Abstract
An internal combustion engine has a fuel supply device, wherein the fuel supply device includes a fuel pump, a fuel pressure damper, an injection valve, and a fuel pressure regulator. The fuel pressure damper has a damper membrane separating a damper chamber and a damper back chamber from each other. The damper chamber of the fuel pressure damper is loaded with a first reference pressure. The fuel pressure regulator regulates a pressure of fuel supplied by the fuel pump to the injection valve based on a second reference pressure of the fuel pressure regulator. The first reference pressure and the second reference pressure are adjusted relative to each other.
