模拟高原环境下无灰助燃剂对柴油机性能的影响

在大气模拟试验装置上进行了模拟高原环境下柴油机燃用0号柴油和添加无灰助燃剂燃油（1号柴油）的发动机台架试验，通过测试功率、燃油消耗率、碳烟等有害物质排放量来评价柴油添加剂节能减排功效。结果表明，柴油机在模拟海拔3 000 m气压（70 kPa）条件下，与燃用0号柴油相比，燃用1号柴油时发动机输出功率升高，燃油消耗率及CO、HC、碳烟排放量降低，NOx排放量略有增加。添加无灰助燃剂可有效提升柴油机的动力性、节省燃料和降低排放，改善发动机的高原适应性。

Effect of Ashless Combustion Supporting Additive on Diesel Engine Performance Under Simulated Plateau Environment

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.
