Maximize your engine's efficiency and lifespan with our After Treatment Diagnostics (DEF & DPF) service. We assist in reducing pollution and ensuring your fleet is environment-friendly.
After Treatment Diagnostics (DEF & DPF) involves assessing and rectifying issues related to Diesel Exhaust Fluid (DEF) and Diesel Particulate Filter (DPF) systems. DEF is required for Selective Catalytic Reduction (SCR) to lower NOx concentration, while the DPF traps and stores exhaust soot to reduce emissions from diesel engines.
Routine diagnostics ensure both DEF and DPF systems' effective operation. This contributes to reduced emissions, improved engine performance, and compliance with environmental regulations. It also prevents premature system failures and costly repairs down the line.
Consider this service when there are indicators like reduced performance, increased fuel usage, or check engine lights related to the after-treatment system. Routine scheduled checks are also recommended to detect potential problems early.
