The qualified AdBlue® is a high-purity transparent liquid composed of 32.5% high-purity urea and 67.5% deionized water. It has a light ammonia smell and is suitable for all Euro IV and Euro V emission diesel engine with SCR system. The fertilizer urea prilled will cause the catalyst poisoning and damage parts of SCR tail gas processors by its excessive biurea , mechanical impurities ...
Heavy goods vehicles – trucks, coaches and buses have been using SCR technology and AdBlue since 2004. For example, Mercedes and Volkswagen. The latest Euro VI emissions regulations from the European Commission has really driven an explosion in SCR technology from the passenger car perspective in Europe. The Euro VI regs introduced in 2014/15 demanded nitrogen oxides emissions should be reduced by...
China is one of the world's largest automobile production countries. In 2018, China's auto production and sales of 27.809 million and 28.881 million cars, of which heavy diesel vehicles accounted for about 18% of the production and sales. Heavy-duty diesel vehicles are the main source of pollutants emitted by motor vehicles. Therefore, the existence of a large number of heavy-duty diesel vehicles ...
According to the "Letter to the European Commission's Euro 7 Emissions Industry", it can be known that the Euro 7 emission standards require that the carbon monoxide emissions of tail gas be reduced from the current 500-1000 mg/km to 100-300 mg/km, while the nitrogen oxide emissions must be reduced to 30mg/km. Among them, the Euro VII emission proposal will force traditional fuel vehicles to be eq...
It is a particularly big misunderstanding, adding urea for vehicles will not increase fuel consumption. First understand the working principle of post-treatment. Basically, the exhaust gas comes out of the turbine and enters the exhaust pipe. A urea metering injection device is installed on the exhaust pipe, and the urea solution is sprayed. The urea solution and the nitrogen oxides in the ex...
Domestic AdBlue® is mainly purified from industrial urea, and its main principles are: 1) At a temperature of 70-75°C, urea is hydrolyzed in aqueous solution. 2) When the temperature is below 30°C, urea crystallizes out from the aqueous solution again. 3) With each hydrolysis and crystallization, its purity will be greatly improved. Generally, industrial grade urea is used for hydrolysis and c...
What vehicle need to be refilled with AdBlue® ? Heavy trucks, buses, tractor and all diesel vehicle with SCR system. The reason for adding AdBlue® is that the current diesel engine has higher combustion and greater torque than expected. That is to say, it can pull more and run faster with the same amount of oil than before, but the new nitrogen will appear after the AdBlue®...
