  • Fuel system for an internal combustion engine
    Patent number: 9422897
    Abstract: In a fuel system of an internal combustion engine, a low-pressure delivery unit for the fuel, at least indirectly delivers fuel to at least one low-pressure injection device. The fuel system further provides a high-pressure delivery unit, which has a drive region and a delivery region and at least indirectly delivers fuel to at least one high-pressure injection device. According to the invention, the fuel is first delivered by the low-pressure delivery unit to the drive region of the high-pressure delivery unit and from there onward to the low-pressure injection device and/or to the delivery region of the high-pressure delivery unit.

  • Fuel feed device and method for producing a fuel feed device
    Patent number: 9038600
    Abstract: A fuel feed device for attachment to a cylinder head of an internal combustion engine has at least one fuel distribution element extending along a longitudinal direction, and at least one connecting element extending transversely to the longitudinal direction, wherein the connecting element can be used to connect the fuel distribution element to the cylinder head. The fuel feed device further includes at least one reinforcing element which is connected, on one hand, to an outer surface of the fuel distribution element and, on the other hand, to the connecting element outside the fuel distribution element.
