Performance and Emission Characteristics of Cardanol Hybrid Biofuel Blend with Diesel

As a renewable, sustainable and alternative fuel for common rail direct injection engines, biodiesel instead of diesel has been increasingly fuelled to study its effects on engine performance and emission in the recent years. In this present study karanja oil biodiesel, cotton seed oil biodiesel and cardanol oil are blended with diesel which are used as biofuels. The blends with diesel were in the ratio of 25% and 40%.Experimental study was made for performance and emission characteristics on single cylinder,4 stroke CRDI engine. The engine test as carried at constant speed of 1500rpm, at a compression ratio of 17:5:1 at an injection pressure of 350bar for different loads. It was found that performance and emission characteristics of the engine with respect to load factor for 25% blend and 40% blend. They show that BP closer to diesel, higher BTHE, lower BSFC, lower CO and HC emission at peak load. Hence above cited Biofuel are acceptable to use them as alternative fuel in CRDI engine but for 40% blend certain modification factors has to be considered for the engine.
