Pay attention to the use of running in period. This is the basis for extending engine life. Jinan where repair Audi is more professional, new engine and overhaul engine in normal operation, must be in accordance with the specifications.

　　經常檢查緊固區域。柴油機或汽油機在使用過程中受振動和載荷的影響是不平等的，螺栓、螺母容易松動，而且各部件的調節螺栓應仔細檢查，以免造成松動而損壞部件。應及時檢查和調整氣門間隙、配油相位、供油提前角、噴油壓力和點火正時，確保發動機始終處于良好的技術狀態，以節約燃料，延長使用壽命。

　　Check fastening areas frequently. The influence of vibration and load on diesel engine or gasoline engine in use is unequal. The bolts and nuts are easy to loosen. Moreover, the adjusting bolts of all parts shall be carefully checked to avoid damage to the parts due to loosening. Check and adjust the valve clearance, oil distribution phase, oil supply advance angle, injection pressure and ignition timing in time to ensure that the engine is always in a good technical state, so as to save fuel and extend its service life.

　　保持油、水、氣和身體的清潔。如果燃油不純,它將使精確匹配的寶馬汽車維修零部件磨損,匹配的差距增加,導致漏油,油滴,電力供應壓力減少,差距較大,甚至導致石油道路堵塞,軸燃燒的瓷磚和其他嚴重的缺點;如果空氣中含有大量灰塵，會加速缸套、活塞和活塞環的磨損;如果冷卻水不純凈，就會增大冷卻系統的水垢，阻礙發動機散熱，潤滑狀況就會變差，機器零件就會嚴重磨損。如果車身表面不干凈，車身會被腐蝕，縮短使用壽命。

　　Keep oil, water, air and body clean. If the fuel oil is impure, it will make the precisely matched BMW maintenance parts wear, and the matching gap will increase, which will lead to oil leakage, oil drops, reduced power supply pressure, and even lead to the blockage of oil roads, ceramic tiles of shaft combustion and other serious disadvantages; if there is a large amount of dust in the air, it will accelerate the wear of cylinder liners, pistons and piston rings; If the cooling water is not pure, it will increase the scale of the cooling system, hinder the heat dissipation of the engine, the lubrication condition will become worse, and the machine parts will be severely worn. If the body surface is not clean, the body will be corroded and the service life will be shortened.

　　確保充足的油、水和空氣。如果汽油和空氣供應遲到或中斷，將有啟動困難，燃燒不良，功率下降，發動機不能正常運行等現象;如果供油不足或中斷，會使發動機潤滑不良，零件磨損嚴重，甚至出現燒瓦現象;如果冷卻水不足，機器溫度會過高，功率下降，磨損，降低使用壽命。

　　Ensure adequate oil, water and air. If the supply of gasoline and air is late or interrupted, it will be difficult to start, poor combustion, power reduction, and the engine can not operate normally; if the supply of oil is insufficient or interrupted, it will cause poor lubrication of the engine, serious wear of parts, and even tile burning; if the cooling water is insufficient, the temperature of the machine will be too high, power reduction, wear, and reduce the service life.
