Pollution gear for 9/74

Post by 2car »

I'm wondering what pollution gear I am requried to have on my 9/74 petrol passenger car. I have positive crank case ventilation and automatic choke. Do I need EGR and charcoal cannister? Are there any good references on the topic? Where can I get a copy of the relevant ADRs?

Thanks

Ben

P.S. I'm going to say 'Just put it on LPG' to save someone else the trouble :D

I had a March 1974 petrol with PCV and automatic choke.

My mother's 1975 model had charcoal cannister, but I don't think it had EGR.

I think ADR27A was the big one - what's on your compliance plate?

Good info. I'll check the plate. Did your 74 have a hot air stove?

I'm not sure what that is. If you mean a warm air intake coming from the exhaust manifold, I really don't recall. It had a Weber and extractors almost as soon as I bought it, so I don't remember the original configuration.

I don't think the '75 had that arrangement either, but I could be wrong.

If a "hot air stove" was something completely different, you'll have to explain it to me. :oops:

I thought anything pre-86 wasn't required to have emissions gear fitted, that's why you can get away without running a cat on them - and probably because they didn't have one when it came from the factory.

1986 was the introduction of unleaded petrol. Well before that we had emissions regulations which brought us the joys of
    Positive Crankcase Ventilation - feed oily crankcase fumes back into the air intake.
    Automatic chokes - can't trust people to use a manual choke properly.
    Carbon Cannisters - capture fumes from the fuel tank and feed them into the intake.
    EGR valves - recycle some exhaust gas to reduce the amount of oxygen in the cylinder, to reduce NOX emissions.
    Air pumps - inject air into the exhaust for some strange reason :?
    Skinny little exhausts - create back pressure and force the engine to warm up quickly.

There's probably others I've missed, but unleaded petrol wasn't the start of it...

Cheers,

Scott

warm air intake coming from the exhaust manifold = hot air stove.
