Claims

[Scope of utility model registration request]

an air injection pipe that opens into an intake port and injects air toward a combustion chamber when the intake valve is open; an air pump; and an air pump that opens and closes in response to the opening and closing of the intake valve when the intake valve is open. A swirl generating device for an engine, comprising: a valve device for supplying air from the air pump to the air injection pipe.
