DPF regeneration alternatives

[teoman]

Just read this old thread (I am a relatively new member and trying to catch up on everything)

Would it not be beneficial to insulate the entire exhaust system with exhaust wrap? That would keep the temperatures higher which could mean that the dpf burns up the particulates stuck in it faster.

Just a thought...

Sounds like my 1500w heatgun is just under the required temperature.

Did an experiment mesured power consumption with a Kill A Watt gauge ,on a 1500 w heat gun/internal digital thermometer/ thermostat


maintain + - 5°f (2°c) 932°f (500°c)
max temp/ Max fan
warmup 1289w 11.08A
Maintain 932°f 1089w to 1289w cycletime ~ .5sec high ~ 1 sec. Low

Max temp/ Min fan
Warmup 1156w 10.98
Maintenance 771w to 1109w cycle time ~ .25 high ~ 1 - 2low

Fan only
57.8 watts .30A

add a few drops/min of diesel and you have a regen temperature without the engine running . Well under the max load for a standerd 110vac wall plug. Wether or not the CFM is within specifications to clear the ash without allowing it to become one with the ceramic. I dout it ... this could be run off a properly sized bank of suppercaps/supplemental Deep Cycle Battery to alow the regen to finish what it started.

If for home use,

This sounds like a perfect excuse to build an electric foundry. But with one door that has a heatproof hose compatible for the dpf.

The solution to my VW's DPF woes was to use DPF cleaner (bought cheaply in bulk from a tractor supply) and use it every tank.

One time it took 200km of highway miles to get the DPF light to go out. With DPF cleaner, problem solved, never had a light since.

The fuel saving seems to be about the same as the cost of the additive.

Renault are claiming the DPF in my new Trafic is good for life, and they claim the engine is good for 400,000km. I'm still using the additive.

good for 400.000, but lasts longer if treated well.

We have a lot of vans driven a half million kms here.
