SCR is an advanced active emissions control technology system that decreases tailpipe nitrogen oxide (NOx) emissions to near-zero levels in newer generation diesel-powered vehicles and equipment.
The Global Selective Catalytic Reduction (SCR) Systems market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Tenneco Automotive To Launch Series Production Of Silencers With Integrated Selective Catalytic Reduction (SCR) Technology. Tenneco Automotive announced that it is one of the world's first firms to combine a catalytic converter and exhaust silencing components in a single unit for commercial cars.
The business created a silencer that meets the stringent acoustics, backpressure, and flow distribution requirements required to ensure that DaimlerChrysler's SCR system complies with both Euro 4 emissions rules and acoustics constraints.
This comprises integrating the SCR catalyst into the silencer as well as distributing exhaust gas on the catalyst to meet Euro 4 emissions requirements. The SCR system also employs the first use of isothermic canning of fully-extruded substrates.
Diesel engines can be made to comply with the stringent Euro 4 emissions standards well before the deadline for compliance by using SCR technology to reduce nitrogen oxides (NOx) emissions. In order for the system to function, precise amounts of urea solution are injected into the exhaust fumes, where they are transformed into ammonia.
The toxic nitrogen oxides are then changed by the ammonia into safe nitrogen and water vapour. DaimlerChrysler has already made plans to employ SCR technology in order to meet the upcoming Euro 5 regulations.
Tenneco Automotive is a pioneer in creating and manufacturing cutting-edge exhaust after treatment systems that assist automakers in adhering to ever-stricter pollution laws. The business was one of the first to produce diesel particulate filters in bulk for use in passenger cars.
A twin-dosing selective catalytic reduction (SCR) system is being introduced by Volkswagen AG, and it has the potential to cut nitrogen oxide emissions from diesel-powered vehicles by as much as 80%.
Using a 2.0-liter 4-cylinder "TDI Evo" diesel engine, the system will debut this summer in Europe in the Passat midsize sedan (shown). According to VW, the system satisfies the most recent Euro 6 emission regulations.
Later, more vehicles will gradually begin to receive the engine, beginning with the completely redesigned Golf little car, which will debut later this year. With Adblue urea being injected at two places upstream of the SCR catalytic converters, the system has two of them set up in sequence.
According to the automaker, the dual configuration enables the devices to function more efficiently by treating emissions at various temperatures as they travel further from the engine.
In comparison to previous generations of vehicles with a single SCR, VW claims that real-world testing of the new Passat and Golf diesels with twin-dosing showed an 80% reduction in NOx emissions.
By injecting a urea-water mixture known as AdBlue, which is standardised in Europe, into the exhaust stream, SCR lowers NOx.
The technology is used by the majority of automakers.Shortly after the company's diesel pollution cheating scandal surfaced, VW, which had been utilising less-expensive lean NOx traps, started making the move to SCR.
The Delphi Corporation developed the first automobile ammonia sensor ever. SCR (Selective Catalytic Reduction) systems, which are utilised by a growing number of diesel vehicles to reduce NOx, will be directly closed-loop controlled by the new technology.
The sensor enables better urea injection and a decrease in ammonia emissions by directly measuring the ammonia coming from the exhaust. Urea is a substance rich in ammonia and necessary for the SCR system.
As SCR levels rise to comply with new emissions requirements in both light and heavy duty diesel vehicles, control of urea injection is anticipated to become a priority that will rise quickly.
Although car exhausts are far cleaner now than they were even a few years ago, that doesn't mean that they shouldn't continue to make improvements.
Ammonia emissions are a possible concern with the increase in diesel vehicles utilising extensive SCR that they want to help their clients address before it becomes an environmental disaster.
Nitric acid and airborne chemicals such as atmospheric ammonia combine to form dust-sized airborne particles, which can resemble smog. Currently, the majority of ammonia emissions come from industry and animals, making up a fairly minor part of all ammonia emissions.
Both in light-duty and heavy-duty applications, the use of SCR is anticipated to rise sharply. The technology is already well-established in the European market for heavy duty trucks, and it will play a bigger role in the American market going forward to ensure compliance with new heavy-duty requirements.
