An ignition system for an internal combustion engine, having a combustion chamber and a fuel injection device which injects a fuel directly into the combustion chamber in stream-guided fashion, is configured so that the ignition system has a positive polarity.

Ignition system for an internal combustion engine

The invention relates to a method for operating a combustion engine () comprising a fuel-driven heat engine (), which permits a differentiation of faults during the supply of fuel. To this end, the fuel is supplied under pressure to the heat engine () via a fuel supply (). A pressure reduction speed in the fuel supply () is determined, and a fault is inferred based on a comparison of the pressure reduction speed with a predetermined threshold value.

Method for determining a fuel pressure related fault and operating an internal combustion engine based on the fault

A sealing element for a fuel injector insertable into a receiving bore of a cylinder head of an internal combustion engine for direct injection of fuel into a combustion chamber of the internal combustion engine includes a sealing element surrounding a nozzle body of the fuel injector peripherally. The sealing element includes a base body having an axial recess through which the nozzle body extends. The base body also has an annular recess which communicates with the recess and into which the sealing element is introduced. At a first contact face, the base body is in at least indirect contact with an end face of the fuel injector, and at a second contact face opposite the first contact face, the base body is at least in indirect contact with a step of the receiving bore.

Sealing element and holding-down clamp for a fuel injector

In a method for operating an internal combustion engine of a motor vehicle, in particular, pressurized fuel is conveyed to a fuel accumulator. The fuel is injected into a combustion chamber via a fuel injector. Coking of the fuel injector is determined. A first fuel-pressure increase is implemented when the coking exceeds a threshold value.

An alignment element for securing a fuel injector, for the direct injection of fuel into the combustion chamber of an internal combustion engine, to a cylinder head of the internal combustion engine in a manner to ensure locking against rotation includes a ring that is slipped onto the fuel injector, provided on the ring is at least one plug that is arranged on the ring, slipped onto the fuel injector, in such a manner that it is able to snap into a recess in a plastic coating of the fuel injector.

A sealing element ( ) for a fuel injector ( ) insertable into a receiving bore ( ) of a cylinder head ( ) of an internal combustion engine for direct injection of fuel into a combustion chamber ( ) of the internal combustion engine has a sealing element ( ) surrounding a nozzle body ( ) of the fuel injector ( ) peripherally. The sealing element ( ) includes a base body ( ) having an axial recess ( ) through which the nozzle body ( ) extends. The base body ( ) also has an annular recess ( ) which communicates with the recess ( ) and into which the sealing element ( ) is introduced. At a first contact face ( ), the base body ( ) is in at least indirect contact with an end face ( ) of the fuel injector ( ), and at a second contact face ( ) opposite the first contact face ( ), the base body ( ) is at least in indirect contact with the step ( ) of the receiving bore ( ).

A fuel injection valve has an attachment with a two-part design including a main body and an insert. With the attachment, the functions of supplying and metering gas are optimized independently of the functions of sealing off the fuel injection valve with respect to an intake conduit and of securing the attachment onto the fuel injection valve. In addition, the fuel injection valve and attachment provide a modular system which allows a large number of possible variations which can be achieved by simple and inexpensive component changes.
