DPF Cleaning Services: The Reasons Behind Equipment Aided Ash Removal
This is a question. Since 2007 all Dodge Cummins 6.7, Ford Powerstroke 6.4, and Chevy Duramax 6.6 trucks come from the factory equipped with a particulate filter to meet tougher emissions standards. A diesel particulate filter Truck Dpf Related Problems is a device that traps the soot and unburnt fuel from diesel combustion. In the event you have one the 07 diesel pickups that it really never puts out any black smoke in any way, you might have found. The DPF will capture better or 90% of all harmful diesel emissions. Once the DPF has become "complete" of soot, it'll have to really have a regeneration cycle so that you can combust all the soot out.
Essentially what is occurring during this technique is that the computer of the engine has decided from the info it receives in the detectors installed in the exhaust that the DPF has filled up past the okay limit of it's. The computer then opens the EGR (exhaust recirulation valve) adding hot exhaust to the intake to help get get exhaust gas temps higher and also injects a tiny chance of fuel into the cylinders when the exhaust valves are open. The raised exhaust temps and the small amount of fuel subsequently burn out the particulate (soot) that the DPF has accumulated since it's last regen. Once the computer gets readings from the sensors in the exhaust that the filter is flowing an acceptable limit again, it ends the regen cycle. The frequency of the cleaning cycle differs from vehicle to vehicle depending on use, mileage, and engine state.
Myths about the DPF system:
Not in any way. As I stated above, the fuel required for cleaning the dpf is entered through the exhaust stroke of the engine by route of the regular fuel injectors to the engine cylinders. A small chance of fuel is pushed out with all the remainder of the exhaust gas. The metal lines everyone sees on the side of the DPF filter are for a pressure sensor that is generally connected to the face of the transmission or framework. The other wires you see visiting the exhaust before and after the DPF filter aren't spark or glow plugs. They are thermocouples that temperature exhausts. The computer uses exhaust temperature and pressure at, and after the dpf to quantify how plugged the dpf is and when it's time to do a regen.

2. I can just remove the DPF filter and put a piece of pipe in there.
Sorry, no. In the event you also make no adjustments to the computer of the engine and remove the DPF filter, it's going to enter a continuous state of regen or either a limp mode. To put it simply, all the sensors as well as the dpf have to maintain perfect working order you will not be able to drive it and when running the stock vehicle's programming or else your truck will go haywire.
Common issues using the DPF system:
1. Lousy Fuel economy - This is the number one complaint we get from customers that have trucks equipped with a DPF. Most customers who traded in their pre-07 diesel pickups have now been totally unhappy using the possible lack of fuel mileage that used to appreciate. The typical fuel economy we hear folks report on the DPF equipped trucks is typically 12-14 mpg.
2. Excessive regens - Many of our customers who use their trucks for work complain about very frequent regens that kill their fuel mileage and functionality. Many customers who work outside in the winter were used to leaving their old diesels run all day while they were on the job site. The DPF equipped trucks don't manage this well. The cooler idling temperature of the exhaust gas will soot up the DPF on an accelerated speed. The normally dealership response is: "You can not let these new trucks idle." Which goes over pretty well with guys who are stuck in work site five miles back in the woods all day and also the temperature never gets above ten degrees.
3. High replacement cost - If any of you've needed to pay for a DPF replacement from warranty, you likely had a heart attack when you got the invoice. A replacement DPF (which isn't accessible aftermarket yet) runs around $2000-$2600 for the merely the filter alone. And hears the part that is frightening. DPF life is estimated between . miles 120,000 and 150,000 In the event you plan on keeping your new diesel pick up for a few hundred thousand miles better begin a DPF fund.
4. Confines functionality adjustments - Together With the new diesel pickups, the potential for horsepower progress is tremendous. We now have taken all three brands of pick-ups to close to or over 1000 ft/lbs of torque with merely consumption, exhaust and 500 rear wheel horsepower, and programming adjustments. Never has so much performance been so easy and affordable while still keeping road manners. The sole problem is anything past the particulate filter wills aggravate. Turning up the engine will produce more soot that will stop up the dpf earlier causing more regens. Many customers who run a 100 hp application report regens that are endless and very poor fuel mileage. Our Facebook Page.
