Title (EN) INTERNAL COMBUSTION ENGINE WITH COMPRESSOR FUNCTION
(FR) MOTEUR A COMBUSTION INTERNE COMPRENANT UNE FONCTION DE COMPRESSEUR
Abstract:
(EN) The invention relates to an internal combustion engine with compressor function. One or more of the cylinders of the engine has an extra exhaust valve (11, 12) in the cylinder head. The engine has a fuel injection system with electric unit injectors (5), and the control system (20) of the system cooperates with a pressure means (21) which controls the extra exhaust valve. When a cylinder is to work as a compressor, a command is sent to the control unit to cut off the supply of fuel to the cylinder at the same time as a piston element (15) connected to the extra valve is subjected to pressure to open the valve.
(FR) Cette invention concerne un moteur à combustion interne comprenant une fonction de compresseur. Au moins un des cylindres du moteur comporte une soupape d'échappement supplémentaire (11, 12) dans la culasse. Le moteur comprend un système d'injection de carburant pourvu de pompes électriques combinées à des injecteurs (5) et le système de commande (20) du système coopère avec un système de pression (21) qui commande la soupape d'échappement supplémentaire. Lorsqu'un cylindre fonctionne en tant que compresseur, une commande est transmise à l'unité de commande afin de stopper l'alimentation en carburant vers le cylindre en même temps que l'élément de piston (15) connecté à la soupape supplémentaire reçoit de la pression pour ouvrir la soupape.
