摘要

对陶瓷涂层柴油发动机(YSZ)进行了性能、排放和燃烧研究，该发动机以芒果籽油(MSBD)和松节油(MSBTO)混合的生物柴油为燃料。性能研究表明，由于MSBD和MSBTO共混物的密度和粘度更高，其BSFC值比陶瓷涂层发动机中DF的BSFC值高3.6%和7.1%。与其他燃料相比，涂层发动机中DF的最大制动热效率为28%，这是由于DF的密度较低，燃料消耗较少。排放特性表明，与涂覆发动机的DF相比，MSBTO燃料的烟密度、NOx和CO分别降低了12%、15.2%和29.1%。然而，由于MSBD和MSBTO的发热量低于DF，在陶瓷涂层发动机中，MSBD和MSBTO在满工况下的UBHC释放量比DF多17%和21%。燃烧研究表明，MSBD和MSBTO燃料的气缸压力比涂层发动机中的DF低，MSBTO燃料的气缸压力比涂层发动机中的DF低5.3%，这是由于热释放较少和十六烷值较低。油缸压力的变化趋势与之相似，涂膜发动机中MSBTO的油缸压力比DF低7.4%。

Investigating the Performance, Reduction of Emission and Combustion Characteristics of YSZ Coated D.I.Diesel Engine Powered by Binary Bio-fuels

Performance, emission and combustion studies were carried out on the ceramic coated diesel engine (YSZ) fed with biodiesel obtained from the oil derived from the mango seeds (MSBD) and MSBD blended with turpentine oil (MSBTO). The performance study showed that the MSBD and MSBTO blends showed 3.6% and 7.1% more BSFC value compared to that of DF in ceramic coated engine due to higher density and viscosity. The maximum brake thermal efficiency was observed 28% for DF in coated engine compared to other fuels due to less fuel consumption of DF because of lower density. The emission characteristics displayed that the MSBTO fuel showed 12%, 15.2% and 29.1% reduction in the smoke density, NOx and CO respectively compared to that of DF in coated engine. However, the MSBD and MSBTO showed 17 and 21% more release of UBHC at full conditions compared to that of DF in ceramic coated engine due to lesser calorific values of MSBD and MSBTO compared to the calorific value of DF. Combustion study revealed that the MSBD and MSBTO displayed less cylinder pressure compared to that of DF in coated engine and the MSBTO fuel showed the 5.3% decrease in the cylinder pressure compared to that of DF in coated engine owing to less heat liberation and lower cetane value. HRR followed the similar trend of variation of cylinder pressure and the MSBTO displayed 7.4% lower HRR compared to that of DF in coated engine.
