| 摘 要： | 以某型军用车辆柴油机为研究对象，进行了海拔4 500 m条件下的热平衡试验。在控制功率相同条件下，比较和分析了该型柴油机燃用-35号车用柴油和聚甲氧基二丁基醚型含氧燃料时的热量分配。结果表明：高原环境下柴油机燃用该型含氧燃料时，滞燃期缩短、压升率降低、冷却水和排气带走的热量降低、热效率提高，有效缓解了高原环境下柴油机后燃严重和热负荷加剧的问题，是一种适用于高原环境下聚醚型含氧燃料。

| Abstract: | A type of military vehicle diesel engine is taken as the research object for heat balance experiment in a simulated environment of an elevation of 4 500 m. The heat distributions of the diesel engines fueled with automobile diesel fuel and oligomeric polyoxymethylene dimethyl ether oxygenated fuel under the same power condition are compared and analyzed. Results show that the ignition delay period is shorten, the pressure rising rate is decreased, the heat losses in coolant and exhaust are decreased, and the heat efficiency is improved when the diesel engine is fueled with the oxygenated fuel in the simulated plateau environment. The oxygenated fuel could alleviate the engine burning delay and thermal load aggravation in plateau environment effectively. These results suggest that the oligomeric polyoxymethylene dimethyl ether is a suitable fuel for diesel in plateau environment. |
