Parts of the vehicle produce emissions, and parts of it don't!
As I understand it from http%3a//www.arb.ca.gov/msprog/zevprog/factsheets/2008zevfacts.pdf , a ZEV cannot use gasoline. A PZEV uses gas, but is subject to much stricter regulations.
I think they're still working on perfecting the zero emission cabbie.
It's within machine epsilon of 0.0?
no emissions when the car is off.
Partial zero is as close as you can get to zero when computing with fuzzy logic.
I think I threw up in my mouth a little when I read that.
I am going to ignore the legitimate responses above and say that the car is zero emissions, but the driver farts a lot. Somebody had to go there.
That makes more sense. I figured it was a joke of some sort.
Don't even get me started on friends of mine who appear to think that electric cars are "Zero emissions vehicles". Apparently we developed factories, cargo ships and power plants that run on fairy dust while I was sleeping.
(Yeah, I just hate the term "Zero Emissions Vehicle". Because tricking people into bullshit semantics like "It's only the tailpipe emissions that count" leads to people making bullshit greenwashing consumer decisions that are arguably worse for the environment than back when they didn't care. Plus they act all smug, too!)
Don't even get me started
Doesn't seem like anyone did, given the lack of relation this has to the original post...
I like to rant.
Fairy Dust is a fossil fuel anyway, laid down in thin, sparkly strata from the crushed horns of dead unicorns during the Gummiberry Era.
Yeah, didn't their reign come to an end when a giant marshmallow hit the Earth and blotted out the sun with huge clouds of sugar frosting and cocoa powder?
Indeed. It was the most delicious ELE, ever.
Been around forever; by this point, basically means that sucking the tailpipe is cleaner than breathing the surrounding air (for the first couple years of the vehicle's operating life), except for that pesky CO2.
And lack of oxygen, for that matter.

"*PZEVs have the same standards as SULEV II, but manufacturers must guarantee that the PZEVs meet the standards for a longer vehicle lifetime--15 years/150,000 miles--plus have a fully-sealed, zero-emissions fuel system."
That's from 2007 so already a bit old, note all the bins and tiers and such beyond that. Yes, "Partial" is still silly. But "Practically," it does mean that except for the CO2 they're pretty damn clean. At the price of all the emissions generated when manufacturing the catalysts and refining the gasoline. (So when you count in all the platinum mining and oil burnt to pump and transport and do-useful-things-with oil, how much dirtier is it to manufacture batteries and rare-earth magnets right now?)
Yeah...It's pretty funny. I owned a Ford Focus, which was a PZEV and I was curious about this terminology too. Oxymoron if you ask me...The owner of a Focus, which is better to the environment to manufacture, and that has a smaller carbon footprint than a Prius (and most cars for that matter), gets no tax write off because of it's PZEV status in California. But the dealerships do - because they were (the last time I checked) required to sell a certain number of low emissions vehicles under a certain price. The owner of the Focus is also not given a carpool pass.
Part man. Part zero-emissions vehicle.ALL COP.
We have the technology.
it doesn't use the whole orphan.
I assumed that if it combined with other PZEVs, it would form one complete Zero Emission Vehicle. That was also a robot lion.
The sum is always lesser than its parts.
Like I'm going to believe you over Voltron? I'm sorry, how many universes have *you* Defendered lately?
