Abstract: An exhaust aftertreatment system (14) including a housing (18, 218) with two or more inlets (230, 232) configured to receive separate entering exhaust streams from an engine (12). The system (14) may include two or more first exhaust treatment devices (262, 242), each configured to receive one of the separate entering exhaust streams in a first direction. The system may further include two or more redirecting flow passages (248, 254) configured to combine the separate exhaust streams into a merged exhaust stream that flows in a second direction about 180 degrees from the first direction and an intermediate flow region configured to divide the merged exhaust stream into two or more separate exiting exhaust streams.

Abstract: Starting systems for use with internal combustion engine have in the past used a variety of add on mechanical mechanisms to provide cold starting. Many of these systems fail to provide the option of controllably and modulatively varying the sequence and amount of the opening and closing of an intake or exhaust valve relative to a piston position in a cylinder bore. The present invention provides an electronic control system (119) outputting a discrete control signal (120), and an opening device (94) for unit actuation of each of the pair of valves (76) independently. The electronic control system (119) is programmable to respond in a first predetermined logic pattern for conventional operation of the engine (10) at which time each of the pair of valves (76) is in the open position (92) during the exhaust stroke. The electronic control system (119) is programmable to a second predetermined logic pattern to vary the operation of the valves associated with the respective bore (28) in the generally closed position (86) for a portion of the exhaust stroke before top dead center (44) during the exhaust stroke of the piston (38). The preestablished logic pattern controllably, sequentially and modulateably actuate the device (94) for unit actuation, moving each of the valves (76) independently between the open and closed position (86, 92) to effectively increase the heat within the bore (28) during the movement of a piston (38) from a bottom dead center position (44) to a top dead center position (46).

Abstract: Braking systems for use with internal combustion engine have in the past used a variety of mechanical mechanisms to activate the braking system in addition to the conventional cam, lifters, pushrods and rocker arms. Many of these systems fail to provide the option of controllably and modulatively varying the sequence and amount of the opening and closing of an intake or exhaust valve relative to a piston position in a cylinder bore. The present invention provides an electronic control system (119) outputting a discrete control signal (120), an opening device (94) for unit actuation of each of the pair of valves (76) independently. The electronic control system (119) is programmable to respond in a first predetermined logic pattern for conventional operation of the engine (10) at which time each of the pair of valves (76) are in the closed position (86) during the compression stroke. The electronic control system (119) is programmable to a second predetermined logic pattern to vary the operation of the valves associated with the respective bore (28) in the generally open position (92) during the compression stroke when the piston (38) in near the top dead center position. The preestablished logic pattern controllably, sequentially and modulateably actuate the device (94) for unit actuation, moving each of the valves (76) independently between the open and closed position (86, 92) to effectively resist the movement of a piston (38) from a bottom dead center position (44) to a top dead center position (46).

Abstract: Les systèmes de freinage moteur pour moteurs à combustion interne ont utilisé jusqu'à présent divers systèmes mécaniques s'ajoutant aux éléments classiques que sont les cames, les poussoirs, les tiges-poussoirs et les culbuteurs. La plupart de ces systèmes ne permettent pas de moduler à volonté ni le déroulement dans le temps ni la valeur de l'ouverture et de la fermeture des soupapes d'admission ou d'échappement par rapport à une position donnée du piston dans son cylindre. La présente invention porte sur un système de commande électronique (119) produisant un signal de commande discret (120) et sur un dispositif d'ouverture (94) régissant de manière unitaire le fonctionnement de chaque paire de soupapes (76) indépendamment. Ce système de commande électronique (119) est programmable, pour obéir à un premier modèle logique prédéterminé, pour le fonctionnement normal du moteur (10), qui détermine à quel moment les deux soupapes (76) sont en position fermée (86) pendant la course de compression. Le système de commade électronique (119) peut être programmé selon un deuxième modèle logique prédéterminé, qui modifie le fonctionnement des soupapes par rapport à leur cylindre correspondant (28), pour les amener en une position essentiellement ouverte (92) pendant la course de compression, lorsque le piston (38) est pratiquement au point mort haut. Le modèle logique prédéterminé permet de moduler à volonté, dans le temps et en progressivité, le dispositif (94) de fonctionnement unitaire, en actionnant chacune des soupapes (76) indépendamment, entre sa position ouverte et sa position fermée (86, 92) pour offrir une résistance efficace au mouvement du piston (38) entre sa position au point mort bas (44) et sa position au point mort haut (46).

Abstract: Les dispositifs de démarrage pour moteurs à combustion interne ont jusqu'à présent fait appel à divers systèmes mécaniques complémentaires assurant le démarrage à froid. Bon nombre de ces systèmes ne permettent pas de moduler à volonté et progressivement le déroulement dans le temps et la valeur de l'ouverture et de la fermeture d'une soupape d'admission ou d'une soupape d'échappement par rapport à une position donnée du piston dans son cylindre. La présente invention porte sur un système de commade électronique (119) produisant un signal de commande discret (120), et sur un dispositif d'ouverture (94) assurant de manière unitaire l'actionnement de chaque paire de soupapes (76), indépendamment. Le système de commande électronique (119) est programmable, de manière à obéir à un premier modèle logique prédéterminé assurant le fonctionnement normal du moteur (10), qui définit à quel moment chacune des deux soupapes (76) est en position ouverte (92) pendant la course d'échappement. Le système de commande électronique (119) est programmable selon un deuxième modèle logique prédéterminé, qui modifie le fonctionnement des soupapes par rapport à leur cylindre correspondant (28) dans leur position essentiellement fermée (86) pendant une partie de la course d'échappement, avant le point mort haut (44), pendant la course d'échappement du piston (38). Le modèle logique préétabli permet de moduler à volonté, quant au déroulement dans le temps et à la progressivité, le dispositif (94) d'actionnement unitaire, en déplaçant chacune des soupapes (76) indépendamment entre sa position ouverte et sa position fermée (86, 92), de manière à provoquer une augmentation efficace de la chaleur intérieure du cylindre (28) pendant le déplacement du piston (38) depuis le point mort bas (44) jusqu'au point mort haut (46).
