System for remote disabling of an internal combustion engine
First Claim
1. A system for the deliberate remote disabling of an internal combustion enginer upon receipt by the engine of a disable signal from a location remote from the engine, the system comprising:
- speed detecting and comparison circuit means for connection to the engine to detect the speed thereof and to produce therein a speed signal representative of the current speed or acceleration of the engine;
the said circuit means comparing the speed signal with a preset signal value representative of a predetermined speed or acceleration of the engine above which it may be disabled, and producing a receiver enabling signal when the speed signal represents a speed or acceleration greater than the said predetermined value;
a radio transmitter operable by an operator to produce a broadcast disable signal;
a radio receiver connected to the speed detector and comparison circuit means to receive and be enabled by the said enabling signal, and upon receipt of the said broadcast disable signal while enabled producing a disable control signal; and
disabling means for connection to the engine to disable it, the disabling means being connected to the receiver to receive therefrom the disable control signal and upon receipt thereof being operative to disable the engine.

Abstract
The invention provides a system applicable to various internal combustion engines, such as for automobiles, motorcycles, snowmobiles and outboards, to permit an authorized person, such as a police officer, to prevent their improper or illegal operation. The engine includes a detector detecting the speed of operation of the motor which is compared with a preset value. Upon an unusually high motor speed being reached a receiver is enabled for a preset period of time. During this preset period the engine can be disabled by a transmission from a transmitter operated by the police officer, preferably using a designated exclusive channel. The disabling slows the engine to an idle speed without stopping it, so that the power assist mechanisms of the vehicle remain operative to maintain normal braking and steering function.
