Why DEF
Why DEF is Essential?
Diesel Exhaust Fluid (DEF) is critical for Selective Catalytic Reduction (SCR) systems to break down toxic emissions into harmless gas.
STEP 01
Injected into Exhaust System
Automated doser injects pure DEF into the hot exhaust stream.
STEP 02
Reacts in SCR Catalyst
DEF vaporizes into ammonia & breaks down toxic NOx gases.
STEP 03
Converts to Nitrogen & Water
Harmful emissions are converted into harmless air elements.
STEP 04
Cleaner Air & Better Mileage
Protects environment & optimizes fuel efficiency.
