Title (DE) VARIABLER VENTILTRIEB EINER KOLBEN-BRENNKRAFTMASCHINE
(EN) VARIABLE VALVE DRIVE FOR A RECIPROCATING INTERNAL COMBUSTION ENGINE
(FR) COMMANDE DE SOUPAPES VARIABLE D'UN MOTEUR A COMBUSTION INTERNE A PISTONS
Abstract:
(DE) Die vorliegende Erfindung betrifft eine Kolbenbrennkraftmaschine eines Kraftfahrzeuges mit einer Steuerung zur zyklus-synchronen Umschaltung von Fremdzündung in eine kontrollierte Selbstzündung und umgekehrt, wobei eine Ventilgruppe eines Zylinders mit mehreren Ein- und Auslassventilen versehen ist und einer Öffnungsdauer der Ventilgruppe auf die Ein- und/oder Auslassventile verschieden aufgeteilt ist. Weiterhin werden Verfahren zur zyklus-synchronen Umschaltung angegeben.
(EN) The invention relates to a reciprocating internal combustion engine of a motor vehicle comprising a controller for cyclically-synchronously switching from spark ignition to controlled self-ignition and vice versa. A valve group of a cylinder is provided with several intake valve and discharge valves, an opening period of the valve group being distributed differently to the intake valves and/or the discharge valves. Also disclosed are cyclical synchronous switching methods.
(FR) L'invention concerne un moteur à combustion interne à pistons d'un véhicule automobile, qui comprend un mécanisme de commande pour la commutation, synchronisée avec le cycle, d'un allumage externe sur un auto-allumage contrôlé et inversement. Selon l'invention, un groupe de soupapes d'un cylindre présente plusieurs soupapes d'admission et d'échappement et une durée d'ouverture du groupe de soupapes est répartie différemment entre les soupapes d'admission et/ou d'échappement. L'invention concerne également des procédés de commutation synchronisée avec le cycle.
