Abstract
Motorists sometimes fill the tanks of their vehicles inadvertently with the wrong fuel at the service station. The result is often costly mechanical and environmental damage. By appropriately shaping the fuel pump nozzle and the vehicle fuel inlet orifice, the wrong fuel cannot be introduced into the tank, except by wilful, deliberate misuse. The invention introduces no materials or processes which make motoring less reliable or more risky than today. For example, in the figure, the larger circle represents the shape of the receiving orifice in a petrol-engine vehicle, and the dotted circle the shape of the filling pipe nozzle. The elliptical sections are the equivalent for the diesel-engine vehicle and associated filling pipe. It may be seen that the petrol filling nozzle is physically unable to enter the diesel orifice on the vehicle. The same is true for the diesel filling nozzle and petrol orifice.
Description
PATENT SPECIFICATION: MOTOR VEHICLES -ASSURING THE USE OF
THE CORRECT TYPE OF FUEL
Background
Motor vehicle filling stations typically offer petrol and diesel fuel to motorists.
An increasing proportion of motorists now use diesel-powered vehicles. It has been estimated by the UK motoring associations that as many as 120,000 cases occur each year of petrol being introduced by drivers into the tanks of their diesel powered cars, or vice versa. They are the result of absent-mindedness or lack of awareness by the drivers, and the costs and environmental impact of these errors are very high.
The claim This invention will prevent, except by wilful, deliberate misuse, a vehicle's fuel tank being filled during normal refuelling at a commercial fuel station with any fuel other than the fuel for which it has been designed.
The principle and practice of the invention As an example, this invention provides a mechanical means of preventing a fuel nozzle for diesel being introduced into the filling orifice of a petrol-engined vehicle, or of a petrol nozzle being introduced into the filling orifice of a diesel-engined vehicle.
Two basic shapes are used, the circle and the ellipse.
For the diesel vehicle, the end of the fuel nozzle from the pump is elliptical in section, and so is the top section of the filling pipe on the vehicle. The elliptical nozzle fits easily into the elliptical orifice, which is of the same form but slightly larger in section.
For the petrol-engined vehicle the fuel nozzle and filling pipe are circular in section.
The end section of the fuel nozzles and the filling pipes are sized so that neither the elliptical nozzle can enter the circular filling pipe, nor can the circular section nozzle enter the elliptical filling pipe, thus: PATENT SPECIFICATION: MOTOR VEHICLES -ASSURING THE USE OF
THE CORRECT TYPE OF FUEL
Should, for regulatory purposes, the nozzles and orifices for diesel vehicles be required to be circular and those for petrol-engined vehicles to be elliptical, rather than as described above, the principles behind this invention would still be upheld.
Beneficial features of this invention No electrical or moving parts (other than the nozzle itself) are required for this invention, so making it as safe and reliable in fuel filling as the devices in current use.
If, with the invention in place, the driver uses the wrong nozzle and demands fuel from the pump, the wrong fuel cannot enter the vehicle's fuel system and a potentially very expensive recovery will be avoided.
The invention requires very simple manufacturing changes by the fuel suppliers and car manufacturers in the form of suitably shaped ends to the fuel nozzles at the pump and to the top of the filling pipes in the vehicles. The resulting costs will be minimal to the manufacturers, the fuel suppliers or the motorist The sizes would be arranged by regulation so that current vehicles (which have circular sections at the top of the filling pipes) would still be able to receive fuel from the new section nozzles. This invention would therefore be of greatest benefit to owners of new vehicles ie those which are designed and built to meet the latest environmental standards. It would therefore be in line with the international drive to reduce carbon emissions.
PATENT SPECIFICATION: MOTOR VEHICLES -ASSURING THE USE OF
THE CORRECT TYPE OF FUEL
The principle The principle is not confined to the circle or the ellipse. If there is a need to distinguish for a further fuel, a suitably sized triangle could also be used..., or a square for a fourth type of fuel... and so on.
