汽車作為經常在外面日曬雨淋的交通工具，自然非常容易在雨天受潮短路，為了延長汽車的使用壽命，也為了保證我們的行車安全，今天
濟南寶馬汽車專修廠家就來講講寶馬汽車點火啟動與制動除水的事項！
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!
點火啟動
Ignition start
雨天，車主經常會碰到發動機不易啟動的毛病，有時即使勉強啟動起來，也是有氣無力的。這種毛病大的可能是出自點火系統因潮濕而產生的漏電。此外，可能是一到下雨天氣變涼了，而封在分電盤內的熱空氣就有可能凝結成水滴而造成分電盤內部的小水災，因而喪失了正常的點火功能。
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.
一旦發現是因為點火系統的潮濕而造成點火不良、發動機性能下降的話，建議先用干燥的紙巾或干布把分電盤內外及電線等擦干，然后用專用干燥劑噴罐將干燥劑噴在分電盤蓋、電瓶接頭、火花塞、高壓線及點火線圈等處，等一陣后就可啟動發動機了。
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.
制動除水
Brake water removal
轎車制動系統絕大多數是雙管路真空助力液壓制動，值得重視的是，傳遞制動力的制動液具有很強的吸水性。如果有水進入制動液，在制動的過程中，摩擦產生的高溫會使水氣化。而氣體具有可壓縮性，在制動液中被壓縮，就會造成制動失靈甚至失效。
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.
雨水多時，空氣的濕度會越來越大，如果制動液在雨季到來之前就有少量水分，那將是很危險的。有些制動液吸水較嚴重的車輛，在制動液油杯蓋上就能看見水珠。所以在保養時必須要檢查制動液，以保證駕乘者的生命安全。
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.
