DPF Filter Cleaning Saves Money!
Diesel particulate filters trap soot from the exhaust and ash from motor oil. Most soot is burned off in the course of a truck's operations. (Exhaust in highway trucks is usually hot enough to burn off most soot-this is called "passive regeneration" or "on-board regeneration".)
Active removal of soot through on-board regeneration can occur one or more times a day, depending on your type of driving and operation. Often it goes unnoticed by the truck driver, who may or may not see the indicator light in the instrument panel. But sometimes a warning gets more insistent through the light indicators. In this case, truck drivers need to stop and begin an active regeneration.
Most DPF filters collect anywhere from 7 ounces to 21 ounces of ash.
Ash from motor oil stays in the filter's substrate and must be periodically blown or washed out. If your driving and engine involve stop-and-go operations, or your heavy truck diesel engine idles a lot, the diesel engine doesn't get its exhaust hot enough. The latter must "actively" burn out soot from the substrate by injecting extra fuel just upstream of an oxygen catalyst or by plugging in an electric heater when parked.
Sometimes an engine produces extra soot, or spits out unburned fuel and burned motor oil. These, too, are captured by the DPF, and usually it cannot burn them out through normal processes. So the substrate must be removed from the DPF, then heated and baked in a special machine to burn out the crud. (About 10% of Diesel particulate filters brought in for servicing need this.)
Overall filter life decreases when impacted ash is left in the filter cells. The problem? The deeper the impacted ash becomes, the harder it is to remove in subsequent cleanings.
Ash stuck in the DPF filter causes cold cells and leads to premature soot plugging. It is simple: the cleaner the DPF filter is kept, the longer its overall life.
This is done by removing the DPF from the truck and placing it on a special machine. It sends compressed air through the substrate in a series of measured puffs.
Blowing or washing out of ash must be done every 50,000 miles or once a year. DPF filter cleaning reminders are indicated by a warning light.
