EPA to Propose Tougher Tailpipe-Emissions Standards

It sounds like a good idea for the planet, but a bad idea for the consumer. Fuel efficient vehicles usually cut some corner like low tension piston rings, ultra thin oil, etc that can prove to be a headache for the car owner down the road.

The government has shown it doesn't care if the consumer pays more for their regulations.
And where is the "no spin" cost/benefit analysis for all the changes since the 90s.
 
Interesting...

None of it is for the planet.

We past the tipping point for real economy about 25 years ago....maybe even longer.

We are now into tin cans and plastic transmissions.

My 1982 VW 1.7 gas Jetta would consistently get 38mpg. Bosch Jetronic mechanical fuel injection, I loved it. That was 41 years ago....how far have we come?
 
I wonder what this will mean?
Will everything have to be SULEV, or we're going straight to PZEV across the board?

To all the bellyaching and boomer bitching I see further up the thread, I assume you were all complaining when

  • The PCV valve came into use in in 1961
  • The EVAP canisters of 1971
  • The catalytic converter/HEI setups of 1974
  • The OBD setups of 1988 (OBD2 in 1996)

Time stops for no one, and clean air is important
I do agree with the concerns of planned obsolescence, at least in my part of the country, cars rust out before they expire emissions wise

I want to track down a shop that still has a gas analyzer/rolling road setup, I'm curious how some of my vehicles are doing emissions wise, compared to the standards when they were new

NY deleted the dynamometer/gas analyzer part of the inspection in 2011, everything pre 1996 gets a visual emissions and safety
 
The OBD setups of 1988 (OBD2 in 1996)

Even prior to that. My 1984 Cavalier has a check engine light capable of blinking out codes, and an ALCL data stream capable of sending sensor readings.

Every emissions testing station in Northern Virginia still has one (they are private shops). I've read that they get used when a vehicle fails the roadside emissions test (Virginia DEQ is probably aware of all the ways to cheat an OBD-II only test--the emissions testing systems have cameras to take pictures of both the operator AND vehicle under test as well), and I've been told that the system will sometimes have them do a dyno test on a vehicle in addition to the OBD-II test.
 
What if cars were running on straight ethanol E100, would they need catalytic converters? Would there be any pollution?
If cars were running solely on straight ethanol E100, there would still be some pollution, but the emissions would be significantly reduced compared to gasoline-powered vehicles. Ethanol is a renewable fuel that can be produced from various sources such as corn, sugarcane, and other agricultural products, and it has lower emissions of harmful pollutants such as carbon monoxide, particulate matter, and volatile organic compounds than gasoline.

However, catalytic converters would still be necessary to further reduce emissions of pollutants such as nitrogen oxides (NOx). NOx is a harmful pollutant that contributes to smog and acid rain, and it is produced when the temperature inside the engine exceeds 2500 degrees Fahrenheit. Catalytic converters help to reduce NOx emissions by converting the NOx to nitrogen and oxygen gases that are harmless to the environment.

Therefore, even if cars were running on straight ethanol E100, catalytic converters would still be necessary to reduce NOx emissions and meet the emissions standards set by regulatory agencies. However, the use of E100 as a fuel would significantly reduce the overall emissions of harmful pollutants from cars.
