介绍作者开发的一种汽油机用新型燃料，为检验其品质，对发动机缸内过程参数进行了全面测试分析。结果表明：汽油机燃用轻油基混合燃料时无爆震，动力性稍低于燃用汽油，缸内过程参数标准偏差明显低于燃用汽油。这充分说明，所开发的轻油基混合燃料品质优良，适于汽油机使用。

A kind of new fuel suitable for gasoline engine is developed in this paper. To check its quality, a series of tests on process parameter in cylinder are done. The test results show that the power of engine with light oil-based fuel is close to that with gasoline and the standard errors of process parameter in cylinder with light oil-based fuel are lower than that with gasoline. This proves that the light oil-based fuel has good quality and is suitable for gasoline engine.
