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

摘要

A method for controlling a cut-off valve of an injector of an LPG vehicle is provided to minimize power consumption during opening control of the injector cut-off valve by sequentially performing opening control of the injector cut-off valve based on a predetermined cylinder bank. A method for controlling a cut-off valve of an injector of an LPG vehicle includes the following steps of: receiving a start signal applied from a start key through an ECU(101), and then closing the cut-off valve after a preset time when the start signal is not a start turn-on(105); detecting closed state of the injector cut-off valve if the start signal is a start turn-on at the above step(107), then receiving engine state information if the injector cut-off valve is closed(109,113,117,121,125); and opening the injector cut-off valve in order according to a preset order of a cylinder bank by varying a control time of the injector cut-off valve based on the engine state information from the above steps(111,115,119,123,127).
