Date May 4, 1995A method and a device for controlling the exhaust temperature for a combustion engine with knock control by varying the air/fuel mixture supplied to the engine as a function of ignition-retard settings to prevent knocking, as are undertaken by a knock-control device, an increasingly retarded ignition (setting) entailing increasing enrichment; the procedure is such that a cylinder-selective enrichment follows in dependence upon the momentary ignition-retard (setting) in a cylinder.
