Abstract
A method and an apparatus are proposed for adapting the exhaust gas recirculation rate in internal combustion engines, in particular Diesel engines. In order to prevent the smoke which is produced at first in new engines, or when injection nozzles or the like are replaced, an adjustment is made in the exhaust gas recirculation rate, acting as a supplement to the change in this rate which is conventionally made, the supplementary adjustment being preferably performed in stages and with reference to the function of the duration of operation from the time the varying operating conditions begin. The number of injection events is counted and successive memory locations are triggered at time intervals, effecting an adaptation of the exhaust gas recirculation rate up to the final status, each stage in adaptation being stored permanently in memory as it is attained.
