ACME Partial Flow Diesel Particulate Filters (p-DPF,DPF)

The ACME® p-DPF is a non-blocking diesel particulate filter that provides effective removal of diesel particulate matter and lower backpressure than conventional wall-flow particulate filters. The ACME® p-DPF can be used in most above-ground diesel engine applications. It is ideal for retrofit on most diesel engines where wall-flow particulate filters are unsuitable, including light duty cycle, older and two-stroke engines. ACME® non-blocking, diesel particulate filters are used to improve air quality around diesel engines. The ACME® p-DPF requires diesel fuel with sulfur content less than 500 ppm for proper operation and works best with sulfur content less than 15 ppm (ULSD fuel).

Advantages of ACME® p-DPF
􀂜 Reduces up to 50 per cent Diesel Particulate Matter (DPM).
􀂜 Looks, installs and operates like a conventional diesel oxidation catalyst.
􀂜 Does not clog or accumulate soot particles.
􀂜 Requires no maintenance.
􀂜 Achieves a backpressure meeting many off-highway engine manufacturer's exhaust system limits.
􀂜 Attains a high conversion efficiency for carbon monoxide, hydrocarbons, odor and particulate matter.
􀂜 Effectively removes diesel nano-particles (highest human health risks).
􀂜 Improves sound attenuation (equivalent or superior to the original muffler).

How it works
The ACME® p-DPF is a network of flow-through channels consisting of corrugated metal foils and metal fiber fleece. The channels use a continuous but variable cross section to transfer exhaust gas through the stainless steel filter medium. Nano particles are collected within the filter on the surface of the fibres, which are effectively oxidized by means of a catalytic coating.
The coating provides high overall particulate reduction across a wide range of exhaust flows and temperatures, with backpressure characteristics similar to a conventional diesel oxidation catalyst. The design also effectively destroys carbon monoxide (CO), diesel hydrocarbons (HC) and diesel odor.
This product although being very robust and easily maintained, does not have the trapping efficiency of the full flow filter, but will not block and damage due to extreme exothermic reactions typically caused by low temperature applications.

Typical Emission Reductions from the p-DPF System
The ACME® p-DPF system is designed to give the following typical reductions in legislated emissions from a Diesel powered engine.
- Particulate PM 50% +
- Carbon Monoxide CO 90% +
- Hydrocarbons HC 90% +

@123abcpa Can confirm this. Had a temp gauge in the exhaust. In city traffic zou hardly get over 200°. And on top of it most recent engines got EGR with retarded injection timing to actually reduce the combustion temperature to reduce NOx.

There are electrically heated filters but whichever way, there's energy input to trigger the regeneration...or you use AdBlue filters. Not the best alternative though...

@urbex2007, I know what im talking about, I had a 2007 dodge cummins 6.7. burned through 4 turbos in 36,000 miles. dealer said I had to drive it on the freeway for 1/2 hour for ever 3 hours of city driving to allow the fuel to be injected into the exhaust to heat up the EGT to reach about 1100 so the soot would be turned to ash. I do almost all city driving becaus i do landscaping. I had to drive for 30min every day on hiway so that dammit to hell filter would clean. Only avged 11 MPG. Ass hole!

@123abcpa go and learn about the subject first...idiot.

[123abcpa]

I all for reducing emissions but i know for a fact that the DPF model diesels in the ford and dodge get about 10 MPG where the previos models would avg around 16-18 MPG. The DPF also makes unsafe high exhaust temps that greatly reduce the life of the engine. The benefits of the DPF are not worth what is sacrificed, it also helps suppert the middle east oil co.'s by burning way more than necessary.

Also would like to inform you that the removal of your DPF will render it illegal to register and operate on road. As well as Cummins and Duramax. And when diesels release "Soot" it is usually molecules of unburned fuel, not ash. When It burns extremely lean it will create a white ash, uncommon.

Thanks but I know the 2007+ Ford F series Diesel has a DPF but it uses Passive Regeneration which raises EGT's to burn the soot out of the filter. Im looking to use a High Flow DPF to filter my exhaust on my 1986 Mercedes TurboDiesel Car. I wish to promote the use of diesel vehicles so I believe this is the first step besides reducing obnoxious engine rattle. People feel that diesels are unclean and waste fuel when they are far superior to Gasoline Fueled counterparts.

Where can I buy one? are they expensive? Is it too large to fit conveniently on a 4 door passenger car?
