Abstract:

Using an atmosphere simulation test device, the engine bench test under simulated plateau environment was carried out when the diesel engine was fueled with fuel(NO.0) and adding ashless combustion supporting additive fuel(NO.1). By testing the power, the fuel consumption rate, the emissions of soot and other harmful substances, to evaluate the effect of energy-saving and emissions reduction of diesel additive. The results indicated that in comparison to fuelled with NO.0, when the engine fuelled with NO.1 at simulated altitude of 3 000 m (70 kPa), the engine output power increased, the fuel consumption rate and CO,HC,soot emission decreased obviously, while NOx emission increased slightly. Add ashless combustion supporting additive can effectively improve the power of the diesel engine, save fuel and reduce emissions, improve the plateau adaptability of the engine.
