Experimental investigation on the effect of ceramic coating on engine performance and emission characteristics for cleaner production

Experimental investigations were carried out to explore the performance and emission characteristics of three cylinder diesel engine with its piston coated with three different ceramic coating materials namely zirconia, zirconia + aluminum oxide (Zr02 +A1203) and fused zirconia (40FZA). The coating process were done through plasma spray coating. Further the experimental results of these three candidate materials were compared and analyzed to draw the best ceramic coating material based on their engine performance and emission characteristics with the coating thickness of 0.5 mm. Finally, the results revealed that coating with fused zirconia provides better results on engine performance and emission characteristics including smoke density, rate of emission of carbon monoxide, carbon di-oxide, hydro carbon and nitric oxide. This study sought to explore the scientific relevance through analyzing the performance of the engine and encourage the cleaner production through considering carbon emissions. Conclusion of this study promoted the performance of coating material in addition with shed light on the future research opportunities exists within this area. 2018 Published by Elsevier Ltd.
