The Diesel DPF Dilemma

in Diesel

If there was a way to make your street-legal diesel particulate filter (DPF) equipped diesel truck perform at the same level as an off-road racing DPF-deleted rig, would you want to know how?  DPF Deletion is great for off-road racing, but what about the rest of us who just want better fuel economy, improved towing and diesel performance?

Most late-model diesel truck owners are now familiar with the term DPF.  If you used to get 15-20 miles per gallon on your pre-DPF diesel truck, you were probably shocked when you first figured out that your brand new $50,000 diesel got 8-13 MPG.  And how about the first time you were towing a heavy load up a long grade when your diesel suddenly went into DPF regeneration and your speed plummeted to the point of being dangerously slow? If you're like thousands of other diesel owners, you've been looking for a way to safely and legally improve your diesel fuel economy as well as increase horsepower on your DPF-equipped 2007.5 to 2010 Dodge Ram 6.7L Cummins, 2007.5 to 2010 GM 6.6L Duramax, or 2008 to 2010 Ford 6.4L Powerstroke.  Now there is a new option that will give you exactly what you want!

Many of the major manufacturers of diesel performance aftermarket products have tried to figure out an effective way to reverse the performance and fuel economy-reducing effects of the emissions control DPF device.  Matt Snow and the diesel performance geniuses at Snow Performance have found a simple yet brilliant solution.  Installing one of their Diesel Stage 3 MPG-Max Boost Cooler water-methanol injection kits on a DPF-equipped truck gives a boost in fuel economy of 1-3 MPG, with most diesel owners getting over 2 MPG.  And here's the best part - the more often your truck was going into DPF regeneration before installing the Boost Cooler kit, the bigger your fuel economy gains will be.  Let's look at the reasons why.

A diesel particulate filter is designed to remove soot and other particulates from the exhaust gas stream.  The filtered soot and particulates build up until the filter needs to be cleaned, a process call "regeneration".  In the Dodge, Ford, and GM diesels that are so popular in North America today, filter regeneration, or cleaning, is achieved through using a fuel burner that heats the particulate filter to the combustion point of the soot and particulates.  Every time your filter has to be cleaned, more diesel fuel has to be burned to heat the filter.  And, as you might imagine, this doesn't help with diesel fuel economy.  

The product development team at Snow Performance already knew that pre-DPF diesels utilizing their Boost Cooler kits experienced decreased emissions of particulate matter and NOx due to increased combustion efficiency.  Injected methanol acts as a combustion catalyst, meaning your diesel fuel gets burned more efficiently and more completely.  Instead of sending unburned fuel and particulates out the tailpipe as smoke and pollution, using the Snow Performance water-methanol injection kits on pre-DPF diesels caused their emissions to drop dramatically.  What they didn't know for sure, but suspected, was that their kits would have an even more beneficial effect on the new diesel trucks coming out with DPF's installed.

The Snow Performance crew was right.  Running one of their Boost Cooler kits on a DPF-equipped diesel truck still led to lower exhaust gas temperatures and increased horsepower.  Most importantly, the water-methanol injection kits improved combustion efficiency so dramatically that the particulate filters on their test trucks just never got dirty enough to need to be cleaned.  The exhaust stream was "scrubbed" so effectively by the water-methanol injection that the filters didn't need to go into regeneration mode.  This of course led to even greater and consistent gains in fuel economy.  

For diesel performance enthusiasts, combining a Stage 3 MPG-Max Boost Cooler water-methanol injection kit with a diesel performance chip, programmer, or tuner allows you to use today's popular electronic power-adders without the worry of clogging and ruining your expensive particulate filter.  Now you can have your diesel performance cake and eat it too!  For increased fuel mileage, more horsepower and torque, a better towing experience, and reduced emissions without resorting to DPF deletion,  invest in a Snow Performance Stage 3 MPG-Max Boost Cooler water-methanol injection kit for your DPF-equipped Cummins, Duramax or Powerstroke diesel today!
