Title:
ENGINE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/138279
Kind Code:
A1
Abstract:
Provided is an engine control device with which it is possible to minimize loss of combustion stability accompanying changes in engine temperature in an engine that performs lean combustion or EGR combustion. When lean combustion is performed to combust an air mixture leaner than the stoichiometric air/fuel ratio, or when exhaust recirculation combustion is performed to combust an air mixture that has been diluted by causing exhaust discharged from a combustion chamber 17 to be drawn back into the combustion chamber 17, the proportion of the fuel injection amount during the compression stroke relative to the total fuel injection amount during one combustion cycle is increased as the temperature of the engine 100 decreases.
