| 发明名称 | Intake system of internal combustion engine | ||
| 摘要 | The present invention provides an intake system of an internal combustion engine. A plasma actuator is provided in a region which is on an inner wall surface of an intake passage and to which fuel injected from a fuel injection valve adheres. The plasma actuator is disposed so as to generate an airflow in a predetermined direction not including a component in a direction toward a downstream side of the intake passage at the time of its operation. A control unit is configured to control the plasma actuator so as to actuate the plasma actuator in at least a part of a period from start of fuel injection by the fuel injection valve to start of valve opening of an intake valve. | ||

| 主权项 | 1. An intake system of an internal combustion engine comprising: a fuel injection valve that injects fuel to an intake passage; a plasma actuator provided in a region which is on an inner wall surface of the intake passage and to which the fuel injected from the fuel injection valve adheres; and a control unit configured to control the plasma actuator, wherein the plasma actuator is disposed so as to generate an airflow in a predetermined direction not including a component in a direction toward a downstream side of the intake passage at the time of its operation, and wherein the control unit controls the plasma actuator so as to actuate the plasma actuator in at least a part of a period from start of fuel injection by the fuel injection valve to start of valve opening of an intake valve. | ||
