Abstract
A turbocharger compressor bypass valve is disclosed. In one example, the compressor bypass valve operates inversely proportional to engine throttle operation. The approach may simplify compressor bypass valve control and reduced engine system complexity.
Claims20
A system for controlling turbocharger compressor surge, comprising:
- an engine throttle valve responsive to an engine torque command;
- and
- a compressor bypass valve in mechanical communication with the engine throttle.
A system for controlling turbocharger compressor surge, comprising:
- a turbocharger coupled to an engine;
- an engine throttle valve responsive to an engine torque command;
- and
- a compressor bypass valve mechanically coupled to the engine throttle valve, the compressor bypass valve positioned along an air flow path between an inlet and an outlet of a compressor of the turbocharger.
