摘要： A turbocharger system for a vehicle comprising a turbocharger, a tank for compressed gas and an exhaust manifold conduit in fluid communication with an inlet of the turbocharger. The tank is in fluid communication with the manifold conduit and is arranged and controlled to push compressed gas into the manifold conduit during a predetermined pulse duration time period for initial compressor spin up in the turbocharger.

摘要： A turbocharger system and method for a vehicle, wherein the system comprises a high pressure turbocharger and a low pressure turbocharger. Both the high and low pressure turbochargers are driven by exhaust gas on an exhaust side of the turbochargers. The system further comprises a first bypass conduit that bypasses the low pressure turbocharger during set events.
