<p>A system for controlling an exhaust driven turbocharging system includes a turbocharger having an exhaust inlet, a discharge outlet, a compressor air inlet, and a compressor outlet, a compressor bypass valve having a control port, an inlet port, a discharge port, and a valve for opening and closing the discharge port, and an engine having an air inlet and an exhaust outlet, and may include a wastegate. In the system the compressor outlet of the turbocharger is connected to the air inlet of the engine and is connected to the inlet port of the compressor bypass valve. By controlling the compressor bypass valve and the wastegate higher turbine inlet pressures can be generated for use in other areas of the system. This is achieved by opening the compressor bypass valve in an unconventional area of the internal combustion engine's range where it would normally remain closed.</p> |
