Recently, all parts of the country have entered the peak of the dry season. In some places, it rained for more than half a month, and the traveling companions will be soaked into chickens if they are not careful. The love car of the people with cars is the biggest test in a year. Whether to close the active start-stop system or not when wading in the water has also begun to trigger comments. So today, Xiaobian wants to talk with us about the active start-stop system when wading in the water. Do you want to be closed?

　　現(xiàn)在的轎車很多都裝備了發(fā)動機“主動啟停”功能，怒地就是讓發(fā)動機在擁堵的路況中“休息一會”，當(dāng)然也是為了省油環(huán)保，可是這項非常好的節(jié)油功能卻面臨著暴雨的“應(yīng)戰(zhàn)”，由于一不小心就會因而銷毀自己的愛車。

　　Now many cars are equipped with the engine "active start and stop" function, angrily is to let the engine in the congested road conditions "rest for a while", of course, is also to save fuel and environmental protection, but this very good fuel-saving function is facing the "battle" of the rainstorm, as a result of carelessness will be destroyed their car.

　　涉水時，為什么“主動啟停”能銷毀發(fā)動機

　　Why does "active start and stop" destroy the engine when wading

　　假定你地點的城市下了大暴雨，全市開端了“看海”形式，那么你的愛車就必須要面臨涉水的問題。當(dāng)然涉水有一定的深度，假如不至于導(dǎo)致進氣口進水，那也無所謂。不過不要忘了一般的司機看到前方積水越來越深，心里的那種懼怕會讓他收油踩剎車將車輛停住，主動啟停體系此時會認(rèn)為車輛需求短時間停止，當(dāng)然會主動將發(fā)動機熄滅。而這時分路面積水恰恰沒過進氣口，駕駛員抬起剎車踏板，發(fā)動時機主動發(fā)動，水就會從發(fā)動機進氣口抽入氣缸。發(fā)動機發(fā)動，水杯吸入氣缸，法定機瞬間也會宣告逝世！

　　Assuming that there is a heavy rain in your city and the whole city has begun to "see the sea", then your car must face the problem of wading water. Of course, there is a certain depth of wading, if it does not lead to intake water, it does not matter. Nevertheless, don't forget that the average driver sees that the water is getting deeper and deeper in front of him. The fear in his heart will make him take oil and brake to stop the vehicle. At this time, the active start-stop system will think that the vehicle needs to stop for a short time, and of course will actively extinguish the engine. At this time, the pavement water just did not pass the intake, the driver raised the brake pedal, initiative to start when the start time, water will be pumped into the cylinder from the engine intake. The engine starts, the water cup sucks in the cylinder, and the legal engine will be declared dead in an instant!

　　就算是水沒有沒過進氣口，還有一種狀況，涉水行走原本心里就有擔(dān)心，可是對面也有來車，水中狹路相逢，你降低車速，可人家不減速，你本能反響一腳剎車，主動啟罷工作了，結(jié)果滅車了，而此時涌起的水浪拍進了轎車的進氣口。驚魂未定的你下意識的抬起剎車，主動啟停又工作了，結(jié)果就悲催了。

　　Even if the water has not passed the air intake, there is still a situation, wading in the water would have been worried, but there is also a car across the water, narrow road encounter, you reduce the speed, but people do not slow down, you instinctively respond to a foot brake, actively start and stop work, the result of the car, and then the surge of water into the car's air inlet. You raise the brake unconsciously, start and stop actively and work again, and the result is sad.

　　為什么發(fā)動機進水再次發(fā)動會分分鐘報廢？

　　Why does it take minutes to scrap when the engine starts again?

　　現(xiàn)在轎車上廣泛使用的都是四沖程發(fā)動機，所謂四沖程就是“吸氣→緊縮→做工→排氣。其間的緊縮就是經(jīng)過活塞的運動，緊縮燃油與空氣的混合物，活塞上止點到下止點時的缸內(nèi)容積比，就是咱們常說的緊縮比，一個緊縮比是8的發(fā)動機就是空氣體積會被緊縮到本來的八分之一。

　　Nowadays, four-stroke engines are widely used in cars. The so-called four-stroke engines are "inspiration contraction workmanship exhaust". Compression is through the movement of the piston, the mixture of fuel and air, the ratio of cylinder volume from top dead point to bottom dead point of the piston, which is what we often call the compaction ratio. An engine with a compaction ratio of 8 is that the volume of air will be reduced to one eighth of its original volume.

