| 摘要 |
The invention relates to a method for operating a rail vehicle, which has a diesel engine, an engine radiator, and a cooling circuit that connects the diesel engine to the engine radiator, a cooling liquid being circulated in the cooling circuit, wherein a cooling liquid temperature of the circulated cooling liquid and an outer air temperature of the atmospheric outer air are detected, the outer air temperature is compared with a previously defined outer air limit temperature, the cooling power of the engine radiator is set in such a way that the cooling liquid temperature corresponds as much as possible to a normal operating temperature if the outer air temperature is less than the outer air limit temperature, and the cooling power of the engine radiator is set in such a way that the cooling liquid temperature corresponds as much as possible to a lower operating temperature below the normal operating temperature if the outer air temperature is greater than the outer air limit temperature. |
