AUTOMATIC FUEL CHANGE CONTROL DEVICE

摘要

PURPOSE: An automatic fuel change control device is provided to improve startability when fuel supply is automatically converted and to obtain economical effect by compacting structure. CONSTITUTION: An automatic fuel change control device includes: an ECU(Electronic Control Unit)(200) controlling the flow of the operating oil; a switching-over valve(201) for the selection of a gasoline mode and an automatic mode; a water temperature switch(202) turned on and off depending on the temperature of the cooling water; a CPU(Central Processing Unit)(203) outputting a control signal by receiving the input data of the water temperature switch; a first relay(206) turned on and off by the control signal of the CPU; a gasoline pump(208) selectively operated by the on/off signals of the first relay with an injector protecting device(209); a second relay(207) operated by the control signal of the CPU; an LPG(Liquefied Petroleum Gas) solenoid valve(210) selectively operated by the on/off operation of the second relay; and a display unit(205) indicating the flow rate of fuel. The use of fuel is automatically changed when converting to the automatic mode from the gasoline mode. Therefore, startability is improved while convenience is realized. By reducing the number of valves, economical effect is obtained.
