如今看來，攪拌車的排放要達標離不開車用尿素，下面我們就來談一談攪拌車使用車用尿素的誤區有什么，了解充分才能讓好攪拌車的使用更加順利。

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.

認為車用尿素是農用尿素

It is considered that vehicle urea is agricultural urea

很多人認為車用尿素和農用尿素是一樣的，混用也可以，但這種想法是錯誤的。由于車用尿素的配比要求嚴格，一般由32.5%的高純尿素和67.5%的去離子水組成，而農用尿素則含有大量顆粒物、金屬離子、礦物質等雜質。如果混凝土攪拌車使用農用尿素，SCR系統反應后會產生一系列雜質，對SCR系統造成致命傷害，直接后果就是更換SCR后處理系統。

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.

車用尿素加水

Vehicle urea water

有人說我不用農用尿素，所以加水也沒壞處。這是一個大錯誤。要知道，水中也含有雜質，而這些雜質很容易形成固體，從而導致柴油機尾氣處理液的噴嘴堵塞。對SCR系統的損害是不可逆的！

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!

認為車用尿素會增加油耗

Thinks that vehicle urea will increase fuel consumption

部分攪拌車用戶會通過屏蔽柴油尾氣處理液來降低油耗，從而降低購買柴油尾氣處理液的成本以節省資金。這種認識是錯誤的。事實上，SCR系統不參與攪拌車的傳動和油的燃燒，反而會增加SCR系統的油耗。因為如果SCR系統出現故障，會導致發動機扭矩限制，從而增加燃油量。

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.

認為車用劣質尿素便宜

Thinks inferior urea for vehicles is cheap

很多混凝土攪拌車司機為了省錢而用便宜的尿素車用，覺得沒關系，只要加了就行。通過更換去離子水，用普通水生產的不合格車用尿素含有大量超標雜質。長期使用會造成過濾器堵塞，降低SCR系統的霧化效果，甚會因雜質過多而損壞尿素泵。

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.
