Event: JSAE Spring Conference
Experiments were conducted to operate a diesel engine by using Liquefied Petroleum Gas (LPG) as a main fuel. Aliphatic Hydrocarbon (AH) and cetane enhancing additive (Di-t-butyl- peroxide hereafter DTBP) were also added to the LPG. As the result, smooth operation was achieved with the wide range of engine loads. Excellent thermal efficiency comparable to diesel fuel operation was obtained when certain percentage of AH and 1wt% of DTBP was added to the LPG. Exhaust emissions measurement showed above 30% NOx and smoke was reduced compared to diesel fuel operation.
