Most investigations show that the use of biodiesel results in lower emissions of HC, CO and smoke whereas the emission of NOx increases. For this reason attention in this paper is focused on the possibility to reduce NOx emission when using biodiesel fuel. The experiments are performed on an NA diesel bus engine with direct injection M system. The tested fuels are mineral diesel and domestic biodiesel fuel produced from rapeseed. At first the influences of different fuels on NOx emission are investigated. The analysis of experimentally obtained results is performed at different engine operating regimes with the injection timing prescribed by the engine producer for mineral diesel fuel. The NOx emissions and other engine characteristics with biodiesel are compared against those obtained using mineral diesel. In this way the influences of fuel properties on engine harmful emissions, specific fuel consumption, brake thermal efficiency and engine power are investigated. Furthermore the possibility for reduction of NOx emission without expensive engine modifications is investigated. Keeping this in mind, the optimal injection pump timing is determined. The experimental results show that the retarded injection pump timing is necessary when using biodiesel in order to reduce harmful NOx emission without worsening other engine characteristics. During the experiments, the engine was monitored for possible operation problems and carefully examined after the tests.
