Experimental Investigation on Performance, Emission and Combustion Characteristics of A LHR Single Cylinder Diesel Engine Operating On Mahua Biodiesel and Diesel Fuel
The document experimentally investigates the performance, emissions, and combustion characteristics of a single cylinder diesel engine operating on mahua biodiesel blended with diesel fuel at different ratios. Mahua oil was converted to biodiesel via a base-catalyzed transesterification process. The engine was tested using diesel (B0), 10% blend (B10), 20% blend (B20), 30% blend (B30), and 100% biodiesel (B100). Results showed the 30% blend had brake thermal efficiency and exhaust gas temperatures close to diesel fuel. Emissions of CO and smoke increased with higher biodiesel content while NOx was lowest for the 30% blend. Cylinder pressure and

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. simarouba 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 simarouba oil cannot
be done, as its viscosity is more than the diesel fuel, and hence affects the combustion characteristics.
The simarouba 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, decrease. 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 and emission characteristics of SOME blend
with diesel in conventional engine and LHR engine
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.

In the present study, a twin cylinder 4-stroke dual fuel diesel engine is tested using diesel, K10 (10
% neat oil + 90% diesel) and K20 (20% neat oil + 80% diesel) with woody biomass producer gas. The test is
performed using the above test fuels in dual fuel mode at different gas flow rates under a constant load of 10
kW. This work demonstrates the effect of gas flow rates and neat oil blends on performance, emission and pilot
fuel savings of the test engine. It is observed that with increase in gas flow rates for all test fuels, performance
parameters like brake specific energy consumption (BSEC) and exhaust gas temperature (EGT) increases,
whereas brake thermal efficiency decreases. The emission parameters like carbon monoxide, hydrocarbon and
carbon dioxide values are increases. However, the oxide of nitrogen (NOx) and smoke emission parameters are
decreases with increase in gas flow rates. Similarly, in comparing between liquid fuels, with increase in blend
percentage, BSEC and EGT increases compared to diesel. The BTE is the reverse case of BSEC. In case of
blended fuels, all the above mentioned emission parameters shows lower values compared to diesel. The highest pilot fuel savings occurs in case of diesel, K10 and K20 are. 56%, 54% and 52% respectively at highest gas flow rates.

Abstract Over the last two decades there has been a tremendous increase in the number of automobiles and a corresponding increase in the fuel price. In this regard, alternative fuels like vegetable oils play a major role. Use of pure vegetable oil in diesel engines causes some problems due to their high viscosity compared with diesel fuel. To solve the problems due to high viscosity various techniques are used. One such technique is fuel blending. In the present work the pongamia methyl esters (B25, B50, B75, and B100); prepared by transesterification process was used as an alternative fuel in a diesel engine. Investigations were carried out for the performance and combustion characteristics of pongamia methyl esters. The results were compared with diesel fuel. For this experiment, a single cylinder, four stroke, water cooled diesel engine at a rated speed of 1500 rpm was used. Tests were carried out over the entire range of engine operation at varying load of 0,1, 2, 3, 4, 5.2 at rated speed of 1500rpm and results are compared with diesel. The thermal efficiency, bsfc, mechanical efficiency, volumetric efficiency are well comparable with diesel for diesel engine and low heat rejection engine and better performance and combustion characteristics are observed in case of LHR engine. From investigation it can be stated that up to 25% blend of pongamia biodiesel can be substituted for diesel engine without any modification and with modification we can blend up to 25% we can get better performance and combustion characteristics than normal engine.

Over the number of years, biodiesel is being produced from various feed stocks that are from vegetable oils or animal fats and it is well established that biodiesel up to 20% blending in fossil diesel does not require any engine modification for use. Due to high cost involvement and food security in current situation for using edible resources to produce biodiesel, researchers in India are shifting attention towards non edible resources such as Karanja seed oil, Mahua oil, Jatropha seed oil, Cotton seed oil, Mesua ferrea seed oil, Yellow oleander seed oil etc which are available in ample amount throughout the subcontinent. Extensive research has been performed on the application of biodiesel produced from these non edible resources as a fuel in diesel engines in place of petroleum diesel. This review paper discusses application of biodiesel produced from different non edible feed stocks for their application in engines as an alternative to fossil diesel in terms of engine and emission performance.

