SYSTEM AND METHOD FOR MANAGING CONDENSATION IN EGR SYSTEMS |
| 摘要 |
A system and method for condensation management in a low-pressure loop EGR system are provided. The system includes an EGR condensation temperature module configured to determine an EGR condensation temperature of recirculated exhaust gas upstream of an EGR cooler and an EGR coolant temperature controller communicably coupled to the EGR condensation temperature module. The EGR coolant temperature controller provides EGR coolant to the EGR cooler at or above the EGR condensation temperature. The system also includes a charge air condensation temperature module configured to determine a charge air condensation temperature of charge air upstream of a charge air cooler and a charge air coolant temperature controller communicably coupled to the charge air condensation temperature module. The charge air coolant temperature controller provides charge air coolant to the charge air cooler at or above the charge air condensation temperature. |

1. A low pressure loop exhaust gas recirculation (EGR) condensation management system comprising:
an EGR condensation temperature module configured to determine an EGR condensation temperature of recirculated exhaust gas upstream of an EGR cooler in the low pressure loop exhaust gas recirculation system; an EGR coolant temperature controller communicably coupled to the EGR condensation temperature module, the EGR coolant temperature controller configured to provide EGR coolant to the EGR cooler at or above the EGR condensation temperature; a charge air condensation temperature module configured to determine a charge air condensation temperature of charge air upstream of an charge air cooler in the low pressure loop exhaust gas recirculation system; and a charge air coolant temperature controller communicably coupled to the charge air condensation temperature module, the charge air coolant temperature controller configured to provide charge air coolant to the charge air cooler at or above the charge air condensation temperature. |
