Exhaust gas recirculation system diagnosing and controlling system for e.g. diesel engine, has regulation block regulating temperature of recycled gas via non linear action on bypass valve based on set point temperature of exhaust gas |
摘要 |
The system has an exhaust gas recirculation (EGR) pipe (8) for partially recirculation exhaust gas. A bypass pipe (9) of an EGR exchanger (82) is connected on a pipe (8) in upstream of a valve (81), and to the pipe (8) in downstream of the exchanger and in upstream of an EGR valve (83). A temperature sensor (101) measures temperature of recycled gas before admitting mixture with air into an engine. A regulation block (103) regulates the temperature of the recycled gas via a non linear action on a bypass valve (91) of the pipe (9) based on set point temperature of the gas. An independent claim is also included for a method for controlling an internal combustion engine. |