The demand for consumption of petroleum products increased with vehicles population.For
addressing the present problem we discussed alternate fuel. Moreover, the alternate fuel must be produced in
such a manner that it can be used directly in present engines without much engine modifications. Edible and
non-edible oils are the main source for alternate fuel. In this paper we have discussed the performance
characteristics of a diesel engine fuelled with mahua oil using additive. Due to high viscosity and low volatility
of non-edible oils their prolonged use is not advisable. These problems can be minimised by the
transesterification process which is a reaction of triglyceride and alcohol in presence of a catalyst to produce
mono alkyl ester which is known as biodiesel and glycerol .The biodiesel was blended with additive in various
proportions to prepare a number of test fuels which are tested on a diesel engine to studyvarious parameters
like carbon residue, fire point, flash point, viscosity, pour point, cloud point, cetane index etc. and compare
those with that of diesel . The result shows biodiesel with 10% additive (Dimethyl carbonate) is best suited for
diesel engine.

Engine performance tests showed that brake specific fuel consumption of MBD is higher than that of DF.
Performance Characteristics of a Diesel Engine Fuelled with Biodiesel Produce...IOSR Journals
The demand for consumption of petroleum products increased with vehicles population.For
addressing the present problem we discussed alternate fuel. Moreover, the alternate fuel must be produced in
such a manner that it can be used directly in present engines without much engine modifications. Edible and
non-edible oils are the main source for alternate fuel. In this paper we have discussed the performance
characteristics of a diesel engine fuelled with mahua oil using additive. Due to high viscosity and low volatility
of non-edible oils their prolonged use is not advisable. These problems can be minimised by the
transesterification process which is a reaction of triglyceride and alcohol in presence of a catalyst to produce
mono alkyl ester which is known as biodiesel and glycerol .The biodiesel was blended with additive in various
proportions to prepare a number of test fuels which are tested on a diesel engine to studyvarious parameters
like carbon residue, fire point, flash point, viscosity, pour point, cloud point, cetane index etc. and compare
those with that of diesel . The result shows biodiesel with 10% additive (Dimethyl carbonate) is best suited for
diesel engine.

The use of methyl esters of vegetable oil known as biodiesel are increasingly popular because of their low impact on environment, green alternate fuel and most interestingly it’s use in engines does not require major modification in the engine hardware. Use of biodiesel as sole fuel in conventional direct injection diesel engine results in combustion problems, hence it is proposed to use the biodiesel in low heat rejection (LHR) diesel engines with its significance characteristics of higher operating temperature, maximum heat release, higher brake thermal efficiency (BTE) and ability to handle the lower calorific value (CV) fuel. In this work biodiesel from Neem kernel oil was used as sole fuel in LHR direct injection (DI) diesel engine. The low heat rejection engine was developed with uniform metal matrix composites (MMC) coating of cylinder head. The experimental investigation was carried out in a single cylinder water-cooled LHR direct injection diesel engine. In this investigation, the combustion, performance and emission analysis were carried out in a diesel and biodiesel fueled LHR engine under identical operating conditions. The brake thermal efficiency (BTE) of LHR engine with biodiesel is decreased marginally than LHR engine operated with diesel. Carbon monoxide (CO) and Hydrocarbon (HC) emission levels are decreased but in contrast the Oxide of Nitrogen (NOx) emission level was increased due to the higher peak temperature. In the final analysis, it was found that, the results are quite satisfactory.

Abstract In this study, for the first time, a nanoceramic Al2O3 was used as a coating material in the low heat rejection engine concept. Experiments were conducted on single cylinder, four stroke, water cooled, and direct injection diesel engine. First, the engine was tested at different load conditions without coating. Then, combustion chamber surfaces cylinder head, cylinder liner, valves, and piston crown face were coated with nanoceramic material of Al2O3 using plasma spray method. Comparative evaluation on performance and combustion characteristics using diesel, multi-blend biodiesel and its blends was studied in the ceramic coated and uncoated engines under the same running conditions. An increase in engine power, brake thermal efficiency and a decrease in specific fuel consumption were observed in the ceramic coated engine compared to that of normal engine.

