| 1 | METHOD TO OPTIMIZE ENGINE OPERATION USING ACTIVE FUEL MANAGEMENT | US15245652 | 2016-08-24 | US20180058345A1 | 2018-03-01 | Allen B. Rayl; Donovan L. Dibble; Darrell W. Burleigh; Steven J. Haase |
| A method for operating an internal combustion engine includes providing a vehicle having an internal combustion gasoline engine including multiple cylinders and wherein the engine is capable of running on at least one of a plurality firing fractions, providing a vacuum offset (Offsetvac) to adjust airflow capacity for each of the plurality of firing fractions, determining a torque capacity of each of the plurality firing fractions and a plurality of available firing fractions that provides at least enough torque capacity to accommodate a current torque requested (Treq), determining a plurality of viable firing fractions of the plurality of available firing fractions, and determining and implementing an optimal firing fraction of the viable firing fractions if the optimal firing fraction provides enough fuel economy benefit over a current firing fraction. | ||||||

| 3 | MOTEUR A COMBUSTION INTERNE MUNI D'UN SYSTEME DE RECIRCULATION DES GAZ D'ECHAPPEMENT (EGR) ET PROCEDE DE COMMANDE DE LA RECIRCULATION DES GAZ ASSOCIE | EP13723182.5 | 2013-04-18 | EP2855902A1 | 2015-04-08 | CHAPEL, Julien; RIBAULT-MENETIERE, Martin |
| The invention concerns an internal combustion engine (1) comprising an air intake manifold (8), an exhaust manifold (17), a plurality of cylinders (2.1-2.4) each having a combustion chamber (5.1-5.4), and a recirculation conduit (22) capable of reinjecting all the exhaust gases from the combustion chamber (5.4) of at least one of the cylinders (2.4), referred to as the EGR-dedicated cylinder, into the air intake manifold (8). According to the invention, the engine (1 ) further comprises a control system (40, 41) configured to temporarily inhibit combustion inside the combustion chamber (5.4) of the EGR-dedicated cylinder (2.4). The invention also relates to the associated method for controlling the recirculation of gases. | ||||||
