冬季排气管冒白烟正常吗?

来源:http://www.lutongqixiu.com/ 日期:2023-06-20 发布人:admin
冬季车辆启动后,排气管都会冒出一团一团的白烟。大家都冒烟,我也冒烟,正常!不不不,冒白烟也分情况。下面济南奔驰汽车维修人员为你着重分析分析:
After starting the vehicle in winter, the exhaust pipe emits white smoke in clumps. Everyone is smoking, and I am also smoking, normal! No, no, no, white smoke varies depending on the situation. Below, Jinan Mercedes Benz automotive maintenance personnel will focus on analyzing and analyzing for you:
水汽白烟
Water vapor white smoke
汽油燃烧后会生成水,水在发动机运行时的高温状态下变成水蒸气,通过排气系统到达排气管尾部时,热乎乎的水蒸气看起来就像一团一团的白烟。有的汽车为了静音和回压,排气管做得比较长,不仅冒白烟,还会伴随着滴水。这种情况是正常的,不用担心。
After the combustion of gasoline, water is generated, which becomes water vapor during the high temperature state of engine operation. When it reaches the tail of the exhaust pipe through the exhaust system, the hot water vapor looks like clusters of white smoke. Some cars have longer exhaust pipes for noise reduction and pressure reduction, which not only emit white smoke but also accompanied by dripping water. This situation is normal, don't worry.
油气白烟
Oil gas white smoke
缸内混合气不完全燃烧时,也会从排气管冒出一团一团的白烟,这时候,问题就比较严重了。混合气不完全燃烧时冒出的是油气白烟,部分燃油通过排气管排出,造成浪费不说,还会污染三元催化器。同时,不完全燃烧还会导致发动机内部严重积碳,甚至在缸内造成爆燃,损伤气缸内壁,影响发动机寿命。
When the mixture in the cylinder is not fully burned, white smoke will also emit in clusters from the exhaust pipe, and at this point, the problem becomes more serious. When the mixture is not fully burned, it emits white smoke from the fuel gas, and some of the fuel is discharged through the exhaust pipe, causing waste and polluting the three-way catalytic converter. At the same time, incomplete combustion can also lead to severe carbon deposition inside the engine, and even cause detonation in the cylinder, damaging the inner wall of the cylinder, and affecting the engine's lifespan.
冬季汽车的排气管会冒白烟还向外滴水。有的车不冒白烟,说明其发动机排量属于小排量发动机或者低转速时不冒,要不就是排气管漏气或者有轻微堵塞现象。
In winter, the exhaust pipe of a car emits white smoke and drips water outwards. Some cars do not emit white smoke, indicating that their engine displacement belongs to a small displacement engine or does not emit smoke at low revs, or there is air leakage or slight blockage in the exhaust pipe.

冒白烟是因为汽油完全燃烧后生成的是水和二氧化碳,水在高温下是水蒸汽,水蒸气在高温下是无色透明的,但是当温度低于100℃以后,水蒸气就会冷凝成水,如果冷凝的水滴很小并且悬浮在空气中,水蒸气就呈现为白色的气体,环境气温较低时,排气管冒白烟就是水蒸气。
The white smoke is caused by the generation of water and carbon dioxide after the complete combustion of gasoline. Water is steam at high temperature, which is colorless and transparent at high temperature. However, when the temperature is lower than 100 ℃, the water vapor will condense into water. If the condensed water drops are very small and suspended in the air, the water vapor will appear as white gas. When the ambient temperature is low, the white smoke from the exhaust pipe is water vapor.
如果冷凝的水滴积聚起来,就变成了水。排气管排出的水滴,就是汽油燃烧后生成的水蒸气,在排气管和消音器中冷凝的结果,只不过当环境气温较高时,水蒸气还没有冷凝就已经排出去了,当环境温度较低时,水蒸气就会在排气管壁冷凝成水滴,并且随排气流出来了。这种现象在发动机工作情况较好的车上是普遍存在的。
If condensed water droplets accumulate, they become water. The water droplets discharged from the exhaust pipe are the result of condensation of water vapor generated after gasoline combustion in the exhaust pipe and muffler. However, when the ambient temperature is high, the water vapor has already been discharged before condensation. When the ambient temperature is low, the water vapor will condense into water droplets on the exhaust pipe wall and flow out with the exhaust. This phenomenon is common in vehicles with good engine operation.
如果排气管冒出的白烟带有很明显的汽油味,那得千万注意了,混合气燃烧效率亟待提升!更多相关事项就来我们网站http://www.lutongqixiu.com咨询!
If the white smoke emitted from the exhaust pipe has a clear gasoline smell, it is important to pay attention, as the combustion efficiency of the mixture urgently needs to be improved! For more related matters, come to our website http://www.lutongqixiu.com consulting service
