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...
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...
- 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 ...
Introduction As the emission standard of European is announced, Adblue solution becomes a controversial chemical production. The main purpose of Adblue is reducing Nitric Oxides in the emission of diesel engines. Therefore, a series of environmental issues will be decreased. However, a plenty of truck drivers are not willing to purchase this solution due to higher cost of delivery. The Adblue Emul...
1. Shield the vicious circle caused by the SCR system Blocking the work of the scr system will leave the nozzle in a helpless situation and can only wait in a high temperature environment. Urea pumps and pipelines that have not been operated for a long time will crystallize and block due to the evaporation of the remaining liquid moisture. 2. No regular replacement If dust is accidentally brought ...
About the Selective Catalytic Reduction system of the diesel vehicle SCR is a technology that uses a urea based diesel exhaust fluid (known as AdBlue or DEF) and a catalytic converter to significantly reduce oxides of nitrogen (NOx) emissions. All major engine manufacturers have stated that they will eventually use Selective Catalytic Reduction (SCR) to strictly enforce engine emissions regulation...
