RAILCAR COMPRISING A DIESEL ENGINE AND METHOD FOR COOLING A DIESEL ENGINE OF A RAILCAR

摘要

The invention is directed to a cooling system for an internal combustion engine of a vehicle to a vehicle comprising such a cooling system, and to a method for cooling an internal combustion engine of a vehicle, in particular a diesel railcar. The cooling system has a first cooling liquid passage 1 for conveying cooling liquid flowing from a cooling liquid outlet of said internal combustion engine 3 to an inlet of a radiator device 4, a second cooling liquid passage 2 for conveying cooling liquid from an outlet of said radiator device to an cooling liquid inlet of said internal combustion engine 3, and a heat accumulator 15 connected to the first cooling liquid passage. According to the invention the cooling system is relieved of heat load peaks by taking up heat peaks of the cooling liquid with the heat accumulator 15 during high heat load periods of the cooling system and by discharging the heat accumulator 15 during low heat load periods by transferring heat stored in the heat accumulator 15 to the cooling system and/or a heating system connected thereto.
