Abstract:This paper presents a study on the effect of the ratio of biodiesel on performance and emissions of diesel engines. Researching engine is a cylinder engine AVL-5402 is simulated by software AVL-Boost. Simulated fuel include fossil diesel and biodiesel blended with the replacement rate from 0% to 50%, simulation mode in 1400 (rev/min) at the rate of 25%, 50% and 75% load. Parameters to be evaluated as power, fuel consumption and emissions 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, the ratio of biodiesel blend increases, the tendency reduces engine power, increase fuel consumption. The emissions of CO and soot reduces, while NOx increasesKeywords: engine simulation, biodiesel, emission, mixing ratio
