DPF Cleaning

The Diesel Particulate Filter is a device installed in the exhaust stream in all new diesel engines made after January 1, 2007. The DPF is comprised of two chambers. The first chamber works to oxidize a portion of the NO gas in the exhaust to NO2. The second chamber then destroys the soot that is trapped inside. The result of this process is a small amount of ash which remains in the filter. This ash builds up and reduces the effectiveness of the DPF which must be cleaned. DPFs on all 2007 and later engines must be cleaned at proper intervals of approx. 200,000 miles* for highway applications. Severe service vehicles with high idle times and little on highway driving, may need its DPF cleaned in as little as 75,000 miles**.

KNOW THE FACTS ABOUT DPF CLEANING!

*Based on engine model/make and operating conditions

What is DPF?

Know the Facts:

The Diesel Particulate Filter (DPF) on all 2007 and later engines must be cleaned at proper intervals of 250,000* miles (400,000 km or 6,000 hours) or less depending on duty cycle and manufacturers’ recommendations.

Maintenance

Know the Facts:

Many 2007 and later engines also have an After treatment Fuel Injector (AFI), or doser, that is part of the exhaust system. Manufacturers recommend cleaning this component at approximately 100,000miles (161,000 km or 3,000 hours) to prevent premature ash build-up in the DPF.

 

If left unchecked

Know the Facts:

Left unchecked, soot and ash collected in a DPF can damage or destroy a filter  resulting in a DPF replacement cost of $3,000 or more and unwanted, unscheduled downtime.
