Simulation Study on the Effect of Biodiesel Ratio Derived from Waste Cooking Oil on Performance and Emissions of a Single Cylinder Diesel Engine

This paper presents a study on the effect of the biodiesel ratio on the performance and emissions of diesel engines. The research engine is a cylinder engine AVL-5402 that has been simulated using the software AVL-Boost.Simulated fuels include fossil diesel and biodiesel blended with the replacement rate from 0% to 50%, including B0, B10, B20, B30, B40, and B50, respectively, simulation mode at 1400 rev/min speed for maximum torque value of the engine, at the rate of 25%, 50%, and 75% load. Combustion characteristics, power, fuel consumption, and emissions are to be evaluated based on the proportions of blended biodiesel. The results show that there is a relationship between the proportion of blended biodiesel and the parameters of the engine. Specifically, as the ratio of biodiesel blend increases, peak pressure and rate of heat release decrease while peak temperature increases, the tendency to reduce engine power and increase fuel consumption increases. The emissions of CO and soot are reduced, while NOx is increased.
