Availability section contains inaccuracies. Combustion temperatures are generally higher on diesels, although gasoline direct injection can approach those high levels. Talk of non-existent NOx aftertreatment on diesels is nonsense (look at any US2010 or Euro V certified heavy duty engine and the vast majority have highly efficient SCR catalyst systems). This article needs the input of some engine experts.81.106.218.66 (talk) 13:25, 22 December 2010 (UTC)[reply]

Sorry, but you are wrong.Combustion temperatures on diesel engines are considerably lower than those of gasoline engines. — Preceding unsigned comment added by 217.91.8.241 (talk) 14:41, 26 July 2011 (UTC)[reply]
