Congrats on the Alpha! You'll enjoy it, but I find it very unlikely that the current engine variants will pass the 2010 engine specifications that will be in force. 50% of all engines by 2008 must conform to the stricter ULEV-II emission standards that Tier 2 Bin 5 requires, and that includes the big rigs as well.

ArvinMeritor to supply ActiveClean to GEP

Jun 1, 2006 12:00 PM


ArvinMeritor and General Engine Products (GEP), a solely owned subsidiary of AM General, jointly announced an agreement under which ArvinMeritor will supply its ActiveClean atomizer technology, as part of the emissions control aftertreatment system for GEP's 2007 Optimizer 6500 V8 TurboDiesel engine line. The aftertreatment system will help the Optimizer engines meet United States Environmental Protection Agency (EPA) engine emissions regulations that go into effect in 2007.

?ArvinMeritor's atomizer product provides uniform disbursement of diesel fuel into the exhaust stream at the optimal particle size, so that the fuel can provide efficient regeneration of a diesel particulate filter and/or a lean NOx trap,? said Silvio Angori, general manager of ArvinMeritor's Commercial Vehicle Emissions business.

The atomizer is part of a system of aftertreatment components that process diesel engine exhaust to enable engines to meet 2007 EPA emissions regulations. GEP will also use exhaust gas recirculation (EGR), oxidation catalysts, particulate filters, and nitrogen oxide traps to meet the new emissions standards.

The way I understand it, the new system (that DaimlerChrysler will use in their commercial vehicles come 2007) is made of 3 parts.

1) A Thermal regenerator - it reheats the exhaust gases to burn more completely and reduce soot

2) The Plasma Fuel generator - this is the "ActiveClean" part. It burns diesel fuel into hydrogen gas and carbon monoxide, then injects this modified exhaust into the standard diesel exhaust stream.

3) You have soot traps and selective catalyzation to reduce the nitrogen oxides.

Supposedly, this system is small enough to put it in existing vehicles. It creates a TON of heat however, up to 600 degrees F. I can see the useablility of it in larger vehicles, and I realize that AMG's GEP states that they will use it, but I find it really hard to see how it will fit into an H1 chassis tunnel, working around the transfer case, the frame, and other stuff. If it's the same diameter as the stock exhaust (3.5" diameter at the flares), its possible. The heat issue is what's really going to be a hard thing to overcome.
