| description | A closed-loop control algorithm that reduces the increases in nitrogen oxides (NOx) commonly observed with biodiesel combustion while retaining particulate matter (PM) reductions with variable biodiesel blend fractions. One embodiment includes a control algorithm that is closed-loop with regards to combustible oxygen mass fraction (COMF) instead of exhaust gas recirculation (EGR) fraction. Yet another algorithm includes biodiesel blend estimation and "fuel-flexible" accommodation. A physics-based model has also been developed which predicts experimentally observed engine performance and emissions for biodiesel.
Cette invention concerne un algorithme de contrôle en boucle fermée qui réduit les augmentations d'oxydes d'azote (NOx) couramment observées lors de la combustion des biocarburants, tout en conservant les réductions de matières particulaires (PM) avec des fractions variables de mélanges de biocarburants. Un mode de réalisation selon l'invention comprend un algorithme de contrôle qui est en boucle fermée par rapport à la fraction massique d'oxygène combustible (COMF) au lieu de la fraction de recirculation des gaz d'échappement (EGR). Un autre algorithme encore comprend l'estimation d'un mélange de biocarburants et une adaptation « flexible en carburant ». Un algorithme de modélisation physique qui prédit la performance moteur expérimentalement observée et les émissions pour le biocarburant a également été développé. |
