What you have shown is a rudimentary secondary air system to clean up exhaust emissions on the overrun.
A bit simple for today's application the "pots" you see below the rubber tee pieces are one way check valves to prevent exhaust gases blowing back into the inlet plenum.
Actually we have a design to encompass that application for a Pinzgauer using an electric hairdryer style smog air pump, throttle positioning switch, cold start/warm up valve, etc.
We employed something similar for a Volvo c304 that needed to have much lower tail pipe emission figures.
Currently here in the USA the emission requirements in general for Pinzguaer are very relaxed unless you take certain parts of Arizona and California into account. Here in Colorado you can actually purchase a collctors license plate and practically avoid emissions requirements altogether. Some States have no requirements at all.
The Federal requirement is 6%CO and 1200ppm of HC's by the way. There is no requirement on oxygen content or Nox as in some Euro zones or countries like Belarus. (Their limit is 1.2 CO.)
Should the authorities here actually tighten up on the limits as rumblings in Washington might suggest and encompass older vehicles like the Steyr, we would dust this and some other innovations off the shelf to hopefully make the current engine comply (hopefully!!!)

Ladies and Gents, shut down your idling engines.

I saw there was some pending State legislation when I last looked at the emissions business in Maricopa Cty last year.
So it finally arrived eh! I bet many are happy with the introduction of exemptions for vehicles like the Pinz.
One of the reasons why we have some secondary air systems and manifold pre-heat mods available is to clean up tail pipe emissions should the regulations get to a stage where licensing becomes almost impossible.
The introduction of air into the exhaust manifold of course merely fudges what is actually being produced in the combustion chamber, in short pollutants. You know strangely when we did an FI conversion to a Volvo B30 engine, (that being exactly like the 1978 164 Volvo sedan) we discovered the actual emissions of the FI B30 engine were only slightly better than its predecessor with carburetors. So in short the secondary air is just diluting the density of CO. Even today 2001 to 2004 Landovers have a secondary air injection system that is doing just the same on cold start up and operate until the engine starts to come under closed loop control. With the introduction of newer engines like LR3 this has started to disapear.
Of course with the Pinz engine the Fed limit of 6% and 1200 Hc's ppm the compliance is not really a problem but once you start to screw down the CO figures the HC's go up, that's because there's a direct correlation with these gases. HC's by the way are tiny droplets of unburnt fuel condensing on the relatively cool cylinder walls and trapped spent gases altering combustion. Over advanced timing will do the same thing, its all to do with the speed of flame travel and the degree of complete combustion of fuel in the the cylinder.
I see on the horizon some talk by Sen Libermann and J McCain on the need to curb emissions by 2008 I am interested to see if draconian measures find their way down to the collectors.
You might smell exhaust problems from your perspective, I smell money. in the short and sweet.
Cheers Dennis

Sorry Scott, I missed this. Here is the info from the ADEQ (Az Dept of Environmental Quality) web site ( http://www.azdeq.gov/function/news/2007/april.html#0402 ).Scott wrote:How exactly do we go about getting the exemption done? Simply change the insurance to collector car status and take that to MVD? Any plate change necessary?

Emission Test Exemptions Expanded to Collectible Vehicles and Motorcycles
PHOENIX (April 2, 2007) -- The Arizona Department of Environmental Quality and the Arizona Department of Transportation, Motor Vehicle Division (ADOT/MVD) today announced that collectible vehicles registered in Phoenix and Tucson testing areas will be exempt from emission tests. Motorcycles registered in the Tucson testing area will also be exempt.
The exemption begins with April 2007 vehicle registration renewals under a plan recently approved the U.S. Environmental Protection Agency (EPA). EPA studies show that exempting such vehicles from the emission testing program would not interfere with meeting and maintaining health-based standards for ozone and carbon monoxide, and would present no significant degradation of air quality.
"We are pleased that EPA has approved our request to exempt collectible vehicle owners and motorcycle riders from the emissions inspection requirement," said ADEQ Director Steve Owens. "These vehicles are not harming our air quality, so their exemption is well-deserved."
"MVD welcomes this opportunity to work with the EPA, ADEQ and the insurance industry so that collectible vehicle registrations can renew quickly and easily online at www.ServiceArizona.com ," said MVD Director Stacey K. Stanton.
The new regulation requires that owners of collectible vehicles carry special collectible vehicle insurance. Arizona insurance companies must report the special coverage to MVD electronically before the registration renewal - with emissions exemption - can occur.
How it worked for me (Sam):
I took my policy indicating that it is collector car insurance into MVD. If your policy does not indicate this you will need to ask MVD what they will accept. They made a copy of my policy and registered my Pinz w/o the requirement of emissions testing. They also entered my data into their system so that subsequent registrations (w/o emissions testing) can be done on-line with ServiceArizona.com. Of course I will need to maintain my collector car insurance in order to continue to be eligible for emissions exemption. Now, if you convert to collector car insurance be advised that this will place limits on your Pinz enjoyment. Each insurance company will have annual mileage thresholds of say, 1000, 2500, 4000 miles / year. This may not be acceptable if you drive your Pinz regularly.
Good luck.

I was in the MVD in late March and they had no idea this was coming. Glad to see that the system now recognizes it. Not much good for the way I drive my Pinzgauers and the M37's are already exempt by year. Hopefully some will be able to take advantage of this along with the insurance savings of collector car insurance. The one big problem is that now the Pinz owners who don't maintain their trucks very well can let them go even farther without the necessary care.
