介绍了在一台采用火花助燃、缸内直喷、周向分层充量的柴油机上燃用甲醇和乙醇的试验研究结 果；分析了油束的分布、油束在燃烧室中与火花塞的相对位置、火花塞间隙和喷油定时等主要参数对发 动机性能的影响。当以上参数经过优化后，发动机能在广阔的转速和负荷范围内稳定运转。同时测量与 分析了发动机燃用醇类燃料时的性能，并与原柴油机的性能作了比较。
The experimental results on the combustion of methanol and ethanol on a diesel engine using spark-assisted combustion, direct injection in the cylinder and circumferential stratified charge are introduced. The distribution of the oil bundles, the relative position of the oil jet to the spark plug in the combustion chamber Location, spark plug gap and injection timing and other major parameters of the engine performance. When the above parameters are optimized, the engine can operate stably over a wide range of speeds and loads. The performance of the engine with alcoholic fuel was measured and analyzed at the same time, and compared with the performance of the original diesel engine.
