@StarBear & @wonkipop want to hear from members who own 1974 1.8s.
to assist with a topic in originality section of the website. Cars need to be reasonably original with L jet fuel injection system intact. If you have the time and can help us with some information it would be great. information. 1. Vin Date - month and year (no need to post vin numbers if you don't want to). thats the date on the driver door sticker. 2. Karmann plate #. or if you have already done the maths, the day and week of the year the car began production. 3. Image of engine bay emission sticker (lhs above the air cleaner - white with red letters). sticker should say whether it is an EC-A or an EC-B engine and whether it is california + EPA or only EPA. 4. image of engine tune up sticker. this is the small white sticker that is on LHS engine tin just below fan shroud. most of them are gone by now, but some engines still have them. 5. image of the throttle body. image of the distributor. we are looking at the vacuum hose set up between the distributor and the throttle body. ----- (IMG:style_emoticons/default/beerchug.gif) |

this is the only other thing i know about US smog tests.
you guys would know better than me? - i had to go back over old stuff in my file. i did do one smog test for the car when i lived in chicago. it had to only pass the low idle test. i assume that meant the standard at the time the car was sold new was the standard for ever after - so this was the chicago smog test that applied in 1974? i did find some stuff that said chicago was an early adopter of smog testing right behind LA. (it looked like i passed the high idle test as well even though it was not necessary? though i don't understand the CO/CO2% mix bit). a bit more snooping seemed to show that initial california smog tests back when they started doing it were also only single speed tests at low idle. all california was most interested in at the time = NOx at idle? (ie jammed in LA traffic at a standstill pumping out the main ingredient of smog?). if you look at that emissions standards material i posted above, California was prepared to wear higher CO emissions as a pay off for lower NOx. (thats what happens if you lower combustion temps to reduce NOx, CO goes up so their higher CO than 49 states makes sense). they only have to wear higher CO for one year - in 75 they get cats which turn the CO into CO2 (at that time considered a relatively harmless gas in pollution terms). thats all the material i've got on evil emissions regs Van. |
