This paper is an attempt to present the performance analysis of dual biodiesels pongamia oil and cotton seed oil at different blending ratios with diesel (B10=10% of biodiesel, B20=20% biodiesel, B30=30% of biodiesel). Performance of duel biodiesel and exhaust temperatures were examined in a single cylinder VCR diesel engine with electrical dynamometer by direct injection, at various engine loads with an average engine speed of 1550rpm. The influences of blends on break power, break thermal efficiency, specific fuel consumption, air fuel ratio and exhaust temperatures were investigated and compared with mineral diesel. The brake thermal efficiency of blend B10 was found higher than diesel. The exhaust gas temperature for dual biodiesel blends was lower than diesel.

Keywords: Duel biodiesel, pongamia oil, cotton seed oil, performance analysis of dual biodiesel
