Combustion and performance parameters of a Diesel engine operating on ethanol-Diesel fuel blends

The article presents bench test results of a DI (60 kW) Diesel engine D-243 operating on class 2 Diesel fuel (DF) as baseline fuel and its 5vol%, 10vol% and 15vol% blends with anhydrous ethanol. The purpose of the research was to investigate the effect of the ethanol addition to Diesel fuel on the autoignition delay, combustion, engine performance efficiency and emissions of the exhaust. The results of engine operation on ethanol- Diesel blends are compared with baseline parameters of normal Diesel running at full (100%) load and rated 2200 rpm speed.
