Guided Notes
3 key concepts
- 1
Exhaust Gas Recirculation (EGR) systems reduce NOx emissions by recirculating exhaust gas, which lowers the combustion temperature.
- 2
Diesel Particulate Filters (DPFs) capture particulate matter, which is then burned off at high temperatures to maintain clean exhaust.
- 3
Selective Catalytic Reduction (SCR) systems inject a urea-based reductant to convert NOx into harmless nitrogen and water.
