Abstract

Investigations were carried out to study the combustion characteristics of crude rice bran oil methyl ester (CRBME) derived from high free fatty acid (FFA) as a fuel for a heavy commercial vehicle (HCV) compression ignition (CI) engine . A four stroke, 6 cylinder direct injection 117.6 kW turbo-charged engine was used for the work. Tests were conducted at different speeds and torques starting from idle condition. It was observed that cylinder pressure variation of the engine when operating with the CRBME was comparable to that of diesel. Shorter delay period and lower peak pressure were obtained for CRBME when compared to diesel. Maximum heat release rate of CRBME was lower and occurs earlier than diesel. Experimental results show that as a fuel for a heavy commercial engine, CRBME shows comparable combustion characteristics as that of diesel and can be utilized as a substitute for diesel. When compared with other biodiesels CRBME is derived from non-edible source with more availability and hence efforts can be taken to utilize this potential of CRBME as an automotive engine fuel.
