Abstract (en)
[origin: EP1134607A2] An object system is regarded as being equivalent to a system for generating an output of an O2 sensor (12) or exhaust gas sensor from a target combined air-fuel ratio that is produced by combining target air-fuel ratios KCMD for respective cylinder groups (3, 4) according to a filtering process of the mixed model type. With the equivalent system as an object to be controlled, an air-fuel ratio processing controller (15) determines a target combined air-fuel ratio, and determines a target air-fuel ratio KCMD for each of the cylinder groups (3, 4) from the target combined air-fuel ratio. The air-fuel ratios in the cylinder groups (3, 4) are manipulated into the target air-fuel ratio according to a feed-forward control process. <IMAGE>
