摘要： An ignition circuit for a combustion engine has an ignition coil and a control unit for the coil. The coil and the control unit are included in a common component as an ignition module. The module is supplied with voltage by a generator driven by the engine. A spark plug and the coil form a power circuit which includes a line segment to a reference potential outside the module. A sensor detects data of the engine and the output of the sensor is supplied to the module. The sensor is supplied with voltage via a sensor circuit. The sensor circuit and the power circuit use the line segment as a common connection to the reference potential, so that for a defect of the line segment, a missing connection to the reference potential in the high voltage circuit is recognized via the change of the sensor output signals.

摘要： 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.
