Abstract
In this study, a spark ignition engine operated with LPG and DME blended fuel was studied experimentally. Performance and emissions characteristics of a LPG engine fuelled by LPG and DME blended fuel were examined. Results showed that stable engine operation was possible for a wide range of engine loads within 20% mass content of DME fuel. Also, engine output power within 10% mass content of DME fuel was comparable to pure LPG fuel operation. Exhaust emissions measurements showed that hydrocarbon and NOx were increased with the blended fuel at low engine speed. Engine output power was decreased and break specific fuel consumption (BSFC) was severely increased with the blended fuel since the energy content of DME was much lower than that of LPG. Considering the results of engine output power and exhaust emissions, the blended fuel within 20% mass content of DME could be used as an alternative fuel for LPG.
