在水温正常的情况下，柴油机机油温度高出水温５℃以上，则说明机油温度过高。具体表现有以下十个方面： １、油温调节开关的位置不对，机油不经过散热器散热，导致机油温度高于水温。 ２、安全阀弹簧弹力减弱或折断，安全阀及阀座磨损，没封闭严；安全阀被杂物垫起等，使机油 In the case of normal water temperature, diesel engine oil temperature above the water temperature above 5 ℃, then the oil temperature is too high. Specific performance in the following ten aspects: 1, the location of the oil temperature adjustment switch is wrong, the oil does not heat sink, causing the oil temperature is higher than the water temperature. 2, safety valve spring weakened or broken, safety valve and seat wear, no closed strict; safety valve was padded pad, so that the oil
