We care about you, your Ford and the environment. Read on to know what you should do to keep your Ford’s after-treatment system (Lean NOx Trap and Diesel Particulate Filter) in good condition.
About The BS6 Regulation
BS6 or Bharat Stage 6 are Indian emission regulations that help in reducing pollution. They have been applicable from 1st April 2020. Some of the major pollutants from automobile include- NOx (Oxides of Nitrogen), CO (Carbon Monoxide), HC (Hydrocarbons) and PM (Particulate Matter). Lean NOx Trap’s (LNT) primary function is to reduce emission pollutants (CO, HC and NOx) while Diesel Particulate Filter (DPF) entraps carbon soot, thereby ensuring cleaner tailpipe emissions.
How A Diesel Particulate Filter Functions
Diesel Particulate Filter is an integral part of after-treatment and performs the key task of emission compliance with respect to entrapping/regenerating carbon soot and ensuring clean environment. Carbon soot entrapment and regeneration reset Diesel Particulate Filter for the next cycle of entrapment which occurs periodically based on the drive pattern.
How A Lean NOx Trap (LNT) Functions
Lean NOx Trap (LNT) is a part of after-treatment device responsible for oxidation of Carbon Monoxide (CO), Hydrocarbon (HC) into Carbon Dioxide (CO2) and Water (H2O). It is also responsible for Nitrous Oxides (NOx) entrapment/purging with reduction reaction to Nitrogen (N2) and Oxygen (O2). Sulphur accumulation on LNT is a phenomenon due to available Sulphur in diesel fuel. Excessive Sulphur accumulation leads to drop in efficiency of the LNT to control NOx emissions.
Causes For Blocked DPF & LNT Filters
Short journeys in the city
Heavy traffic
Driving at a lower speed for long intervals
Driving in hilly regions
Note: LNT regeneration will not happen at altitude above 2500 metres.
All About DPF Regeneration
| Cluster Message + Malfunction Indicator Light |
|
 |
Customer to drive vehicle for about 60 kms, >60 kmph in 4th/5th gear continuously such that the engine speed reaches to 1500-2300 rpm (as high load/high temperature is required to clean the DPF Filter). |
 +  |
Customer to drive vehicle for about 60 kms, >60 kmph in 4th/5th gear continuously such that the engine speed reaches to 1500-2300 rpm (as high load/high temperature is required to clean the DPF Filter). |
