汽油与柴油掺兑用作柴油机应急燃料的试验研究

将不同比例的车用汽油掺入柴油中，进行实验室理化性能分析和发动机台架外特性试验分析。结果表明，柴油中掺入车用汽油后，对发动机功率、扭矩、平均爆发压力影响较大，使动力性能下降，燃料消耗率升高，排气烟度降低。对于柴油机来说，汽油与柴油混合油只能作为应急燃料使用，不能长期使用。应急燃料对于提高战时油料保障能力具有重要意义。

A RESEARCH OF BLENDING GASOLINE IN DIESEL FUEL FOR EMERGENCY USE

Emergency fuel plays an important role in oil supply during war time. A research of blending gasoline in diesel fuel with various proportions was carried out to analyze the physicochemical properties of the mixed fuels and to evaluate their engine test performance. It was found that diesel fuel blended with a certain amount of gasoline could be used as emergency diesel fuel, yet it could not be used for long since the engine power, twisting moment couple and average eruptive pressure were significantly affected, resulting in poor engine power performance, increase of fuel consumption and etc.
