由于氣溫高、雨量多、灰塵大和輻射熱強(qiáng)等原因，會(huì)使汽車尤其是發(fā)動(dòng)機(jī)技術(shù)狀況發(fā)生變化。為了適應(yīng)汽車正常運(yùn)行的需要，在夏季到來(lái)之前，應(yīng)結(jié)合二級(jí)保養(yǎng)對(duì)全車進(jìn)行一些必要的季節(jié)檢查與調(diào)整，下面來(lái)講講吧。

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、加強(qiáng)冷卻系的使用與保養(yǎng):注意檢查冷卻系的密封情況、風(fēng)扇皮帶的松緊度、節(jié)溫器的靈敏度和冷卻水溫度情況等，并注意有充足的冷卻水。清除冷卻系包括散熱器、水套內(nèi)粘附的水垢。因?yàn)樗笇?dǎo)熱性能差，會(huì)嚴(yán)重影響散熱。

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、發(fā)動(dòng)機(jī)換用高粘度牌號(hào)的潤(rùn)滑油并適當(dāng)縮短換油周期;變速器和差速器應(yīng)換用夏季厚質(zhì)齒輪油;輪轂軸承換用滴點(diǎn)較高的潤(rùn)滑脂，并按規(guī)定周期進(jìn)行檢查與維護(hù);制動(dòng)液在高溫下可能產(chǎn)生氣阻，應(yīng)采用沸點(diǎn)高的制動(dòng)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、調(diào)整化油器。適當(dāng)降低浮子室油面高度，減少主噴管與閥的出油量，適當(dāng)?shù)赝七t點(diǎn)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、充電系的調(diào)整與保養(yǎng)。夏季行車，蓄電池會(huì)出現(xiàn)過(guò)充現(xiàn)象，電解液蒸發(fā)快，很易損壞，因此，需經(jīng)常檢查蓄電池的液面高度和電解液比重(電解液比重比冬季應(yīng)小些)，經(jīng)常向蓄電池加注蒸餾水;要保持加注口蓋上通氣孔通暢無(wú)阻塞，否則會(huì)發(fā)生蓄電池內(nèi)部氣壓增大而使殼體炸裂;還應(yīng)適當(dāng)調(diào)整發(fā)電機(jī)調(diào)節(jié)器，減少發(fā)電機(jī)的充電電流。

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。濟(jì)南奔馳汽車保養(yǎng)人員認(rèn)為您應(yīng)根據(jù)發(fā)動(dòng)機(jī)壓縮比選用相應(yīng)辛烷值的汽油，如汽油牌號(hào)低于要求牌號(hào)時(shí)，可安裝爆震限制器;要保持發(fā)動(dòng)機(jī)以正常的工作溫度;適當(dāng)推遲點(diǎn)火提前角和加濃混合氣。

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.

夏季氣溫高，輪胎內(nèi)溫度升高，內(nèi)氣壓增大，容易爆胎。因此，汽車夏季運(yùn)行時(shí)，應(yīng)對(duì)輪胎的溫度和氣壓多加注意并經(jīng)常檢查，保持規(guī)定的氣壓標(biāo)準(zhǔn)。做好保養(yǎng)事項(xiàng)，讓您的愛車能使用的更舒心，更長(zhǎng)久。更多信息就來(lái)網(wǎng)站http://m.gxnn10z.com獲取吧！

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://m.gxnn10z.com Get it!
