EcoMotors OPOC diesel engine explained

Eurocopter has revealed it is evaluating the potential for powering a light helicopter with a unique diesel engine developed by US company EcoMotors. A diesel engine could reduce fuel consumption by 40% over a turbine engine, and EcoMotors' Opposed Piston Opposed Cylinder (OPOC) engine is claimed to be significantly smaller, lighter, simpler and cheaper than conventional diesels. In this video, EcoMotors chief technology officer explains how the engine works.

an aircraft version?????

is this guy smart or what

@Philscbx If you can get enougn air to flow through the engine on the uniflow intake cycle, (Air comes in above the lower piston and chases the exhaust out above the upper piston), a 2-stroke like this can be as clean as a 4-stroke.

Note the mention of being 'able to achieve boost pressure even before cranking (starting) the engine'. Intake air management and turbochargers have come a LONG WAY since the 2-cycle GMC diesels designed in 1938!

-It already dominates. Think about the container ship engines, which are uniflow scavenged 2-stroke diesels and the best of them has the measured efficiency of over 50 %.

Yadaa Yadaa Yadaa .........Give it a chace to be.......It just might . Henry Ford would have Loved it. I do.

The only reason seizures are famous in 2 strokes is because not many people run them tuned correctly. Tell me more about the potential issues with the outer piston wrist pin locations? Also, i'm unsure how you can spot a cooling issue when they didnt even illustrate the cooling system.

Quote from an interview of CEO Don Runkle of EcoMotors:

“The OPOC is cheaper, better, simpler, stronger, lighter and cleaner than any other power generating technology now or in the foreseeable future. . .The engine’s width is exaggerated a bit . . .”

Yet, the pattakon opposed piston engines OPRE and PatOP (there are videos and video-animations in the youtube) are cheaper, better, simpler, stronger, lighter and cleaner than OPOC. Aren't they?

I have to admit it's a cool layout, but two stroke will never dominate 4 stroke for fuel efficient right out of the box.

Other than GM's diesels. Mercury Motors?

Maybe a stand alone powerplant for generator out in the jungle where the epa is out of site.

Integrity, the equivalent of 200k miles, Doubtful.

I see issue with outer pistons wrist pin location.

I'm sure they do as well.

Cooling issues see partial seizure as 2 strokes are famous for.

Brushless turbo boost looks good.

Good Luck.

Forget the conspiracy theories. Batteries are just not ready for prime time. In fact what really killed the electric car was the perfection of the starter motor, ie ease of starting and long duration.

if they could use transonic supercritical fuel injection on this it will icrease efficiency even more, check it out at transonic combustion, wonder if it would work?
