A cylinder head for an internal combustion engine includes a spark plug , provided in combustion chamber , and an injection nozzle that has a housing end face and a closure element which is movable by an actuator and has a closure member , the housing end face of the injection nozzle forming a common, planar surface with the closure member in the closed state of the injection nozzle

Injection nozzle and a method for forming a fuel-air mixture

A method for the formation of a combustible fuel/air mixture in a combustion chamber of a direct-injection internal combustion engine with an injection nozzle, which has a closure body includes the steps of injecting at least two partial quantities of fuel into the combustion chamber and moving the closure body of the injection nozzle into its closed position after the injection of each of the partial quantities of fuel.

Method for the formation of a combustible fuel/air mixture

In a gasoline internal combustion engine with direct fuel injection a spark plug with a center electrode is mounted in the cylinder top so as to project into the combustion chamber. A mass electrode is disposed on the piston so as to project upwardly into the combustion chamber and is movable with the piston toward and from the spark plug center electrode. An ignition system is provided for timely generating a spark between the spark plug electrode and the movable mass electrode for igniting a fuel/air mixture in the combustion chamber. A fuel injector is mounted in the cylinder top and adapted to provide a cone-like fuel beam with an envelope disposed between the spark plug electrode and the mass electrode such that a spark generated between the two electrodes extends through the fuel injection beam envelope.

Gasoline internal combustion engine

In an internal combustion engine with direct fuel injection having a piston disposed in a cylinder and a cylinder head which together define a combustion chamber, wherein a fuel injector is mounted in the cylinder head so as to inject fuel into the combustion chamber in a conical pattern whereby the fuel is mixed with combustion air to form a combustible mixture, the cylinder head has a shape around the conical fuel pattern which aids in providing combustible fuel/air mixture at least in an area adjacent the conical fuel pattern where a spark plug with electrodes is mounted such that its electrodes are disposed outside the conical fuel pattern.
