| 摘要 |
The present invention relates to a method for operating an internal combustion engine (1). The internal combustion engine (1) comprises a charge-air cooler (4) for cooling charge air and comprises a dosing valve (8). The charge air comprises exhaust gases which are conducted to the charge-air cooler (4), with an adjustable exhaust-gas recirculation rate, from an exhaust tract of the internal combustion engine (1). In the method, a dosing valve temperature of the dosing valve (8) is determined, and a charge-air temperature of the charge air is detected. Coolant is supplied to the dosing valve (8) and to the charge-air cooler (4) by means of a common adjustable coolant pump (6) as a function of the dosing valve temperature. Furthermore, an exhaust-gas recirculation rate is adjusted as a function of the charge-air temperature and the dosing valve temperature. |