Abstract Biodiesel is a renewable and environmental friendly alternative fuel which can be used as a substitute for diesel in compression engine. Biodiesel can be prepared from vegetable oils and animal fats. But the application of biodiesel in diesel engine will decrease the engine’s efficiency and increase the specific fuel consumption. Application of ceramic coatings in engine will help to solve these problems. This paper presents the experimental results of mahua oil biodiesel blend in an Al2O3 ceramic coated compression ignition engine. The brake thermal efficiency, specific fuel consumption, carbon monoxide, unburned hydrocarbon and oxides of nitrogen emissions of both diesel and mahua oil biodiesel blend were measured before and after coating and the results are described in this paper. Keywords: Mahua oil, biodiesel, ceramic coating, low heat rejection.

A Study on Translucent Concrete Product and Its Properties by Using Optical F...IJMER
- Translucent concrete is a concrete based material with light-transferring properties,
obtained due to embedded light optical elements like Optical fibers used in concrete. Light is conducted
through the concrete from one end to the other. This results into a certain light pattern on the other
surface, depending on the fiber structure. Optical fibers transmit light so effectively that there is
virtually no loss of light conducted through the fibers. This paper deals with the modeling of such
translucent or transparent concrete blocks and panel and their usage and also the advantages it brings
in the field. The main purpose is to use sunlight as a light source to reduce the power consumption of
illumination and to use the optical fiber to sense the stress of structures and also use this concrete as an
architectural purpose of the building

Geochemistry and Genesis of Kammatturu Iron Ores of Devagiri Formation, Sandu...IJMER
The Greenstone belts of Karnataka are enriched in BIFs in Dharwar craton, where Iron
formations are confined to the basin shelf, clearly separated from the deeper-water iron formation that
accumulated at the basin margin and flanking the marine basin. Geochemical data procured in terms of
major, trace and REE are plotted in various diagrams to interpret the genesis of BIFs. Al2O3, Fe2O3 (T),
TiO2, CaO, and SiO2 abundances and ratios show a wide variation. Ni, Co, Zr, Sc, V, Rb, Sr, U, Th,
ΣREE, La, Ce and Eu anomalies and their binary relationships indicate that wherever the terrigenous
component has increased, the concentration of elements of felsic such as Zr and Hf has gone up. Elevated
concentrations of Ni, Co and Sc are contributed by chlorite and other components characteristic of basic
volcanic debris. The data suggest that these formations were generated by chemical and clastic
sedimentary processes on a shallow shelf. During transgression, chemical precipitation took place at the
sediment-water interface, whereas at the time of regression. Iron ore formed with sedimentary structures
and textures in Kammatturu area, in a setting where the water column was oxygenated.

Non linear analysis of Robot Gun Support Structure using Equivalent Dynamic A...IJMER
Robot guns are being increasingly employed in automotive manufacturing to replace
risky jobs and also to increase productivity. Using a single robot for a single operation proves to be
expensive. Hence for cost optimization, multiple guns are mounted on a single robot and multiple
operations are performed. Robot Gun structure is an efficient way in which multiple welds can be done
simultaneously. However mounting several weld guns on a single structure induces a variety of
dynamic loads, especially during movement of the robot arm as it maneuvers to reach the weld
locations. The primary idea employed in this paper, is to model those dynamic loads as equivalent G
force loads in FEA. This approach will be on the conservative side, and will be saving time and
subsequently cost efficient. The approach of the paper is towards creating a standard operating
procedure when it comes to analysis of such structures, with emphasis on deploying various technical
aspects of FEA such as Non Linear Geometry, Multipoint Constraint Contact Algorithm, Multizone
meshing .

