One aspect of a vehicle with SCR system is the need for replenishing Diesel Exhaust Fluid (DEF) on a periodic basis. DEF is carried in an onboard tank which must be periodically replenished by the operator based on vehicle operation. For light-duty vehicles, DEF refill intervals typically occur around the time of a recommended oil change, while DEF replenishment for heavy-duty vehicles and off-roa...
AdBlue® for vehicles is developed as the regulations for heavy-duty diesel vehicles are becoming more stringent. Particulate matter (PM) and nitrogen oxides (NOX) in diesel exhaust are the two main sources of vehicle exhaust pollution. For nitrogen oxides, the main exhaust aftertreatment technologies used in Europe and America are SCR and EGR+DPF, of which Europe and Japan is dominated by SCR,...
It depends on many factors, includes the diesel engine size, driver, DEF system condition, presence of NOx in the exhaust stream. Typically, manufacturers refer to DEF consumption as a percentage or fuel consumption. This can vary from as low as 2% to as high as 10%. So if your engine consumes 100 gallons of fuel, for a 10% DEF consumption, it would have used 10 gallons of diesel exhaust fluid def...
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...
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...
- 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...
