Performance Analysis of Diesel engine using metal coatings on piston head

Diesel engines are widely used in transport sector and other areas. Improvement of performance and reduction of smoke density (Emissions) is the important aspect in the combustion ignition engine. The performance of the engine can be increased by the following factors: (a) Reducing the heat energy going out as waste through exhaust gas, (b) Increasing compression ratio (c) Using proper injection timing, (d) Using catalyst coating on the piston top in the combustion chamber. In this project coating on the piston top is selected. This method improves the performance of engines, also reduces the smoke density (Emissions). Many researchers are studying the performance analysis aspects and are coming with useful results. Hence in this experiment an attempt has been made to study the performance of Diesel engine by using the metal catalyst coatings on piston top of Internal Combustion Engine. To overcome the problems of low efficiency and high smoke density of diesel engine, it was decided to coat the catalyst on the top surface of the piston and to speed up the combustion process, supplying more quantity of oxygen at the time combustion. This process of coating the piston will give the better result.
