work the detailed investigation on performance and combustion characteristics of four stroke single cylinder engine with karanja and rapeseed biodiesel and its blends with diesel (in proportions of 20% and 50% by volume) under various load i.e. at no load, 25%, 50% and full load was assessed. At full load KB50 (karanja biodiesel blend) has been recorded lowest rate of pressure rise. KB20 has lowest
recorded BSFC as compared to all others of biodiesel for all loading condition even than diesel. The RB20 (rapeseed biodiesel blend) recorded maximum BMEP at full load. KB20 was recorded with maximum brake thermal efficiency at full load. So on the basis of performance and combustion parameters KB20 appears to be best alternative fuel than other blends of karanja biodiesel and rapeseed
biodiesel even than diesel.
This paper describes the CFD analysis and experimental validation for a blend of Ethanol and Diesel in CI Engine. Ethanol is the alcohol found in alcoholic beverages but it also makes an effective motor fuel. Since, ethanol possess low Cetane number it fails to auto ignite. In order to overcome this Diesel is blended with Ethanol. Thus the Diesel will ignite and thus facilitate the Ethanol to start burning. In this work a CFD model was created and the combustion analysis was carried out and the results were validated with experimental data. The Ethanol and Diesel fuels were mixed in different proportions and they were injected to the combustion chamber of a normal diesel engine. A single cylinder PC based VCR Engine was operated with this Ethanol - Diesel blend in different concentrations and at various loads. The experiment was successful and it showed that the Ethanol could be mixed with Diesel and could be injected without any engine modification. The difference between CFD and the experimental results obtained was found within acceptable range.

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.

Experimental Investigation on Use of Honge(Pongamia) Biodiesel on Multi-cylin...ijsrd.com
Biodiesel is a fatty acid alkyl ester which is renewable, biodegradable and non toxic fuel which can be derived from any vegetable oil by transesterifiaction process. Biodiesel has become a key source as a substitution fuel and is making its place as a key future renewable energy source. Biodiesel derived from vegetable oils are quite promising alternative fuels for diesel engines. Use of vegetable oils in diesel engines leads to slightly inferior performance and higher smoke emissions due to their high viscosity. The performance of vegetable oils can be improved by modifying them through the Transesterification process. In the present work, the performance of single cylinder direct injection diesel engine using honge as fuel was evaluated for its performance, emission and combustion characteristics. The properties of honge thus obtained are comparable with ASTM biodiesel standards. The produced honge biodiesel was tested for their use as a substitute fuel for diesel engine. Tests have been conducted at different varying load of biodiesel, at 60% throttle. The performance parameters elucidated includes brake thermal efficiency, specific fuel consumption, torque, also emission characteristics against varying Brake Power (BP) and combustion characteristics against crank angle.
The search for alternative fuels in last few decades is intensive due to the rapid
depletion of petroleum fuels and their ever increasing costs. There is a great need to
reduce the consumption of conventional fuels in both developed and developing countries.
The consumption and demand of the petroleum based fuels is increasing every year due
to the increased industrialization and innovation in the world. The aim of the present
experimental work is to evaluate the impact of various compression ratio using blends of
diesel fuel with 20% concentration of Methyl Ester of Jatropha biodiesel blended with bio
additive and the blends of diesel fuel with 20% concentration of methyl ester of mahua
biodiesel blended with bio additive as an alternate fuel. The experiment is carried out
with three different compression ratios in DI diesel engine. Biodiesel is extracted from
Jatropha oil and mahua oil, 20% (B20) concentration with 3ml bio additive is found to
be the best blend ratio from the earlier experimental study. 3ml of biodiesel B20MEOJBA
and 3ml of B20MEOMBA is tested with compression ratio of 17.5. The purpose of the
experimental study is to obtain better efficiency, minimum specific fuel consumption, and
lower smoke and lesser emission. This is done by increasing cetane number using
combustion additives of 3ml bio additive blends with biodiesel when compared with the
baseline diesel.

