The main function of the
Cummins generator set coolant temperature gauge is to indicate the temperature of the engine coolant, ensuring that the engine operates within the optimal temperature range, thereby protecting the engine and optimizing vehicle performance.
Working principle of coolant temperature gauge
The coolant temperature gauge senses the temperature of the coolant through a sensor and transmits the data to the dashboard for display. This sensor is usually located in the radiator or water pipe of the coolant system. When the engine starts, the coolant pump begins to circulate coolant, and the sensor senses the temperature and transmits data to the temperature gauge display screen on the dashboard through wires, displaying the coolant temperature in the form of numbers, ribbons, or warning lights.
Normal operating range of coolant temperature gauge
The normal operating range of a coolant temperature gauge is usually between 80-100 ° C. When the engine is working normally, the coolant temperature should be maintained between 80-100 ° C. If the temperature is too high or too low, it will cause damage to the engine. Excessive temperature may cause the coolant to boil and damage internal engine components; If the temperature is too low, it will affect the combustion of fuel and the acceleration performance of the vehicle.
The relationship between coolant temperature gauge and other systems
The coolant temperature sensor not only provides temperature signals to the coolant temperature gauge, but also provides signals to the ECU (Electronic Control Unit) for correcting fuel injection and ignition timing. In addition, the coolant temperature sensor signal is also used as a control signal for other control systems, such as the EGR system.
