一、不能少的部件
1、 Essential components
在维修汽车的时候，有些零部件因为人工疏忽漏装或少装，可是会产生很严重的危害。发动机的飞轮螺栓、连杆螺栓、传动轴螺栓漏装很容易引发严重的故障；发动机汽门锁片缺失会导致气门失控，撞坏汽车活塞；汽车油箱盖、水箱盖或是机油口盖少了，汽车运行过程中很容易将砂石灰尘带入机内，对其他汽车部件造成磨损。
When repairing a car, some parts may be omitted or underinstalled due to human negligence, which can cause serious harm. Missing flywheel bolts, connecting rod bolts, and transmission shaft bolts in the engine can easily cause serious malfunctions; Missing engine valve locking plates can cause valve loss of control and damage to car pistons; If the fuel tank cap, water tank cap, or oil port cap of a car is missing, it is easy to bring sand, stones, and dust into the engine during operation, causing wear and tear on other car components.
二、有的地方不能洗
2、 Some places cannot be washed
关于汽修方面的知识不太熟悉的修理工和新手司机会以为所有的零配件都可以清洗，其实这个想法是不对的。例如皮质零件不能清洗，在维修的时候只需要用干净抹布擦拭即可；发动机的纸质空气滤芯也只要用手轻拍即可上面的灰尘。
Repairers and novice drivers who are not very familiar with automotive repair knowledge may think that all spare parts can be cleaned, but this idea is actually incorrect. For example, if leather parts cannot be cleaned, they only need to be wiped with a clean cloth during maintenance; The paper air filter of the engine can also be easily cleaned of dust by lightly tapping it with your hand.
三、害怕热的部件
3、 Components that are afraid of heat
人怕热，汽车有些部件也同样怕热，例如汽车的发电机、起动器等电气设备线圈过热很容易烧毁报废；轮胎、橡胶密封圈长过热容易老化，缩短他们的使用寿命；润滑油变质有可能是车辆轴承过热，这需要注意了，过热的轴承很容易烧毁损坏车辆。
People are afraid of heat, and some parts of cars are also afraid of heat. For example, the coils of electrical equipment such as generators and starters in cars can easily burn out and be scrapped due to overheating; Tires and rubber seals are prone to aging due to prolonged overheating, which shortens their service life; Deterioration of lubricating oil may be due to overheating of vehicle bearings, which requires attention as overheated bearings can easily burn and damage the vehicle.
四、这些部件要避火
4、 These components need to avoid fire
我们都知道汽车不能靠近货源，容易引发爆炸。同时，在我们维修汽车的时候，轮胎、橡胶油封、三角胶带等橡胶制品，一定要远离火源，避免这些部件老化。冬天即将来临，很多车主或维修工会用喷灯加热，也需要注意了，要防止烧坏汽车线路和油路，避免引发火灾。
We all know that cars should not be close to the source of goods, which can easily cause explosions. At the same time, when repairing cars, rubber products such as tires, rubber seals, and triangular tape must be kept away from sources of fire to avoid aging of these components. Winter is approaching, and many car owners or maintenance workers use spray lamps to heat up. They also need to be careful to prevent burning out the car's wiring and oil lines, and avoid causing fires.
五、汽车也怕脏
5、 Cars are also afraid of getting dirty
别以为汽车长期接触路面就不怕脏了，空气滤清器、机油滤清器等汽车各类滤网过脏可不是好事，过脏会导致滤清效果变差，如果进入到油路气缸，还会对其他部件造成磨损，增加汽车故障的发生，严重的，还会影响到汽车正常启动。
Don't think that cars are not afraid of getting dirty after long-term contact with the road surface. Dirty air filters, oil filters, and other types of car filters are not a good thing. Dirty filters can lead to poor filtration efficiency. If they enter the oil cylinder, they can also cause wear and tear on other components, increase the occurrence of car malfunctions, and in serious cases, affect the normal start of the car.
六、害怕油的部件
6、 Parts that are afraid of oil
虽然汽车常年和汽油、机油打交道，但是也有很多害怕油的部件，这就需要我们再日常维修保养中需要注意了。汽车轮胎等橡胶制品对油类很敏感，接触会导致橡胶变软、脱皮，长期接触会产生严重的损坏腐蚀；此外，发动机的干式空气滤清器的纸质滤芯具有吸油性，一旦沾到汽油，会吸入大量的混合气到气缸内，加大汽车的油耗，降低发动机的功率，甚发生“飞车”的情况。
Although cars often deal with gasoline and engine oil, there are also many parts that are afraid of oil, which requires us to pay attention to in daily maintenance and repair. Rubber products such as car tires are very sensitive to oil, and contact can cause the rubber to soften and peel. Long term contact can cause serious damage and corrosion; In addition, the paper filter element of the engine's dry air filter has oil absorption properties. Once it comes into contact with gasoline, it will suck in a large amount of mixed air into the cylinder, increasing the car's fuel consumption, reducing the engine's power, and even causing "speeding".
