Title (EN) A METHOD OF OPERATING A FOUR STROKE INTERNAL COMBUSTION ENGINE SYSTEM
(FR) PROCÉDÉ DE COMMANDE D'UN SYSTÈME DE MOTEUR À COMBUSTION INTERNE À QUATRE TEMPS
Abstract:
(EN) The invention relates to a method of operating a four stroke internal combustion engine system (1), the engine system (1) comprising:- a four stroke internal combustion engine (2) provided with an intake duct (5), - a turbo compressor (6") arranged to compress intake flow in the intake duct (5), and - a displacement machine (7) provided in the intake duct (5) downstream the turbo compressor (6"), wherein the displacement machine (7) is arranged to displace intake flow from an inlet to an outlet thereof. The method comprises the step of: operating the displacement machine (7) in a first mode where a pressure ratio (PR) given by a pressure at the outlet of the displacement machine (7) divided by a pressure at the inlet of the displacement machine (7) is substantially equal to 1. The invention also relates to a four stroke internal combustion engine system arranged to be operated by the above method.
(FR) Cette invention concerne un procédé de commande d'un système de moteur à combustion interne à quatre temps (1), le système de moteur (1) comprenant : -un moteur à combustion interne à quatre temps (2) pourvu d'un conduit d'admission (5), - un turbocompresseur (6") conçu pour comprimer un flux d'admission dans le conduit d'admission (5), et - une machine de déplacement (7) disposée dans le conduit d'admission (5) en aval du turbocompresseur (6"), la machine de déplacement (7) étant conçue pour déplacer le flux d'admission d'une entrée à une sortie de celui-ci. Le procédé comprend l'étape consistant à : actionner la machine de déplacement (7) dans un premier mode dans lequel un rapport de pression (PR) donné par une pression à la sortie de la machine de déplacement (7) sur une pression à l'entrée de la machine de déplacement (7) est sensiblement égal à 1. L'invention concerne en outre un système de moteur à combustion interne à quatre temps conçu pour être commandé par le procédé ci-dessus.
