20130146028 | Internal combustion engine with fuel supply device - 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. | 06-13-2013 |
20130340693 | Power Tool - A power tool has an internal combustion engine with a cylinder. An injection valve supplies fuel to the internal combustion engine. A fuel pump conveys fuel from a fuel tank to the injection valve. A fan wheel is provided that is driven by the internal combustion engine. The cylinder is arranged in a first cooling zone of the power tool and the fan wheel conveys cooling air through the first cooling zone. The fuel pump is arranged in a second cooling zone of the power tool. Between the first cooling zone and the second cooling zone a buffer zone is arranged.
