During the operation of the engine of the automatic concrete mixer, the exhaust pipe sometimes discharges water, especially in winter, which makes people mistakenly believe that the cooling system of the mixer is poor and there is a leakage problem. In fact, this is a very normal physical phenomenon and a manifestation of full combustion of gasoline.

汽油燃烧后主要产生二氧化碳、水和少量一氧化碳,每1千克汽油与空气混合燃烧后产生约会1.42千克的水,主要以汽态的形式排入大气。由于主消音器位于车的后部,温度相对较低,里面为多腔室结构,容易形成积水,搅拌车发动机高速运行时里面的积水在气流的作用下会被排出,即常见的喷水现象。经常在拥堵路面低速行驶的车辆,特别在冬季消音器积水现象会略严重。

Gasoline combustion mainly produces carbon dioxide, water and a small amount of carbon monoxide. Every 1kg of gasoline is mixed with air to produce about 1.42kg of water, which is mainly discharged into the atmosphere in the form of vapor. As the main muffler is located at the rear of the vehicle, the temperature is relatively low, and it is a multi chamber structure, which is easy to form ponding. When the mixer engine runs at high speed, the ponding in the mixer will be discharged under the action of air flow, that is, a common water spraying phenomenon. For vehicles that often drive at low speed on congested roads, especially in winter, the phenomenon of ponding on the muffler will be slightly serious.

如燃油内硫的含量超标,搅拌车发动机燃烧后会产生硫的氧化物,与水一起积聚在里面易导致消音器腐蚀穿孔。将车停在上坡道上,原地轰一轰油门有助于积水的排出,可以延长消音器的使用寿命。

If the sulfur content in the fuel exceeds the standard, sulfur oxides will be produced after the combustion of the mixer engine, which will accumulate in it together with water, which is easy to cause corrosion and perforation of the muffler. Park the car on the ramp and blow the accelerator in place, which helps to drain the accumulated water and prolong the service life of the muffler.

自动混凝土搅拌机建议,如果广大司机不放心,可到就近的搅拌车服务中心进行检查和维护,以保证搅拌车车况维持在良好水平。

Experts of automatic concrete mixer suggest that if the majority of drivers are not at ease, they can go to the nearest mixer Service Center for inspection and maintenance to ensure that the condition of the mixer is maintained at a good level.
