December 31st, 1969 Nearly every major carmaker in the world is working on some sort of alternative combustion engine technology, be it ethanol or hydrogen fuel, advanced diesel engines or the advanced hybrid petrol solution known generically as HCCI (Homogeneous Charge Compression Ignition), or as Mercedes has branded it, DiesOtto. The basics involve use of diesel engine principles in petrol-fueled engines for a combination of greater power output and fuel efficiency than either traditional petrol or diesel solutions. In this video, Dr. Günter Karl explains the process in detail, with the aid of a cutaway engine. As Dr. Karl points out, the technology is currently still in the experimental stages. Test engines have been fitted to a number of cars, however, including the F700 concept and an S-Class, the latter achieving 39mpg (6.0L/100km) and 238hp (175kW) from a mere 1.8L engine. Two-stage turbochargers, direct injection and controlled auto-ignition make for a very interesting use of four minutes.

    Fascinating technology, but why are German scientists so difficult to listen to?

    Difficult? I think they're funny :)

    Yes, I can already see this techonolgy helping to decrease a number of diesels in Europe. And that is ok, I prefer clean petrol exhoust over diesel smoke screen.

    Gus - they could say the same about some 'mericans :)

    Very true.
    And don't get me wrong, I speak fluent German, but somehow that droll, German monotone just makes me want to slap the guy and say "come on, get excited, this is groundbreaking stuff here!!!"

    Please don't think all Germans talk like that. :D Sometimes I think German companys WANT people with that "typical German" accent (and way of speaking) for image matters.
