摘要： A ceramic sheathed-type glow plug, whose ceramic heating element is made of an electrically conductive conducting layer and an electrically insulating layer, is described. The conducting layer is made of lead layers and a heating layer. The higher specific electrical resistance of the heating layer allows the temperature of the heating layer and the combustion chamber to be determined. The electrical contact between a connector element and the heating element is established by a contacting element, which is in the form of a pellet made of an electrically conductive powder.

摘要： A fuel injection system has a pressure step-up unit, disposed between a pressure storage chamber and a nozzle chamber, whose pressure chamber communicates with the nozzle chamber via a pressure line. A bypass line connected to the pressure storage chamber is also provided. The bypass line communicates directly with the pressure line. The bypass line can be used for pressure injection and is disposed parallel to the pressure chamber, so that the bypass line is open regardless of the motion and position of a displaceable piston element in the pressure step-up unit. This enhances the flexibility of injection.

摘要： A fuel injection is effected by means of a high-pressure pump (2) and a pressure reservoir chamber (6) for generating and storing a first system pressure. This system pressure is not used for injection; instead, by means of the pressure booster unit (9), a higher injection pressure is generated during the injection, and this injection pressure can be reduced to shape the course of injection. By means of this invention, an improved capability of metering the fuel injection and an improved execution of fast switching times are achieved.

摘要： A method and system for injecting fuel in at least two different high fuel pressures via injectors into a combustion chamber of an internal combustion engine. The higher fuel pressure being stored in a central pressure reservoir, the lower fuel pressure is generated individually locally for each injector, at all times during the injection event by diversion of the higher fuel pressure. The diversion being activatable or deactivatable via a multi-way valve. To that end, a corresponding fuel injection system with a central pressure reservoir for storing the higher fuel pressure has a local diversion unit for each injector by means of which the lower fuel pressure can be generated dissipatively from the higher fuel pressure, and the local diversion unit has a multi-way valve for activating and deactivating the diversion, respectively. In this way, an improved metering of the lower fuel pressure can be achieved.
