Abstract
(EN)
A supercharged internal combustion engine (40) which includes a turbocharger (10) which includes a compressor (12) and a turbine (14) in communication with ambient air wherein that air is pressurized by the compressor (12). An intercooler (20), in communication with the outlet of the compressor (12), reduces the temperature of the pressurized air. An intake manifold (30), in communication with the outlet of the intercooler (20), distributes the air into the engine. The engine (40) has an exhaust manifold (19) in communication with the turbine (14) of the turbocharger (10). A fuel metering means (50) introduces fuel into the engine (40) such that the equivalence ratio of the air/fuel mixture is less than the equivalence ratio at the smoke point or a ratio of 0.85 to 0.95. The supercharging parameter of the of air is greater than the supercharging parameter of the air at the smoke point or at a ratio of 0.85 to 0.95.

L'invention concerne un moteur (40) à combustion interne suralimenté équipé d'un turbocompresseur (10) comprenant un compresseur (12) et une turbine (14) communiquant avec l'air ambiant, ce dernier étant pressurisé par le compresseur (12). Un refroidisseur (20) intermédiaire communiquant avec la sortie du compresseur (12), abaisse la température de l'air pressurisé. Un collecteur (30) d'admission communiquant avec la sortie du refroidisseur (20) intermédiaire distribue l'air dans le moteur. Le moteur (40) est équipé d'un collecteur (19) d'échappement communiquant avec la turbine (14) du turbocompresseur (10). Des moyens (50) de réglage d'alimentation introduisent le carburant dans le moteur (40) à raison d'une quantité telle que le coefficient d'équivalence du mélange air/carburant est inférieur au coefficient d'équivalence au point de fumée ou à un coefficient de 0, 85 à 0,95. Le paramètre de suralimentation de l'air plus grand que le paramètre de suralimentation de l'air au point de fumée, ou un coefficient de 0,85 à 0,95.
