Abstract
An intake system for an internal combustion engine has at least one inlet channel through which air can flow and by which the air flowing through the inlet channel is to be conducted into at least one combustion chamber of the internal combustion engine. The inlet channel is, on the bottom side thereof, of flat form at least in one length region, wherein the flat bottom side extends as far as a tumble edge by which a tumbling flow of the air flowing into the combustion chamber can be effected.
Claims11
An intake system for an internal combustion engine, comprising:
- at least one inlet duct through which air flows and by which the air which flows through the inlet duct is conducted into at least one combustion chamber of the internal combustion engine, wherein
- the inlet duct has a flat underside at least in one length region on the underside,
- the flat underside is located in a region where the at least one inlet duct branches and extends as far as a tumble edge, by which a cylindrical tumble-shaped flow of the air which flows into the combustion chamber is effected,
- the cylindrical tumble-shaped flow tumbles about a tumble axis which runs perpendicularly with respect to a cylinder axis, and
- the tumble edge is immediately adjacent to a valve seat ring that is defined at an outflow opening of the intake system.
