Lotus Omnivore engine Phase 1 testing

We've been covering the Lotus Omnivore engine--a flex-fuel concept that can burn any blend of gasoline or alcohol--since the project was unveiled in 2008. Today, Lotus Engineering released an inside look at the technology by way of an interactive animated video.

The idea of burning multiple types of fuel in a car isn't new--GM and other carmakers have had flex-fuel vehicles on the road for years now. But doing so efficiently is a whole other challenge. Last December, we brought you word that Lotus had figured out how to make its Omnivore engine up to 10 percent more efficient than a state-of-the-art direct-injection gasoline engine thanks to the use of a two-stroke cycle and a variable compression ratio.

The variable compression ratio works by using a puck in the cylinder head to optimize the fuel burn. The system can go as high as a 40:1 compression ratio. That's a sky-high figure--a typical modern engine lies somewhere between 10:1 and 13:1. But it lets Lotus cram more air in with the fuel to get the most out of every drop, no matter what ratio of alcohol or gasoline that drop's made of.

Check out the interactive animated demo below to learn more about the Omnivore engine concept.

  1. CD Shoes, is that a metaphore or an ad?
    However,
    Motor Authority, your article about the omnivore engine technology is by far my favourite (compared to other automotive sites...).
    I think Lotus is on its way back to its glory days. I'm expecting a lot from their upcoming models.

    Bad stuff?

  2. And why does it have to be two-stroke?
    Consider one of the three VCR in pattakon web site. They all fit to both, two and four-stroke engines.
    If you prefer the two stroke, the OPRE (pattakon web site) direct injection can be combined to the patcrank VCR to have it all.
    Better consider the case a conventional V-8 gas-guzzler is modified to a V-8 patcrank VCR.
