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...
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...
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...
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 ...
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...
Exhaust gas treatment fluid, commonly known as automotive urea fluid, is a consumable that must be used in SCR technology and is mainly used for exhaust gas treatment of diesel engines. With the policy for energy conservation and emission reduction, most light trucks on the market are now equipped with urea tanks, but many people cannot tell well what is the difference between automot...
