汽车作为经常在外面日晒雨淋的交通工具，自然非常容易在雨天受潮短路，为了延长汽车的使用寿命，也为了保证我们的行车安全，今天
济南宝马汽车专修厂家就来讲讲宝马汽车点火启动与制动除水的事项！
As a vehicle that is often exposed to the sun and rain outside, cars are naturally very prone to moisture and short circuits in rainy days. In order to extend the service life of the car and ensure our driving safety, today's BMW Automotive Repair Factory in Jinan will talk about the issues of ignition starting and braking water removal for BMW vehicles!
点火启动
Ignition start
雨天，车主经常会碰到发动机不易启动的毛病，有时即使勉强启动起来，也是有气无力的。这种毛病大的可能是出自点火系统因潮湿而产生的漏电。此外，可能是一到下雨天气变凉了，而封在分电盘内的热空气就有可能凝结成水滴而造成分电盘内部的小水灾，因而丧失了正常的点火功能。
On rainy days, car owners often encounter problems with the engine that are difficult to start, and sometimes even if they reluctantly start up, they are weak. The most likely cause of this problem is electrical leakage from the ignition system due to humidity. In addition, it may be that when it rains and becomes cool, the hot air enclosed in the power distribution panel may condense into water droplets, causing a small flood inside the power distribution panel, thereby losing its normal ignition function.
一旦发现是因为点火系统的潮湿而造成点火不良、发动机性能下降的话，建议先用干燥的纸巾或干布把分电盘内外及电线等擦干，然后用专用干燥剂喷罐将干燥剂喷在分电盘盖、电瓶接头、火花塞、高压线及点火线圈等处，等一阵后就可启动发动机了。
If it is found that the ignition system is wet and causing poor ignition or engine performance degradation, it is recommended to use a dry paper towel or cloth to wipe the inside and outside of the power distribution panel, as well as electrical wires, and then use a dedicated desiccant spray tank to spray desiccant onto the power distribution panel cover, battery connector, spark plug, high-voltage wire, and ignition coil. After a while, the engine can be started.
制动除水
Brake water removal
轿车制动系统绝大多数是双管路真空助力液压制动，值得重视的是，传递制动力的制动液具有很强的吸水性。如果有水进入制动液，在制动的过程中，摩擦产生的高温会使水气化。而气体具有可压缩性，在制动液中被压缩，就会造成制动失灵甚至失效。
The vast majority of car braking systems use dual pipe vacuum assisted hydraulic braking. It is worth noting that the brake fluid that transmits braking force has a strong water absorption property. If water enters the brake fluid, the high temperature generated by friction during braking can cause the water to vaporize. The gas has compressibility, and if compressed in the brake fluid, it can cause brake failure or even failure.
雨水多时，空气的湿度会越来越大，如果制动液在雨季到来之前就有少量水分，那将是很危险的。有些制动液吸水较严重的车辆，在制动液油杯盖上就能看见水珠。所以在保养时必须要检查制动液，以保证驾乘者的生命安全。
When there is a lot of rain, the humidity of the air will become higher and higher. If the brake fluid has a small amount of moisture before the rainy season arrives, it will be very dangerous. Some vehicles with severe brake fluid absorption can see water droplets on the brake fluid cup cover. Therefore, during maintenance, it is necessary to check the brake fluid to ensure the safety of drivers and passengers.
Note: When encountering heavy rain, the vehicle should be cleaned promptly after returning, otherwise it may cause sludge to accumulate in the gap under the vehicle, which is where moisture can be hidden and is also prone to rust.
