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...
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...
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...
It's difficult to determine the exact number of trucks that require AdBlue® in the world. AdBlue® is commonly used in diesel engines equipped with Selective Catalytic Reduction (SCR) systems to reduce nitrogen oxide (NOx) emissions. These systems are widely used in heavy-duty trucks and buses in Europe, but are less common in other parts of the world. It's estimated that there are over 100...
With the continuous expansion of the global Marine Gas Nitrogen Oxides (NOx) Emission Control Area Tier III, the design, installation, operation and application of Selective Catalytic Reduction (SCR) systems on ships have received increasing attention. An increasing number of ships are being equipped with SCR systems. The SCR system is mainly used to catalytically neutralize and reduce nitrogen ox...
