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

The invention relates to a direct-injection spark-ignition internal combustion engine having at least one cylinder (1), in which - each cylinder (1) comprises a combustion chamber (2, 2a, 2b) which is defined by a piston head (5a) of a piston (5), a cylinder tube (5). 4) and the at least one cylinder head (3) is formed with, and - each cylinder (1) in the cylinder tube (4) is equipped with an injection device (6) which has at least two openings. It is intended to provide a spark-ignited internal combustion engine in which the mixture formation, in particular the homogenization of the fuel-air mixture, is improved. This is achieved with a spark-ignited internal combustion engine, which is characterized in that - the at least two openings form at least two groups, each with at least one opening, - the at least one opening of a first group is not aligned with the piston head (5a), whereas at least one Opening a second group on the piston head (5a) is aligned, and - the at least two groups each having at least one opening in the context of an injection process are activated offset in time, wherein the at least one opening of the first group earlier than the at least one opening of the second group is activated.
