ABSTRACT:
A fuel delivery system for a combustion engine is provided. The fuel delivery system includes an exhaust treatment device, a fuel injection unit, a fuel supply, and a fuel pump. The fuel pump includes at least one inlet configured to receive fuel from the fuel supply. A first fixed-output pumping element is configured to generate a first fuel flow at a first pressure and a first flow rate. A second fixed-output pumping element is configured to generate a second fuel flow at a second pressure and a second flow rate. At least one of the second pressure and the second flow rate is different from the first pressure and the first flow rate. A first outlet is configured to direct the first fuel flow to the fuel injection unit. A second outlet is configured to direct the second fuel flow to the exhaust treatment device.
