Title:
直接噴射式火花点火内燃機関のために給気成層を用いる燃焼方法
Document Type and Number:
Japanese Patent JP2005511945
Kind Code:
A
Abstract:
In an internal combustion engine having direct injection and spark ignition, charging air is introduced in stratified charge operation through one of two valve-controlled intake channels into a cylinder having a roof-like cylinder head end and a piston having a piston head with a recess oriented toward the intake side. The charging air is introduced forms a swirl flow, into which fuel is introduced. To avoid fuel accumulation on the recess wall, a strong swirl flow with a compact swirl core is achieved through a flow-optimized filling channel, with the swirl core being held in a fixed position in a rotor recess at the latest in the second section of the stroke of the piston toward top dead center such that fuel introduced into the swirl core with a relatively late end of the injection is supplied to an ignition device due to the piston movement toward top dead center.
