| Abstract: | The structure and characteristic of vehicle separated cooling system were introduced.The 1D model for vehicle separated cooling system was established with AMESim software.By simulation calculation,the separated cooling system was compared with the traditional single-cycle cooling system.The results showed that the separated circulating cooling system had more advantages.For the separated circulating cooling system,the cold starting time was reduced by 87 s,the temperature of engine block was increased by 5.5 ℃,the fuel consumption was decreased by 5 percent,and the economy of engine was improved. |
