Diesel Exhaust Fluid (DEF) is an important element in fashionable diesel engines geared up with Selective Catalytic Discount (SCR) techniques, reminiscent of these present in Duramax engines. The fluid is a non-toxic resolution of urea and deionized water, injected into the exhaust stream to cut back nitrogen oxide (NOx) emissions, thereby serving to automobiles meet stringent environmental rules.
Correct DEF use is essential for optimum engine efficiency and longevity. Using a high-quality fluid ensures the SCR system features effectively, stopping potential injury and minimizing the danger of decreased energy or engine shutdown. Traditionally, the event of SCR know-how and the next want for DEF has considerably contributed to cleaner air and a discount in dangerous pollution emitted by diesel automobiles.
