Actually, the U.S.-spec 2.0 TDI gets quite close to SULEV per certified emissions data from CARB......
That's true, but the difference isn't as great as you calculate. It's about 11% difference according to EIA...
Actually, the CARB emissions certification (http://www.arb.ca.gov/msprog/onroad/cert/pcldtmdv/2010/daimler_ldt_a0030380_3d0_u2_diesel.pdf) shows...
Depends on what it's compared to. Compared against the gasoline versions of the same vehicle (VW Jetta)......
The slightly higher tailpipe emissions of the current generation of T2B5 clean diesel vehicles (mainly in the form of NOx) are at least partially,...
Actually, I agree with you. You're correct - increased levels of atmospheric wv don't necessarily mean more cloud cover (although it generally...
POSITIVE feedbacks will, but there are also potential NEGATIVE feedbacks, cloud cover albedo being the greatest. The latest IPCC report...
The 3-day/2-day diurnal tests are evaporative emissions from a vehicle that is not occupied, i.e., while it is sitting in a garage or driveway....
usbseawolf2000 - per CARB, the conversion from the grams/test (for 2-day/3-day diurnal) to grams per mile is obtained by dividing the grams/test...
This is what the CARB regs say about this issue... " …These evaporative standards and test procedures are applicable to all new 2001 and...
They are? You must be looking at different certification sheets than I am......
That's the typical YIELD, but crude oil doesn't come out of the ground in those proportions (at least that's my understanding). According to The...
The evaporative emissions from the vehicles need to be included (they're available on the certification sheets - e.g., three-day diurnal, running...
Do you have a reference for this? I am aware of at least a half dozen research papers that demonstrate that DPF is highly effective over the...
The full article requires either a subscription or purchase of this particular article. The abstract only mentions that emissions of PCDD were...
If the source of chlorine for PCDD formation comes from the engine lub oil, then the PCDD emissions wouldn't be unique to diesel engines. Since...
I did - the RIA. Specifically section 2.2.2.7 Dioxins... The url is http://epa.gov/nonroad-diesel/2004fr/420r04007c.pdf if you want to verify but...
Yup - sorry. NOx = oxides of nitrogen (NOx = NO (nitric oxide) + NO2 (nitrogen dioxide)). HC = hydrocarbons. Refered to as NMHC (non-methane...
The issue with diesel emissions has become a non-issue with the new "clean diesel" vehicles currently being produced. The overall difference...
I also meant to mention that I conducted an 18-month study of NWP model guidance temperature projections for several forecast points in the...
