Now the temperature sensor has been widely used in all kinds of household appliances, mechanical equipment, engine, generator will also use temperature sensor. If the temperature sensor fails, it will lead to the equipment can not be used. The following sensor expert network and we will take a look at the generator temperature sensor fault treatment methods, the role of the generator temperature sensor.
Fault treatment method of generator temperature sensor
1. High resistance fault
In the high resistance state of the water temperature sensor, the information provided to the engine ECU at any time is the cold engine status information. The engine ECU sends out low temperature fuel supply signals, which will continuously increase the fuel supply. According to the expert network of sensors, since the water temperature signal obtained by ECU is a cold vehicle signal, the fuel injection volume is increased to facilitate starting. The spark plug is often soaked in fuel, so it is difficult to start the engine, especially when the engine is hot. After start-up, rich mixture is supplied all the time, resulting in high idle speed due to rich oil.
2. Low resistance fault
In the low resistance state of water temperature sensor, the information provided to the engine ECU at any time is the heat engine status information. The engine ECU sends out normal fuel supply signals without temperature compensation. Therefore, it is difficult to start the engine, especially when the engine is cold. But once the start is successful, it can work normally without abnormal phenomenon.
Function of generator temperature sensor
Temperature sensor, commonly understood as a sensor that can receive temperature information and output available signals. First of all, let’s take a look at its role in the coolant system. All friends who have some knowledge of the diesel generator set know that the position of the coolant temperature sensor is the cylinder at the front right side. It has three main functions: one is to control the rotation of the fan; the second is to adjust the fuel supply; the third is to protect the engine and timing the injection Control. In the normal operation of the diesel generator coolant temperature range is – 40 to 140 degrees, if the coolant temperature sensor does not work, there will be engine speed and power drop problems, and even cause the generator starting difficulties and other problems, the resistance of the coolant temperature sensor in the diesel generator is mostly thermistor.
Temperature sensor can play the role of data transmission, and can adjust the temperature. There are more than one method to deal with the fault of generator temperature sensor, which needs to choose the corresponding method according to the specific situation of the fault.
