车用尿素就是自动上料搅拌机尾气处理液，主要用于吸收自动上料搅拌机尾气中的氮氧化物，在搅拌车、随车吊中十分常见。关于车用尿素经常存在一些认知误区，下面来讲讲吧。

Vehicle urea is the tail gas treatment liquid of the automatic feeding mixer, which is mainly used to absorb the nitrogen oxides in the tail gas of the automatic feeding mixer. It is very common in the mixer truck and the truck crane. There are often some cognitive misunderstandings about automotive urea. Let's talk about them below.

误区一：车用尿素就是农用尿素

Myth 1: Vehicle urea is agricultural urea

很多人认为车用尿素和农用尿素是一样的，混着用是可以的，这种想法是错误的，车用尿素的配比是有严格要求的，一般是由32.5%高纯尿素和67.5%的去离子的水组成，而农用尿素的颗粒物、金属离子、矿物质等杂质非常多，如果混凝土搅拌车使用农用尿素，经过SCR系统反应一系列杂质，会对SCR系统造成致命的损伤，直接后果就是更换SCR后处理系统，那就得不偿失了。

Many people think that vehicle urea and agricultural urea are the same, and mixed use is possible. This idea is wrong. There are strict requirements for the proportion of vehicle urea, which is generally composed of 32.5% high-purity urea and 67.5% deionized water. Agricultural urea contains many impurities such as particles, metal ions and minerals. If agricultural urea is used in concrete mixer, a series of impurities will be reacted by SCR system, It will cause fatal damage to the SCR system, and the direct consequence is to replace the SCR post-treatment system, which will outweigh the loss.

误区二：柴油尾气处理液加水

Myth 2: adding water to diesel tail gas treatment liquid

有人说，我不使用农用尿素，加水总没有什么害处吧，这你就大错特错了，要知道水中也是含有杂质的，而这些杂质很容易形成固体物，从而导致尾气处理液喷嘴堵塞，这对SCR系统的伤害是不可逆转的。

Some people say that I don't use agricultural urea, and there is no harm in adding water. This is a big mistake. You should know that the water also contains impurities, and these impurities are easy to form solids, which will lead to the blockage of the tail gas treatment liquid nozzle, and the damage to the SCR system is irreversible.

误区三：加柴油尾气处理液会增加油耗

Myth 3: adding diesel tail gas treatment liquid will increase fuel consumption

一些专用车使用者会通过屏蔽柴油尾气处理液来减少其油耗，从而缩减购买柴油尾气处理液的费用，以此来节省开支。这种认知是错误的，其实SCR系统是完全不参与搅拌车的传动和油的燃烧的，反而会促使SCR系统增加油耗是因为SCR系统出现故障，从而导致发动机限扭，进而增加了燃油量。

Some special vehicle users will reduce their fuel consumption by shielding the diesel exhaust treatment liquid, thus reducing the cost of purchasing the diesel exhaust treatment liquid, so as to save expenses. This understanding is wrong. In fact, the SCR system does not participate in the transmission of the mixer truck and the combustion of the oil at all. Instead, it will cause the SCR system to increase the fuel consumption because of the failure of the SCR system, which causes the engine to limit the torque and thus increases the fuel consumption.

误区四：劣质柴油尾气处理液实惠无害

Myth 4: low quality diesel exhaust gas treatment liquid is affordable and harmless

柴油尾气处理液本身价格不高，和劣质的之间的差别不大，很多司机为了省钱使用廉价的柴油尾气处理液，觉得无所谓，有加就行。代替去离子水而使用普通水生产出的不合格柴油尾气处理液中含有很多超标的杂质，长期使用，会导致滤清器堵塞，柴油尾气处理液输送管道和喷嘴，降低SCR系统雾化效果，杂质过多甚会损坏尿素泵。

The price of diesel exhaust gas treatment liquid is not high, and there is little difference between high-quality and low-quality diesel exhaust gas treatment liquid. Many drivers use cheap diesel exhaust gas treatment liquid to save money. They think it doesn't matter, just add it. The unqualified diesel tail gas treatment liquid produced by using ordinary water instead of deionized water contains many excessive impurities. Long term use will lead to filter blockage, diesel tail gas treatment liquid transmission pipeline and nozzle, reduce the atomization effect of SCR system, and excessive impurities may even damage the urea pump.
