| Abstract: |
| Objective To improve the starting performance of medium duty vehicles & heavy duty vehicles in plateau and severe cold area. Methods A type of fuel heater used in plateau and severe cold environment was designed. The heater diffused the heat from combustion of fuel to the coolant to increase the temperature of the engine. Results In test room, the engine was started successfully within 25 min at －41 ℃ by using the fuel heater. In plateau and severe cold area, the engine was started successfully within 25 min by using the fuel heater. Conclusion The engine starting performance can be improved effectively by using the engine preheating equipment at －30~－41 ℃. |
