Title:
【発明の名称】二次給気流発生手段を備えたピストン式内燃機関
Document Type and Number:
Japanese Patent JP2003502550
Kind Code:
A
Abstract:
The invention relates to a piston-type internal combustion engine in which fuel is injected into the combustion chamber (2). Said combustion chamber is formed in the cylinder (1) and is delimited by a combustion chamber top (3) provided with at least one gas exhaust valve (9) and at least one gas intake valve (7), as well as by a piston (10) provided with a piston recess (11) and a quench area (12). According to the invention, at least the gas intake (4) is configured in the combustion chamber top (3) in such a way that the inflowing air creates a tumbling flow in the combustion chamber (2), and whereby the piston (10), in the vicinity of its quench area (12) provided for the downwardly directed air flow, has at least one guide element (16; 18) which runs in an approximately helicoidal manner from the outer edge of the piston toward the piston recess (11).
