초록 ▼

The present invention relates to an internal combustion engine and more particularly to an internal combustion engine which includes a turbocharger system having at least one smaller exhaust gas turbocharger and at least one larger exhaust gas turbocharger, as well as means for controlling the exhaust gas and intake air flow to the respective turbochargers. The turbochargers and control means are interconnected to provide pressurized intake air throughout the entire operating range of the internal combustion engine, while effectively bypassing the smaller exhaust gas turbocharger during operating conditions which produce high exhaust gas volumes. The operating characteristics of this turbocharger system are matched with the operating range of an internal combustion engine to provide improved performance, efficiency, transient response and reliability, while reducing maintenance and undesirable emissions.

대표청구항 ▼

A turbocharger system for an internal combustion engine having an exhaust port and an intake port comprising: a first turbocharger having an operational limit and a first turbine connected to the exhaust port of the engine via a first exhaust line and a first compressor connected to the intake port of the engine via a first intake line; a second turbocharger relatively larger than said first turbocharger and having a second turbine connected to said first turbine via a second exhaust line and a second compressor connected to said first compressor via a second intake line; a first exhaust flow control means between said first exhaust line and said second exhaust line in parallel with said first turbine for bypassing at least a portion of the exhaust from the engine past said first turbine to said second turbine, said first exhaust flow control means being biased to be at least partially closed but being openable solely in response to an exhaust pressure increase from the exhaust port sufficient to overcome said bias such that sufficient exhaust is diverted to said second turbine that said first turbine is prevented from exceeding said operational limit when the operating conditions of the engine increase; and an intake air control means between said first compressor line and said second compressor line in parallel with said first compressor for bypassing at least a portion of the air from said second compressor past said first compressor to the engine, said intake air control means being biased closed but being openable in response to an intake air pressure increase from said second compressor above a predetermined pressure.
