Diesel engine controlling method for motor vehicle, involves correcting set points of operating parameters of diesel engine based on estimation of clogging state of exhaust gas recirculation heat exchanger |
摘要 |
The method involves correcting set points of operating parameters of a diesel engine (1) based on estimation of a clogging state of an exhaust gas recirculation heat exchanger (6) e.g. air/air heat exchanger. The clogging state is estimated by measuring an equivalent section and thermal efficiency of the heat exchanger based on a recycled gas rate. The measured values are compared with cartographic values in models relative to the heat exchanger at an initial non-clogged state. An independent claim is also included for a device for implementing a diesel engine controlling method. |
