Experimental investigation of IC engine performance using calophylum inophylum biodiesel

Abstract

Abstract With a higher energy demand, the cost of oil is also increasing along with that the resources are vanishing at a very high pace and such conventional fuels creates environmental pollution, thus the best option is to find some clean, viable alternative for the same. Biodiesel is an available option and thus a better substitute for the IC engine fuel, It majorly restricts high emissions of the Carbon Monoxide(CO), Particulate Matter (PM), Hydrocarbon (HC) emission. Perversely, a number of experiments are conducted on a single blended bio fuel. This paper concentrates on two different bio-fuel blends with diesel. Calophylum Inophylum oil used for controlling the emission from the exhaust and subsequently improves the performance of an engine. The parameters are as follow: Brake thermal efficiency (BTE), specific fuel consumption and exhaust emission were noted. Lower the blends of biofuel more will be the thermal efficiency and thus it too reduces the specific fuel consumption. Calophylum Inophylum oil is used to prepare biodiesel blends ie (B20 and B40). The combustion characteristics investigated are cylinder gas pressure and heat release rate. Investigation is carried out at various loads and varying crank angles. The emissions at exhaust end were decreased while an increase was noted when the parts of biodiesel in the blend formed. This itself is sufficient to prove the viability and potential of the biofuel as an alternative to the conventional fuel being used to run an IC engine.
