Vehicle anti-theft device using fuel cut method

摘要

The present invention relates to a vehicle anti-theft device using a fuel cut-off method for driving a lamp and an alarm when the vehicle is stolen to output a warning signal and simultaneously cut off fuel supplied to the combustion chamber to prevent starting of the vehicle. That is, in a vehicle having a fuel tank 7 filled with fuel and a fuel filter 6 for filtering fuel supplied from the fuel tank 7 to the fuel injector 5 installed in the engine, the remote controller ( 2) the engine electronic control device 1 for operating the switch SW by receiving the operation signal of the anti-theft sensor 3 connected to 2) and the power supply of the battery 4 according to the operation state of the switch SW. And a switch SW for supplying the solenoid valve SV to the solenoid valve SV and a solenoid valve SV for interrupting the fuel supplied from the fuel tank 7 to the fuel injector 5 by receiving the power of the battery 4. Thus, as well as outputting an alarm signal for notifying when the vehicle is stolen, it is possible to prevent the vehicle from being stolen by blocking the start of the vehicle.
