汽車作為經(jīng)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(jì)南寶馬汽車專修廠家就來講講寶馬汽車點(diǎn)火啟動(dòng)與制動(dòng)除水的事項(xiàng)！

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(diǎn)火啟動(dòng)

Ignition start

雨天，車主經(jīng)常會(huì)碰到發(fā)動(dòng)機(jī)不易啟動(dòng)的毛病，有時(shí)即使勉強(qiáng)啟動(dòng)起來，也是有氣無力的。這種毛病大的可能是出自點(diǎn)火系統(tǒng)因潮濕而產(chǎn)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(nèi)的熱空氣就有可能凝結(jié)成水滴而造成分電盤內(nèi)部的小水災(zāi)，因而喪失了正常的點(diǎn)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(fā)現(xiàn)是因?yàn)辄c(diǎn)火系統(tǒng)的潮濕而造成點(diǎn)火不良、發(fā)動(dòng)機(jī)性能下降的話，建議先用干燥的紙巾或干布把分電盤內(nèi)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(diǎn)火線圈等處，等一陣后就可啟動(dòng)發(fā)動(dòng)機(jī)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(dòng)除水

Brake water removal

轎車制動(dòng)系統(tǒng)絕大多數(shù)是雙管路真空助力液壓制動(dòng)，值得重視的是，傳遞制動(dòng)力的制動(dòng)液具有很強(qiáng)的吸水性。如果有水進(jìn)入制動(dòng)液，在制動(dòng)的過程中，摩擦產(chǎn)生的高溫會(huì)使水氣化。而氣體具有可壓縮性，在制動(dòng)液中被壓縮，就會(huì)造成制動(dòng)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(shí)，空氣的濕度會(huì)越來越大，如果制動(dòng)液在雨季到來之前就有少量水分，那將是很危險(xiǎn)的。有些制動(dòng)液吸水較嚴(yán)重的車輛，在制動(dòng)液油杯蓋上就能看見水珠。所以在保養(yǎng)時(shí)必須要檢查制動(dòng)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.

注意，遇到大雨天氣時(shí)，車子返回后應(yīng)進(jìn)行及時(shí)清洗，否則可導(dǎo)致車輛下側(cè)的空隙處積存污泥，這就是濕氣得以藏匿的地方，也是容易導(dǎo)致生銹的地方。更多事項(xiàng)就來我們網(wǎng)站http://www.fmghkd.cn咨詢吧！

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.
