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:

混凝土搅拌机实施的国四、欧四排放标准柴油机减排系统中需用到尿素水溶液，该尿素罐用于储存尿素水溶液，SCR选择性还原，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较低，满足欧IV标准的消耗量大约是燃油消耗的3.5%，满足欧V标准大约是燃油消耗的5%。当尿素罐内没有尿素后，发动机的排放就不会达标，车辆的自动诊断系统也会报警，提醒司机及时添加。这个时候如果继续开车，不加尿素会冒白烟，发动机检测你的尾气不达标，会限扭，就是不够力，限制发动机20%动力，然后进一步会锁死发动机，对发动机会有损害。

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，为避免尿素罐里的尿素欠缺，车主朋友们应该及时检查，保障发动机的正常运转，千万不要在没有尿素的情况下继续行驶，车中尽量备一桶备用尿素液，以防搅拌机中途没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.
