Abstract

The engine has an intake channel (3), an intake valve (2), and a rotary slide (4) upstream of the valve. A front control edge section (6) of an intake aperture (5) defines a recess (8), located leading in rotary direction (A) of the slide, to generate a compact charging jet. Intake aperture and recess of the slide form an asymmetrical cross section. The recess is part of the corner (9) of the intake channel. The intake aperture is triangular, with long side parallel to the slide axis.
