Abstract:
A secondary fueling system for a diesel internal combustion engine includes an injector which injects an oxygen-containing secondary fuel into the engine's air intake system, a pump which pumps the secondary fuel to the injector, a sensor which senses pressure in the air intake system, and a secondary fuel controller which receives output signals from the sensor and pump, operator inputs for the engine, and data signals pertaining to operation of the engine from the main engine controller, determines an injection amount of the secondary fuel based thereon, and controls the pump based on the determined injection amount. The secondary controller may operate an additional control wherein the injection amount of secondary fuel determined by the programmed secondary fuel controller is modified based on at least one of topology conditions of roads on which the vehicle is traveling and considerations of efficient engine output in comparison to driver requests for engine output.

Claim (Index 1):
A secondary fueling system for a diesel internal combustion engine having a system for directly injecting diesel fuel into cylinders of the engine, an air intake system through which air is drawn into the engine cylinders, and a main engine controller, the secondary fueling system comprising:\n an injector which injects an oxygen-containing secondary fuel into the air intake system; a pump which pumps the secondary fuel to the injector; a sensor which senses pressure in the air intake system; and a programmed secondary fuel controller which receives output signals from the sensor and pump, receives operator inputs for the engine, and receives data signals pertaining to operation of the engine from the main engine controller, determines an injection amount of the secondary fuel based thereon, and controls the pump based on the determined injection amount, wherein a position of the injector in the engine's air intake system is distant from the engine's intake valves and is based on the engine's displacement, and wherein the diesel internal combustion engine is provided as a power plant for a vehicle and the injection amount of secondary fuel determined by the programmed secondary fuel controller is modified based on at least one of topology conditions of roads on which the vehicle is traveling and considerations of efficient engine output in comparison to driver requests for engine output.
