The methyl and ethyl esters of vegetable oils, known as biodiesel are becoming increasingly popular because of their low environmental impact and potential as a green alternative fuel for diesel engine. In the present work, methyl and ethyl esters of nerium oil were prepared by transesterification using both methanol and ethanol. However, viscosity of ethyl esters of nerium oil (EEON) was slightly higher than that of methyl esters of nerium oil (MEON). A single cylinder stationary kirloskar engine is used to compare the Performance and Emission and Combustion characteristics between pure diesel and nerium blends. The nerium oil blends are in percentage of 20%, 40%, 60%, 80%, and 100% of nerium oil to 80%, 60%, 40%, 20% and 0% of diesel. Results show that methyl esters of nerium oil (MEON) produced slightly higher efficiency than ethyl esters of nerium oil (EEON). Exhaust emissions and Combustion characteristics of methyl esters of nerium oil (MEON) were also higher than ethyl esters of nerium oil (EEON). Hence methyl and ethyl esters of nerium blend can be used in existing diesel engines without compromising the engine performance.Keywords

This study investigates the use of methyl esters of Algae oil and its blends as fuel for a CI engine. Algae oil is not ideally suited as an engine fuel as such because of its high viscosity and low volatility. A process of transesterification has to be done to improve the properties of algae oil to make it comparable with diesel. Properties of the methyl ester of algae oil was evaluated and compared with diesel. The esterified fuel was used to evaluate the performance combustion and emission characteristics of a single cylinder, direct injection diesel engine. The data thus generated were compared with the data obtained using diesel. The engine exhibited a very good performance without any problem of combustion. It is suggested that, the methyl ester of Algae oil and its blends can be used as an alternate fuel for diesel engine.Keywords

In this direction, an attempt has been made to investigate the performance, combustion and emission characteristics of esterifies Nerium oil mixed with ethanol. The fuels considered are 5%, 10%, 15%, 20% of ethanol (biodiesel) blended with 95%, 90%, 85%, 80% esterifies nerium oil oil. The results derived from the test shows that Nerium oil mixed with ethanol has a kin performance characteristics as that of diesel and better emission characteristics. Hence bio-fuels of Nerium oil mixed with ethanol can replace the diesel without compromise in engine performance.
At present neither Nerium oil nor bio-diesel of Nerium oil is available in the market. Hence for our work, well grown Nerium seeds are collected from different parts of Tamil Nadu (India). Then after proper filtration, esters of Nerium oil are prepared using the bio-diesel plant available in the department.

The major fuel used for commercial vehicles in India is the diesel fuel. This is non-renewable fuel is also depleting oil resource. Diesel is well suit for the commercial transportation purpose compare to the other fuel including gasoline. Thus the various blends are used, as it is same as that of diesel properties.In this direction, an attempt has been made to investigate the performance, combustion and emission characteristics of esterifies Nerium oil mixed with ethanol.

Objectives: To study the effect of coating (with or without) in the chill plate material on the chilled cast iron engine tappet. Methods/Statistical Analysis: The impact of Coating material and chill plate over chilled depth has been examined. Experimental work was contacted with coating and without coating material. The Design Of Experiment (DOE) will be performed and taking into DOE account; the trail will be reached. The casting of tappet with differing the measure of coating material influences the chilled depth that has been checked taking into microstructure study account. Finding: Coating thickness affects the chilled and mottled depth growth. Our aim is to increase the chill depth and decrease or to avoid the molted zone. As per excremental trials, we observed that Coating thickness increases the chill depth and as well as molted depth also. We have to use the coating thickness very carefully to manage the chill and mottled depth. Combination of with coating thickness (0.3 mm) and Gray cast iron is giving good results for the chilled depth. Application/Improvement: This mushroom type tappet is used in automobile industry as especially Heavy vehicles like trucks, tractors and etc. Coating on shell mold will give us the more chill depth on the tappet head which will improve the engine tappet life and diminishing tappet casting outer surface roughness by 2-4 times.Keywords

Alcohol is a good alternate fuel by comparing its performance, availability and renewability against fossil fuels. Ethanol is widely used in IC engines by blending small amount with petroleum fuels, but it is not solely used because its high boiling point and self-ignition temperature makes it difficult to burn in engines because, auto ignition also is not possible because of its high octane number and engine needs spark ignition. In order to overcome this problem we need a spark ignited engine with high compression ratio. So a high compression ratio engine is modified into spark ignited engine. A carburetor with 2mm main jet to supply excess fuel into engine is used in order to compensate its low calorific value. The engine used in this experiment was a single-cylinder direct injection diesel engine with a cylinder bore of 95mm, a stroke of 110 mm and a compression ratio of 13:1. The rated power was 5.3 kW at 1500 rpm. The engine has been tested at different loads for Ethanol against spark timings when piston is at TDC, 5 degree before TDC, 10 degree before TDC, 15 degree before TDC respectively. The optimum spark timing is found among the experimental basis for Ethanol.Keywords

This project aims at evaluating the distribution of back pressure along the length of the effect of back pressure on fuel consumption of a carbureted SI engine. A baffle arrangement installed in the line from the manifold is used to alter the back pressure. The effect of baffle assembly (with four baffles of various angles) fitted at the silencer and the back pressure on the fuel consumption have been determined. Baffle assembly is helpful for the back pressure suppression and it causes change in fuel consumption. The models are analyzed using computational fluid dynamics software fluent for predicting the pressure drop across the muffler. The values of transmission loss and pressure drop is found for all the models and compared. The optimized design is selected from the model having more transmission loss and low pressure drop. The optimized model will be fabricated and tested by fitting in an internal combustion engine to evaluate the engine performance and pressure drop produced by the muffler.Full Text

The objective of this endeavor is to investigate the influence of graphite particles addition to the Al/SiC composites manufactured by stir casting method. Al/SiC/Gr hybrid metal matrix composites are preferred replacement for single reinforced composites by virtue of strengthened mechanical and tribological properties. A layered SiC/Gr composite material is required in gas turbine combustor can. Al/SiC/Gr composites are required in bearings, and pistons due to selflubrication, low wear rate and less friction. The inclusion of both strong reinforcement like SiC and smooth reinforcement like graphite enhances hardness and wear resistance of aluminium composites. The reinforcement content of graphite was varied from 2.5 to 7.5 wt % in a step of 2.5 wt. The SiC was fixed at 5 wt. % for all the three specimens, and Al6061 was used as matrix base material. The microstructure and EDAX analyses were required for three samples of hybrid metal matrix composites. Vickers hardness and porosity decreases for Al/SiC/Gr hybrid composites when percentage of graphite content increases. A review of surface modification of Al/SiC/Gr was done to find the different materials used for coating hybrid composites.Keywords
