what excatly is california emissions?

 

It is the methane gas spewed forth from the radical liberals we seem to import to this otherwise great state. Unfortunately, these mouth breathing morons spew out nothing but hot air which is contributing to the "global warming" you are hearing about.
There is legislation in state congress now that would allow concerned citizens the privledge of an "Open Season" to help reduce this form of polution. Not only do they polute the air, they also cause a severe stress on our state in the form of noise polution.
For more information do a google search on "Sierra Club", "Cal State Berkeley", or "California Air Resorces Board".
The latter is more pertinent to you question. The first two will probably just **** you off.
To get a real good idea of what these liberals look like and think like search for "Al (I invented the internet) Gore".
HTH,

when i first got my car it had a v8 breather on it with a rubber tube going from it to the oil cap. i still have the same oil cap, it has a tube sticking out the side of it, and i got a 6 cyl breather but there is nothing to connect the two breathers.

cali emmissions also is referred to as the smog reducing equipment on your car.(air pump and nox device) in the old days it made your car spew a lower percentage of smog producing elements.

what they missed was, you burned more fuel negating the savings.

 

I didnt get a V8 to worry about gas prices or Emissions

 

theres are also pipes the run out from the top of your cylinder heads. Were they go and what they did i have no clue all i know is that there extremely anoying.

 

if your car is over 30+ years old, it does not need to pass smog in california.. there for, my 68' doesnt need to pass smog, cause it 38 years old..

 

hmmmmm... reading other peoples replies, i dont think my above post is valid for this question... but none the less its true....

 

California emissions are intended to reduce the amount of unburned or partially combusted fuel in the exhaust. This can be done by either carefully tuning the engine and designing the valves and combustion chamber so that full combustion occurs on the power stroke (good!) or by klugeing up the intake and exhaust systems with a bunch of add-ons to preheat the intake and re-burn the exhaust during or after the exhaust stroke (pretty crappy!). Guess what most builders do?

On the '68 (the only one I know), there is either an Imco or Thermactor emissions control system. (AT = Imco, MT = Thermactor. If there's a belt-driven air pump, it's a Thermactor.) Both reduce emissions by re-burning the exhaust. Imco does it by retarding the timing and adjusting the carb (presumably so the combustion is still going on when the exhaust port opens). Thermactor does it by injecting hot, compressed air into the exhaust port on the exhaust stroke. Either one seems like it's wasting power and fuel as previously mentioned. Nowadays the same function is done using a catalytic converter, which uses rare metals like platinum as a catalyst to get a little more of the unburned hydrocarbons, O2, and CO (toxic) to react into H2O and CO2 (not as bad). This reaction makes the catalytic converter hot, which is why my '84 Sentra had a big warning on the visor that you should not park it in dry grass.

Another emissions control on the '68 was a temperature operated flap in the air cleaner intake that would kindly draw warm air from a duct passing over the exhaust manifold until the engine was suitably warm. Sadly, mine is stuck and no longer performs this valuable function.

Sorry if this is overly technical, I studied mechanical engineering ... at the University of California at Berkeley
