Method and System for Preventing Misfueling
First Claim
1. A method of preventing introduction of an incorrect fuel type into an engine, comprising the steps of:
- (a) wirelessly transmitting a first signal to at least one receiver, said first signal corresponding to a first fuel type designated for storage in a fuel storage apparatus;
(b) wirelessly transmitting a second signal to at least one receiver, said second signal corresponding to a second fuel type contained within a fuel dispensing apparatus, wherein said first and second fuel types are the same or different;
(c) determining whether said first and second fuel types are the same or different based on said first and second signals.

Abstract
The methods and system of the present invention provide for a means of preventing the introduction of incorrect fuel type into an engine. Data is transmitted wirelessly from a fuel storage apparatus to at least one receiver. In part, the selected data comprises the type of fuel that is required to be introduced into the fuel storage apparatus. Data is also transmitted wirelessly from a fuel dispensing apparatus to the receiver. In this case, the data comprises, in part, the type of fuel present in the fuel dispensing apparatus. The receiver determines whether the type of fuel required to be introduced into the fuel storage apparatus corresponds to the type of fuel present in the fuel dispensing apparatus. If the two types of fuel correspond, i.e., match, fuel is dispensed from the fuel dispensing apparatus into the fuel storage apparatus. If the two types of fuel do not match, the fuel dispensing apparatus is not activated. The receiving apparatus may also provide an indication that the fuel from the fuel dispensing apparatus does not match the type required to be introduced into the fuel storage apparatus. In another embodiment, if the two types of fuel do not match, a cut-off system is activated that stops dispensing of the fuel during the fueling process.
