Abstract
The amount of air being inducted into the cylinders of an internal combustion engine is detected and a signal indicative thereof is sampled at a predetermined intervals. The difference between two sampled values is used with the time required for a single induction phase to be carried out, to predict the total amount of air which will be inducted into each cylinder. Utilizing this approximation the amount of fuel which should be injected or otherwise supplied to the engine can be accurately determined and thus enable accurate real-time cycle to cycle A/F control.
