It is a good phenomenon that the exhaust pipe drips water. Generally speaking, the exhaust of the exhaust pipe can show the combustion of the engine. There are three kinds:

　　種是水蒸氣噴出來就揮發，會噴水就是水蒸氣在排氣管里凝結成水滴才會噴出水來。

　　The first is that water vapor evaporates when it comes out. It sprays water when it condenses into droplets in the exhaust pipe.

　　第二種是黑煙一般會噴黑煙 就是有吃機油的狀況 要小心記的出門前檢查機油的存量等吃機油的狀況久了以后就會出現以下。

　　The second is that black smoke usually sprays black smoke, that is, the condition of eating oil should be carefully remembered before going out to check the oil stock and so on. After a long time, the condition of eating oil will appear below.

　　第三種狀況是排氣管出藍煙看到這種就要準備錢了因為你的引擎快掛了喔！

　　The third situation is that when you see the blue smoke coming out of the exhaust pipe, you have to prepare the money because your engine is hanging up.

　　排氣管會滴水，一般說法是引擎狀況好，這是正確的。當汽油跟空氣混合后點火燃燒排出水蒸氣，水蒸氣愈冷凝結變成水滴出來，代表著引擎裝況佳排氣管會滴水。并不是每一部車都會的，至少要有3個條件。

　　The exhaust pipe drips. Generally speaking, the engine is in good condition, which is correct. When gasoline is mixed with air, water vapor is discharged from ignition and combustion. The more condensation the vapor becomes, the more water drops out, which means that the exhaust pipe will drip when the engine is in good condition. Not every car will. There are at least three conditions.

　　1.汽油與空氣的混合比正確

　　1. The mixture ratio of gasoline and air is correct

　　2.引擎壓縮壓力高

　　2. High engine compression pressure

　　3.排氣溫度低

　　3. Low exhaust temperature

　　汽油與空氣的混合比正確，這表示你的供油系統狀況佳，不管是噴射供油還是化油器供油，混合的油氣剛好(這表示你的車子省油)。

　　The correct mixture ratio of gasoline and air means that your fuel supply system is in good condition, whether it's a fuel injection or a carburetor, and the mixture is just right (which means your car saves fuel).

　　引擎壓縮壓力高，壓縮壓力高這是代表著引擎狀況良好，汽缸還沒有磨損的現象。引擎一但有輕微吃黑油的狀況氣缸壓力就會變低.也會造成燃燒不完全，一但燃燒不完全就不會滴。

　　The high compression pressure and high compression pressure of the engine represent that the engine is in good condition and the cylinder is not worn out. Once the engine has a slight black oil intake, the cylinder pressure will be lower. It will also cause incomplete combustion, but incomplete combustion will not drip.

　　排氣溫度低，這表示你的點火正實正確，引擎內爆發的燃氣都集中在汽缸內只有少量或者根本沒有跑到排氣管內。要讓車子排氣管會滴水，需要引擎本身的條件.并不是每一部車子都有的，所以結論是排氣管會滴水就是引擎狀況很佳。

　　The low exhaust temperature means that your ignition is correct. The gas explosion in the engine is concentrated in the cylinder with only a small amount or not running into the exhaust pipe at all. In order to make the exhaust pipe drip water, it needs the condition of the engine itself. Not every car has it, so the conclusion is that the exhaust pipe drips water and the engine is in good condition.
