AdBlue DEF is a consumable that must be used in SCR technology. SCR technology uses a catalyst system can effectively reduced the emission of nitrogen oxides and solid particles produced by diesel engines into nitrogen and water.The main components of the SCR system include the catalyst, the AdBlue® injection unit, the urea tank and the AdBlue® dose controller. Process of SCR technol...
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 ...
If you have accidentally poured AdBlue® into your diesel tank, or just as likely, accidentally poured diesel into your AdBlue® tank. What should we do at this time? Luckily AdBlue® tanks are clearly marked with a BLUE cap, but accidents happen and if you do find yourself in the worst case scenario follow these tips. First thing - Don't start the engine If you turn the ignition on and s...
As the world's largest motor vehicle market, China's automotive AdBlue® market is rapidly opening. Relevant professionals predict that heavy diesel vehicles equipped with SCR systems will grow at least 500,000 vehicles a year, reaching 2.25 million by 2017. According to the diesel vehicle output calculation, it is expected that by the end of 2018, China's AdBlue® market capacity will reach...
In order to avoid contamination of automotive urea solutions and corrosion of containers, pipes, valves, connectors, gaskets, etc., it is necessary to ensure that the urea solution of the vehicle is compatible with the material in direct contact at all stages of handling, transportation, storage and sampling. Highly alloyed austenitic Cr-Ni-steels and Cr-Ni-Mo-steels, for example in accordance wit...
One aspect of a vehicle with SCR system is the need for replenishing Diesel Exhaust Fluid (DEF) on a periodic basis. DEF is carried in an onboard tank which must be periodically replenished by the operator based on vehicle operation. For light-duty vehicles, DEF refill intervals typically occur around the time of a recommended oil change, while DEF replenishment for heavy-duty vehicles and off-roa...
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 ...
It depends on many factors, includes the diesel engine size, driver, DEF system condition, presence of NOx in the exhaust stream. Typically, manufacturers refer to DEF consumption as a percentage or fuel consumption. This can vary from as low as 2% to as high as 10%. So if your engine consumes 100 gallons of fuel, for a 10% DEF consumption, it would have used 10 gallons of diesel exhaust fluid def...
