Internal combustion engine, has bypass channel with flow axis arranged with respect to cylinder in region of intersection in inlet channel, where ratio of distance of flow axis of bypass channel to radius of cylinder amounts to preset value

摘要

The engine has an inlet channel (3) extending into a cylinder (2) through an inlet opening (7), and an inlet valve arranged in the region of the inlet opening. A bypass channel branches from the inlet channel upstream of a flow control unit and extends downstream of the control unit, where a flow axis (6`) of the bypass channel is arranged tangentially with respect to the cylinder in a region of intersection (10) in the inlet channel. A ratio of a normal distance (R) of the flow axis of the bypass channel with respect to a cylinder axis, to radius of the cylinder amounts to 0.6 to 0.9. Independent claims are also included for the following: (1) a method for operating internal combustion engine (2) an exhaust gas system with a catalytic converter.
