How it works?!
The DPF looks similar to a traditional exhaust silencer, but is mounted close to the engine. Inside is a complex ceramic structure designed to filter the exhaust gases while minimising flow reduction.
By forcing the exhaust gases through the walls between the channels of the DPF, the particulate matter is deposited on the walls, so reducing the amount of air pollution. When the DPF reaches a certain level of throughput resistance it performs a regeneration cycle to burn off the particulate matter inside the filter.
Common causes for DPF failure
There are a multiple reasons a DPF can fail, the most common are:
- DPF unable to regenerate due to driving conditions
- Failed sensors preventing DPF regeneration
- Engine issues
- Poor performance tuning.
- High mileage.
- Driving in low gears on a highway disallowing the regeneration to happen.
Will it prevent me of getting through technical inspection?
No. Job is done by technicians with a lot of knowledge and experience. After our job is done noone will be able to tell if there was something done.
What are the benefits?
- you wont need to buy new DPF when it will be full and out of ability to regenerate again.
- no loss of power while DPF in regeneration
- improved gas mileage due to the removal of an air restriction allowing the engine to breather better
- improved performance
- ability to increase performance even more than before with chiptuning
