VW emissions test

Hmmmm, please do elaborate... thx

Let’s see, where to start… This may start to get off topic, but people have a tendency to lump ALL emissions together, when in fact they have completely different impacts and are regulated differently. The pollutants that form photochemical smog (the dirty brown haze on a hot summer day in Bakersfield) lead to adverse health impacts as well as other issues. These pollutants (eg. NOx, volatile hydrocarbons, CO, etc) are commonly referred to as criteria pollutants. They’re typically controlled by pre and post combustion control equipment dating back to 60’s(?) (EGR, catalysts, DPFs, low sulfur fuels, urea injection, etc). Requiring cars to burn ‘cleaner,’ reduced this smog formation, and has had a huge positive impact in areas such as the southern central valley California and the Los Angeles region.

GHG’s on the other hand are ‘believed’ by some to cause climate change (longer-term pie in the sky type ****). The way government primarily started regulating control of these was to require manufacturers to make cars more fuel efficient (while maintaining current criteria pollutant controls.) I think the last part is where some people get confused. The government just isn’t going to allow manufacturers to disable control devices that provide 95-99% control efficiency of pollutants that are known to produce smog and associated negative health impacts, even if it reduces GHG emissions by doubling fuel mileage. That’s the reason why fuel efficiency standards are so challenging to automakers. It sucks, but I guess it is what it is.

??? So, VW 'certified 2015 EPA test vehicles' (read sample test units pass emissions criteria = rubber stamp total build units) of course could not have the slightest inference to the Honda Motor Company
bait & switch game of the late '90's???

Just asking Sir.


I’m not quite sure what you're asking.

Either way, have a good weekend. Time to mow the lawn and grab a cold one. :glasses7:
