When the engine ambient temperature is below 4°C, during the starting phase, the engine coolant/lubricating oil may condense to a solid state and lose its lubricating or cooling effect. cooling, thus damaging the engine. Therefore, it should be The engine is equipped with a heater to ensure normal starting and operation of the engine.
Heating process After the heater is turned on, the water pump runs for 5 seconds. If the water temperature does not reach the set temperature and the heater does not dry out, the heater will start heating until the water temperature is reached. reaches the set temperature, then the heater enters the automatic state; When the water temperature drops below the reset temperature, the heater will restart heating.
Dry burning judgment: when the sampling temperature of the cadry combustion temperature sensor is higher than 95°C or the difference between the sampling temperature of the dry combustion temperature sensor and the sampling temperature of the water temperature sensor exceeds the normal value, it is determined that the radiator exhibits a dry burning phenomenon. The alarm light turns on and the heater stops heating when the sampling temperature of the dry burning temperature sensor is lower than 80°C or the difference between sampling; The temperature of the dry combustion temperature sensor and the sampling temperature of the water temperature sensor are lower than the normal value, the heater alarm light goes out, and the heater switches to automatic state.
