Four-cycle engine with at least two intake valves per cylinder

摘要

The engine has at least two inlet valves per cylinder and a leakage flow path (16) for minimum throughput defined by flow guiding surfaces (18) near the channel dividing wall (10) between the two inlet channels (4,5) and at least between a choke (15) and a defined opening. The leakage flow path is essentially parallel to the second inlet channel, at least in some sections.
