摘　　要：简要分析了两台475汽油机因配气正时超前而造成的"功率不足"故障现象及原因。指出机组大修和分解结合时,仅以正时齿轮上原有的正时记号作为校对配气正时的唯一依据,是造成汽油机中速"功率不足"故障的主要原因之一。The fault of ＂lack of power＂ is analysed resulted by the valve timing early. And the paper also pointed out that, It is the main result of gasoline＇ s lack of power in medium speed, for using the mark on the timing gear as the only dependence in vavle train timing, when the engine is maintained.
