Control apparatus for internal combustion engine

摘要

A control apparatus for an internal combustion engine handles a plurality of engine control parameters which influence the emission generation quantity, while dividing them into a plurality of classes in terms of response speed. An empirical formula which obtains the emission generation quantity by use of the plurality of parameters as arguments is solved for each parameter, whereby an equation for obtaining the value of a parameter of a class of interest while using parameters of the remaining classes and the emission generation quantity as arguments is obtained for each parameter. In each of the obtained equations, a target value is used as an argument value of the emission generation quantity, an actual value is used as an argument value of a parameter of a class which is lower in response speed than the class of interest, and a steady-state adequate values is used as an argument value of a parameter of a class which is higher in response speed than the class of interest. The values calculated by these equations are used as target values of the parameters.
