Abstract (en)

[origin: DE19520605C1] Adjustments (10) which will affect the combustion in each successive cycle are made by a fuzzy or conventional PI(D) controller (9) operating on outputs taken during the preceding cycle from a stationary controller (6) of optimised ignition timing, fuel injection start and cut-off, and throttle opening, and from an operating-point characteristic memory (8) and a power and consumption calculator (7).The actual combustion function of the engine (1) is worked out by a neural net (4) and compared (5,6) with a set-point (3) and another stored characteristic (6 bis). The set-point is calculated from the measured actual condition (2) of the engine.
