how do you clean a dpf filter while driving
With DPF and check engine lights. After a quote of about $2500 for a new filter I decided to take matters into my own hands. I'm no mechanic but didn't need to be. After a lot of forum research I took the whole DPF filter off for a look. I removed the three sensors and found the problem. Both sensors at the exit side of the filter didn't look good.If the active regeneration process occurs during a short journey, and the engine is turned off before it can be completed, your DPF warning light will appear to tell you that the filter is partially blocked. …. Sometimes, a hot and pungent smell can also start coming from your engine as the soot is being burned away.
Using Redex DPF Cleaner (either when your light comes on or regularly as a preventative measure) will help the soot to burn away during normal driving, so that your filter clears, and the light stays off. This can save you a lot of time, money, and stress, as a new DPF will typically cost around £1,000.
Do not use high pressure you will cut into the filter and do not waste the money on reman buy new less headaches more miles before it need to be done again. More guys are buying a new filter and getting back to work trying to save a buck will cost you more i down time and labor. Also change def filter and injector same time depending on yourAdd a DPF cleaner. These products lower the combustion temperature of soot so that it burns off more easily during regeneration. A pressure gun and compressed air can be used to remove loose ash in the filter, but not the stuck soot particles. Pressure-wash the DPF filter with heated water, spraying in the opposite direction of the exhaust flow.
Also, the flanged DPF the IH uses places the filter element about 12 or more inches from the heating element, and the small hole in the flange may reduce air flow reducing effectiveness. I could see IH requiring special techniques on this style down the road. No 2011 vehicle should need cleaning yet.
The TerraClean range of tools and equipment enables TerraClean dealers to clean injectors, combustion chambers, EGR Valves, Diesel Particulate Filters (DPFs) as well as sensors to help achieve optimum engine efficiency. Do not consider hydrogen-based technology or basic carbon cleaning alternatives – insist upon TerraClean every time. Passive regeneration happens naturally while driving without the driver having to initiate the cleaning process. In order for the engine’s exhaust gases to reach high enough temperatures for the soot and ash to be burned off (greater than 350°C or 662°F), the vehicle must be driving at 70 mph or above for at least 45 minutes.
