The high oil temperature may be caused by the failure of the oil cooling system or the high engine temperature. The high engine temperature may be caused by the problem of the engine cooling system. Engine oil is very important for automobile engine. Engine oil not only plays the role of lubrication in the engine, but also plays the role of cleaning, sealing, cushioning, rust prevention and heat dissipation.

機油溫度105度正常嗎

Is the oil temperature 105 ℃ normal

發(fā)動機的機油溫度和冷卻液溫度是不同的，冷卻液溫度保持90度左右是好的狀態(tài)，而機油溫度就不同了，機油溫度在100-130度左右都是正?，F(xiàn)象，所以機油溫度105度是正常的。

The engine oil temperature and coolant temperature are different. It is good to keep the coolant temperature at about 90 degrees, but the oil temperature is different. It is normal for the oil temperature to be about 100-130 degrees, so the oil temperature of 105 degrees is normal.

機油的主要作用有潤滑、清洗、密封和散熱。發(fā)動機在運轉過程中會產生大量熱量，其中一部分熱量直接通過冷卻液進行散熱，而不能直接和冷卻液接觸的零件就需要通過機油進行散熱，機油在通過機油散熱器和冷卻液做熱交換來散熱，所以機油的散熱效率就不能像冷卻液那么高，正常情況下機油溫度都要高于冷卻液溫度的。

The main functions of engine oil are lubrication, cleaning, sealing and heat dissipation. During the operation of the engine, a large amount of heat will be generated. Part of the heat will be dissipated directly through the coolant, while the parts that cannot directly contact the coolant need to be dissipated through the oil. The oil is dissipated through heat exchange between the oil radiator and the coolant, so the heat dissipation efficiency of the oil can not be as high as that of the coolant, Under normal circumstances, the oil temperature should be higher than the coolant temperature.

很多車主不太了解認為機油溫度高是不是對發(fā)動機不利，其實機油對溫度的適應能力要遠遠超過你的想象。機油的性能參數(shù)有一個高溫抗剪切能力，這個是在機油150度條件下測量的，也就是說，機油就算達到150度，也需要達到一定抗剪切值，所以機油溫度在130度以下都很正常的，沒必要擔心這個問題。

Many car owners don't know whether high oil temperature is bad for the engine. In fact, the adaptability of oil to temperature is far more than you think. The performance parameters of engine oil have a high-temperature shear resistance. This is measured under the condition of 150 degrees of engine oil, that is, even if the engine oil reaches 150 degrees, it needs to reach a certain shear resistance value. Therefore, it is normal for the engine oil temperature to be below 130 degrees. There is no need to worry about this problem.
