Title
(EN) TURBOCHARGER SYSTEM FOR AIR-THROTTLED ENGINES
(FR) SYSTÈME DE TURBOCOMPRESSEUR POUR MOTEURS ÉQUIPÉS D'UN OBTURATEUR D'AIR
Abstract
(EN)
A turbocharger system for an air-throttled engine includes a variable flow expander (VFE) in the intake air conduit system that supplies intake air to the engine. At part-load operation, the VFE expands the air by an amount that is controllable, and thus regulates the air flow as needed by the engine. The power extracted by the VFE from the intake air flow is fed to the turbocharger, which helps to achieve quicker turbocharger response and improve scavenging of exhaust gases from the engine. The VFE can be a variable expansion ratio turbine.
(FR)
La présente invention concerne un système de turbocompresseur pour un moteur équipé d'un obturateur d'air qui comprend un dispositif d'accroissement du débit (DAD) dans le système de conduit d'air d'admission qui fournit l'air d'admission au moteur. Lors d'un fonctionnement à charge partielle, le DAD accroît la quantité d'air de manière réglable et régule ainsi le flux d'air en fonction des besoins du moteur. La puissance extraite par le DAD à partir du flux d'air d'admission est envoyée au turbocompresseur, ce qui permet d'obtenir une réponse du turbocompresseur plus rapide et d'améliorer l'évacuation des gaz d'échappement du moteur. Le DAD peut être une turbine à rapport d'expansion variable.
