I deleted "by modifying the Carnot Cycle." Carnot never built an engine; his Cycle describes the ideal cycle for a heat engine (including steam, diesel, Otto, Rankine, or Stirling). I also deleted
"Joseph Cugnot, who crashed his steam-powered "Fardier" against a wall in 1771,[2] "
since it's disputed Cugnot's vehicle ever ran.
This comment is not coherent with the information published here : http://www.drire.gouv.fr/ile-de-france/vehicules/homolo/cnrv/histoire.htm, nor is it coherent with numerous relations of the facts that Cugnot built two socalled "fardiers", which are reported to be around 2500kg heavy and effectively ran for respectively about a mile (a quarter of an old French "lieue" which is about 4 kilometers) and about three miles (5 quarter of a "lieue", as described in the report made in 1770). The fardier is still kept and can be seen in the museum of the "arts et métiers" (trades and arts) in Paris.Zolegd (talk) 11:35, 3 January 2009 (UTC)
Also, the article says "11,450 lbs of carbon dioxide"; over how long? I added
"Its disadvantages include poor heat efficiency and extensive requirements for electric auxiliaries.[3]"
and
"This makes clear the often-ignored fact road design and traffic control also play a part in car wrecks; unclear traffic signs, inadequate signal light placing, and poor planning (curved bridge approaches which become icy in winter, for example), also contribute."
The last is something I'm unsure really belongs here, but there was an implication all car wrecks can & should be blamed on driver error or bad car design, which is clearly untrue. Trekphiler 02:39, 12 April 2007 (UTC)
Under 'Fuel and Propulsion', 'Diesel' it says that diesel engines have a 50% burn efficiency compared with 27% in the est gasoline engines. The source is from 1988, and recent technological advances have been huge on both the diesel and gasoline engine, and it seems to me that these would have change over 20 years with the advances in fuel economy. —Preceding unsigned comment added by 131.111.8.99 (talk) 22:50, 2 May 2008 (UTC)
I'm not a car expert, but I must note, that engine efficiency and vehicle efficiency are two very different topics of interest.Fuel economy, Fuel efficiency in transportation, Fuel economy-maximizing behaviors, Fuel efficiency, Fuel efficiency in transportation, Low-energy vehicle bkil (talk) 23:14, 22 November 2008 (UTC)
