Abstract

PURPOSE: To shorten a fuel change-over time of a fuel supply apparatus in which from high-quality fuel at the starting of a diesel engine to low-density fuel after a warming-up by provinding a fuel heater having a heat source of cooling water heat in a high-quality fuel system.
CONSTITUTION: During a starting, a warming-up running time of a diesel engine 1, a fuel change-over valve 8 is controlled by a control apparatus 23 so as to supply A heavy oil from a high-quality fuel tank 11 and a cooling water change- over valve 22 is also controlled by the apparatus 23 so as to circulate the cooling water flown into a cooling water piping 3a from the engine 1 through a high-quality fuel heater 20 and a conveyance conduit 21a and an exhaust pipe 21b. A main fuel heater 7 is stopped in its function during a starting, warming- up running time of the diesel engine 1. Accordingly, the temp. of A heavy oil rises gradually higher and higher with warming of the engine and the cooling water. Then the heavy oil is changed from A to C through a change-over valve 8. Completing the change-over, the valve 22 is controlled so as to lead the cooling water into a cooler 4 bypassing the heater 20. During a stallment of the engine, the cooling water is supplied to the heater 20 through the change-over valve 22 warming A heavy oil. Thus, the fuel change-over time can be shorten.
