Abstract
A pump component is removed from a port of a suction-side fluid cavity of a high-pressure fluid pump. The pump component performs a pump function for the high-pressure fluid pump. A primary coupler connects to the port. The pump component connects to the primary coupler. A diverter fluid passage diverts a low-pressure fluid from the primary coupler to an auxiliary fluid delivery system. The primary coupler communicates the low-pressure fluid through the pump component and primary coupler to the port.
Claims21
1-25. (canceled)
An internal combustion engine system, comprising:
- an internal combustion engine;
- a primary fuel supply system structured to supply a fuel flow to said internal combustion engine for generating mechanical power with said internal combustion engine;
- an emission control system coupled to an exhaust of said internal combustion engine;
- and
- an auxiliary fuel delivery system fluidly disposed between said primary fuel supply system and said emission control system, said auxiliary fuel delivery system structured to receive a continuous flow of a fuel from said primary fuel supply system and provide an intermittent flow of the fuel to said emission control system.
An emission control system for an internal combustion engine, comprising:
- a catalytic converter in fluid communication with an exhaust of said internal combustion engine;
- an auxiliary fuel delivery system in fluid communication with said catalytic converter and fluidly coupled to a primary fuel supply system of the internal combustion engine, said auxiliary fuel delivery system is structured to receive a continuous flow of fuel from said primary fuel supply system and to provide an intermittent flow of fuel to regenerate said catalytic converter.
An internal combustion engine system, comprising:
- an internal combustion engine;
- a primary fuel supply system structured to supply a fuel flow to said internal combustion engine for generating mechanical power with said internal combustion engine;
- a catalytic converter coupled to an exhaust of said internal combustion engine;
- coupled to said primary fuel system, means for receiving a continuous flow of a fuel from said primary fuel supply system;
- and
- coupled between said means for receiving and said catalytic converter, means for providing an intermittent flow of said fuel to said catalytic converter.
A system for regenerating an emission control system, comprising:
- a pumpless auxiliary fluid delivery system adapted to be fluidly coupled to a primary fuel supply system of an internal combustion engine, said pumpless auxiliary fluid delivery system structured to receive a continuous flow of a fuel from said primary fuel supply system and to provide an intermittent flow of the fuel to an emission control system fluidly coupled to an exhaust of said internal combustion engine, wherein an operating pressure of said pumpless auxiliary fluid delivery system is supplied by said primary fuel supply system.
