Air-fuel mixture adaptation method for internal combustion engine with gasoline direct injection device

摘要

A method for compensating for faulty adaptations of the pilot control of fuel metering for an internal combustion engine which is operated in the at least two different operating modes, homogeneous mode and stratified charge mode, is described withmixture regulation and adaptation of mixture regulation taking place in homogeneous mode, andswitching taking place between the operating modes, depending on a desired operating mode which is determined from a plurality of operating mode requirements, each of the operating mode requirements being assigned a priority, andthe desired operating mode being determined depending on the priorities of the operating mode requirements,the physical priority of the adaptation being elevated in different time references, thus requiring a switch to homogeneous mode
