使用不合格车用尿素会对车辆造成影响吗?

首先,车用尿素溶液的浓度是影响SCR系统的关键因素之一。尿素浓度直接关系到氮氧化物的催化效率和尿素溶液的凝固点,而且也影响了后处理系统的参数设定,优质的车用尿素溶液的浓度必须在规定的范围之内,这是劣质产品难以实现的。

Firstly, the concentration of vehicle urea solution is one of the key factors affecting SCR system. The concentration of urea is directly related to the catalytic efficiency of nitrogen oxides and the freezing point of urea solution, and also affects the parameter setting of post-treatment system. The concentration of high-quality vehicle urea solution must be within the specified range, which is difficult to achieve for inferior products.

其次,车用尿素的质量对SCR系统喷雾附件、催化剂也会造成不良影响。不合格的车用尿素中存在不溶于水的杂质,堵塞滤清器、尿素溶液输送管道和喷嘴。杂质燃烧后产生的积炭,会影响后处理系统喷雾附件,对催化剂骨架进行堵塞,造成催化剂效率和使用寿命降低。

Secondly, the quality of vehicle urea also has adverse effects on spray attachment and catalyst of SCR system. There are water insoluble impurities in unqualified vehicle urea, which block the filter, urea solution pipeline and nozzle. The coke deposition after combustion of impurities will affect the spray attachment of the postprocessing system and block the catalyst skeleton, resulting in the reduction of catalyst efficiency and service life.

另外,尿素浓度不达标,将出现排放超标故障,体现为发动机扭矩立即降低,车辆动力不足;在寒冷工况下,会直接导致计量泵冻坏。

In addition, if the urea concentration is not up to the standard, the emission will exceed the standard, which is reflected in the reduction of engine torque immediately and the lack of vehicle power; in cold conditions, the metering pump will be directly frozen.

使用不合格车用尿素只是对车辆使用影响巨大,但是如果不添加车用尿素,那就是贻害子孙后代的缺德事了。很多人认为能省一点是一点,不添加车用尿素使用,貌似省了一点钱,实际上却是捡了芝麻丢了西瓜。现在就让液力源小编给您彻底分析一下,不添加车用尿素的危害!

The use of unqualified vehicle urea only has a great impact on the use of vehicles, but if you do not add vehicle urea, it is a bad thing to harm future generations. A lot of people think that saving a little is a little. It seems to save a little money if we don't add car urea. In fact, we have picked up sesame seeds and lost watermelon. Now let the hydraulic power source small make up for you to thoroughly analyze the harm of not adding vehicle urea!

目前很多车主通过骗过OBD监控,使得车辆对SCR系统中尿素耗尽不限功率,这样一来看似减少了很多麻烦,但是由于国五发动机为了降低PM排放而偏向充分燃烧,这样尾气中NOx排放不仅不会降低还会升高,尾气污染甚至超过国三车辆。

At present, many vehicle owners cheat the OBD monitoring to make the vehicle run out of power for the urea in the SCR system, which seems to reduce a lot of trouble. However, due to the full combustion of the national five engine in order to reduce PM emissions, the NOx emissions in the exhaust will not be reduced, but will also increase, and the exhaust pollution will even exceed that of the national three vehicles.

同时,SCR系统长期不工作会导致SCR系统内残留的车用尿素溶液结晶堵塞管道及喷嘴,又因为长期缺乏液体的浸泡使SCR系统各零部件的寿命降低甚至损坏,催化剂失去催化作用,更换SCR系统零部件的费用远远高于正常使用车用尿素的费用,反而加重车主的成本。

At the same time, the SCR system does not work for a long time, which will cause the residual urea solution in the SCR system to crystallize and block the pipes and nozzles. Because of the lack of liquid immersion for a long time, the service life of all parts of the SCR system will be reduced or even damaged, and the catalyst will lose its catalytic effect. The cost of replacing parts of the SCR system is far higher than that of normal use of vehicle urea, which will increase the cost of vehicle owners.
