Influence of Thermal Barrier Coatings on 4 Stroke Single Cylinder Diesel Engine Performance

Thermal barrier coating play a very significant role in the performance prediction. These prospects of improving the design and performance have generated impetus to active research on adiabatic or more appropriately, low heat rejection (LHR) or insulated engines. So with this aim, this experiment presents concept of thermal barrier ceramic coating in Internal Combustion engines. This experiment will aim to study effect on performance and emissions results of with & without coating for four stroke single cylinder diesel engine. The engine was thermally insulated by coating some parts of it, such as piston, exhaust and intake valves surfaces with TAFA95MXC material having 450µm thickness. The modified condition (coated parts) increase 2.12% thermal efficiency,fuel consumption decrease about 6.48%, exhaust gas temperature can be increase up to 11.42 %, CO reduced by 14.28%, HC reduced by 2.12% and NOx increased by 8.43 % compare to unmodified (original) condition.
