Reverse boxer 2 stroke???

So a buddy linked me to this. Its like a boxer motor that is partially reversed and a two stroke. Its made by Eco Motors and is they call it the OPOC (opposed piston, opposed cylinder) engine. Check it out... http://www.autoblog.com/2009/11/30/autoline-on-autoblog-with-john-mcelroy/

 

Here's another link with a little more info... http://engineeringtv.com/blogs/etv/archive/2008/07/01/opposed-piston-opposed-cylinder-engine.aspx

 

Looks annoyingly complex.

 

i can see this as a good idea for a diesel, but idk how will it would work for pump gas.
but it is a sweet idea

 

I've seen this before, I thought this was for diesel.

 

The article mentions it in both gasoline and diesel platforms. I think its an idea that has potential. I hope they continue working with it and we see a production version in the near future.

 

Thought I saw something similar in for helocopter engine prototypes.

 

I love the idea of thinking different and trying things differently. If the benefits truly are as great as they say, this ****er's got potential.

That said, it does have 8 pistons for four combustion chambers, and three crankshaft bearings per combustion chamber, which worries me. Double the piston rings and more than double the crank bearings. However, eliminating swallowed valves altogether is fine by me. One less part to break off and rattle around in the combustion chamber.

I want to see this thing in production somehow. If it has the "2-stroke powerband" where it fires on every single compression, want one already. I can already visualize this thing double stacked in a motorcycle frame...

 

There is no valvetrain, so it has half the parts of a traditional combustion engine.


Anyone know if they have an actual working prototype?

 

it said that they have one with 500 hours on a dyno
this is from the first link
Eco invited me over to Roush Industries to watch one of their working prototypes running on a dynamometer, where it's already racked up over 500 hours of test time.

 

After reading this i'm more intrigued by electrical turbocharger (more like electrically assisted), that uses electric motor during low exhaust flow (like spool-up) to rid of any lag.

I think this one's bigger than my car lol

 

Compressors can only flow so much at low engine rpm's before they surge, as we've found with the VNT Garrett. A compromise between ultimate power and low end torque still needs to be made, but you do have a wider operating range however.

 

this was posted a fair while back.. different link.. I remember.. I think I posted it and got told it was a repost... ha hah a

 

This might be a repost too, but ya'all ever see this article? Cool use of a EJ22:

I agree, a 2 stroke powerband would be pretty wicked in a car haha
