Effect of ZrO2-Al2O3 and SiC Coating on Diesel Engine to Study the Combustion and Emission Characteristics 2009-01-1435

The experimental study of the effect of thermal barrier coating on combustion, performance and emission of a diesel engine was investigated. The thermally insulated pistons were compared with standard engine. In general, thermal barrier coating improves the efficiency of the engine and reducing the various energy losses. The experiment was conducted in a single cylinder water cooled DI diesel engine. The results indicate that SiC coated engine shows maximum reduction of NOx emission compared to ZrO2-Al2O3 coated engine and standard engine. By the effect of coating, performance of the engine is slightly increases and smoke density is also slightly enhanced. The second part of the investigation is blending of 2-methoxyethyl acetate (MEA) additive with sole fuel, plus thermal barrier coated engine. The combined effect of thermal barrier coating plus fuel additive shows better performance and simultaneously reduces the smoke and NOX emission.
