TURBOCHARGER

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.

1. A turbocharger system for a vehicle, the system comprising;
a turbocharger; an exhaust manifold conduit being in fluid communication with an inlet of the turbocharger; a tank for compressed gas, the tank being in fluid communication with the manifold conduit and being arranged to push a pulse of compressed gas into the manifold conduit during a predetermined pulse duration time period for initial compressor spin up in the turbocharger; a first control unit; and a load sensor connected to the first control unit, the load sensor being arranged to sense a desired engine load from a driver of the vehicle; wherein the first control unit is arranged to estimate a desired change in engine load dependent on received input from the load sensor, estimate a desired turbocharger effect dependent on the estimated desired change in engine load, and control the tank to discharge a predetermined pulse of compressed air dependent on the estimated desired turbocharger effect.
