As an exhaust component continually clogging from the perpetual operation of a diesel truck, this filter is built into a system where it essentially cleans itself of the buildup. See id this helps. Contact information. With an additives investment of $200 in two city test trucks, regen cycles were reduced from 36 annually, to 6. “The DPF Regen contains the heat of the exhaust, adding up to temperatures exceeding 1000 degrees Fahrenheit, so that the filter is depleted of its buildup and returns to proper functioning capabilities.”. Multiple regen cycles can happen per day if a truck is in heavy operations. I didnt know which values to trust so i swung it. And with the fragile condition of the DPF itself, the less regens required, the better.”.

It didn’t fix the problem at all. New info. And with multiple regens come mounting costs and interruptions in daily use. Hmm, it is at 100% (open) and commanded as such. This reduces the soot burn temperature to 350-400C…a temperature readily reached by engines under even light loads. A computer sensor monitors the DPF and a dashboard indicator light notifies the driver that the regen is taking place, or the DPF is now cleaning. Anyone out there have any ideas? My Googling suggest that these are more commonly seen in trucks and 4×4 vehicles that may not be able to reach the conditions required for a “rolling” DPF regen due to either environmental (being drive off … First time the manual burn has come on , tried manual burn for 1 hour, did not work.

Then went back into regen as compressor went on again. The tighter seals provide improved combustion efficiency, thereby translating to not only better fuel economy, power and a better running engine, but also the efficiency required in the combustion cycle to prevent blow-by and added particulates flowing through the exhaust system. Mine will never warm up enough to start regen. In doing so the filter can more efficiently capture exhaust artifacts, and more easily pass through the airflow from intake to output, causing less stress on the engine itself. I perform a forced selective regen. Regen problems can be easily fixed… By far the best approach is to reduce the temperature at which the soot particles burn, by adding FTC Decarbonizer to the fuel at each fill. But I am stumped, my local Isuzu "lead tech" is stumped. EGT gets to about 800*, it goes BACK to 200-regen start and sits there half an hour, then kicks out and sets a P244C - too long in regen.

I take out the aftertreatment injector to make sure it atomizes, and look in its hole. I mean like 20-warmup, 200-regen started, 220-temp rise, 370-regen active those modes. The scan tool will display a higher percentage when the engine is running at high engine speed under a heavy load. An active regen cycle is a normal process that takes place as the truck is going down the road. Most diesel engines operate more efficiently with a fuel that has a cetane rating of 48 to 50. If the driver slows or stops the truck, the regen will stop. Like its waiting for something. Be sure to double check the codes. Should be around 20% at idle. THE REGEN TEMPERATURE IS ROUGHLY EQUAL TO EXHAUST SYSTEM TEMPERATURES ON A LONG HARD PULL. 1) DPF Regeneration. Stiction is the sticky friction caused by byproducts of burnt oil. The Powertrain Control Module monitors the conditions necessary for diesel particulate filter regeneration. “The entire system relies on the engine running well and doing everything possible to avoid repair or replacement of the DPF,” says Kyle.

DPF Regen Case Studies: I subbed for 3 days on Isuzu site and its the same info as on my scan tool, so that was a waste. With the proper lubricity returned to the fuel system however, mechanical parts are then more fluid in their operations with less friction. To those having trouble, what Ive read it seems that the Isuzus are set up to do a regen when the DPF reaches 70% blocked, whereas the Hinos are set up to regen at only 30%, so that if you delay a regen in an Isuzu, the DPF becomes critically blocked and the truck goes into limp home mode.

But when it DOES go regen active, that value isn't any different. “We force the truck’s computer to initiate the process prior to the parameter requests that happen with the active regen,” says Nace. With less friction the amount of wear and tear is reduced, better maintaining the tolerances of machined parts for a cleaner burn and more complete combustion cycle. I would download it, just in case Scott has to pull it. It sits at 200 - regen start for an hour. Log in to Reply.

In doing so the many sensors in the system will calculate the particulates prior to the DPF and post, recognizing a lack in operation of the DPF. When they came to us for an oil change, we added our Hot Shot’s Secret additives and within about a week, they saw reductions in their regen cycles and within a month, they had no more issue at all. The cetane booster in Hot Shot’s Secret Diesel Extreme for example, promotes more complete combustion, fewer emissions and therefore fewer DPF regens. Abstract: The regeneration of diesel filters is characterized by a dynamic equilibrium between the soot being captured and the soot being oxidized in the filter.Soot oxidation rates depend on the filter temperature, soot load in the filter, and a number of other factors. Nace says “the dirtier and more rich exhaust you produce, the faster it’s going to clog your DPF, therefore requiring another regen cycle.“.
