engine oil temp gauge

The normal temperature when the engine is running is 70 ~ 90 degrees. Locally, it will be higher and usually will not exceed the water temperature.Generally, there is no oil thermometer for medium and low-grade vehicles, only for high-grade vehicles. The oil temperature on the instrument panel shows 70 ℃, which is the lowest position of the instrument pointer. Generally, the temperature rises to 100 ℃ after driving for more than 10 kilometers. If it is too low or too much, it is abnormal. Check that the important function of engine oil depends on an important characteristic - viscosity. Only when the oil has viscosity characteristics can it provide a protective film for the operating parts of all parts of the engine. SAE (American Society of Automotive Engineers) identifies the minimum and maximum operating temperature of automobile oil according to the oil viscosity grade.

Generally, there is no oil thermometer for medium and low-grade vehicles, only for high-grade vehicles. The oil temperature is low. Generally, there is a problem with the sensor. Eliminate the sensor problem. It is suspected that the vehicle transportation mode has not been completely deleted. Delete the transportation mode again. If the fault phenomenon still does not change. The vehicle needs to be programmed the turbocharged gasoline engine, which is widely used now, has a slightly higher normal working temperature, generally between 95 ° C and 105 ° C, due to its high degree of strengthening;

The normal working temperature of the highly intensified turbocharged diesel engine used in trucks is generally between 85 ℃ and 95 ℃. The normal working temperature of some diesel engines with thermal management system can be as high as 105 ℃. For example, Yuchai engine. Many drivers who drive this kind of car for the first time think that the engine is boiling every time they look at the water temperature meter; If it is an air-cooled engine, the temperature will be higher, generally between 120 ~ 150 ℃, which varies slightly according to different models. For example, small displacement motorcycles

The temperature of the air-cooled gasoline engine used can be as high as 150 ℃, while the temperature of the air-cooled diesel engine used by trucks is generally maintained at about 120 ℃.The oil temperature will be a little higher than the water temperature, generally between 100 ~ 110 ℃. In order to maintain the temperature of the oil, on some highly fortified engines the engine oil diffuser will be installed to dissipate the engine oil and prevent the engine oil temperature from being too high.
