CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine to control the combustion properly by making use of a crank angle at the time when a combustion mass ratio becomes a predetermined combustion mass ratio.SOLUTION: A combustion mass ratio (MFB) is calculated by making use of the internal data which is acquired by using a crank angle sensor 42 and an inner-cylinder pressure sensor 30. A crank angle (CA10) at the time when the MFB becomes 10% is acquired. A fuel injection rate is corrected to eliminate the difference between an actual SA-CA10 and a target SA-CA10 on a crank angle period from an ignition timing (SA) to CA10.
