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 NOx 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 NOx 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]
