Part Structure and Principle Introduction
The function of DEF tank is to store DEF solution and provide DEF for DPF (Diesel Particle Filter) during
the machine operates. DEF tank consists of shell, multi-functional head unit and cover. There are three
sensors in the multi-functional head unit: temperature sensor, liquid level sensor and quality sensor.
Temperature sensor detects DEF solution temperature and transports signal to ECM, when DEF temper-
ature is less than -8°C, the solenoid water valve is opened, and engine coolant enters into def tank to
prevent DEF solution from freezing, however, when DEF temperature exceeds 5°C, the solenoid water
valve is closed to block coolant entering and prevent DEF solution from being excessively heated. Fuel
level sensor detects the surplus of DEF solution and transports signal to ECM, if DEF fuel lever is less
than alarm value, the situation will trigger low fuel lever alarm and remind the operator of adding DEF.
Mass sensor detects DEF mass, if user wrong adds other oils or water,or the concentration of DEF solu-
tion is unqualified, these situations will lead to alarm and remind the operator of adding DEF.
