经过长途行驶，汽车发动机内部可能沉积了一层会造成发动机耗油增加、功率降低甚至损伤的油泥，同时机油、防冻液、制动液可能损耗也比较大。
After long-distance driving, a layer of sludge may be deposited inside the car engine, which will increase the fuel consumption, reduce the power and even damage the engine. At the same time, the oil, antifreeze and brake fluid may also be consumed.
所以，我们要先检查发动机舱内的机油、制动液和防冻液，看油液是否充足、变质；如制动液变质，导致制动力不足，就应当及时更换。而如果防冻液也需要更换，需注意颜色不同的防冻液好不要混用，因为不同的防冻液因为成分不同，混用后往往影响实际效果。接着再检查动力总成、传动系统有无渗漏机油。
Therefore, we should first check the engine oil, brake fluid and antifreeze in the engine compartment to see whether the oil is sufficient and deteriorated; If the brake fluid deteriorates, resulting in insufficient braking force, it should be replaced in time. If the antifreeze also needs to be replaced, it should be noted that antifreeze with different colors should not be mixed, because different antifreeze often affects the actual effect after mixing because of different ingredients. Then check the powertrain and transmission system for oil leakage.
中途加油时，由于各地加油站的油品质量不一，有些汽油胶质含量过多、标号不够，会造成汽车发动机加速不良、油耗上升、尾气不合格等问题，使三元催化器失效。对此，我们可以对油路、油箱和喷油器进行清洗。
During midway refueling, due to the different quality of oil products in gas stations around the country, some gasoline has too much colloid and insufficient grade, which will cause problems such as poor acceleration of automobile engine, rising fuel consumption, unqualified exhaust and so on, and make the three-way catalyst ineffective. For this, we can clean the oil circuit, oil tank and fuel injector.
清洗车内
Clean the inside of the car
畅游回来后，我们的车内可能会有异味。这主要是两方面原因造成的。一是长时间行驶在路上，空气中的粉尘杂质多，容易堵住空调滤芯，这不仅会缩短空调使用寿命，而且容易滋生细菌，引发车内异味生成霉斑。二是我们难免在车上放物品或吃食物，食物残渣与物品往往会释放异味。
After Changyou comes back, there may be a peculiar smell in our car. This is mainly caused by two reasons. First, when driving on the road for a long time, there are many dust impurities in the air, which is easy to block the filter element of the air conditioner, which will not only shorten the service life of the air conditioner, but also easily breed bacteria, causing the odor in the car to produce mildew. Second, it is unavoidable for us to put items or eat food in the car, and food residues and items often release peculiar smell.
长时间处在这种异味环境中，人会感到头晕、恶心甚至患上呼吸道疾病。因此，要对车内做一次较为彻底的清洗。清理部位包括座椅、仪表盘、脚踏垫、座椅缝隙、车门内侧、坐垫、空调出风口、储物格、后备厢。而空调滤芯，除了清理干净再装回原位，还可直接换新。
People will feel dizzy, nauseated and even suffer from upper respiratory tract diseases after being exposed to this peculiar smell for a long time. Therefore, the interior of the car should be cleaned thoroughly. The cleaning parts include seats, instrument panels, footrests, seat gaps, inner side of doors, cushions, air conditioning vents, storage compartments, and trunk. The filter element of the air conditioner can be directly renewed in addition to being cleaned and then reinstalled.
济南宝马汽车专修人员认为清洗完，车内空气的异味会有效减淡，但我们也要注意多开车窗，通风透气，并保持车内干燥、整洁，从源头减少异味的产生。除此，还可购买一些车内除味产品，清新车内空气。
Jinan BMW special repair personnel believe that after cleaning, the odor of the air in the car will be effectively reduced, but we should also pay attention to opening more windows, ventilation, and keeping the car dry and tidy, so as to reduce the generation of odor from the source. In addition, you can also buy some in car deodorization products to freshen the air in the car.
After a comprehensive inspection and cleaning, I believe our car can be renewed and continue to be used in a better state. Of course, if you have questions about the maintenance of the car, you can follow our website http://www.lutongqixiu.com consulting service
