Title:
INTERNAL COMBUSTION ENGINE CONTROL DEVICE AND METHD
Document Type and Number:
WIPO Patent Application WO/2006/054794
Kind Code:
A1
Abstract:
The ECU (20) of an internal combustion engine (1) estimates the quantity of air corresponding to the demand on the internal combustion engine (1), controls an injector (12) to inject an initial injection quantity of fuel determined such that the air/fuel ratio of the mixture in a combustion chamber (3) is a target level or less depending on the estimated quantity of air, calculates the quantity of air sucked into the combustion chamber (3) from the cylinder pressure in the combustion chamber (3) at a predetermined timing during the compression stroke before the ignition, and controls the injector (12) to inject a corrected injection quantity of fuel determined according to the calculated quantity of sucked air and the initial injection quantity such that the air/fuel ratio of the mixture in the combustion chamber (3) agrees with a target air/fuel ratio.
