Abstract (en)
[origin: EP1375858A1] The supercharger (30) is connected to the IC engine (33) by the HP exhaust gas (31) and supercharged air (32) ducts the width of the former being variable. The gas housing (34) can be rotated approx. 250 relative to the air housing. The aim is to line-up the openings of these ducts to coordinate the operation of the charger with a specific characteristic. A pipe (46) connects the supercharged air duct to the exhaust gas duct and is fitted with an electronically controlled non-return valve (47). This enables positive pressure surges in the air duct to be transferred to the exhaust gas duct.
