Abstract

A security device for an internal combustion engine comprising a valve for installation in either the air inlet, fuel inlet or exhaust outlet of the engine, and a lockable valve control mechanism. When installed, the valve is operable from within the cabin of the vehicle by means of the valve control mechanism to open or close the valve. The valve control mechanism can be locked with the valve in the closed position so that when a thief attempts to start a car in which the device is installed, the engine won't start or if it does it won't run for long.
