Abstract

This paper presents an experimental study of the effects of LPG fuel blending in different ratio (0, 10%, 15%, 20%, and 25%) with pure naphtha or pure gasoline on engine performance and emissions. The LPG fuel blended is done on energy replacement basis. The experiments were carried out on four stroke spark ignition engine, single cylinder and air cooled at constant compression ratio and constant engine speed of (2500) rpm under different loads. The variations in brake specific fuel consumption, brake thermal efficiency, volumetric efficiency and equivalence ratio were examined. There is a marked improvement in brake thermal efficiency and brake specific fuel consumption when LPG fuel blending was used as compared to pure naphtha or pure gasoline where best results were obtained at using 20% LPG blending. For the volumetric efficiency and equivalence ratio the results were negative at all LPG ratio levels where addition of LPG fuel leads to a decrease in volumetric efficiency and increase in equivalence ratio.  An improvement in the exhaust gas emissions concentration levels for (CO, CO2 and NOx) with increasing in LPG fuel blending where it significantly decreases except HC concentration which increases due to the way of LPG injection into the engine
