Abstract
An anti-hijacking and theft prevention device for motor vehicles having a fuel restricting solenoid valve assembly including an interchangeable solenoid operated fuel restricting valve and a circuit for operating the system. The solenoid operated fuel restricting valve is installed in the vehicle's fuel line. When the ignition key is inserted into the ignition switch of a vehicle and turned to the "on" position and the engine is started, a timer will start to count down from a predetermined period of time. If the system is not disabled by activating a hidden switch during the count down period, the solenoid operated fuel restricting valve moves from an open position to a closed position. The solenoid valve has a small valve orifice which allows only a small restricted amount of fuel to flow through the valve assembly in the fuel line. While the amount of fuel is sufficient to keep the engine from stalling, the vehicle will be capable of a speed of no more than 5 to 10 miles per hour.
