由于气温高、雨量多、灰尘大和辐射热强等原因，会使汽车尤其是发动机技术状况发生变化。为了适应汽车正常运行的需要，在夏季到来之前，应结合二级保养对全车进行一些必要的季节检查与调整，下面来讲讲吧。
Due to high temperature, heavy rainfall, heavy dust and strong radiant heat, the technical status of cars, especially engines, will change. In order to meet the needs of normal operation of the car, before the arrival of summer, we should carry out some necessary seasonal inspections and adjustments on the whole car in combination with secondary maintenance. Let's talk about it below.
1、加强冷却系的使用与保养:注意检查冷却系的密封情况、风扇皮带的松紧度、节温器的灵敏度和冷却水温度情况等，并注意有充足的冷却水。冷却系包括散热器、水套内粘附的水垢。因为水垢导热性能差，会严重影响散热。
1. Strengthen the use and maintenance of the cooling system: pay attention to check the sealing of the cooling system, the tightness of the fan belt, the sensitivity of the thermostat and the temperature of the cooling water, and pay attention to sufficient cooling water. Remove the scale adhered in the cooling system, including the radiator and water jacket. Because the thermal conductivity of scale is poor, it will seriously affect the heat dissipation.
2、发动机换用高粘度牌号的润滑油并适当缩短换油周期;变速器和差速器应换用夏季厚质齿轮油;轮毂轴承换用滴点较高的润滑脂，并按规定周期进行检查与维护;制动液在高温下可能产生气阻，应采用沸点高的制动液。
2. Replace the engine with high viscosity lubricating oil and appropriately shorten the oil change cycle; The transmission and differential should be replaced with summer thick gear oil; Replace the hub bearing with lubricating grease with high dripping point, and inspect and maintain it according to the specified cycle; Brake fluid may produce air resistance at high temperature, so brake fluid with high boiling point should be used.
3、调整化油器。适当降低浮子室油面高度，减少主喷管与阀的出油量，适当地推迟点火提前角。
3. Adjust the carburetor. Appropriately reduce the oil level height of the float chamber, reduce the oil output of the main nozzle and valve, and appropriately delay the ignition advance angle.
4、充电系的调整与保养。夏季行车，蓄电池会出现过充现象，电解液蒸发快，很易损坏，因此，需经常检查蓄电池的液面高度和电解液比重(电解液比重比冬季应小些)，经常向蓄电池加注蒸馏水;要保持加注口盖上通气孔通畅无阻塞，否则会发生蓄电池内部气压增大而使壳体炸裂;还应适当调整发电机调节器，减少发电机的充电电流。
4. Adjustment and maintenance of charging system. When driving in summer, the battery will be overcharged, and the electrolyte will evaporate quickly, which is easy to be damaged. Therefore, it is necessary to often check the liquid level height of the battery and the specific gravity of the electrolyte (the specific gravity of the electrolyte should be smaller than that in winter), and often fill the battery with distilled water; Keep the vent hole on the filler cap unobstructed, otherwise the internal air pressure of the battery will increase and the shell will burst; The generator regulator should also be adjusted appropriately to reduce the charging current of the generator.
5、防止爆裂。
济南奔驰汽车保养人员认为您应根据发动机压缩比选用相应辛烷值的汽油，如汽油牌号低于要求牌号时，可安装爆震限制器;要保持发动机以正常的工作温度;适当推迟点火提前角和加浓混合气。
5. Prevent bursting. Jinan Benz automobile maintenance personnel believe that you should choose gasoline with corresponding octane number according to the compression ratio of the engine. If the gasoline grade is lower than the required grade, you can install knock limiter; Keep the engine at normal operating temperature; Delay the ignition advance angle and enrich the mixture appropriately.
In summer, when the temperature is high, the temperature in the tire increases, and the internal pressure increases, which is easy to blow out. Therefore, when the car is running in summer, pay more attention to the temperature and pressure of the tires and check them frequently to maintain the specified pressure standard. Do a good job of maintenance, so that your car can be used more comfortable and longer. Come to the website for more information http://www.lutongqixiu.com Get it!