Intrusion Detection and Forensics based on decision tree and Association rule...IJMER
This paper present an approach based on the combination of, two techniques using
decision tree and Association rule mining for Probe attack detection. This approach proves to be
better than the traditional approach of generating rules for fuzzy expert system by clustering methods.
Association rule mining for selecting the best attributes together and decision tree for identifying the
best parameters together to create the rules for fuzzy expert system. After that rules for fuzzy expert
system are generated using association rule mining and decision trees. Decision trees is generated for
dataset and to find the basic parameters for creating the membership functions of fuzzy inference
system. Membership functions are generated for the probe attack. Based on these rules we have
created the fuzzy inference system that is used as an input to neuro-fuzzy system. Fuzzy inference
system is loaded to neuro-fuzzy toolbox as an input and the final ANFIS structure is generated for
outcome of neuro-fuzzy approach. The experiments and evaluations of the proposed method were
done with NSL-KDD intrusion detection dataset. As the experimental results, the proposed approach
based on the combination of, two techniques using decision tree and Association rule mining
efficiently detected probe attacks. Experimental results shows better results for detecting intrusions as
compared to others existing methods
Natural Language Ambiguity and its Effect on Machine LearningIJMER
"Natural language processing" here refers to the use and ability of systems to process
sentences in a natural language such as English, rather than in a specialized artificial computer
language such as C++. The systems of real interest here are digital computers of the type we think of as
personal computers and mainframes. Of course humans can process natural languages, but for us the
question is whether digital computers can or ever will process natural languages. We have tried to
explore in depth and break down the types of ambiguities persistent throughout the natural languages
and provide an answer to the question “How it affects the machine translation process and thereby
machine learning as whole?” .
Today in era of software industry there is no perfect software framework available for

development process. This paper present the framework of skillful system combined with Likert scale. With
the help of Likert scale we define a rule based model and delegate some mass score to every process and
develop one tool name as MuxSet which will help the software developers to select an appropriate
development process that may enhance the probability of system success.
Material Parameter and Effect of Thermal Load on Functionally Graded CylindersIJMER
The present study investigates the creep in a thick-walled composite cylinders made
up of aluminum/aluminum alloy matrix and reinforced with silicon carbide particles. The distribution
of SiCp is assumed to be either uniform or decreasing linearly from the inner to the outer radius of
the cylinder. The creep behavior of the cylinder has been described by threshold stress based creep
law with a stress exponent of 5. The composite cylinders are subjected to internal pressure which is
applied gradually and steady state condition of stress is assumed. The creep parameters required to
be used in creep law, are extracted by conducting regression analysis on the available experimental
results. The mathematical models have been developed to describe steady state creep in the composite
cylinder by using von-Mises criterion. Regression analysis is used to obtain the creep parameters
required in the study. The basic equilibrium equation of the cylinder and other constitutive equations
have been solved to obtain creep stresses in the cylinder. The effect of varying particle size, particle
content and temperature on the stresses in the composite cylinder has been analyzed. The study
revealed that the stress distributions in the cylinder do not vary significantly for various combinations
of particle size, particle content and operating temperature except for slight variation observed for
varying particle content. Functionally Graded Materials (FGMs) emerged and led to the development
of superior heat resistant materials.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

India is one of the fastest developing countries with a stable economic growth, which multiplies the demand for transportation in many folds. Fuel consumption is directly proportionate to this demand. India depends mainly on imported fuels due to lack of fossil fuel reserves and it has a great impact on economy. India has to look for an alternative to sustain the growth rate. Bio-diesel is a promising alternative for our Diesel needs. With vast vegetation and land availability, certainly bio-diesel is a viable source of fuel for Indian conditions. Recent studies and research have made it possible to extract bio-diesel at economical costs and quantities. The blend of Bio-diesel with fossil diesel has many benefits like reduction in emissions, increase in efficiency of engine, higher Cetane rating, lower engine wear, low fuel consumption, reduction in oil consumption etc. It can be seen that the efficiency of the engine increases by the utilization of Bio-diesel. This will have a great impact on Indian economy.Diesel fuels have deep impact on the industrial economy of a country. These are used in heavy trucks, city transport buses, locomotives, electrical generators, farm equipments, underground mine equipments etc. The consumption of diesel fuels in India for the period 2007-08 was 28.30 million tons, which was 43.2% of the consumption of petroleum products. This requirement was met by importing crude petroleum as well as petroleum products. The import bill on these items was 17,838 crores. With the expected growth rate for diesel consumption more than 14% per annum, shrinking crude oil reserves and limited refining capacity, India is likely to depend more on imports of crude petroleum and petroleum products.[1]
Abstract: 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.

