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...
The SCR/Urea Solution is aimed to apply the stricter emission regulations for Vehicles or heavy machineries with diesel engines. The particulate matter and nitric oxide are the main sources of pollution coming out from the exhaust system, and there are two main after treatment technics worldwide, the SCR and the EGR+DEF. The SCR is mainly used in Euro and Asia, but also the US since 2010. As...
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...
AdBlue® is non-flammable and non-explosive. It is classified as a transportable fluid with minimal risk. If you ever spill AdBlue® on your hands, simply wash them thoroughly with water. Gloves can be worn if you have sensitive skin to avoid any risk of irritation. However, you should wear protective clothing if you are handling large quantities of AdBlue® with the risk of a spill. Do n...
From 2013, trucks and diesel engine cars have been created to allow users to refill their own DEF tanks. As a result, a number of truck stops and gas stations have begun offering a DEF pump next to the diesel fuel pump. You may even purchase small quantities—or order large containers for commercial use—to keep at home. Although safe to handle and non-toxic, AdBlue® can eat through some metals....
The need to control toxic emissions from diesel combustion engines is ever-increasing. AdBlue® are being developed to manage the output of poisonous gas like nitrogen oxide(NOx) from engine exhaust systems. Selective Catalytic Reduction(SCR) is a method of controlling nitrogen oxide emissions. This process requires diesel exhaust fluid, namely AdBlue®, to be injected into the exhaust pipe ...
China's economy continues to develop rapidly and the demand for oil resources continues to grow in recent years. According to statistics, China's oil consumption in 2013 was about 490 million tons, resulting in more and more significant air pollution. The severe haze in winter in some cities of China has become more and mo...
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...
