Wonder if Subaru has taken a look at this new boxer engine design. Pretty cool!

 

 

Be sure to watch the little video on the engine!

 

 

 

 

 

New Engine !

 

Saving the World Two Strokes at a Time

 

 

 

This is no wimp engine. It's a two cylinder with four pistons delivering 300+ Horse Power. It's extremely small and very efficient and is presently in use in test applications. The configuration below is equivalent to a extremely ballsy four cylinder engine. When doubled, it's an extremely ballsy 600+ H.P. engine

 

 

 

It’s called OPOC (Opposed Piston Opposed Cylinder), and it’s a turbocharged two-stroke, two-cylinder, with four pistons, two in each cylinder, that will run on gasoline, diesel or ethanol. The two pistons, inside a single cylinder, pump toward and away from each other, thus allowing a cycle to be completed twice as quickly as a conventional engine while balancing it's own loads.

 

The heavy lifting for this unconventional concept was performed Prof. Peter Hofbauer. During his 20 years at VW, Hofbauer headed up, among other things, development of VW’s first diesel engine and the VR6.

 

The OPOC has been in development for several years, and the company claims it’s 30 percent lighter, one quarter the size and achieves 50 percent better fuel economy than a conventional turbo diesel engine.

They’re predicting 100 MPG in a conventional car.

I remember reading or hearing about this engine some years ago (and by some, I mean sort of recently).

 

Glad to see someone is interested in it. The US Army is definitely a great start for such an engine, however, getting it into passenger-car use is certainly going to be a great challenge.

Definitely an interesting idea. It'll take a hell of a lot of thought and design to get it in a passenger car though.

 

Those extra-long connecting rods kind of freak me out though.

Very interesting post. While not Subaru specific, it makes one think in depth and also to recall that early steam engines' designers grapelled with similar issues. The post was written so well I could actually see it. This is something to watch and if dear Japan wasn't in such turmoil now..-well even if they are , their engineers are looking at this. I don't need tell anyone here that brilliant designs of before relied upon mechanical feedback. The advent of electronics to govern IC engines of remarkable design..

What I'm saying is truly brilliant engineers existed long before this time and had designs over designs but worked up to a Wall of sorts. They knew metallurgy and coefficients and everything which we still deal with. We now have the electronic brains which was the missing link.

This design would likely not be allowed in US market vehicles if it ever makes it into an automotive application. The EPA would ************ a brick because it.

There is a reason 2 stroke engines are not allowed in highway use vehicles.

This is far to great of an idea and would work too well. the government and oil companies will simply not allow it.

A direct-injection gasoline 2 stroke would not blow fuel out the tailpipe, would probably need to be supercharged.

 

There are some opposed piston diesels out there, and I think there was even a german WWII bomber with an engine like this.
