Internal combustion engine, especially for motor vehicles, with utilisation of the exhaust gas pressure to improve the cylinder charging

摘要

Simple designs for the rotary slide valve (107) for achieving the boost effect according to the main patent ... contain as their basic elements, two transverse walls (100, 101), offset in relation to one another in the direction of the axis of the rotary slide valve (107), with recesses (103, 104) open in the direction of the middle area of the rotary slide valve (107) and towards a point on the circumference (105, 106), which, during boosting, tightly seal off from the exhaust gas system the middle area of the rotary slide valve (107) located between them, in which are located entry points of the inlet lines (E1, E2) and connection points of the intake system (AS), but, for scavenging of the middle rotary slide valve area, each make a connection with one of the exhaust gas lines (SK1', SK2') of the exhaust gas system.
