OPOC Engine designed by Eco Motors

A promising looking engine that is 25% the size, 30% lighter and 50% better fuel economy than a conventional turbo-diesel engine.
The OPOC engine was designed by Peter Hofbauer, who spent 20 years at Volkswagen designing diesel engines and the VR6

If the hype is to be believed, this would be the single most important development in ICE technology since the first ICE was fired up.

why is it only 5 seconds? Fucking ridiculous

This moter is turbo and supercharged. At my shop we are making the tubing for bolth and the mounting brackets. This thing is gonna make some serious power

Nice. I can see see where the weight ans size savings come from, but it is not clear where the 50% increase in efficiency comes from. Could you please expand on this.

Interesting concept, I don't think it'll ever be put in production, though. If it is ever put in production, I don't see it being used in an automotive application.

@mrriteubthejudge sorry i see it in another video.

the outside piston has to have a conecting rod on both sides of it or it will want to try and twist everytime it fires

From what I can tell, it looks like they took a couple of old concepts and one new one and put them together in a very interesting configuration: opposed piston (old), opposed cylinder (old), electrically assisted turbo for constant boost across an RPM (and temperature) range (new-ish.) Would be very vibration resistant (I like) and small for a diesel. I think I read of this years ago, though. Whatever became of this? Why is this not on the market? Did the reality not end up matching the theory?

The british Napier engine company were keen on opposed piston engines in the 50s. Check out their Deltic locomotive and fast patrol boat engine.

Increased surface area too capture the combustion pressure, now make it 4cycle , super low rpm's like less than 50 , micro-pyramid hemi-pistons , and a great turbo ; blueprint and balanced with no decitful engineering flaws and hook it up.

@r8wing I totally agree. Don't forget the Commer TS3 btw.
