Method for controlling internal combustion engine e.g. stroke or rotary-piston engine, of motor car, involves determining maximum and minimum rotation speed values in region of time course in which speed falls below predetermined speed

摘要

The method involves detecting a time course of rotation speed of an internal combustion engine (1). Maximum values and minimum values of rotation speed are determined in a region of the time course in which rotation speed falls below predetermined rotation speed. The engine is controlled by referring the maximum values and minimum values of the rotation speed when the determined maximum values and minimum values of the rotation speed fall below the predetermined rotation speed, where the predetermined rotation speed corresponds to rotation speed of the engine in an idle state. Independent claims are also included for the following: (1) a device for controlling an internal combustion engine (2) an internal combustion engine.
