The effect of diesel-biodiesel blends on the performance and exhaust emissions of a direct injection off-road diesel engine
This paper presents a comparative analysis of the diesel engine performance and emission characteristics, when operating on diesel fuel and various diesel-biodiesel (B10, B20, B40, B60) blends, at various loads and engine speeds. The experimental tests were performed on a four-stroke, four-cylinder...
