Abstract: This paper presents an investigation into the effect of biodiesel blending on emissions and efficiency in a stationary diesel engine. Rapeseed based biodiesel blended in increments of 25% with fossil diesel. The emissions of CO₂ show a decrease in emission (g/kWh) with increased engine load. Within the range of tests carried out, the NO_x emissions from biodiesel and its blends proved to be higher than those of petro-diesel fuel. Furthermore, in this study a correlation was found relating the NO_x emissions and the flame temperature. The efficiency of the system is improved with increased biodiesel content in the fuel. As predicted, the results for CHP show a considerable improvement to the overall efficiency. [Received: January 22, 2011; Accepted: March 7, 2011]
