Zusammenfassung:	A variety of methods and arrangements for implementing a start/stop feature in a skip fire engine control system are described. In one aspect, the implementation of the start/stop feature involves automatically turning off an internal combustion engine under selected circumstances during a drive cycle. A determination is made that the engine should be restarted. During the engine startup period, the engine is operated in a skip fire manner such that a desired engine speed is reached L'invention concerne divers procédés et agencements pour mettre en œuvre une fonctionnalité de démarrage/arrêt dans un système de commande de moteur à cycle d'allumage sauté. Selon un premier, la mise en œuvre de la fonctionnalité de démarrage/arrêt consiste à arrêter automatiquement un moteur à combustion interne dans des circonstances sélectionnées pendant un cycle d'entraînement. On détermine que le moteur doit être redémarré. Pendant la période de démarrage du moteur, le moteur tourne selon un cycle d'allumage sauté de telle sorte qu'une vitesse de moteur souhaitée est atteinte.
