In this study, a compression ignition engine operated with LPG and Bio-diesel blended fuel was studied experimentally. The effect of Bio-diesel on performance and emissions of a CI engine fuelled by LPG/Bio-diesel fuel were examined‘ Bio-diesel fuel was blended to LPG fuel by Bio-diesel 20-60wt%. Results showed that stable engine operation was possible for a wide range of engine loads up to 30% of LPG by mass in a CI engine. Considering the results of the engine power out put and exhaust emissions, blended fuel up to 30% of LPG by mass can be used as an altemative to diesel in a CI engine. Bio-diesel blended LPG fuel is expected to have potential for enlarging the Bio-diesel market.
