The certified NOx emissions from VW's 1.6 liter gas engine in 1973 (earliest available) was 3.0 g/mile (the highest NOx emissions recorded in the...
I'm still not convinced of that. Paris apparently has many two-stroke mopeds which have very high emissions ("asymmetric pollution") relative to...
Bob, There is some information on sources of anthropogenic NOx in California (albeit a little dated now) at...
"...Particle concentration from DPF equipped diesel engines were found to be the lowest, while GDI and 8-cylinder PFI engines had the highest...
I think it's a data entry issue. There's only one 2.0 liter diesel engine available in BMWs, including the X3 28d. According to the CARB certs,...
The same study that prompted the EPA/CARB investigation (ICCT/WVU) found that all other regulated emissions were well below regulated levels in...
According to their methodology (http://www.greenercars.org/sites/default/files/file_room/2015methodologyupdate.pdf), default values of the GREET...
There has been some work on compression-ignition (diesel) engines using gasoline as the fuel. Preliminary tests indicate fuel consumption of 175...
There was a study conducted several years ago (2008) showing that rising particle concentration (from anthropogenic pollution) initially causes...
I'm not sure of the exact percentage (probably variable), but much of the water does remain in vapor phase in clouds. Another interesting fact is...
New paper (11 June 2015) disputes "dry gets drier, wet gets wetter" claim. Assessment of future changes in water availability and aridity -...
Bob, It's been my experience that high thin clouds decrease diurnal max temps (daytime high temps) much more than they increase night-time min...
In the September 2014 issue of the Bulletin of the American Meteorological Society (BAMS), there was a compilation of papers published entitled...
I did, the U.S. (three examples). Do you think the U.S. has some vested interest in diesel cars?
There are "real-world" tests of petrol cars that are not so good also. For example, a presentation at the U.S. EPA Workshop on Ultrafine Particles...
Rats and mice have been used in inhalation studies as long as I can remember. LD50s and LC50s are all based on rat/mice inhalation studies. It...
By the way, I think it was GC who provided a link that showed engine-out gasoline exhaust (i.e., non-functioning cat) had 50 times more carbon...
Concentrated diesel exhaust was not able to cause cancer or any of over 100 other heath effects after 80 hours/week exposure for 30 months.
The test cycle used was a "real-world" 16-hour test cycle especially designed for the Advance Collaborative Emissions Study (ACES), not the test...
If diesel exhaust of CURRENT diesel vehicles is so "toxic", why did lab tests show that rats exposed to diesel exhaust so concentrated that it had...
