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...
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 ...
Nowadays, heavy diesel trucks come with the most current EPA compliant equipment. This equipment comes in the form of two different methods used in the after treatment of the exhaust emissions. These methods are Selective Catalytic Reduction (SCR) and Exhaust Gas Recirculation (EGR). Either are used to reduce NOx. In the early days, most trucks had only an EGR system with a diesel particulate filt...
The SCR exhaust after-treatment of the diesel engine is effective in controlling emissions of carbon monoxide (CO), hydrocarbons (HC) and particles (PM) in the exhaust gas to meeting the requirements of the regulations. Then the high content of nitrogen oxides (NOX) in the exhaust exhaust of the engine is treated by a special on-board aftertreatment system. At present, a variety of diesel exh...
With the increase of air pollution, especially haze weather, the tolerance of society to air pollution has reached its limit. Through long-term scientific investigation of the sources of air pollutants, it is found that the contribution rate of automobile exhaust to air pollution is more than 50%. Our diesel vehicles are still growing year by year, so the emission reduction of diesel vehicles is t...
A potential problem facing the consumers of AdBlue® is the issue of dilution. By definition, Diesel Exhaust Fluid or AdBlue®, is comprised of 32.5% urea and 67.5% deionised water. However, in order to obtain a greater mark up when selling AdBlue®, there may add more water, and consequently diluting the AdBlue®. Ensuring that you are not buying diluted fluid is important – a weakene...
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...
