搅拌车使用车用尿素的原因

Reasons for using vehicle urea in mixer truck

1、要知道加车用的尿素是针对柴油机的车辆，搅拌车大多使用柴油机。因为柴油机会排放有害气体氮氧化物，会造成环境污染。人体长期吸入这种废气会对人体造成极大伤害。为了减少这种危害，使用柴油机的搅拌车应添加车用尿素。车用尿素添加有催化作用。发生化学反应，将氮氧化物转化为待排放的氮气和水。

1. You should know that the urea used for loading is for diesel vehicles, and most mixer vehicles use diesel engines. Because diesel will emit harmful gas nitrogen oxides, which will cause environmental pollution. Long term inhalation of this waste gas will cause great harm to human body. In order to reduce this hazard, truck urea should be added to the mixer truck with diesel engine. The addition of vehicle urea has a catalytic effect. Chemical reaction occurs to convert nitrogen oxides into nitrogen and water to be discharged.

2、自动上料搅拌车排放达标离不开车用尿素。车用尿素是一种柴油车尾气处理液。车用尿素主要用于吸收柴油车尾气中的氮氧化物，也是SCR工作过程中的关键环节。

2. Urea for start-up is indispensable for the automatic feeding mixer to reach the emission standard. Vehicle urea is a kind of diesel vehicle exhaust treatment fluid. Vehicle urea is mainly used to absorb nitrogen oxides in diesel vehicle exhaust, and it is also a key link in the working process of SCR.

3、车用尿素对车辆的动力和油耗起着关键作用。如果不给车加尿素，或者使用纯度不够、质量差的尿素溶液，都会导致发动机自动减速。同时，劣质车用尿素会污染SCR催化反应罐中的催化剂，造成后处理系统部件的损坏。您知道，后处理系统的维护成本可能相当昂贵。这种做法不仅增加了对环境的破坏，也增加了搅拌车的使用成本。

3. Vehicle urea plays a key role in vehicle power and fuel consumption. If urea is not added to the vehicle, or urea solution with insufficient purity and poor quality is used, the engine will slow down automatically. At the same time, inferior automotive urea will pollute the catalyst in the SCR catalytic reaction tank and cause damage to the components of the aftertreatment system. As you know, the maintenance cost of the aftertreatment system can be quite expensive. This practice not only increases the damage to the environment, but also increases the use cost of the mixer.

搅拌车使用尿素的误区

Misunderstanding of using urea in mixer truck

很多人认为车用尿素和农用尿素是一样的，混用也可以，但这种想法是错误的。由于车用尿素的配比要求严格，一般由32.5%的高纯尿素和67.5%的去离子水组成，而农用尿素则含有大量颗粒物、金属离子、矿物质等杂质。如果混凝土搅拌车使用农用尿素，SCR系统反应后会产生一系列杂质，对SCR系统造成致命伤害，直接后果就是更换SCR后处理系统。

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.

有人说我不用农用尿素，所以加水也没坏处。这是一个大错误。要知道，水中也含有杂质，而这些杂质很容易形成固体，从而导致柴油机尾气处理液的喷嘴堵塞。对SCR系统的损害是不可逆的！

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!

部分自动上料搅拌车用户会通过屏蔽柴油尾气处理液来降低油耗，从而降低购买柴油尾气处理液的成本以节省资金。这种认识是错误的。事实上，SCR系统不参与搅拌车的传动和油的燃烧，反而会增加SCR系统的油耗。因为如果SCR系统出现故障，会导致发动机扭矩限制，从而增加燃油量。

Some users of automatic loading mixer will reduce fuel consumption by shielding diesel exhaust treatment liquid, so as to reduce the cost of purchasing diesel exhaust treatment liquid 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.

很多司机为了省钱而用便宜的尿素车用，觉得没关系，只要加了就行。通过更换去离子水，用普通水生产的不合格车用尿素含有很多超标杂质。长期使用会造成过滤器堵塞，降低SCR系统的雾化效果，甚会因杂质过多而损坏尿素。泵。

Many drivers use cheap urea to save money. They think it doesn't matter. Just add it. By replacing deionized water, the unqualified vehicle urea produced with ordinary water contains many excessive impurities. Long term use will cause filter blockage, reduce the atomization effect of SCR system, and even damage urea due to excessive impurities. Pump.
