PROCESS FOR DETECTING CYCLICAL FLUCTUATIONS IN COMBUSTION IN AN INTERNAL COMBUSTION ENGINE.

摘要

Running instability values which are proportional to variations in the angular speed of the crankshaft are used to determine interval values from the average of the instability values relating to consecutive combustion cycles by comparison of the current instability values with the associated mean value; the interval values are proportional to the cyclical fluctuations in combustion. The interval value is then compared with a cylinder-specific limit value and indicates cyclical fluctuations in combustion if it exceeds the limit value.
