California emissions ?

[hat_man]

I know the title must have had some heads shaking, but yes....I do know what California emissions are in relation to non California emissions.

I've seen the terms California emissions and Evaporative emissions. Is there a difference in these two terms or are they interchangeable? If they aren't the same, then is one stricter than the other?

Thanks

All I know is California has the strictest air regulations in the country.
But when you look up America heart and lung associations list of "cities with the worst air quality" the top 5 or 6 are in California.

In California I believe they have their own evaporative emissions standards too in addition to tail pipe.

When I lived there evap was a subcategory of engine emissions. However, in the intervening years it has become a category on it's own because there are other VOC sources. They are both the same in regards to reducing smog, but methodology and attainment differ.

The reason I ask is I'm back on the fuel injector swap and am finding more possible options. Some say California emissions and some say Evaporative emissions. The California emissions ones are red and the Evaporative emissions ones are dark blue. I'm sure they are colored for specific identification. As far as I can see so far they will fit my new Ranger.

I'm just trying to research them all a little more.

Correlation =/ Causation

They have the strictest regulations because they NEED the strictest regulations. Pollution gets trapped and doesn't disperse as easily as in other areas vs California.

OP:
Evaporative emissions have to do with controlling gas fume leakage from gas tanks. As far as I know, new cars all have EVAP canisters to collect fumes and prevent venting to atmosphere, but other things such as motorcycles and small engines don't necessarily have these EVAP canisters. A California emissions model would have an EVAP canister.

It's not just California.
I believe about 15 or 16 of the top 20 most air polluted cities in the US are all environmentalist democrat ran cities.
And they think their ideas are best for protecting the environment...

The term “California” emissions is a bit misleading as 13 states officially use the emission standards set by C.A.R.B. (California Air Resources Board) and 1/3 of new cars are sold in these states. The EPA adopted CARB standards starting in 2016 so as of today there is only one emission standard.

During emission testing the vehicle is run on a dyno in a specific pattern and the gases coming out of the exhaust pipe are collected and analyzed. Evaporative Emissions is a separated test. The vehicle is placed inside a box for 48 hours and no more than 2 grams of hydrocarbons can leak out of the vehicle.

To be certified by CARB the vehicle must past both tests so I have no idea why you would find parts labeled for one or the other. Especially not fuel injectors.

These are the options I am seeing. I also see the California emissions part and the Evaporative emissions part do have the same part number so maybe the terms are interchangeable?

Sorry it's so small. Working on the tablet and I'm not sure how to resize the pic on it.

It doesn't have anything to do with their political persuasion. When you crowd enough people together, driving cars and using electricity and all the things modern humans love to do, dense, highly-populated cities like NYC, Dallas, Phoenix, LA, etc. have higher concentrations of ozone and particulates (the AHLA maintains three separate lists ranking cities by ozone, long-term particulates, and short-term particulates). Conversely, cities with low density and low population generally have better air quality, but we're talking places like Casper, WY, Bangor, ME, and Decatur, IL, where not a lot of people live because they're in the sticks. Keep the politics to the Lounge, please.

I wouldn't put much stock on the picture but since the two red parts are the same number they are likely both the CARB version. I suspect the others are the EPA version but I would call and check. It is likely just a poor description from Rock Auto. I run into that type of thing pretty often on discount part sites.
