Jon, No numbers for you just concepts. Most fuel injection engines run about the same. It is the Cat that scrubs out the pollutants. The nuber of valves an engine has also helps clean thing up a bit. New engines have a new rating of low emission and ultra low emission largely do to the newer controls. None of this will change the amount of co2 emission. Long and short of it is that the larger the engine and the larger the vehicle the more co2 will be emitted and this is where I might begin to draw a line on ethics. If you drive a bigger vehicle than you need to do the job than you have crossed the line. I really doubt that you will go to hell just make the earth more like hell. regards gary Date: Sun, 29 Aug 2004 12:41:46 -0400 From: Jonathan Farrugia <jfarrugi@UMICH.EDU> Subject: emissions data given all this talk about emissions i am interested in getting some emissions data. i have always generally considered that the new the engine the better the engines emissions. hence the california swap regulation that you can swap in a new engine but not a older engine. so i would like to find out the emissions of several model years and makes of volkswagens. i have no idea where to acquire this data. i assume the epa site might have the data some where or it could be in an emissions test manual or book. i have always figured that engine swapping with NA approved engines from later model cars was a good way to improve my vanagons emissions. i would like to see how much better my actual emission should be. i would like to get data for the following years and makes of volkswagens. thanks for what you can contribute.
