The german article is about an engine and this article is about a vehicle, its on my todo list to create an article about the engine. Mion (talk) 11:31, 10 March 2009 (UTC)

Kind of low improvement[edit]

The power output of a direct injected hydrogen engine vehicle is 20% more than for a gasoline engine vehicle and 42% more than a hydrogen engine vehicle using a carburetor[2][3].

20% ? seems very little, TCEV is 30-40% efficient, gasoline ICE is only 20%, increase is thus 50% —Preceding unsigned comment added by (talk) 05:49, 14 August 2009 (UTC)

& as well from Kenya Patrick Murage Karuku have improved the cooking system with hydrogen. —Preceding unsigned comment added by (talk) 16:34, 29 December 2010 (UTC)

Low Emissions[edit]

I noticed the "low Emissions" section says, "when a hydrogen fuelled engine is tuned for greatest emissions it produces emissions equal to a gas fuelled car from 1976" (I paraphrase). What about when tuned for minimum emissions? Doesn't this wording and lack of minimum emissions info seem slanted against hydrogen cars? — Preceding unsigned comment added by WertMooMoo (talkcontribs) 08:07, 5 June() 2014 (UTC)

well, if you read it possitive, the test was done in 1976 and compared to 1976 emissions from regular gas engines, and it states that you could get the extra power output from hydrogen and maxed in emissions it wouldn't be higher than that from gas engines. Aldo you would go for the minimum emissions from an environmental point of view, economics would demand that you try to max power output of the engine, the maxed emissions is a worst case scenario for modelling, in practice you have less emissions.

Reference 11 on fuel cell vehicles[edit]

Reference 11 directs to a site (not a PDF) of the US government about, among others, fuel cell vehicles and not about combustion engine vehicles. Besides that I cannot find any numbers on output power.

Besides the above mentioned, I think it would be worth mentioning the usage compared to the extra output power. — Preceding unsigned comment added by Al126 at wiki (talkcontribs) 12:47, 6 April 2015 (UTC)
