Importance of Performance and Emission Characteristics in Biodiesel

In this review paper, importance of a variety of performance and emission characteristics has been analysed and compared. Brake thermal efficiency, exhaust gas temperature, brake-specific fuel consumption, volumetric efficiency, mechanical efficiency, air–fuel ratio, unburned hydrocarbon emission, carbon monoxide emission, nitrogen oxide emission, brake-specific energy consumption, heat flow analysis’s parameters, friction power, and smoke emission have been discussed. The important result for the analysis and review of energy audit’s importance in diesel engine fuelled with blends have been discussed. Its idea is to get a standard energy audit method, which calculates the practicability of biodiesel blend as fuel. It has been found that it is the wastage of time to do the research of all characteristics at a glance. At initial stage, brake-specific energy consumption, heat flow analysis’s parameters, smoke opacity, and friction power have been found to be of utmost importance to estimate and access the practicability of biodiesel blends in diesel.
