The Search On Ethanol Fuelling for Compression Ignition Engine

Along with the rapid economic development in China, productions and sales of automobiles are growing at a high speed. The rapid development of the car market and the large increase of auto possession brought a huge demand of oil resources. The high external dependence has affected our country's energy security. The application of diesel blended the ethanol can ease the oil shortage, reduces atmospheric environment pollution and helps to realize sustainable development strategy of our country. This paper mainly conducts the research on diesel engine with ethanol fuelling, experimentally studied and analyzed the influence of ethanol blended diesel on the dynamic performance, economy performance and emission performance. The results show that Ethanol blended diesel can partially substitute diesel and effectively reduce the harmful pollutants while keeping the same power and economy.