　　可是假如是水進入氣缸，那就不容易被緊縮了，緊縮沖程時活塞和活塞連桿將會接受非常大的力氣，這很有可能會形成活塞連桿曲折甚至斷裂，而斷裂的活塞連桿極有可能會戳破氣缸。同時，水進入到氣缸還會形成機油乳化，因而機油簡直會喪失掉潤滑性，這對發(fā)動機而言也是無法接受的。

　　However, if water enters the cylinder, it is not easy to be tightened. During the tightening stroke, the piston and piston connecting rod will receive a great deal of force, which may cause the piston connecting rod to twist or even break, and the broken piston connecting rod will probably puncture the cylinder. At the same time, water into the cylinder will form oil emulsification, so the oil will almost lose lubricity, which is also unacceptable for the engine.

　　其實涉水時發(fā)動機主動發(fā)動，整個進程就像是咱們經(jīng)常說到的水中二次焚燒，結(jié)果小編不說小伙伴也可想而知了吧。

　　Actually, when wading, the engine starts on its own initiative. The whole process is like the second incineration in water, which we often talk about. As a result, Xiaobian can imagine it without talking about his companion.

　　發(fā)動機憋滅后怎么做？主動啟停還會工作嗎？

　　What to do when the engine is out? Will it work if it starts or stops on its own initiative?

　　涉水行進發(fā)動機被憋滅有兩種狀況，一種由于排氣阻力大，發(fā)動機排氣不暢被憋滅；還有一種是進氣體系進水后，發(fā)動機俄然沒有了空氣參加焚燒，導(dǎo)致瞬間熄火。小編在這兒想說，不管哪種狀況導(dǎo)致發(fā)動機熄火，都嚴(yán)禁直接發(fā)動發(fā)動機，此時首先要做的事檢查發(fā)動機進氣體系是否進水，其實就是檢查空氣濾是否被水漫過。

　　There are two kinds of conditions when the wading engine is blocked. One is that the engine exhaust is blocked due to the high exhaust resistance, and the other is that the engine suddenly loses air to participate in the combustion after the intake of the gas system. Xiaobian wants to say here that no matter what kind of condition causes the engine to stall, it is strictly forbidden to start the engine directly. At this time, the first thing to do is to check whether the air inlet system of the engine is filled with water. In fact, it is to check whether the air filter is overflowed by water.

　　假如空氣濾沒有水漫過，且空氣濾到節(jié)氣門的管道中也沒有水跡，就可以放心大膽的再次發(fā)動發(fā)動機了。假如空氣濾全部都被水濕透了，進氣管也有水跡，那么進氣支管也可能已經(jīng)進水了，可是發(fā)動機不一定會受損，這時分制止發(fā)動發(fā)動機，找拖車救援才是好的選擇。

　　If there is no water in the air filter and there is no water in the throttle pipe, you can start the engine again boldly. If all the air filters are wet through and the intake pipe has water marks, then the intake branch pipe may have already been water, but the engine may not be damaged. Stop starting the engine at this time, and find a trailer rescue is the best choice.

　　怎么判別車輛能否涉水？

　　How to judge whether a vehicle can wade?

　　看著一片汪洋雨水，要判別愛車能否涉水其實很簡單，就是以轎車輪胎為參照物，水的深度不到輪胎直徑的一半，就可以測驗涉水；假如水深到了輪胎直徑一半就要注意了，就是說假如水淹沒了半個輪胎那就別過了。假如是進入地道就要更謹(jǐn)慎了，一般地道墻壁會有涉水深度警示，可是假如是新手，心理素質(zhì)也不過硬，那就不要測驗涉水了。還有涉水的時分，車輛要勻速行進，堅持車距，特別要注意對方車輛行進過來形成的水浪。

　　Watching a vast ocean of rain, it is very simple to judge whether a car can wade in water, that is, using the car tire as a reference, the water depth is less than half of the diameter of the tire, you can test wading; if the water depth reaches half of the diameter of the tire, you should pay attention to it, that is, if the water floods half of the tire, that is to say, don't go. If you enter the tunnel, you should be more cautious. Generally, the tunnel wall will be warned of the depth of wading, but if you are a novice, your psychological quality is not too hard, then don't test wading. When wading, the vehicles should move at a uniform speed, stick to the distance, and pay special attention to the waves formed by the other side's vehicles.
