Direct-injection spark-ignition internal combustion engine with injection device arranged in the cylinder tube and method for operating such an internal combustion engine

摘要

Direct injection spark-ignited internal combustion engine having at least one cylinder (1), in which - each cylinder (1) has at least one inlet opening (7) for supplying combustion air via the intake system and at least one outlet opening (8) for discharging the exhaust gases via the exhaust removal system, - 1) comprises a combustion chamber (2) formed by a cylinder tube (4) laterally delimiting the combustion chamber (2), and - each cylinder (1) in an area of the cylinder tube (4) with an injection device (6) for direct injection Introducing fuel into the combustion chamber (2) is equipped, which has at least one opening which is activated in the context of an injection process for the purpose of introducing fuel into the combustion chamber (2), characterized in that - each cylinder (1) with an additional injection device (9) which is arranged in the cylinder-associated cylinder head (3), wherein the injection device (6) is aligned with the additional injection device (9) such that a virtual extension (6c) of a longitudinal axis (6c) of the injection device (6) with a virtual extension (9c) of a longitudinal axis (9c) of the additional injection device (9c) 9) in a projection perpendicular to the piston longitudinal axis (5b) forms an obtuse angle α.
