A method for compensating for mismatches of the precontrol of a fuel metering for an internal combustion engine. A regulation being superimposed on the precontrol. At least one correction quantity being formed, from the behavior of the regulation at high temperatures of the internal combustion engine, which influences the fuel metering even at low temperatures of the internal combustion engine in a supplementing manner to the superimposed regulation for compensating for the mismatches. At low temperatures a further correction quantity is formed which acts upon the fuel metering, whose effect at low temperatures of the internal combustion engine is greater than at high temperatures.

Mixture adaptation method

A device for controlling an internal combustion engine having an arrangement for recording operating parameters of the internal combustion engine, such as engine speed, load, and coolant temperature; an arrangement for providing a signal related to a desired drive torque of the internal combustion engine (engine torque) as a function of the recorded performance quantities; and an arrangement for converting the engine torque into control signals for at least one of the variables air supply or fuel supply to the internal combustion engine, as a function of the coolant temperature toot and of a pre definable maximum allowable coolant temperature limit tom-tom, a torque control value being determined which ultimately determines the allowable engine torque.

Method of controlling ignition in a multicylinder internal combustion

The invention relates to a learning control method for adjusting the composition of an operating mixture for an internal combustion engine. The method includes the steps of: detecting the actual value of the composition; forming a control variable as a function of the instantaneous deviation of the actual value from the desired value; logically coupling the control variable to a base value of an adjusting parameter of the composition and driving an actuator on the basis of the logically coupled value; and, learning of an additional intervention in the control loop from the performance of the control loop wherein the learning takes place at a speed which is at least dependent upon temperature.
