INTAKE PORT STRUCTURE FOR INTERNAL COMBUSTION ENGINE |
摘要 |
An intake port structure for an internal combustion engine according to the invention includes a valve shaft provided in an intake port; and an airflow control valve that is supported by the valve shaft at one end of the airflow control valve or at a position near the one end. A gap is formed between the airflow control valve and a wall surface of the intake port, which is positioned on one side of the valve shaft. Because intake airflow passes through the gap that is formed, the generation of a deposit is suppressed, and the locking of the airflow control valve is avoided. |
