如今看来，搅拌车的排放要达标离不开车用尿素，下面我们就来谈一谈搅拌车使用车用尿素的误区有什么，了解充分才能让好搅拌车的使用更加顺利。
Now, it seems that the emission of the mixer truck can not reach the standard without the use of urea for driving. Now let's talk about the misunderstanding of the use of urea for the mixer truck. Only with a full understanding can we make the use of the mixer truck more safe and smooth.
认为车用尿素是农用尿素
It is considered that vehicle urea is agricultural urea
很多人认为车用尿素和农用尿素是一样的，混用也可以，但这种想法是错误的。由于车用尿素的配比要求严格，一般由32.5%的高纯尿素和67.5%的去离子水组成，而农用尿素则含有大量颗粒物、金属离子、矿物质等杂质。如果混凝土搅拌车使用农用尿素，SCR系统反应后会产生一系列杂质，对SCR系统造成致命伤害，直接后果就是更换SCR后处理系统。
Many people think that automotive urea and agricultural urea are the same, and it is OK to mix them, but this idea is wrong. Due to the strict requirements for the proportion of vehicle urea, it is generally composed of 32.5% high-purity urea and 67.5% deionized water, while agricultural urea contains a large number of particles, metal ions, minerals and other impurities. If the concrete mixer uses agricultural urea, a series of impurities will be generated after the SCR system reacts, causing fatal damage to the SCR system. The direct consequence is to replace the SCR post-treatment system.
车用尿素加水
Vehicle urea water
有人说我不用农用尿素，所以加水也没坏处。这是一个大错误。要知道，水中也含有杂质，而这些杂质很容易形成固体，从而导致柴油机尾气处理液的喷嘴堵塞。对SCR系统的损害是不可逆的！
Some people say that I do not use agricultural urea, so adding water is not harmful. This is a big mistake. You should know that the water also contains impurities, which are easy to form solids, resulting in blockage of the nozzle of diesel engine exhaust treatment fluid. Damage to SCR system is irreversible!
认为车用尿素会增加油耗
Thinks that vehicle urea will increase fuel consumption
部分搅拌车用户会通过屏蔽柴油尾气处理液来降低油耗，从而降低购买柴油尾气处理液的成本以节省资金。这种认识是错误的。事实上，SCR系统不参与搅拌车的传动和油的燃烧，反而会增加SCR系统的油耗。因为如果SCR系统出现故障，会导致发动机扭矩限制，从而增加燃油量。
Some mixer truck users will reduce fuel consumption by shielding diesel exhaust treatment fluid, so as to reduce the cost of purchasing diesel exhaust treatment fluid and save money. This understanding is wrong. In fact, SCR system does not participate in the transmission of mixer truck and oil combustion, but will increase the oil consumption of SCR system. Because if the SCR system fails, the engine torque will be limited, which will increase the fuel volume.
认为车用劣质尿素便宜
Thinks inferior urea for vehicles is cheap
很多混凝土搅拌车司机为了省钱而用便宜的尿素车用，觉得没关系，只要加了就行。通过更换去离子水，用普通水生产的不合格车用尿素含有大量超标杂质。长期使用会造成过滤器堵塞，降低SCR系统的雾化效果，甚会因杂质过多而损坏尿素泵。
Many concrete mixer drivers use cheap urea to save money. They think it doesn't matter. Just add it. Through the replacement of deionized water, the unqualified vehicle urea produced with ordinary water contains a large amount of excessive impurities. Long term use will cause filter blockage, reduce the atomization effect of SCR system, and even damage the urea pump due to excessive impurities.
