Abstract: A method of controlling the air fuel ratio in internal combustion, engines, comprising the steps of: 
updating first learning terms at a first learning speed in response to a signal from the air-­fuel-ratio sensor and respectively storing them in a reloadable memory device, the first learning terms being provided for respective different ranges correspond­ing to different engine temperature and related to factors causing variation in air-fuel ratio in such a manner that the air-fuel-ratio variate of the variation varies depending upon the engine temperature; 
updating second learning terms at a second learning speed which is higher than the first learning speed in response to a signal from the air-fuel-ratio sensor and storing them in the reloadable memory device, the second learning terms being related to factors causing variation in air-fuel ratio in such a manner that the air-fuel-ratio variate of the variation varies in a substantially uniform manner with respect to the engine temperature; and 
determining the transient learning value on the basis of the first learning terms dependent on the engine temperature and stored in the memory device and of the second learning terms stored in the memory device, and correcting the transient correction value in accordance with the transient learning value thus determined.

Abstract: In a combustion plant, which is operated with fossil fuels, the waste gases (A) from the combustion chamber (22) are cooled in a heat exchanger (X). A portion of these cooled waste gases (A') is mixed with fresh air (L) and conducted via a blower (D) in the direction of the burner (Z). This waste gas/fresh air mixture forms the combustion air (15) for the burner (Z). Before this combustion air (15) is introduced into the burner (Z), it is heated again in the heat exchanger (X'). The combustion air (15) thus preheated guarantees complete evaporation of a liquid fuel (12) and counteracts the high flame temperature peaks in the combustion chamber (22), directly after the burner (Z), which are responsible for the formation of nitrogen oxide. The burner (Z) can be operated with liquid and/or gaseous fuel.
