Title:
ガソリン直噴装置を備えた内燃機関における混合気適合方法
Document Type and Number:
Japanese Patent JP2004507656
Kind Code:
A
Abstract:
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. The method includes mixture regulation and adaptation of mixture regulation occurring in homogeneous mode; switching occurring between the operating modes, depending on a desired operating mode which is determined from a plurality of operating mode requirements. Furthermore, each of the operating mode requirements is assigned a priority; and the desired operating mode is determined depending on the priorities of the operating mode requirements. Also, switching to homogeneous mode with the activation of the adaptation momentarily occurs, even outside the normal starting conditions of the adaptation. A deviation of the adaptation quantity from its neutral value during the short-time activation is evaluated as a suspected error, with the engine control program elevating the priority of the adaptation under normal starting conditions when a suspected error is present.
