Abstract:
(EN) The invention relates to a method for operating a piston-type internal combustion engine with a turbocharger (8, 9), for carrying out the method according to claim 1, which comprises a first gas discharge valve (3.1) and at least one additional gas discharge valve (3.2) for each cylinder (I, II, III, IV). In said internal combustion engine, the respective gas discharge valves (3) are connected to their own valve train (5) which can in turn be controlled by a motor (6). The first gas discharge valves (3.1) create a first exhaust gas stream which impinges upon the turbocharger turbine (8) and the additional gas discharge valves (3.2) create a second exhaust gas stream, which is brought together with the first exhaust stream behind the turbocharger turbine (8) in relation to the direction of flow, in such a way that by controlling the first discharge valves and/or the second discharge valves as desired, an exhaust gas purification device which operates in a manner that is at least partially catalytic, is impinged upon by the first and/or the second exhaust gas stream.
(FR) L'invention concerne un procédé pour faire fonctionner un moteur à combustion interne à pistons doté d'un turbocompresseur (8, 9), moteur fonctionnant selon le procédé conforme à la revendication 1, lequel comporte une première soupape d'évacuation de gaz (3.1) et au moins une autre soupape d'évacuation de gaz (3.2) par cylindre (I, II, III, IV). Sur ledit moteur, les soupapes d'évacuation de gaz (3) sont chacune reliées à une commande de soupape (5) propre, qui est elle-même commandée par un moteur (6). Les premières soupapes d'évacuation de gaz (3.1) produisent un premier flux de gaz d'échappement qui alimente la turbine de suralimentation (8), les autres soupapes d'évacuation de gaz (3.2) génèrent un second flux de gaz d'échappement, qui est réuni au premier flux derrière la turbine de suralimentation (8), vu dans le sens du flux, de sorte que, par la sélection des premières soupapes d'évacuation de gaz et/ou des secondes soupapes d'évacuation de gaz, une installation d'épuration des gaz d'échappement, dont l'action est au moins partiellement catalytique, reçoit le premier et/ou le second flux de gaz d'échappement.
(DE) Die Erfindung betrifft ein Verfahren zum Betrieb einer Kolbenbrennkraftmaschine mit Abgasturbolader (8, 9), zur Durchführung des Verfahrens nach Anspruch 1, die je Zylinder (I, II, III, IV) ein erstes Gasauslaßventil (3.1) und wenigstens ein weiteres Gasauslaßventil (3.2) aufweist und bei der die Gasauslaßventile (3) jeweils mit einem eigenen über eine Motorsteuerung (6) steuerbaren Ventiltrieb (5) verbunden sind, wobei über die ersten Gasauslaßventile (3.1) ein erster Abgasstrom erzeugt wird, der die Laderturbine (8) beaufschlagt, und durch die weiteren Gasauslaßventile (3.2) ein zweiter Abgasstrom erzeugt wird, der mit dem ersten Abgasstrom in Strömungsrichtung gesehen hinter der Laderturbine (8) mit dem ersten Abgasstrom zusammengeführt wird, so daß durch eine wahlweise Ansteuerung der ersten Gasauslaßventile und/oder der zweiten Gasauslaßventile eine zumindest teilweise katalytisch wirkende Abgasreinigungseinrichtung mit dem ersten und/oder dem zweiten Abgasstrom beaufschlagt wird.
