A fuel injector-spark plug combination includes a fuel injector for the direct injection of fuel into a combustion chamber of an internal combustion engine and a spark plug with a spark-plug insulator, the spark plug having a first electrode, and a second electrode for igniting the fuel injected into the combustion chamber. The fuel injector and the spark-plug insulator of the spark plug are arranged at a biaxial offset in a respective receiving bore of a shared connecting member inserted in a recess of a cylinder head.

Fuel injection valve spark plug combination

A fuel injector-spark plug combination comprises a fuel injector for the direct injection of fuel into a combustion chamber of an internal combustion engine and a spark plug with a spark-plug insulator, a first electrode and a second electrode for igniting the fuel injected into the combustion chamber. The fuel injector includes an actuator cooperating with an actuation device, which is in force-locking, operative connection to a valve needle, the valve needle, or a valve-closure member connected thereto, cooperating with a valve-seat surface to form a sealing seat. The valve needle of the fuel injector and the spark-plug insulator of the spark plug are positioned in a shared housing at a biaxial offset.

Combined fuel injection valve/ignition plug

A fuel injector-spark plug combination includes a fuel injector for the direct injection of fuel into a combustion chamber of an internal combustion engine, and a spark plug for igniting the fuel injected into the combustion chamber, and has a spark-plug insulator including a first electrode, and includes a second electrode. The fuel injector and the spark-plug insulator of the spark plug are each disposed in a recess of a cylinder head of the internal combustion engine. The fuel injector and the spark-plug insulator of the spark plug are fixedly held in place in a shared connecting member arranged outside of the cylinder head.

Fuel injector-spark plug combination

The invention relates to a fuel injection apparatus for an internal combustion engine, having an injection valve that protrudes into the combustion chamber of the engine. This valve communicates with a valve chamber in that a control part closes and opens inlet bores for fuel that is at high pressure. The control part is actuatable by means of a hydraulic-mechanical booster. The pump part, valve part and nozzle part of the fuel injection apparatus are disposed in a vertical arrangement, hydraulically in line with on another in terms of the fuel flow.

The invention relates to a method for injecting fuel, which is at high pressure, into air-compressing internal combustion engines employing an injection system which includes a compressor unit for compressing fuel and containing an actuating device for control valves with which device the nozzle needle of an injector is controlled. One of the two control valves is triggered multiple times or in clocked fashion via a piezoelectric actuator during individual injection phases or during the injection cycle.
