  • System and method for operating a high pressure compressor bypass valve in a two stage turbocharger system
    Patent number: 9109546
    Abstract: A system and method for controlling air flow in an engine system. In one embodiment, the system includes an engine, a turbocharger coupled to the engine, and a compressor bypass valve coupled to the turbocharger and to the engine. The compressor bypass valve includes a mechanism that allows the compressor bypass valve to be closed by default and allows the compressor bypass valve to be actuated passively when acted upon by a boost pressure when the boost pressure increases above a predefined pressure threshold. According to the system and method disclosed herein, the compressor bypass valve is passive, and thus controls air flow to the engine without requiring active control circuitry or logic.
