Claims

[Scope of utility model registration request]

In a swirl generating device that generates swirl when supplying intake air to a combustion chamber of an engine, a groove is provided between an intake valve and an exhaust valve of a cylinder head forming the combustion chamber, and a groove is provided in the groove at low speeds of the engine. A vertical swirl generating device for an engine combustion chamber, characterized in that a baffle plate is provided that protrudes into the combustion chamber only occasionally to generate a vertical swirl by intake air.
