Abstract:
1. 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; 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; and wherein said primary fuel supply system is structured to supply the fuel flow to said internal combustion engine within flow rate and pressure ranges, and wherein said auxiliary fuel delivery system is adapted to prevent the fuel flow to said internal combustion engine from dropping below said flow rate and pressure ranges.
