据调查,忽视曲轴箱维护主要有以下几个原因。 1.对曲轴箱通风装置作用不十分清楚,甚至认为没有它发动机照样工作,只重视尾气的排放,而对曲轴箱泄漏气体对大气的污染缺乏认识。 2.通风不能有效地进行工作,往往未造成直观明显故障,不会出现停机状况,所以通风装置不同程度地存有故障。 According to the survey, ignoring the maintenance of the crankcase mainly for the following reasons. 1. The role of the crankcase ventilation is not very clear, and even think it does not work the engine, only focus on exhaust emissions, and the crankcase leakage of air pollution on the atmosphere lack of understanding. 2. Ventilation can not work effectively, often does not result in visual obvious failure, does not appear downtime, so the ventilation device to varying degrees, there is failure.
