Abstract (en)
[origin: EP1729001A1] The method, using a sensor (SR) after the engine's exhaust manifold (CE), consists of establishing a physical model representing the real time ejection of gases from each of the cylinders and their passage through the exhaust circuit as far as the sensor and defining an estimation of the richness measured by the sensor from at least one variable of the model. The model is connected to a non-linear adaptive estimator which takes account of the estimated richness and produces a real-time estimation of the fuel mixture richness in each of the cylinders.
