APPARATUS AND METHOD FOR CONTROLLING LPG INJECTOR OF LPI CAR

摘要

An apparatus and a method of controlling an LPG injection of an LPI car are provided to block fuel supply to a malfunctioned injector to prevent fuel injection thereto, thereby preventing the LPI car from being fired. An apparatus for controlling an LPG injection of an LPI car includes a main ECU(31), a sub ECU(33), and a plurality of fuel blocking valves(35). The main ECU generates a gas injection signal through a gasoline injection line to supply the signal to the sub ECU. A plurality of fuel blocking valves are installed between the sub ECU and a plurality of injectors(17). The main ECU determines malfunction of the gas injector through the sub ECU. The fuel blocking valves control the fuel supply to the injector according to the determined result.
