发动机由于使用年限过长或者保养修理不当造成机油内漏,使机油压力降至标准值以下的现象屡见不鲜,因此出现烧瓦事故也时而有之。机油内漏从机油压力表上可以看出来,其表现是冷车机油压力足够,随着机油温度的升高,机油压力逐渐下降。虽然很容易确定内漏是造成机油压力过低的根本原因,但寻找具体的内漏处却是一件不容易的事。过去曾用过拆下油底壳,加长机油泵吸油 Engine due to the service life is too long or improper maintenance caused by oil leakage, so that the oil pressure dropped below the standard value of the common occurrence, so there are occasional occurrence of burning tile accident. Oil leakage from the oil pressure gauge can be seen on the performance of the cold oil pressure is sufficient, with the oil temperature, oil pressure gradually decreased. Although it is easy to determine that internal leakage is the root cause of low oil pressure, finding a specific leak is not easy. Used to remove the oil pan in the past, to extend the oil pump oil
