Abstract:
Depleting petroleum reserves on the earth and increasing concerns about the environment leads to the question for fuels which are eco-friendly safer for human beings. The objective of present study was to investigate the effect of coating on cylinder head of a Diesel engine on the performance and emission characteristics of exhaust gases using Bio Diesel and High Speed Diesel (HSD) as a fuel. In this study the effect of Tin and Hard Chrome coating on the performance and emission characteristics of diesel engine was investigated using Bio Diesel and High Speed Diesel as a fuel. For this purpose the cylinder head of the test engine were coated with a Tin and Hard Chrome of 100 µ thick by the Electroplating method. For comparing the performance of the engine with coated components with the base engine, readings were taken before and after coating. To make the diesel engine to work with Bio Diesel and High Speed Diesel a modification was done. The engine’s performance was studied for both Bio Diesel and High Speed Diesel with and without Tin, Hard Chrome coating. Also the emissions values are recorded to study the engine’s behavior on emissions. Satisfactory performance was obtained with Tin and Hard Chrome coating compared with a standard diesel engine. The brake thermal efficiency was increased up to 2.08% for High Speed Diesel with Tin coating and there was a significant reduction in the specific fuel consumption. The CO emission in the engine exhaust decreases with coating. Using Bio Diesel and High Speed Diesel fuel for a LHR diesel engine causes an improvement in the performance characteristics and significant reduction in exhaust emissions.
