Shenzhen car with water urea solution, urea water Shenzhen Car

Shenzhen car with urea solution of water, Shenzhen car with urea for agricultural urea water could easily lead poisoning is not a substitute vehicle catalytic converters with urea solution is stable concentration urea solution (by the 32.5% high purity urea and 67.5% of deionized water). used to restore the automobile combustion exhaust nitrogen oxides. Ordinary fertilizers containing urea as biuret, mechanical impurities, formaldehyde, metal ions cause catalyst poisoning SCR exhaust processor, damage components. And we search through the network, found that the value of small urea pump 1 million, if the damage can not be undone occurs, the user is not a small loss. Moreover, because the low temperature and crystallization of urea fertilizer and urea concentration can not be guaranteed, will result in the conversion of nitrogen oxides is low. Further loss of ammonia will destroy SCR system, so that the vehicle can not meet emission standards. Water was added to replace urea environmental pollution - one of the four countries of cheating is common practice for the boycott, bypassing the OBD monitoring, water instead of urea solution, ensure that the engine is working properly. Because the country four SCR route engine combustion, NOx emission content is relatively high. NOx conversion in the air to produce water-binding nitrate is a major contributor to acid rain. While NOx and other pollutants will photochemical smog pollution in ultraviolet rays. Great harm to the atmosphere, and thus also have a great impact on human health. Thus, the behavior of urea water replacement should be negative and resisted. Car choice Car urea solution of urea in the country a lot of nicknames, according to the European name for the "Adblue" solution, while in North America, also known as Diesel Exhaust Fluid DEF, China also has called diesel engine NOx reducing agent, car with denitration agent. Most manufacturers tend to use diesel concentration of 32.5% aqueous urea solution (AUS32) as the concentration of the reducing agent, urea crystallization point directly affects the rate of reduction of nitrogen oxides and urea solution. Too high or too low a concentration of not only fail to improve the conversion efficiency of nitrogen oxides, but will result in the formation of ammonia remaining secondary pollution. And the choice of 32.5% of the concentration, because the vehicle urea solution at this concentration the lowest point of crystallization (freezing point -11 ℃).
