Air injection system

[vanhick]

What's an air injection system? My b6t swap festiva just failed the emissions test because it didn't have an air injection system. They were super secretive and wouldnt tell me what it was. According to them they were going by the factory specs and it didnt have that system. It was an 89 carbd before the swap.

well there should be no worries because after 25 years emissions doesnt matter anymore. so this year is your last year :-).

or at least i think it still works that way right?

from what i recall air injection is where a smog pump pushes fresh o2 rich air into the cat.
that way the catalytic converter has a full supply of o2 to help keep its chemical reactions high.
and reduce emissions.

since that time fuel injection has come a long way.
and now the computer cycles between rich and lean from feedback from the 02 sensors that way on the lean side
of the burn there is extra o2 left over to "refill" the cat with 02 for its reactions that also occur during the rich phase.

and this whole process eliminated the need for that pump.
kind of simplified the process..... kind of.

but if it is now fuel injection.
tell them they are stupid and there is no need for air injection anymore lol.
even though they are only concerned with factory missing hardware.

Oh no. Here in Colorado with all these liberals who are saving the planet, every car after 1975 has to have better emissions than a prius.

I think advancedynamix has strict emissions where he lives. Might PM him and see what he did to get his B6T swap to pass.

If they really won't budge on the smog pump, you could grab one off eBay and make it look installed for the check. They are cheap.

They told me I had to get it approved by some company 45 mins away. They only go by appointments on Mondays. LOL! I work, so that won't work. Do you think they just do the inspection based on what the emissions sticker on the inside of the hood says? If so, I'll just rip off that sticker and they'll be blind as to what theyre looking for. Or do they have some little database? I was thinking of trying to jimmy rig some little air injection system.

The guy I mentioned said where he lives in Arizona they have diagrams of what it's supposed to look like under the hood, but he still manages to drive his, so he did it somehow. Not sure if that's how your state does it or not.

[vanhick]

I might have to PM him, but first I'm just going to scrape the sticker and try again haha.

there is an exemption in your state for vehicles registered as street rods.
im sure you could be considered one of those sine you got the b6t.
convince them about the power to weight ratio lol.

Are they going by B6T emissions or what? None of the FWD mazdas I'm aware of used air injection / smog pumps, certainly not any B6T cars. They were common on late 80's V8 cars

Are they pulling your leg or something?

Air injection is where air is pumped into the exhaust manifold by a pulley driven air pump. I think the emissions garage has mistaken the reed valve assembly for an air injection system. Politely tell them that there never was a factory air injection pump on any Ford Festiva. Have them contact Ford Motor Company if they are unsure. If they refuse to contact Ford. Do not waste your breath or time. All Ford Festiva service parts have been discontinued since 2004. Take your business elsewhere.

It's crazy they base your emitions off what it should have. Instead of if the car actually passes the emitions tests

I think they are referring to what Ford calls the "pulse air system" on carburetted models. You can look it up in the Internet.
It's a light metal box which bolts to the driver's side of the air filtre cannister which sits on top of the carburettor (the big round black thing) with two big rubber hoses coming off it. If you don't have a carburettor there is no place to attach one.

In some jurisdictions an engine swap changes the vehicle date for emmissions purposes to the date of the swap. Good luck with the bureaucracy.

Due to EPA regulations, it is against federal law to tamper with or remove any anti-pollution device on a vehicle period. This includes catalytic converters, air injection (air pump or pulse air) systems, PCV valves, evaporative emissions systems, EGR systems, and even OBDII connectors. Simply put, if it came with it from the factory it has to be installed (and working) now.

Here in Missouri inspecting these emissions systems is part of the state-wide SAFETY inspection process - which means that even if the vehicle is exempt from Emissions testing (out of the ST Louis metro area, '95 or older, or over 8500GVW) it will still fail the safety inspection if the emissions systems have been tampered with or removed. Unless the vehicle is registered as a "Historic Vehicle" (which has to be older than 25 years old and has driving limitations) it is required to pass a Safety Inspection every other year. Even missing a gas cap or even the nozzle restrictor (to prevent you from putting diesel or leaded fuel into an unleaded car) will cause you to fail the safety inspection.

I'd imagine that many, if not most, other states have similar programs in place.

You seem like a fun guy.

Move to Florida and by pass every inspection.
