Abstract: The present work explores the possibility of simultaneous reduction of NOx and smoke of a stationary CI (compression ignition) engine fuelled with biodiesel blend. Fuel injection timing is retarded which resulted in lower NOx emission with an increased smoke intensity. NOx emission of the biodiesel at the standard and retarded injection timing was predicted with the help of developed correlations and the same was compared with the NOx emission experimentally determined. It was observed that the predicted NOx emission of biodiesel is comparable with the experimentally determined. Fuel injection pressure was increased at the retarded injection timing and its effect on NOx and smoke emission was investigated. It was observed that the increase in smoke intensity resulting from the retarded injection timing was reduced significantly by increasing the fuel injection pressure.
