Title: Air-fuel ratio control system by cylinder for internal combustion engine
Inventor: KITA MASAYUKI
IPC: F02D41/36
Filed: 2004-08-31
Abstract: <P>PROBLEM TO BE SOLVED: To accurately detect a lag of sampling timing (air-fuel ratio detecting timing by cylinder) of output from an air-fuel ratio sensor during operation of an internal combustion engine, in regard to a system for estimating air-fuel ratio by cylinder on the basis of a detection value of one air-fuel ratio sensor provided in an exhaust collecting part.  <P>SOLUTION: Air-fuel ratio of each of the cylinders is estimated on the basis of a detection value of the air-fuel ratio sensor 37 provided in the exhaust collecting part 36, and air-fuel ratio of each of the cylinders is controlled on the basis of the estimated air-fuel ratio of each of the cylinders. During the air-fuel ratio control by cylinder, existence of a lag of air-fuel ratio detecting timing is determined on the basis of degree of unevenness of the estimated air-fuel ratio between the cylinders. In the case wherein a lag of the air-fuel ratio detecting timing is detected, air-fuel ratio detecting timing of each of the cylinders is changed to estimate air-fuel ratio before and after correcting the fuel of each of the cylinders with the corresponding air-fuel ratio detecting timing, and the air-fuel ratio detecting timing when variable quantity of the estimated air-fuel ratio before and after correcting the fuel corresponds to the fuel correction quantity is learned as the appropriate air-fuel ratio detecting timing.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
