Title
(EN) PREDICTIVE CORRECTION IN INTERNAL COMBUSTION ENGINES
(FR) CORRECTION PRÉDICTIVE DANS DES MOTEURS À COMBUSTION INTERNE
Abstract
(EN)
A method and system for reducing cycle to cycle variation of an engine is provided. The system may determine fuel injection characteristics and predict a gas burning rate or flame speed based on the fuel injection characteristics. The system may adjust an ignition timing in response to the predicted gas burning rate within the same engine cycle.
(FR)
La présente invention se rapporte à un procédé et à un système permettant de réduire les variations de cycle à cycle d'un moteur. Le système peut déterminer des caractéristiques d'injection de combustible et prédire la vitesse de combustion du gaz ou la vitesse de flamme sur la base des caractéristiques d'injection de combustible. Le système peut ajuster un réglage de calage de l'allumage en réponse à la vitesse de combustion du gaz prédite pendant le même cycle du moteur.
