Abstract

A solenoid valve D is fitted in the fuel line from the fuel tank E to the engine A to be protected. When the solenoid valve D is operated it will interrupt the supply of fuel to the engine A so that the engine starts but then stalls with no indication of the reason. The closer the valve is to the engine, the quicker the engine will stall. The solenoid valve D can be controlled via several combinations of control circuits and can be used as in independent fuel immobiliser or as part of an alarm system. A manual valve may be used instead of the solenoid valve (fig.2).

Description

FUEL LOCK This invention is associated with and compliments road vehicle security.
Currently road vehicle anti theft security falls into two specific configurations a. A mechanism fitted to either the gear lever or the steering wheel, which renders the vehicle inoperative.
b. Electronic/Electrical control mechanism which interupts the ignition system of the vehicle to the extent of preventing the engine from beinq started. Some of these systems also provide an audible warning and visual warning systems.
Both of these systems provide a reasonable level of security, however both systems share the same disadvantage.
a. Electrical/Electronic mechanisms afford the thief prior warning, enabling the thief to circumvent the mechanism, in effect bypassing the control circuits.
b. Mechanical mechanisms also afford the thief time to physically remove the device.
This invention gives no indication that a security device is fitted, in fact the engine will turn and fire at first and then stall, giving no indication of why this has happened This invention is a device that interupts the fuel supply from the fuel tank to the engine, it can be either manually or elctrically operated.
The device consists of a manual or electrically operated selenoid valve, placed in the fuel circuit.
The manual valve can be placed in a convenient location in the fuel line.
The selenoid valve can be placed as close to the engine as possible and can be controlled in several control circuit combinations.
It can be used as part of an alarm system or as a stand alone immobilizer.
This invention has several desirable effects.
This will now be discribed by way of example with reference to drawings.
a. In fig 1. When selenoid valve D is operated, it cuts the fuel supply from petrol tank E, starving engine A of fuel.
The position of valve D is important, if it is placed next to fuel tank E, the engine will use the remaining fuel in the fuel line.
However if valve D is placed close to the engine, this will make the engine stall quicker.
It can be seen that the relationship between the engine A and valve D is important as the position of valve D can be adjusted to make the engine stall quicker or slower.
The length of time that engine A will run has a direct relationship to where valve D is placed in the fuel line.
b. In fig 2. The operation is the same as fig 1, but selenoid valve D is replaced with a physically operated valve, placed in a convenient position.

Claims (4)

  1. THE FUEL LOCK
    CLAIMS 1. The fuel lock comprises of a Selenoid valve, a suitable power supply, means for interrupting the power supply to the Selenoid valve.
  2. 2. The fuel lock as claimed in claim 1 wherein can be used as an independent fuel interrupter to interrupt the flow of fuel to the engine.
  3. 3. The fuel lock as claimed in claim 1, claim 2 wherein can be used in conjuction with an existing alarm or immobilizer system.
  4. 4. The fuel lock as claimed in claim 1, claim 2, claim 3, wherein if activated or deactivated will interrupt the flow of fuel to the engine to be protected, thus rendering the engine inoperative.
