Title (EN) SPARK IGNITION COMBUSTION ENGINE CONTROL
(FR) COMMANDE DE MOTEUR À COMBUSTION À ALLUMAGE PAR ÉTINCELLES
Abstract:
(EN) According to the present invention, a combustion engine (1) is provided comprising: a spark plug (2) for igniting an air-fuel mixture in a combustion chamber (4), and a control device (24) capable of controlling sparking actions of the spark plug (2), wherein the control device (24) is configured to selectively carry out a spark-ignition stroke in which the air-fuel mixture is spark-ignited by the spark plug (2), and an activation stroke in which an ignition timing of the spark plug (2) is varied compared to the spark-ignition stroke, the activation stroke advantageously increasing or decreasing a tendency toward a no-spark combustion in a cycle of the combustion engine following the activation stroke.
(FR) La présente invention concerne un moteur à combustion (1) comprenant : une bougie d'allumage (2) servant à enflammer un mélange air-carburant dans une chambre de combustion (4), et un dispositif de commande (24) pouvant commander des actions d'allumage de la bougie d'allumage (2), le dispositif de commande (24) étant configuré pour mettre sélectivement en œuvre un temps d'allumage par étincelles dans lequel le mélange air-carburant est allumé par étincelles au moyen de la bougie d'allumage (2), et un temps d'activation dans lequel le moment d'allumage de la bougie d'allumage (2) varie par comparaison avec le temps d'allumage par étincelles, le temps d'activation augmentant ou diminuant de manière avantageuse une tendance vers une combustion sans étincelles dans un cycle du moteur à combustion à la suite du temps d'activation.
