Abstract: PURPOSE: An adaption method for controlling the injection is provided to inject a same amount of a fuel at all of cylinder by compensating a change of an injection valve based on a phase-wise stoichiometric operation and lean operation. CONSTITUTION: In an adaption method for controlling an injection of a multi- cylinder internal-combustion engine, which is operated phase-wise stoichiometric and lean, the injection for each cylinder is controlled continuously in stoichiometric and homogeneous-lean operating phases, so that each cylinder on average is operated with stoichiometric or the required homogeneous-lean mixture, where a first correction factor is continuously determined and stored, for the basic injection values(S4), and which restores or reproduces the deviation of the actual injection from the desired injection(S5). In the stratified-lean operating phases, a control of injection for each cylinder is carried out so that each cylinder generates a given torque or that the running smoothness of the engine is maximal(S10). A correction of the basic injection values then follows, during which the first correction factor stored finally in the stoichiometric operating phase is used.
