Diesel Exhaust Fluid (DEF) is a crucial element in trendy diesel engines geared up with Selective Catalytic Discount (SCR) techniques, corresponding to 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 autos meet stringent environmental laws.
Correct DEF use is crucial for optimum engine efficiency and longevity. Using a high-quality fluid ensures the SCR system capabilities effectively, stopping potential injury and minimizing the chance of diminished 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 autos.
