Abstract
A fuel control system for controlling the purging of alternate fuel in an internal combustion engine at shutdown includes: at least one valve device configured to deliver a fuel supply to the engine; a first fuel source configured to provide a primary fuel to the valve device; a second fuel source configured to provide an alternate fuel to the valve device; and a controller connected to the valve device and adapted to be connected to an ignition system. The controller is configured to control the valve device responsive to a status of one of the engine and the ignition system.
Claims19
A fuel control system for controlling the purging of alternate fuel in an internal combustion engine at shutdown, comprising:
- at least one valve device configured to deliver a fuel supply to the engine;
- a first fuel source configured to provide a primary fuel to the valve device;
- a second fuel source configured to provide an alternate fuel to the valve device;
- and
- a controller connected to the valve device and adapted to be connected to an ignition system, the controller being configured to control the valve device responsive to a status of one of the engine and the ignition system.
5-6. (canceled)
An internal combustion engine assembly capable of operating on primary and alternate fuels, comprising:
- an internal combustion engine;
- a first fuel source connected to the engine;
- a second fuel source connected to the engine;
- a fuel control unit connected with the first and second fuel sources for regulating fuel to the engine;
- an ignition system;
- and
- a controller connected to the engine, the fuel control unit and the ignition system, the controller being configured to control the fuel control unit responsive to a status of one of the engine and the ignition system.
13-14. (canceled)
A method of controlling the purging of alternate fuel in an internal combustion engine at shutdown, comprising:
- signaling an internal combustion engine to cease operation, the signaling being carried out with an ignition system;
- detecting a status of one of the ignition system and the internal combustion engine;
- and
- overriding the signal from the ignition system responsive to the detected status such that the engine continues to operate in order to purge alternate fuel.
