Abstract

A vehicle misfuelling apparatus is disclosed for use with a fuel pump having at least one fuel nozzle 1. The apparatus comprises a transmitter 7 for transmitting a data signal, located on the bodywork of a vehicle, adjacent to the fuel tank inlet 2 and a receiver 5, located on the fuel nozzle 1 adjacent the handle 3 of the fuel pump. The data signal may contain a unique fuel code which represents the type of fuel required by the vehicle whilst the receiver 5 may have a predetermined set of stored data that represents the type of fuel dispensed by the fuel nozzle 1. When a motorist presents the fuel nozzle 1 to the fuel tank inlet 2, the receiver 5 will receive the data signal transmitted by the transmitter 7 and alert the motorist by means of an indicator if the data signal does not match the stored data, thereby providing an indication that the fuel dispensed by the fuel nozzle is not the type of fuel required by the vehicle. The receiver 5 can also be connected to the fuel pump in order to prevent the wrong type of fuel from being dispensed.

Description

TITLE
Vehicle misfuelling alert apparatus
DESCRIPTION
Technical Field
The present invention relates to an apparatus designed to prevent a motorist from filling his or her vehicle with the wrong type of fuel.
Background Art
The accidental misfueling of vehicles (i.e. filing a vehicle with the wrong type of fuel) is a major concern for motorists because it can cause serious damage to the vehicle's engine. The Automobile Association reports that it was called out to 37,000 misfuels in 2001 alone ("The AA Magazine", Spring 2002, page 10). The only solution is to completely empty the fuel tank and the discarded fuel alone costs motorists around ú18 million a year.
Some mechanical solutions to this problem are known. EP 1199208 (Bayerische Motoren Werke AG), for example, discloses a fuel tank inlet (or fuel nozzle entry point) with a tubular slide which has the same diameter as a diesel fuel nozzle. The slide is biased towards the top of the fuel tank inlet so that it closes off an air outlet, but is pushed down to open the air outlet when a diesel fuel nozzle is inserted. If a petrol fuel nozzle is inserted, it is too narrow to move the slide and it is impossible to fill the fuel tank.
The purpose of the present invention is to provide an alternative solution that can be applied to a wide range of vehicles and fuel pumps, without needing substantial redesign of either the fuel nozzle entry point or the fuel nozzle itself.
Summary of the Invention
The present invention provides a vehicle misfuelling alert apparatus for use with a fuel pump having at least one fuel nozzle, the apparatus comprising: a transmitter for transmitting a data signal, and - 2 a receiver for receiving the data signal, wherein one of the transmitter and the receiver is positioned on the bodywork of a vehicle adjacent the fuel nozzle entry point of the vehicle, and the other one of the transmitter and the receiver is positioned on the fuel nozzle, such that when a motorist presents the fuel nozzle to the fuel nozzle entry point of the vehicle, the receiver will receive the data signal transmitted by the transmitter and alert the motorist by means of an indicator, and/or prevent the fuel from being dispensed by the fuel pump, if the data signal does not match a predetermined set of stored data.
The one of the transmitter and the receiver that is positioned on the bodywork of the vehicle can be powered by the vehicle's electrical supply. Power can also be provided by a battery such as a lithium cell or similar. In this case, the one of the transmitter and the receiver that is positioned on the bodywork of the vehicle may include an indicator for alerting the motorist when the battery power is low.
The one of the transmitter and the receiver that is positioned on the fuel nozzle can be powered by the fuel pump's electrical supply. It will be readily apparent that the electrical supply must be connected to the transmitter in such a way that there is no risk of an electrical spark igniting the fuel vapours. The one of the transmitter and the receiver that is positioned on the fuel nozzle can also be powered by a battery such as a lithium cell or similar.
The indicator for alerting the motorist can be a light or a sounder.
The transmitter and receiver preferably transmit and receive an infrared optical data signal. However, other frequency data signals can be used depending on the circumstances. Rigorous safety testing may be required for certain data signals because of the risk of stray electromagnetic fields igniting fuel vapours.
The data signal preferably contains a synchronising code and a unique fuel code. - 3
The receiver may also alert the motorist by means of a second indicator if the data signal does match the predetermined set of stored data. The second indicator can be a light or a sounder. For example, the receiver can light a green light emitting diode (LED) if the data signal matches the predetermined set of stored data (i. e. indicating that the fuel nozzle will dispense the correct fuel for the vehicle) and a red LED if the data signal does not match the predetermined set of stored data (i.e. indicating that the fuel nozzle will dispense the wrong fuel for the vehicle). The first and second indicators can be provided on the transmitter but this would require some sort of signal to be sent from the receiver to the transmitter once the data signal has been compared against the stored data.
The one of the transmitter and receiver that is positioned on the fuel nozzle is preferably attached to the fuel nozzle adjacent the handle portion. The transmission range of the transmitter should be such that the receiver can receive the data signal before the fuel nozzle is inserted into the fuel nozzle entry point.
If the transmitter is positioned on the bodywork of the vehicle then the data signal (and in particular, the unique fuel code) represents the type of fuel used by the vehicle. For example, if the vehicle has a diesel engine then the data signal transmitted by the transmitter will include the unique fuel code for diesel.
Alternatively, if the vehicle has an engine which uses unleaded petrol then the data signal transmitted by the transmitter will include the unique fuel code for unleaded petrol.
If the receiver is positioned on the fuel nozzle then the stored data represents the type of fuel dispensed by the fuel nozzle. For example, if the fuel nozzle dispenses diesel then the stored data will include the unique fuel code for diesel. Alternatively, if the fuel nozzle dispenses unleaded petrol then the stored data will include the unique fuel code for unleaded petrol.