In the present world it is essential to find an alternate fuel source due to the increased industrialization and depletion in natural resources. The method of obtaining biodiesel from various sources and blending them with diesel is adopted in many economically developed and developing countries around the world. This paper investigates the utilization of Pongamia Pinnata Methyl Ester (PPME) blends with diesel in CI engine. The performance and emission characteristics of pongamia with diesel with B40 could substitute in the place of pure diesel and be used as an alternate source of fuel in the near future, thus saving the natural resources for the future generation. Performance parameter like brake thermal efficiency, specific fuel consumption, mechanical efficiency, brake power is evaluated.

Diesel is a fossil fuel that is getting depleted at a fast rate. So an alternative fuel is necessary
and a need of the hour. Rice bran oil, which is cultivated in India at large scales, has a high potential
to become an alternative fuel to replace diesel fuel. Direct use of mahua oil cannot be done, as its
viscosity is more than the diesel fuel, and hence affects the combustion characteristics. The mahua oil is
esterified to reduce the viscosity and it is blended with diesel on volume basis in different proportions.
The use of thermal barrier coatings (TBCs) to increase the combustion temperature in diesel engines
has been pursued for over 20 years. Increased combustion temperature can increase the efficiency of
the engine. However, TBCs have not yet met with wide success in diesel engine applications because of
various problems associated with the thermo-mechanical properties of the coating materials. Although,
the in-cylinder temperatures that can be achieved by the application of ceramic coatings can be as high
as 850-9000C compared to current temperatures of 650-7000C. The increase in the in-cylinder
temperatures helped in better release of energy in the case of biodiesel fuels thereby reducing emissions
at, almost the same performance as the diesel fuel. Here the effort has been made to determine the
performance, emission and combustion characteristics of MOME blend with diesel in conventional
engine and LHR engine.

A comparison analysis between neat diesel (petro-diesel) and neat Hydnocarpus Pentandra (Marotti) biodiesel has been carried out on a direct injection diesel engine. The biodiesel has been produced from raw Hydnocarpus Pentandra oil by transesterification process by adding methanol and base catalyst. The optimum nozzle pressure of 250 bar and static injection timing of 20° bTDC are considered because these conditions only were found to give minimum emissions and better performance. The engine performance and emissions of diesel engine fuelled with neat diesel and neat Hydnocarpus Pentandra (Marotti) (or) Marotti Oil Methyl Ester (MOME) results are compared and presented. From the test results, it could be noted that, neat MOME gives lower emissions such as hydrocarbon and oxides of nitrogen as compared to neat diesel for all load under steady state condition of the engine.

Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Abstract: - Nowadays the crude oil is depleting at a fast rate and cannot be produced in short duration of time as
it is non-renewable source of energy,therefore it is high time to study & research over and to act towards the
sustainable use of our natural resources like petroleum products.Biodiesel is a renewable alternative fuel created
from vegetable oils, animal fats, and greases through a chemical process. The chemical process involves
reaction of natural oils with an alcohol, and then refining the mixture to create molecules which can be easily
burned in a diesel engine.In the present study,biodiesel extracted from mahua oil was taken & the evaluation of
the performance, emission and combustion characteristics of a compression ignition engine fuelled with
different blends of biodiesel extracted from mahua oil biodiesel was done. The c.i. engine was single cylinder,
four stroke, water cooled, and naturally aspirated direct injection (DI) diesel locomotive.
The performance, emission and combustion characteristics of the engine fuelled with mahua oil biodiesel and
diesel blends was investigated and compared with that of standard diesel. The experimental results confirm that
the Brake thermal efficiency(BTE), Brake specific fuel consumption(BSFC), exhaust gas temperature are the
function of biodiesel blend and load. For similar operating conditions, a particular blend gave better engine
performance and reduced emissions compared to other blends in comparison to standard diesel. The brake
thermal efficiency of mahua biodiesel blends is higher than that of diesel at all load conditions. Results showed
that biodiesel obtained from Mahua oil can be used as a great and sustainable substitute for fossil fuels.
Keywords: Biodiesel, Combustion, Performance, Emissions, Mahua Oil, Load, BSFC,BTE.
I. INTRODUCTION
As per the excessive and dependant use, it is believed that crude oil and petroleum products will
become very scarce and costly to find and produce. Although fuel economy of engines is greatly improved,
increase in the number of automobiles alone explains that there will be a great demand for fuel in the near future.
Alternative fuel technology, availability, and use must and will become more common in the coming decades.
Another reason providing motivation for the development of alternative fuels for the IC-engine is concerned
over the emission problems of gasoline engines. Combined with other air polluting systems, the large number of
automobiles is a major contributor to the air quality problem of the world. A third reason for alternative fuel
development is the fact that a huge percentage of crude oil must be imported from other countries which control
the larger oil fields.
. Biodiesel is produced from the transestrification reaction of vegetables oil or animal fats with alcohol
in presence of a catalyst. As per scientist’s recommendation, pure biodiesel can not used for conventional
engines. Therefore Engine modifications are required to use pure bio-diesel which is an expensive affair.
Henceforth, bio-diesels are generally mixed/blended with petroleum diesel at predetermined percentages to
create a proper biodiesel blend. But the performance of the engine varies with the amount of concentration of
bio-diesel used.
Engine’s Vibration,power/torque,Fuel Consumption and Emission are some of the standard parameters
which determines the quality and performance of the fuel used. Fuel price and consumption determine the
economy of using the fuel. Poor fuel performance will lead to frequent maintenance and more often replacement
of the engine. Hence, over the years,finding an optimum Blend of bio-diesel and petro-diesel which gives the
best operating characteristics has been a requirement.
II. EXPERIMENTAL WORK
For the present study a single cylinder, four stroke diesel engine, Kirloskar, Model TV1, connected to
eddy current type dynamometer for loading, smoke meter to measure smoke and five gas analyzer for exhaust
gas evaluation, is employed. It is provided with necessary instruments for combustion pressure and crank-angle
measurements. These signals are interfaced to computer through engine indicator for Pθ−PV diagrams.
Provision is also made for interfacing airflow, fuel flow, temperatures and load measurement. The setup has

III. RESULTS AND DISCUSSIONS
Figure 2 shows that the variation of brake thermal efficiency (BTE) with load for different blends. It
has been observed that the brake thermal efficiency for all test fuel is 85 increasing with the increase in applied
load. It happens due to a reduction in heat loss and increase in power developed with increase in load. Blend
B30 and diesel has been shown the BTE of 33.75% and 34.57% respectively. Hence B20 gave the little
difference in efficiency among all test fuel, which is about 0.82% less than the diesel. Initially, efficiency was
found to be increased with increased blend ratios up to B30 and after that it got a decrease as shown in figure 2.
The decrease in brake thermal efficiency for higher blends may be due to the combined effect of its lower
heating value and increase in fuel consumption. In spite of this increasing viscosity may be the other reason for
decreasing efficiency with higher blend ratio fuel, thereby, poor spray and poor atomization occurred due to
which charge was not properly burned.

Fig. 2 Variation of Brake power with BT Efficiency
The variation of brake specific fuel consumption with regard to load is given in figure 3. B30 has given
lowest brake specific fuel consumption to all other blends and diesel at full load condition. Diesel and B30 has
been read 0.25 kg/kWh and 0.25 kg/kWh of BSFC respectively, at full load which is more or less same as diesel.
For a higher percentage of biodiesel blends BSFC are found to be increased. B30 has minimal value of fuel
consumption among B10, B20, B50 and B100 at and above 100% load.
Fig. 3 Variation of Brake power with BSFC
Figure 4 shows the variation of carbon monoxide emission of blends and diesel under various loads.
The discharge of CO is found to be diminished with increasing load at the initial stage up to approximate 75%
load after that it increases for B10 up to 0.2 (%V). But for B30 decrement of 0.2 (%V) of CO at stage of 75% to
100% load. This is because of more fuel accumulates at higher load to produce more power due to which higher
temperature achieved in the fumes. This increased temperature helps in the oxidation of CO on account that its
value decreases. Blend B10, B20, B50 and B100 have been given equal amount of CO to that of diesel at full
load stage, because for B10 due to the inefficient inherited oxygen of biodiesel CO could not oxidized to CO2,
and for B50 increased viscosity and high non volatility of biodiesel caused poor spray, atomization and burning
of CO into CO2.
Variation of unburned hydrocarbon can be seen in figure 5. Significant reduction in HC emission has
been found with decreasing the blend ratio of biodiesel in fuel. Blends B10, B20, B30, B50, B100 and diesel are
given 36.5ppm, 34.8ppm, 30.2ppm, 23ppm, 23.2 and 27.4ppm of HC emission on an intermediate basis. Hence
B50 and B100 has been given lowest HC compare to all test fuels due to optimum level of oxygen and viscosity
of fuel.

