Title:
CONTROL METHOD FOR IN-CYLINDER DIRECT-INJECTION INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2019/016862
Kind Code:
A1
Abstract:
In this control method for an in-cylinder direct-injection internal combustion engine, a tumble flow is formed within a cylinder, stratified injection is performed during a compression stroke such that fuel to be combusted around an ignition plug is injected from a fuel injection valve provided to a cylinder head on the inlet valve-side with respect to the central axis of the cylinder, and an air-fuel mixture formed with the fuel injected by the stratified injection is ignited by a spark from a spark plug. During the compression stroke, auxiliary injection is performed prior to the stratified injection from the fuel injection valve at a timing at which the centroidal line of an injected fuel spray passes the ceiling surface side of the combustion chamber in the cylinder axial direction from the vortex center of the tumble flow.
