Abstract
(EN)
Based on one or more monitored operation parameters of an internal combustion engine, a set of engine operation conditions necessary to provide combustion stability in a combustion volume of the engine, optimized fuel efficiency, and minimized production of pollutants such as nitrogen oxides, carbon monoxide, and unburned hydrocarbons can be determined. The new set of engine operation conditions can be dynamically implemented in response to changing engine loads and changing engine speeds to maintain a combustion mixture and combustion conditions within a combustion chamber of the engine constrained flammability limits, pollutant generation rates, and fuel efficiency considerations. Related articles, systems, and methods are described.
(FR)
Sur la base d'un ou plusieurs paramètres de fonctionnement d'un moteur à combustion interne faisant l'objet d'un suivi, il est possible de déterminer un ensemble de conditions de fonctionnement d'un moteur nécessaires pour assurer une bonne stabilité de la combustion dans le volume de combustion du moteur, un meilleur rendement du carburant et une minimisation de la production de polluants tels que les oxydes d'azote, le monoxyde de carbone et les hydrocarbures non brûlés. Ledit nouvel ensemble de conditions de fonctionnement d'un moteur peut être mis en œuvre de façon dynamique en réponse à un changement de la charge et de la vitesse du moteur afin de maintenir, dans la chambre de combustion du moteur, un mélange de combustion et des conditions de combustion respectant des limites contraintes d'inflammabilité, de taux de génération de polluants et de rendement du carburant. L'invention concerne également des articles, systèmes et procédés associés.
