研究了柴油机燃料泄漏后在热壁上的着火，利用统计方法得到着火的临界温度。发现样品燃料的热壁着火温度与自燃点的差值比其它燃料热壁着火的相应值要小得多，而且着火方式也有很大差异。详细解释了泄漏后的液体在热表面上的沸腾蒸发模式，给出了燃料蒸气的质量流率推导公式。

The ignition of leaked fuel of the diesel engine is studied experimentally. The critical ignition temperature is calculated statistically. The difference between the ignition temperature and auto - ignition temperature of diesel is much less than that of other fuels. The ignition mode is also much different from its counterpart. The paper describes the detailed boiling mode of the leaked fuel on a hot surface. The equation to get the mass flux of the fuel vapor is given.
