Separate names with a comma.
I generally agree with all of your comments. Regarding the “off-board†HC emissions ancillary to vehicle operations, according to EPA in...

The 2009 Jetta TDI does not use urea; it has a NOx Storage Catalyst (NSC), in addition to a DPF. To the best of my knowledge, all other T2B5...
I completely agree, and this is the main reason why I think diesel technology needs to continued to be pursued - CI appears to potentially be a...
Thanks Rob. I enjoyed our discussions at TDIClub. You've actually raised some very good points which I have found very useful. Thanks for your...
Correct - if you only had NO2 and OH in a confined space, all the NO2 would be oxidized to NO3 in about 1 day (under typical ambient conditions)....
Do you have any data suggesting these emissions are unique to diesels? I've already acknowledged that diesels tend to be higher in NOx, but I've...
The values come directly from a USEPA publication, Tables 3-23 and 3-24 ( http://epa.gov/climatechange/emissions/downloads06/07Energy.pdf )....
I consider evaporative emissions important because up to 50% of ALL ambient HCs (not just anthropogenic HCs) come from GASOLINE evaporation (...
I'm not sure what you're referring to. The CARB certs I'm referring to have 0.009 g/mi NMOG (@ UL) for the Prius and 0.012 g/mi for the LEV II...
1. I THINK it's by mass, although I'm not certain. Good question. CO has an average atmospheric lifetime about 50 times longer than HCs (although...
Thanks. Same here. I love a good discussion on emissions. :) The information I have is generic gas vs. diesel, all I know specifically about...
As far as a estimate of T2B5 gassers' PM emissions, a test conducted by the "Association of Emission Control by Catalyst" (a European outfit, I...
SageBrush - according to Fujita ( Fujita, et al, “Variations in Speciated Emissions from Spark-Ignition and Compression-Ignition Motor Vehicles...
Actually, I included several links in my original post, but I got a message that links weren't allowed until I have at least 5 posts. :confused:...
I hope the Priuschat community will allow a Jetta TDI owner to join this lively discussion. I am an atmospheric scientist and have been...
