US 8,006,677 B2 · Fuel control system and associated method

Abstract

A fuel control system and method for providing fuel to an internal combustion engine are provided. The fuel control system generally includes at least one valve device structured to deliver a fuel supply to the engine, a first fuel source structured to provide a primary fuel to the valve device, a second fuel source structured to provide an alternate fuel to the valve device, and an electronic controller structured to control the valve device. The electronic controller controls the valve device as a function of various data to selectively deliver the primary fuel and the alternate fuel to generate a fuel supply, e.g. as a mixture of the two fuels. The data used to control the fuel supply may include GPS data, engine data, environmental data, and/or other operational data.

Dependent claims

A fuel control system, comprising:

at least one valve device configured to direct fuel to an engine of a vehicle;
a first fuel source configured to provide a primary fuel to the at least one valve device;
a second fuel source configured to provide an alternate fuel to the at least one valve device;
and
an electronic controller configured to control the at least one valve device to selectively direct the primary fuel and/or the alternate fuel to the engine;
wherein the electronic controller is further configured to control the at least one valve device to exclusively direct the primary fuel to the engine for a period of time to purge the engine prior to the engine being stopped based on one or more of altitude, grade, throttle, and transmission status of the vehicle.
