Hot area
In use, according to the characteristics of high temperatures in hot areas, in order to meet the normal operation of the car, the engine should be overheated.
Do not exceed the engine temperature of 95 °C. Check the amount of cooling water frequently and fill it up in time. When “oil resistance†occurs in the oil circuit, stop and cool down and take preventive measures to reduce the “air resistanceâ€. Always check the tire pressure and temperature. If the fetal temperature is too high, the shade should be stopped to cool down. It is forbidden to use cold water or deflation method to cool down the temperature, otherwise it will accelerate the damage of the tire.
Pay attention to checking the level of the battery and the electrolyte density. Adjust the generator regulator to reduce the generator's charge current. Before entering the summer, seasonal maintenance should be carried out. According to the provisions of the vehicle's operating instructions, replace the oil used in the summer engine, replace the gear oil for the transmission and the main reducer in summer, and use the CD-grade 15W/40 diesel engine oil for the EQ1141G model power steering oil.
Highlands
The climate of the plateau region is characterized by thin air, low air pressure, and deteriorating engine inflation. As a result, engine power performance will be significantly reduced, fuel consumption will increase, and economic performance will deteriorate.
Therefore, the use of cars in the plateau area should pay attention to the following matters. When the mainland vehicle is used at a plateau, the main fuel supply system and the ignition advance angle of the carburetor of the used car should be adjusted to meet the needs of use. Drivers with Dongfeng EQ1141G and EQ1118G series exhaust brake devices should pay attention to the use of exhaust brakes to improve braking performance when used in highland areas.
When diesel vehicles are used in plateau areas, they should be adjusted to reduce the maximum fuel injection volume of fuel injection pumps so as to adapt to the climate characteristics of the plateau areas, so that the fuel burns sufficiently and the emission of black smoke is prevented. When a car climbs a long slope, the engine cooling water is prone to overheating, and on downhill slopes, excessive cooling and even freezing are liable to occur. Therefore, special attention must be paid to maintaining the normal temperature of the cooling water and adjusting the shutters in time. At the same time, it should also pay attention to check the amount of cooling water, if necessary, add water.
