Some customers encounter a problem when using the concrete mixer. Sometimes, due to personal negligence, they don't pay attention to the fact that the urea in the urea tank has been used up and they don't know what to do. If there is no urea in the mixer urea tank, can you continue to start up? Why? Let me tell you something. First of all, the answer is No. if there is no urea in the mixer urea tank, you can't continue to drive. Car owners should bear this in mind. The specific analysis is as follows:

混凝土攪拌機(jī)實(shí)施的國(guó)四、歐四排放標(biāo)準(zhǔn)柴油機(jī)減排系統(tǒng)中需用到尿素水溶液，該尿素罐用于儲(chǔ)存尿素水溶液，SCR選擇性還原，降低氮氧化物。

The urea water solution is needed in the diesel engine emission reduction system of the fourth national and fourth European emission standards for concrete mixer. The urea tank is used to store urea water solution, SCR selective reduction and reduce nitrogen oxides.
           

由于尿素的消耗量比較低，滿(mǎn)足歐IV標(biāo)準(zhǔn)的消耗量大約是燃油消耗的3.5%，滿(mǎn)足歐V標(biāo)準(zhǔn)大約是燃油消耗的5%。當(dāng)尿素罐內(nèi)沒(méi)有尿素后，發(fā)動(dòng)機(jī)的排放就不會(huì)達(dá)標(biāo)，車(chē)輛的自動(dòng)診斷系統(tǒng)也會(huì)報(bào)警，提醒司機(jī)及時(shí)添加。這個(gè)時(shí)候如果繼續(xù)開(kāi)車(chē)，不加尿素會(huì)冒白煙，發(fā)動(dòng)機(jī)檢測(cè)你的尾氣不達(dá)標(biāo)，會(huì)限扭，就是不夠力，限制發(fā)動(dòng)機(jī)20%動(dòng)力，然后進(jìn)一步會(huì)鎖死發(fā)動(dòng)機(jī)，對(duì)發(fā)動(dòng)機(jī)會(huì)有損害。

Due to the low consumption of urea, the consumption meeting Euro IV standard is about 3.5% of fuel consumption, and the consumption meeting Euro V standard is about 5% of fuel consumption. When there is no urea in the urea tank, the emission of the engine will not meet the standard, and the automatic diagnosis system of the vehicle will also give an alarm to remind the driver to add it in time. If you continue to drive at this time, if you don't add urea, you will emit white smoke. If your exhaust gas is not up to standard in the engine test, you will limit the torque, that is, it's not strong enough. Limit 20% of the power of the engine, and then further lock the engine, which will cause damage to the engine.

所以，為避免尿素罐里的尿素欠缺，車(chē)主朋友們應(yīng)該及時(shí)檢查，保障發(fā)動(dòng)機(jī)的正常運(yùn)轉(zhuǎn)，千萬(wàn)不要在沒(méi)有尿素的情況下繼續(xù)行駛，車(chē)中盡量備一桶備用尿素液，以防攪拌機(jī)中途沒(méi)尿素液了堵塞尿素管。

Therefore, in order to avoid the lack of urea in the urea tank, car owners should check in time to ensure the normal operation of the engine. Never drive without urea. Try to prepare a bucket of spare urea liquid in the car to prevent the mixer from blocking the urea pipe when there is no urea liquid in the middle.