II. Materials And Methods
The extraction of biodiesel is carried out by base catalyzed transesterification method. 2.1 Extraction of biodiesel from crude mahua oil: To a one liter of crude mahua oil is heated up to 70oC. 300 ml of methanol & 5-7gms sodium methoxide of (catalyst) is added and the mixture is maintained at 65-700C is about 1½ hours and stirred continuously. The mixture is allowed to settle for 20-30 min until the formation of biodiesel and glycerin layers. The glycerin is removed from the bio-diesel in a separating funnel. The bio diesel produced from mahua biodiesel is ready to use. 2.2. Transesterificatio: It is most commonly used and important method to reduce the viscosity of vegetable oils. In this process triglyceride reacts with three molecules of alcohol in the presence of a catalyst producing a mixture of fatty acids, alkyl ester and glycerol. The process of removal of all the glycerol and the fatty acids from the vegetable oil in the presence of a catalyst is called esterification.
Physical and chemical properties are more improved in esterified vegetable oil because esterified vegetable oil contains more Cetane number than diesel fuel. These parameters induce good combustion characteristics in vegetable oil esters. So unburnt hydrocarbon level is decreased in the exhaust. It results in lower generation of hydrocarbon and carbon monoxide in the exhaust than diesel fuel. The vegetable oil esters contain more oxygen and lower calorific value than diesel. So, it enhances the combustion process and generates lower nitric oxide formation in the exhaust than diesel fuel 3. The Properties of Diesel and Mahua Biodiesel: The different properties of diesel fuel and mahua biodiesel are determined and shown in table.3.2 After transesterification process the fuel properties like kinematic viscosity, cv, density, flash and fire point get improved in case of biodiesel. The calorific value of mahua biodiesel is lower than that of diesel because of oxygen content. The flash and fire point temperature of biodiesel is higher than the pure diesel fuel this is beneficial by safety considerations which can be stored and transported without any risk.

Fig- 4.2 Variation of specific fuel consumption with brake power
The variation of specific fuel consumption with brake power for diesel, mahua biodiesel and their blends are shown in fig.4.2.As the power developed increases the specific fuel consumption decreases for all the tested fuels. This may be due to fuel density, viscosity and heating value of the fuels. BSFC of 30% blend closely matches with diesel oil. Minimum BSFC of 10% blend 20% blend and 100% blend are 0.33 kg/kW-h, 0.336 kg/kW-h, and 0.388 kg/kW-h against 0.28 kg/kW-h of diesel oil. The specific fuel consumption of all blends is more than that of diesel oil.

Fig- 4.3 Variation of exhaust gas temperature with brake power The variation of exhaust gas temperature with brake power for diesel, mahua biodiesel and their blends are shown in fig.4.2. The exhaust gas temperature of 30% blend has lower values compared with all other blends and is well comparable with diesel oil. The exhaust gas temperature of all blends with diesel increases with increases in operating loads. The 30% blend has higher performance than other blends due to reduction in exhaust loss.

4.3.4 Variation of carbon monoxide emission with brake power
Fig-4.14. Variation of CO emission with brake power
The variation of carbon monoxide emission with brake power for normal engine and LHR engine of diesel and mahua biodiesel are shown in fig.4.14. The carbon monoxide emission gradually increases with increase in load. The carbon monoxide emission of LHRD100, LHRM100 is lower than ND100, NM100.This is because of the availability of oxygen content which makes the combustion better.
4.3.5 Variation of hydrocarbon emission with brake power
Fig-4.15 Variation of hydrocarbon emission with brake power
The variation of hydrocarbon emission with brake power for normal engine and LHR engine of diesel and mahua biodiesel are shown in fig.4.15. The hydrocarbon emission is low in LHRD100 and LHRM100 when compared with the ND100, and NM100. The decrease in the hydrocarbon in the LHR engine may be due to the increase in after combustion temperature due to decrease in heat rejected to cooling and heat loss to atmosphere due to the MMC coating.

lower than the normal engine operations. The high operating temperature during combustion in low heat rejection engine makes the combustion process to nearly a complete combustion. At maximum load the carbon monoxide and unburned hydrocarbon emission level decreases for LHR engine with mahua biodiesel blend. The reduction in carbon monoxide and unburned hydrocarbon emission level is due to the high combustion temperature and availability of oxygen in biodiesel blend.
