(1) Diesel fuel should be stored for at least 48 hours before being added to the Chongqing refrigerated truck fuel tank.

(2) Before each operation, turn on the oil drain switch of the refrigerated truck's fuel tank to drain the sediment at the bottom of the tank.

(3) During the operation, attention should be paid to the oil storage in the fuel tank to prevent air from entering the fuel system due to the depletion of oil storage, which may affect the normal operation of the machine.

(4) Add diesel after work every day to prevent water droplets from condensing on the inner wall of the empty fuel tank from sinking into the diesel, causing premature rusting of the accurate coupling components of the fuel system.

(5) Let's talk about refrigerated truck manufacturers who often unclog the vent hole of the fuel tank cap to prevent negative pressure in the tank, reduce fuel delivery pressure, decrease fuel supply, and cause a decrease in machine power or unstable operation.
