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.
It is considered that vehicle urea is agricultural urea
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.
Vehicle urea water
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!
Thinks that vehicle urea will increase fuel consumption
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.
Thinks inferior urea for vehicles is cheap
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.
I believe you have a deeper understanding of the use of vehicle urea in mixer trucks. I hope this knowledge can bring you more help. For more information about mixer equipment, you can follow our website www.zkzdsljbc Com consulting!
