車(chē)用尿素就是自動(dòng)上料攪拌機(jī)尾氣處理液，主要用于吸收自動(dòng)上料攪拌機(jī)尾氣中的氮氧化物，在攪拌車(chē)、隨車(chē)吊中十分常見(jiàn)。關(guān)于車(chē)用尿素經(jīng)常存在一些認(rèn)知誤區(qū)，下面來(lái)講講吧。

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.

誤區(qū)一：車(chē)用尿素就是農(nóng)用尿素

Myth 1: Vehicle urea is agricultural urea

很多人認(rèn)為車(chē)用尿素和農(nóng)用尿素是一樣的，混著用是可以的，這種想法是錯(cuò)誤的，車(chē)用尿素的配比是有嚴(yán)格要求的，一般是由32.5%高純尿素和67.5%的去離子的水組成，而農(nóng)用尿素的顆粒物、金屬離子、礦物質(zhì)等雜質(zhì)非常多，如果混凝土攪拌車(chē)使用農(nóng)用尿素，經(jīng)過(guò)SCR系統(tǒng)反應(yīng)一系列雜質(zhì)，會(huì)對(duì)SCR系統(tǒng)造成致命的損傷，直接后果就是更換SCR后處理系統(tǒng)，那就得不償失了。

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.

誤區(qū)二：柴油尾氣處理液加水

Myth 2: adding water to diesel tail gas treatment liquid

有人說(shuō)，我不使用農(nóng)用尿素，加水總沒(méi)有什么害處吧，這你就大錯(cuò)特錯(cuò)了，要知道水中也是含有雜質(zhì)的，而這些雜質(zhì)很容易形成固體物，從而導(dǎo)致尾氣處理液噴嘴堵塞，這對(duì)SCR系統(tǒng)的傷害是不可逆轉(zhuǎn)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.

誤區(qū)三：加柴油尾氣處理液會(huì)增加油耗

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

一些專(zhuān)用車(chē)使用者會(huì)通過(guò)屏蔽柴油尾氣處理液來(lái)減少其油耗，從而縮減購(gòu)買(mǎi)柴油尾氣處理液的費(fèi)用，以此來(lái)節(jié)省開(kāi)支。這種認(rèn)知是錯(cuò)誤的，其實(shí)SCR系統(tǒng)是完全不參與攪拌車(chē)的傳動(dòng)和油的燃燒的，反而會(huì)促使SCR系統(tǒng)增加油耗是因?yàn)镾CR系統(tǒng)出現(xiàn)故障，從而導(dǎo)致發(fā)動(dòng)機(jī)限扭，進(jìn)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.

誤區(qū)四：劣質(zhì)柴油尾氣處理液實(shí)惠無(wú)害

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

柴油尾氣處理液本身價(jià)格不高，和劣質(zhì)的之間的差別不大，很多司機(jī)為了省錢(qián)使用廉價(jià)的柴油尾氣處理液，覺(jué)得無(wú)所謂，有加就行。代替去離子水而使用普通水生產(chǎn)出的不合格柴油尾氣處理液中含有很多超標(biāo)的雜質(zhì)，長(zhǎng)期使用，會(huì)導(dǎo)致濾清器堵塞，柴油尾氣處理液輸送管道和噴嘴，降低SCR系統(tǒng)霧化效果，雜質(zhì)過(guò)多甚會(huì)損壞尿素泵。

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.