Fig. 4 CO (%V) Vs BP (KW) emission
Fig. 5 Unburned HC Vs BP
Variations of NOx emission with loads for different blends are presented in figure 6. The NOx
emission is found to be increased with growth in shipment due to less heat rejection at higher load. That is the
way all test fuels shows highest value of discharge at full load condition. Blends B10, B20, B30, B50, B100 and
diesel show 549ppm, 743ppm, 608ppm, 704ppm, 669ppm and 730ppm respectively at full load condition. it can
be concluded that B20 exhibiting proper complete combustion compare to others fuels.

Fig. 6 NOx Vs BP
Percent of CO2 in exhaust is the direct indication of complete combustion of fuel in combustion
chamber. Figure 7 shows the variation of CO2 under varying load for different biodiesel blends. All test fuels
show increasing trends, CO2 emission with increase in shipment due to increase in accumulation of fuel. Blends
B10, B20, B30, B50, B100 and diesel shows 3.6%, 4%, 3.7%, 4,2%, 3.7% and 4.5% of CO2 respectively at full
load condition. Only B50 has been shown higher CO2 emission compare to diesel due to the significant issue of
higher cetane number compare to other test fuel. Other blends have been presented the lower value of CO2 than
diesel. It can also be cleared from exhaust gas temperature vs. load curves in which B50 has been shown higher
temperature than other blends.
Fig. 7 CO2 Vs BP
Figure 8 shows the variation of incylinder pressure with crank angle for blends B10, B20, B30, B50
and B100 in comparison of baseline data obtained from standard diesel. Pressure rise has been found to be
comparable with diesel for higher biodiesel blends fuel.
Moreover, low biodiesel blends such as B10 and B20 show delayed pressure rise with respect to standard diesel
at full load due to longer physical ignition delay period because of the higher boiling point range of biodiesel
compare to diesel. It can as well be visualized in figure 8 that all test fuel has shown decreases in ignition delay
with increase in shipment.

International organization of Scientific Research 29 | P a g e
Fig. 8 Incylinder pressure vs. crank angle
This was passed due to increase in gaseous state temperature at high load operation, therefore reduction
in the physical ignition delay period was held. In all cases higher biodiesel blends as B100 and B50 has been
shown higher incylinder peak pressure compare to diesel and other low biodiesel blends. Two elements are
mostly responsible for that first presence of inherited oxygen molecules in biodiesel helps in combustion and the
second is the lower viscosity of mineral diesel which ensures adequate air-fuel blending.
Figure 9 shows the heat release rate for biodiesel blends in comparison of standard diesel at different
engine operating conditions. After burning of fuel, fluctuation of heat release rate occurs. However, at B100
shows highest rate of heat release compare to diesel and other biodiesel blends, because of the higher cetane
number and higher oxygen capacity of biodiesel that improves the burning quality of fuel and helps in firing at
higher charge per units. Moreover B10, B20 and B50 have been established a corresponding rate of heat release
with diesel. This is because, in low blends the concentration of biodiesel is low, that is way fuel does not cause a
significant force on certain number, but it touches the air fuel mixture formation due to changes in viscosity and
evaporation properties of the fuel. That is way lower blends showed a less charge per unit of heat release than
B100.

IV. CONCLUSIONS
The brake thermal efficiency of mahua biodiesel blends is higher than that of diesel at all load conditions.
The brake thermal efficiency of mahua biodiesel blends is higher than that of diesel at all load conditions.
