Biodiesel fuels have some advantages over diesel fuels which comprise reduced particulate matter, CO and unburned hydrocarbon emissions. But latest studies show that there is a slight increase in NOx with biodiesel (about 10 to 20 %) compared to diesel fuel which may become a barrier to the expansion of biodiesel as a diesel engine fuel. Recent studies have shown that the increased formation of prompt NOx is responsible for biodiesel NOx effect. Since the treatment of biodiesel with antioxidants reduces the formation of hydrocarbon free radicals, which are responsible for prompt NOx production in the combustion process, it is a promising approach for reduction of NOx emissions. This experimental study is an investigation of the effect of antioxidant additives on the emission characteristics of biodiesel fuelled diesel engine with an emphasis on the reduction of NOx emissions.
