Document Type and Number:
Japanese Patent JP2002522686
Kind Code:
A
Abstract:
The invention relates to a four stroke internal combustion engine with applied ignition, wherein fuel is directly injected into a combustion chamber by means of an injector. Said engine comprises at least one admission channel with an admission valve and at least one exhaust channel with an exhaust valve, the admission valve and the exhaust valve being placed on opposite sides of the combustion chamber and the injector being placed on the admission valve side. Said engine also comprises a cavity formed in a piston top. A piston exhibits a central longitudinal axis extending in the direction of displacement of said piston. The cavity is placed on the admission valve side and exhibits, relatively to said admission valve and the injector, a marginal area forming the highest point of the piston top so that an airflow originating in the appropriately designed admission channel and penetrating into the combustion chamber through the admission valve and an injection jet originating in the injector and penetrating into the combustion chamber enter the cavity at opposite points.
