  2. OPERATION


    1. A recirculation type fuel heater is used. This heater heats the fuel by recirculating the returned fuel, which is given a high temperature by the fuel pumping of the supply pump, to the fuel filter.

    2. While the engine is cold, the recirculation valve inside the fuel heater opens due to the bimetal action, so the return fuel returns to the fuel filter and the fuel tank.

    3. While the engine is warm, the recirculation valve closes due to the bimetal action, so all the return fuel returns to the fuel tank.
