Abstract: The energy crises and environmental pollution have promoted to use one of the concept of adiabatic engine with catalyst coated combustion chamber of internal combustion engine.[5] The concept of catalytic combustion in direct injection diesel engines has been adopted by various researchers which improve exhaust emissions due to oxidation of fuels by aid of catalyst. To achieve the present requirement of the automotive industries there is continues research to improve performance, exhaust emission and life of the internal combustion (I.C.) engine. The recent research has been focused on the reduction of diesel engine pollutions due to strict emission regulations. [6] Which directly affected to human and environments. The present investigation has been made to study mainly emission characteristics of copper coated diesel engine and performance evaluation. An experimental investigation is carried out on twin cylinder, water cool, 1500 RPM constant speed type vertical diesel engine. The cylinder heads surfaces, engine pistons top surfaces and engine valves surfaces were coated with copper material by electroplating processes with 400 microns thickness. The diesel engine combustion chamber inner walls insulated by electroplating copper coating. The performance and exhaust emission were compared with base engine and without copper coated diesel engine. The results strongly indicate that slightly improvement on performance and better improvement of exhaust emission. It is observed that the reduction in NOx and smoke level for Copper catalyst coated combustion chamber. It is also indicate that to change the coating technology and adopt, bimetallic ceramic thermal barrier coating (TBC) concept.
