Title:
INJECTION CONTROLLER OF CYLINDER INJECTION-TYPE INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP3680335
Kind Code:
B2
Abstract:
PURPOSE: To enable combustible mixture to be formed near a spark plug in the ignition timing by making the suitable dispersion time of spray injected during the compression stroke in an injection controller for a cylinder injection- type internal combustion engine.
CONSTITUTION: An injection controller is constituted of an injection amount calculating means provided with a fuel injection valve for directly injecting fuel into a cylinder of an engine, and for calculating the fuel injection amount to be injected from the fuel injection valve during the compression stroke, an injection completion timing calculating means for calculating the injection completion timing AINJ2 on the basis of the basic fuel injection amount required for one combustion cycle of the engine, and a fuel control means for controlling the fuel injection amount in the compression stroke so that fuel may be injected from the fuel injection valve only for the fuel injection time τ2 by taking the injection completion timing as the reference. The dispersing time of spray after injection is made appropriate by controlling fuel injection by taking the injection completion timing of the fuel as the reference, and combustible mixture suitable for ignition is formed near a spark plug in the ignition timing.
