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 ...
AdBlue® for vehicles is developed as the regulations for heavy-duty diesel vehicles are becoming more stringent. Particulate matter (PM) and nitrogen oxides (NOX) in diesel exhaust are the two main sources of vehicle exhaust pollution. For nitrogen oxides, the main exhaust aftertreatment technologies used in Europe and America are SCR and EGR+DPF, of which Europe and Japan is dominated by SCR,...
In general, some people will reduce the cost of purchasing AdBlue by shielding it . It is common to change the signal to deceive the driving computer by brushing the ECU or adding an emulator to the vehicle, so as to reduce the injection of AdBlue. Another cheaper way is to add a screw to the rear processor's sensor to enable the country's four vehicles to have less or no injection of AdBlue . It ...
EDI (Electrodeionization), also known as continuous electro-desalination technology, scientifically integrates electrodialysis technology and ion exchange technology. Through Selective permeation of cations and anions by cation and anion membranes and the exchange effect of ion exchange resin on ions in water.The directional migration of ions in water is realized under the action of electric ...
At present, two technical solutions are adopted to solve the problem of diesel exhaust emissions. One is SCR technology , another is EGR+DPF. Principle of EGR (Exhaust Gas Recirculation): The technology introduces engine exhaust gas into the intake pipe to reduces the oxygen concentration entering the cylinder and controls the combustion speed as well as lowers the combustion t...
- Functions of Exhaust Solution System 1. To ensure the best performance of the engine , combustion exhaust gas delivered to the engine safely at the same time ; 2. Reduce exhaust noise generated by the engine to meet the requirements of regulations and customers ; 3. Reduce or eliminate the pollutants generated by engine combustion in order to meet regulations and customer requirement . - T...
There have been two approaches to regulatory compliance: EGR and SCR. EGR was implemented January 1, 2007 and SCR was implemented January 1, 2010. EGR was able to meet the Federal Standards for 2007, but not able to meet the new standards for 2010. In 2007 the Emissions Standard was 1.2 NOx (g/hp.pr) and it could be reached using EGR technology, but January 1, 2010 this standard dropped to .02g/HP...
Nowadays, the environmental problem is highly concerned around the world. The problem of Global Warming, Greenhouse effect and Photochemical Smog are emphasized over 15 years, but it becomes worse and worse. Although the national solutions were announced, tragedies are never stop. As recently decades, the development of motor vehicle is growing rapidly. The traditional domestic car were ...
