A motor vehicle internal combustion engine has at least one combustion chamber delimited by at least one wall of the internal combustion engine, and at least one injector that is associated with the combustion chamber and that is at least partially accommodated in a receiving opening delimited by a first wall area of the wall extending at least essentially parallel to the axial direction of the injector The injector includes at least one injection opening that opens into the combustion chamber via the receiving opening, in the direction of the combustion chamber the first wall area being directly adjoined by a further wall area of the wall that extends at an angle to the axial direction and which delimits an at least essentially conical area of the receiving opening which expands toward the combustion chamber. Over its length relative to the radial direction of the injector, the further wall area is situated at a distance from the injector and in alignment with the injector, at least in places, and has a cone opening angle in a range of 50 degrees up to and including 90 degrees, the cone opening angle being smaller than a jet angle of the injection jet.

Internal combustion engine, in particular for a motor vehicle, and a method for operating such an internal combustion engine

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 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.
