Engine speed control system
First Claim
Patent Images
1. A vehicle including;
- a fuel and air supply system for supplying air and fuel to the engine;
a driver controlled throttle for controlling the fuel and air supply system for altering the speed of the engine;
a valve unit-separate to the driver controlled throttle and not operable by a driver of the vehicle for selectively allowing, preventing or reducing the supply of air and fuel to the engine;
control means for moving the valve to alter the amount of fuel and air supplied to the vehicle to thereby change the speed of the vehicle independently of the driver; and
receiver means for receiving a transmitted signal to cause the control means to move the valve for changing the speed of the engine independent of the driver.

Abstract
An engine speed control system for a vehicle such as a go-kart in order to, independently of the driver, control the speed of the vehicle includes a butterfly valve which is moved by a stepper motor (70) upon receipt of over the air signals by a receiver (60) from a control station (50). The movement of the butterfly valve alters the amount of air and fuel drawn into the engine independent of control of a throttle assembly (22, 25) operated by the driver of the vehicle. Thus, the vehicle can be slowed from a control station (50) independently of the vehicle if necessary.

5. A method of controlling the speed of a vehicle on a driveway which is being driven by a driver, the method including the steps of;
-
providing a vehicle with a driver throttle control means operable by the driver to set the speed of the vehicle;
providing a valve member in the vehicle independent of the driver throttle control means and which is not operable by the driver, the valve member being actuable to adjust the speed of the vehicle;
transmitting a signal to the vehicle from a remote location by way of wireless transmission; and
causing, by way of the transmission, the closing of the valve member independent of driver control, so as to reduce, increase or shut off supply of air and fuel to a vehicle of the engine, and whereby, the speed of the engine is thereby altered by the transmitted signal.
