20110185991 | MOISTURE PURGING IN AN EGR SYSTEM - A two stage cooled EGR system for a turbocharged internal combustion engine with an intake air charge air cooler. The first EGR cooler is a liquid-to-air cooler and the second, low temperature EGR cooler, is an air-to-air cooler combining with the gas flow downstream of the intake air cooler. The system bypasses EGR flow through the low temperature EGR cooler during certain engine conditions such as low engine coolant temperature and a check valve allows a limited portion of un-cooled, pressurized intake air to be passed through the low temperature EGR cooler for scavenging of any residual moisture and ultimate consumption by the engine. | 08-04-2011 |
