Title (EN) METHOD FOR OPERATING A GAS ENGINE
(FR) PROCÉDÉ POUR FAIRE FONCTIONNER UN MOTEUR À GAZ
(DE) VERFAHREN ZUM BETREIBEN EINES GASMOTORS
Abstract:
(EN) The invention relates to a method for operating a gas engine having at least one combustion chamber, in particular for a motor vehicle, wherein a gaseous fuel is injected directly into the combustion chamber in order to operate the gas engine, the gaseous fuel being injected directly into the combustion chamber within a working cycle of the gas engine during at least two phases (P1, P2) spaced apart from each other in time, the at least two phases (P1, P2) beginning and ending before the first ignition occurring within the working cycle.
(FR) L'invention concerne un procédé pour faire fonctionner un moteur à gaz comportant au moins une chambre de combustion, en particulier pour un véhicule automobile, consistant à injecter directement dans cette chambre de combustion un carburant gazeux pour faire fonctionner le moteur à gaz, ce carburant gazeux étant injecté directement dans la chambre de combustion lors d'un cycle de fonctionnement du moteur à gaz pendant au moins deux phases (P1, P2) temporellement espacées, ces deux phases (P1, P2) commençant et se terminant temporellement avant le premier allumage ayant lieu pendant le cycle de fonctionnement.
(DE) Die Erfindung betrifft ein Verfahren zum Betreiben eines wenigstens einen Brennraum aufweisenden Gasmotors, insbesondere für ein Kraftfahrzeug, bei welchem ein gasförmiger Kraftstoff zum Betreiben des Gasmotors direkt in den Brennraum eingeblasen wird, wobei der gasförmige Kraftstoff innerhalb eines Arbeitsspiels des Gasmotors während wenigstens zweier zeitlich voneinander beabstandeter Phasen (P1, P2) direkt in den Brennraum eingeblasen wird, wobei die wenigstens zwei Phasen (P1, P2) zeitlich vor der ersten innerhalb des Arbeitsspiels stattfindenden Zündung beginnen und enden.
