说起车用尿素,大家可能会有些陌生,不了解的人自然也是不了解,今天小编给大家说一说车用尿素的用处,使用车用尿素可以减少氮氧化合物的排放,给我们的大气减少了污染,在众多柴油车尾气排放中车用尿素的表现更明显更出众。

When it comes to vehicle urea, you may be a little strange, and those who don't know it naturally don't understand it. Today, I'd like to tell you about the use of vehicle urea. Using vehicle urea can reduce the emission of nitrogen oxides and reduce the pollution of our atmosphere. Among the exhaust emissions of many diesel vehicles, vehicle urea performs better.

车用尿素随着柴油车排放的推行,现在它的需求也是很大的。车的尾气从涡轮出来后进入排气管,排气管上安装有尿素计量喷射装置,喷入尿素水溶液,尿素溶液和尾气中的氮氧化合物在SCR反应罐中发生氧化还原反应,生成氮气和水排出。

With the implementation of diesel vehicle emission, the demand for vehicle urea is also great. The exhaust gas of the vehicle comes out of the turbine and enters into the exhaust pipe. A urea metering injection device is installed on the exhaust pipe to inject urea water solution. The oxidation-reduction reaction between urea solution and nitrogen oxides in the exhaust gas takes place in the SCR reaction tank to generate nitrogen and water for discharge.

汽车尾气中的氮氧化合物不仅是酸雨的成因之一,对人体也有直接的危害。车用尿素溶液的作用就是和汽车尾气中的氮氧化合物发生化学反应生成无毒的氮气和水,从而降低汽车尾气中有毒气体的排放,减少了污染。

Nitrogen oxides in automobile exhaust are not only one of the causes of acid rain, but also directly harmful to human body. The function of vehicle urea solution is to produce nontoxic nitrogen and water by chemical reaction with nitrogen oxides in vehicle exhaust, so as to reduce the emission of toxic gases in vehicle exhaust and reduce pollution.

柴油机尾气处理液质量是劣质的或者是纯度不够的情况下,会发生车辆发动机自动减速。同时,质量伪劣的柴油机尾气处理液会污染SCR催化反应罐中的催化剂,造成严重后果。所以提倡大家使用车用尿素,给我们的环境减少了大量的污染。

When the quality of diesel exhaust treatment fluid is poor or the purity is not enough, the vehicle engine will decelerate automatically. At the same time, the quality of diesel exhaust treatment fluid will pollute the catalyst in SCR catalytic reaction tank, causing serious consequences. So we advocate the use of vehicle urea, to our environment to reduce a lot of pollution.
