how does oil temp gauge work

• 2022-05-20

The thermometer is temp (temperature), and the other is the oil gauge. The top is f, which means full, and the bottom is e, which means empty.

The automobile oil gauge is an indicator used to display the fuel allowance of the vehicle, which is an important basis for the driver to judge whether to refuel. The driver can help the driver to make an accurate judgment on the fuel allowance or whether the fuel gauge is normal or not by mastering the structure and identification meaning of the fuel gauge.

Oil temperature gauge working principle

The position where the oil temperature gauge Sensor is installed is usually near the oil pan or oil filter element, but no matter where it is, the oil temperature indicated is lower than the actual oil temperature in the engine. When the oil temperature decreases, the oil temperature will also rise. If a sensor is installed in the oil pan, the oil temperature indication will be 5 to 10 degrees lower than the actual temperature because the high heat engine is mixed with the lower temperature oil in the oil pan. Of course, it is still the most ideal location to install the sensor directly in the engine body, but few people will install it this way. The rise in oil temperature will cause the oil film to rupture, which will lead to poor lubrication of the parts. Generally, the maximum oil temperature gauge is around 150°C, but it is best to keep it below 110°C. The temperature of the driving oil will often exceed 120 ℃, so as soon as it exceeds the temperature, change the oil as soon as possible. In addition, the temperature in the oil pan will be lower than the actual oil temperature. The engine has a "proper operating temperature" to determine the temperature with the best working efficiency. If the temperature is low, it is safe. If the temperature is high, you should pay more attention.We need to know that the first level of engine cooling is oil, and if the engine contacts the inner wall of the cylinder, the oil can more accurately reflect the temperature of the engine. Because the best working temperature of the engine is 80 degrees, and the best working temperature of the oil is 100 degrees. Although the difference between the two is 20 degrees, this intermediate temperature will not affect anything, so since the oil can better reflect the temperature of the engine
