You received grant money for DPFs, now you learn you need to clean them. Now what?
Does anyone have experiences/lessons learned that they can share?

Retrofit filters without passive regeneration systems typically plug with soot much more often than engine systems equipped with active onboard regeneration systems. Active regeneration systems have the ability to burn off accumulated soot and thereby keep the filter clear.
Filters can be re-plugged within hours of cleaning if the engine is malfunctioning, operating temperatures are out of specification or if the wrong fuels or lubricants are used. We have seen filters run over 200,000 miles after cleaning and filters that re-plugged in two hours. The ash that plugs a filter loads linearly in the filter based on engine hours and rpm. The loading rate of ash will vary due to the lubricants used, engine condition, and fuel quality. Usually it takes quite a period of time to plug a filter with ash. Soot plugging can occur very quickly and is usually due to a very unfavorable operating condition such as low filter temperature (frequently experience by school bus operators) or engine problems.
As a result, TRP Bus Parts & Service Dealers have installed over 120 FSX Diesel Particulate Filter Cleaning Machines in North America to assist customers with DPF cleaning.
