Effect of Plasma Sprayed Metal Matrix Composite Coatings on Performance of IC Engine
The quest for increasing the efficiency of an internal combustion engine has been going on ever since the invention of this reliable workhouse of the automotive world. To achieve this cool giving more attention focused recently by reducing energy cost to the coolant during the power stroke of the cycle. Ceramic creating also has application as thermal barriers to improve the efficiency of the engines by reducing energy loss and cooling requirement. The main aim of the study is to evaluate the effect of ceramic coating on petrol engines effective efficiency at different engine loads and speeds. Experiments were conducted with the three cylinders multipoint fuel injection (MPFI) engine, before to know the coating conditions of the Piston, need to test the Engine at different type of Load and Speed conditions. By using the plasma coating method Ceramic layers are made of Al2O3 based on the NiCrAl bond coat by using base of the plasma coating method the same condition was tested in the ceramic coated research engine as the standard (without coating) engines. The results should be reduction in emission characteristic and an increase in effective efficiency. Index Term Ceramic, Ceramic Coating, Multipoint Fuel Injection engine and Plasma Coating Method.
