Interstage exhaust gas recirculation system for a dual turbocharged engine having a turbogenerator system |
摘要 |
An internal combustion engine defined as having an engine block for internal combustion, a high-pressure turbocharger for delivering pressurized intake air to the engine block, a low-pressure turbocharger for delivering pressurized intake air to the high-pressure turbocharger, a turbogenerator for recovering heat energy from the exhaust gas downstream of the low-pressure turbocharger to generate electricity, and an exhaust gas recirculation (EGR) system comprising an EGR-pump drawing exhaust gas from an EGR inlet located between the low-pressure and high-pressure turbocharger turbines, wherein the EGR-pump controllably delivers exhaust gas to an EGR mixer in the pressurized intake air stream at a location between the low-pressure and high-pressure turbocharger compressors. An electronic control unit (ECU) is adapted to command the EGR-pump to deliver a desired EGR flow-rate to the engine block based on look-up tables and either open-loop and/or closed-loop control algorithms.