It will be readily appreciated that a single fuel pump may have more than one nozzle dispensing the same or different fuels. For example, a fuel pump may have a first fuel - 4 nozzle for dispensing diesel fuel, a second fuel nozzle for dispensing unleaded petrol, and a third fuel nozzle for dispensing leaded petrol. In this case, each fuel nozzle will have a separate receiver. Each receiver will have stored data including the unique fuel code for the particular type of fuel dispensed by its associated fuel nozzle.
Accordingly, the receiver positioned on the fuel nozzle dispensing diesel will have stored data including the unique fuel code for diesel, the receiver positioned on the fuel nozzle dispensing unleaded petrol will have stored data including the unique fuel code for unleaded petrol, and the receiver positioned on the fuel nozzle dispensing leaded petrol will have stored data including the unique fuel code for leaded petrol.
The transmitter can be positioned behind a flap covering the fuel nozzle entry point and preferably starts to transmit the data signal when the flap is opened. The transmitter can also be made to stop transmitting the data signal after a predetermined amount of time has elapsed, or when the flap is closed. Alternatively, the transmitter can include a light sensor and can be made to start transmitting the data signal when the fuel nozzle entry point is exposed to ambient light.
If the receiver is positioned on the bodywork of the vehicle then the stored data represents the type of fuel used by the vehicle. For example, if the vehicle has a diesel engine then the stored data will include the unique fuel code for diesel.
Alternatively, if the vehicle has an engine which uses unleaded petrol then the stored data will include the unique fuel code for unleaded petrol.
If the transmitter is positioned on the fuel nozzle then the data signal (and in particular, the unique fuel code) represents the type of fuel dispensed by the fuel nozzle. For example, if the fuel nozzle dispenses diesel then the data signal will include the unique fuel code for diesel. Alternatively, if the fuel nozzle dispenses unleaded petrol then the data signal will include the unique fuel code for unleaded petrol.
The transmitter can be made to start transmitting the data signal when the fuel nozzle is withdrawn from its cradle on the fuel pump. The transmitter can also be made to - 5 stop transmitting the data signal after a predetermined amount of time, or when the fuel nozzle is returned to its cradle.
An important aspect of the present invention is the ability to prevent the fuel from being dispensed if the data signal does not match the predetermined set of stored data.
To achieve this, the one of the transmitter and receiver that is positioned on the fuel nozzle can be connected to the pump apparatus of the fuel pump so that it can shut down or control the operation of the pump apparatus in the event of a potential misfuel. Alternatively, the transmitter or receiver can be connected to the fuel pump's electronic control system.
It is generally preferred that the transmitter is positioned on the bodywork of the vehicle adjacent the fuel nozzle entry point and the receiver is positioned on the fuel nozzle. However, if the positions of the transmitter and receiver are reversed then the receiver may transmit a signal to the transmitter if the data signal does not match the predetermined set of stored data so that the transmitter can control the operation of the fuel pump.
The present invention also provides a method of preventing the misfuelling of a vehicle comprising the following steps: providing one of a transmitter and a receiver on the bodywork of a vehicle adjacent the fuel entry point of the vehicle; providing the other one of the transmitter and the receiver on the fuel nozzle of a fuel pump; transmitting a data signal from the transmitter to the receiver; and alerting the motorist by means of an indicator, and/or preventing the fuel from being dispensed by the fuel pump, if the data signal received by the receiver does not match a predetermined set of stored data. - 6
Drawing Figure l shows a vehicle alert misfueling apparatus according to the present invention.
The operation of the present invention will now be explained with reference to Figure l which shows the fuel nozzle l of a fuel pump and the fuel tank inlet 2 (or nozzle entry point) of a vehicle. The fuel nozzle l has a handle portion 3 and a nozzle portion 4. An infrared optical receiver 5 is secured to the nozzle portion 4 by means of a cylindrical collar 6. The receiver 5 is connected to the fuel pump's power supply.
An infrared optical transmitter 7 is positioned on the inside of a flap 8 covering the fuel tank inlet 2. The transmitter 7 is connected to the vehicles power supply.
When the motorist opens the flap 8 to expose the fuel tank inlet 2, a light sensor (not shown) triggers the transmitter 7 to start transmitting an infra-red data signal. The data signal is a repeating bit stream containing a synchronizing code and a unique fuel code. The receiver 5 uses the synchronizing code to calculate the timing of the signal pulses and to synchronise the start of the bit stream. The unique fuel code is a five bit code and represents the type of fuel used by the vehicle. For example, the unique fuel code for diesel is l lOl l and the unique fuel code for unleaded petrol is lOOl 1.
A predetermined set of data is stored in the receiver 5. This data is a five bit code and represents the type of fuel dispensed by the fuel nozzle. The stored data for any given type of fuel must correspond to the unique fuel code for that fuel type. For example, if the fuel nozzle dispenses diesel then the stored data is l l 0 l l and if the fuel nozzle dispenses unleaded petrol then the stored data is l 00 l l.
As the motorist presents the fuel nozzle l to the fuel tank inlet 2, the receiver 5 will receive the data signal and will compare the unique fuel code against the stored data.
If the unique fuel code matches the stored data then the type of fuel dispensed by the fuel nozzle is the same as the type of fuel used by the vehicle. The receiver 5 will then light a green light emitting diode (LED) (not shown) to show the motorist that - 7 the fuel type dispensed by the fuel nozzle is correct. If the unique fuel code does not match the stored data then the type of fuel dispensed by the fuel nozzle is not the same as the type of fuel used by the vehicle. A misfuel is therefore about to occur and the receiver 5 will light a red LED (not shown) and cause a sounder (not shown) to give out an audible alarm to the motorist. The receiver 5 can also control the fuel pump not to dispense the incorrect fuel. - 8
