The Impact of Ethanol Contents on Combustion Performance and Nano-particle Emission Characteristics from Spark Ignition Direct Injection (SIDI) Engine

에탄올 함량비가 SIDI 엔진의 연소성능과 입자상물질 배출특성에 미치는 영향에 대한 연구

Ethanol as fuel of Spark Ignition Direct Injection (SIDI) engine has become a feasible alternative due to its better anti-knock characteristics and lower nano-particle emission level. There are a number of studies on the emission characteristics from SIDI engine fuelled with various ethanol contents. In general, increase of ethanol contents leaded to decrease of nano-particle discharge, but the other researches showed reversed result at a singular range of ethanol contents. This study focused on the engine combustion performance and nano-particle emission characteristics of SIDI engine fuelled with intermediate ethanol contents.
