Why Diesel Engine Particulate Filters Matter
Modern DPFs capture 85-100% of harmful particulates from diesel exhaust systems:
- Health protection: Reduce respiratory risks by filtering carcinogenic soot particles
- Regulatory compliance: Meet Euro 6/EPA Tier 4 standards
- Engine longevity: Prevent backpressure damage to critical components like turbochargers
Diesel Particulate Filters (DPFs) play a crucial role in reducing harmful emissions from diesel engines. They capture soot and other particulate matter before they can enter the atmosphere, helping to comply with stringent environmental regulations and enhance vehicle performance. DPFs are essential components in modern diesel engines, designed to meet increasingly strict emission standards such as the EPA Tier 4 regulations for nonroad diesel engines introduced in 2008-2015.
How Diesel Engine Particulate Filters Work
Our ceramic-substrate filters use advanced thermal management:
- Passive regeneration at 350°C+ during highway driving
- Active regeneration via fuel injection for urban vehicles like the Citroën Berlingo
- Ash accumulation monitoring through differential pressure sensors
DPFs utilize a porous ceramic wall-flow monolith, typically made of cordierite or silicon carbide, packaged into a steel housing. As diesel exhaust passes through the filter, soot particles are trapped within the porous walls. The filter is coated with a catalyst that promotes chemical reactions between components of the gas phase and the collected soot, facilitating its oxidation under lean conditions in diesel exhaust through NO2 and oxygen-based reaction mechanisms.
Maintenance Best Practices
Catman recommends these proven strategies:
| Interval | Action | Benefit |
|---|---|---|
| 5,000-8,000 hours | Professional ash cleaning | Prevents clogging |
| Monthly | Motorway regeneration runs | Maintains flow efficiency |
Regular maintenance is crucial for optimal DPF performance. The RAC recommends making sure the DPF can fully regenerate when it’s full of soot. This involves two types of regeneration: passive and active. Passive regeneration occurs during long motorway journeys at sustained speeds, while active regeneration involves extra fuel injection to raise exhaust temperature and burn off stored soot. It’s advised to give diesel vehicles regular 30 to 50-minute runs at sustained speed on motorways or A-roads to help clear the filter as part of routine maintenance.
