  • Method and arrangement for controlling an internal combustion engine
    Patent number: 5623905
    Abstract: The invention is directed to a method and an arrangement for controlling an internal combustion engine. An electronic adjustment of a power adjusting unit for influencing the supply of air is provided. The adjustment of this power adjusting unit as well as a value representing the load of the engine are detected. For monitoring purposes, the variable representing the load and the adjustment value of the power adjusting unit are compared to each other. The maximum position of the power adjusting unit is limited in dependence upon the load and/or the engine rpm in such a manner that the range of high loads is not reached.
