Abstract
The invention relates to an invention combustion engine comprising a cylinder head (1) with at least one inlet port (4) and at least one injection device (6) per cylinder (2), which extends into the combustion chamber. In order to reduce wear of the injection device while preventing depositions in the region of the injector pocket, the top wall (22) of the combustion chamber is provided with an injector pocket (7) in the area of the mouth (6a) of the injection device (6). Preferably, at least one scavenging duct arrangement (10) extends into the injector pocket (7).
