Separate names with a comma.
Is there any technical reason why atkinson cycle (miller cycle?) can't be applied to diesel engines in hybrid applications, since the electric...
Emissions from any combustion process are harmful, including gasoline engines. IARC (WHO) knew decades ago that extracts of gasoline exhaust were...
I'm a little skeptical of this "record blocking pattern" assertion. There have been atmospheric blocks (often called "omega blocks" due to the...
There is currently a version of the 320d in Europe that is certified Euro 6 - Select a search : Directgov - Car fuel data, CO2 and vehicle tax...
Actually, a Euro 6 version of the 320d has been certified in Europe - Select a search : Directgov - Car fuel data, CO2 and vehicle tax tools ....
I agree. Based on the relative difference between the Euro-spec 320d and the Euro-spec 335d, and applying that relative difference to the...
The new BMW 3 Series diesel will be introduced (as 328d) at the New York International Auto Show later this month... BMW Concept Active Tourer...
I do recall that you said that, and I responded by mentioning that algae biodiesel is currently available commercially at a few stations in...
I guess I'm one of those gullible Americans then since I own a clean diesel vehicle. Didn't we already have a discussion about this on another...
I get my DEF at local truck stops for $2.699/gallon. DEF refill is part of the free maintenance agreement, but I've had to add a few gallon on a...
Yes, it should be. I didn't even think about that when I labeled it "HC+NOx" in Excel. But you're correct, it includes more than just...
Yes, it's actually NMOG for the gasoline vehicle. I combined NMOG/NMHC and NOx because it's combined in the supplemental FTP in the US06 and SC03...
Again, most of the diesel vehicle currently offered in the U.S./Canada are very close to SULEV. Here is the exhaust emissions profile of the...
I fundamentally disagree that emissions are a legitimate issue with diesels, ULEV/SULEV/PZEV notwithstanding. In the first place, many of the...
It seems a little premature to speculate about real-world highway mileage of the Cruze since official EPA numbers haven't even been published yet...
Have you read the IPCC AR4 report? Direct quote from that report... (Page 595) (Page 626) I acknowledge that I have not worked directly...
That reflects my experience very well. It's hard to have any confidence in climate models that the IPCC proudly proclaims can be used as NWP...
It's a shame that even EPA seems to be compelled to single out diesel exhaust as a primary source of PM2.5 when even its own data suggests that...
I used the WTW GHG results of GREET1_2012 of the MT versions of each vehicle. Using the AT versions, GREET1_2012 gives 449 g/mi (PZEV) and 384...
Here's a WTW emissions comparison of a PZEV gasoline version and a TDI version of the VW Passat... [IMG] WTW GHG emissions - 351 (TDI); 416...
