Scr

What are the benefits of using SCR technology? The high efficiency of SCR systems in reducing NOx emissions allows manufacturers to balance engine performance and maximize fuel economy, while still achieving near zero emissions. Some SCR-equipped heavy-duty commercial truck operators report fuel economy gains of more than 4%.
What are some of the ways to open an SCR file? Triggering the SCR to switch ON occurs in varying methods. They include voltage triggering, thermal triggering, light triggering, and DV/DT triggering. The first one, voltage triggering, involves applying a voltage higher than the maximum point, causing the terminal gate to open.
How does an SCR work? SCR is an active emissions control system. Hot exhaust gases flow out of the engine and into the SCR system where aqueous urea (known as Diesel Exhaust Fluid, or DEF) is sprayed onto a special catalyst.
What are the advantages of using SCR for construction projects? (An SCR can provide over-voltage protection on a circuit.) Due to its quick switching ability, an SCR keeps other electronic components safe from over-voltage. These must connect in parallel with the electrical load. When excess voltage occurs, the SCR’s gate activates.
