METHOD FOR CONTROLLING OF CUT-OFF VALVE OF INJECTOR OF LPG CAR

摘要

A control method of the injector shutoff valve of the LPG vehicles is provided to prevent the injector shutoff valve from being blocked due to the injector solenoid and the foreign material inserted between injector by controlling the injector shutoff valve. A control method of the injector shutoff valve of the LPG vehicles performs the followings: a step for receiving the trigger signal supplied through ECU from the start key (S101); a step for determining whether was converted or not to on state in off-state (S103); a step for increasing the counting value of the counter which counts opening and closure control times of the injector shutoff valve (S107); a step for comparing the predetermined time stored with the counting value in advance (S109); a step for resetting the counting value of counter the comparison result counting value is the predetermined time or greater (S111); and a step for controlling the opening of the injector shutoff valve (113).
