Understanding the Diesel Particulate Filters

What Is a Diesel Particulate Filter (DPF)? 

Diesel Particulate Filters (DPFs) are crucial components in modern Class 6-8 trucks, playing a pivotal role in reducing emissions and maintaining environmental standards. Essentially, a DPF is a device installed in the exhaust system of a diesel engine to capture diesel particulate matter or soot from the exhaust gas. This filtration process is vital for reducing the amount of black smoke and fine particles that diesel engines historically emitted

Understanding the Diesel Particulate Filters

How DPF Works

The way DPFs function is relatively straightforward yet ingenious. The exhaust gas flows through the filter, where the soot particles are trapped. Over time, the filter accumulates a significant amount of particulates, necessitating a cleaning process known as 'regeneration.' This process involves burning off the accumulated soot at high temperatures, converting it primarily into carbon dioxide and water vapor. However, DPFs can become clogged over time due to incomplete combustion, especially in situations where trucks do not reach the high temperatures required for passive regeneration (such as frequent short trips or urban driving conditions). When this happens, active regeneration is required, where extra fuel is injected to increase the exhaust temperature and clean the filter. While this regeneration process is effective, it's not entirely efficient or sustainable in the long term, as the DPF eventually requires thorough cleaning or replacement. Historically, cleaning methods like using an Air Knife – which involves blowing compressed air through the filter to remove particulates – have been common. However, this method has limitations, particularly in thoroughly cleaning the filter and ensuring its long-term functionality. Partner with Ceramex to ensure an extended life of your DPF.

Keep It Clean: DPF Maintenance Tips 

Regular checks

Have you DPF Serviced with Ceramex’s patented technology every 300,000 miles or per manufacturers guidelines for service intervals. If the vehicle has either high idle times, or is predominantly stop and go; Ceramex recommends the filter is serviced at a lower interval than recommended by the manufacturer.

Don't ignore warning lights

Address DPF Warning Lights immediately with professional service to prevent costly emission system repairs along with unscheduled down time.

Use a low ash Oil

Low ash oil produces few metallic ash residues during combustion, which can accumulate and clog the DPF. This reduces ash accumulation delaying the need for a DPF cleaning or replacement.
