Title
(EN) A CONTROLLER AND A METHOD FOR CONTROLLING AN INTERNAL COMBUSTION ENGINE
(FR) DISPOSITIF DE COMMANDE ET PROCÉDÉ DE COMMANDE D'UN MOTEUR À COMBUSTION INTERNE
Abstract
(EN)
Aspects of the present invention relate to a controller for controlling operation of an internal combustion engine, a control system, an internal combustion engine, a vehicle, a method and a non-transitory computer readable medium. The controller is configured to, during fuel cut, cause opening of an intake valve of a cylinder of the internal combustion engine to enable air having a mass to enter the cylinder. The mass is below a first range of masses which enable the internal combustion engine to provide combustion torque.
(FR)
La présente invention, selon certains aspects, concerne un dispositif de commande permettant de commander le fonctionnement d'un moteur à combustion interne, un moteur à combustion interne, un véhicule, un procédé et un support non transitoire lisible par ordinateur. Le dispositif de commande est conçu pour, pendant une coupure de carburant, provoquer l'ouverture d'une soupape d'admission d'un cylindre du moteur à combustion interne pour permettre une entrée d'air ayant une certaine masse dans le cylindre. La masse est inférieure à une première plage de masse qui permet au moteur à combustion interne de fournir un couple de combustion.
