If posted before, my apologies. Feasible? Interesting engine based on old Otto type engine.

Looks pretty cool, but where do the exhaust gases go? Are they just released as the piston and cylinder come apart? If so, that would be a terribly dirty engine. Anyone have insight into that?

Nope. Something weird, though.

“The CC engine has no engine block, no crankshaft or associated connecting rods, no separate flywheel, no intake or exhaust valves and their supporting machinery, no water pump, radiator and the supporting hardware.”

Needs no catalytic converter either according to the site

Notice on the main page the entire unit is enclosed with what appears to be an exhaust manifold at the bottom.

Interesting concept. Hate to be using one in a vehicle if timing screws up. Would like to see some independent reviews from engineers

The zenith of the internal combustion engine was reached in 1955 with the invention of the Small Block Chevy. It’s not just about efficiency, but also about ease of manufacture, cost, reliability and suitability for use in mass produced automobiles. Ultra high tech and fuel efficiency are not substitutes for all of those things. So what if a modern engine goes twice as far on a gallon of gas? It costs 10 times as much!

Thought the same and the contraption nearly bankrupted Mazda.

We should drill drill drill and then bring back the 426 Hemi when gas goes back to $.28 a gal.

Sure, but even being encased I don’t see how they keep the clean intake air separated from the dirty exhaust air.

Watching the video of the engine running on propane was pretty cool, though.

Resembles the "Wankle Engine" ... circa 1970's ...



Wikipedia:

The Wankel engine is a type of internal combustion engine using an eccentric rotary design to convert pressure into a rotating motion instead of using reciprocating pistons. Its four-stroke cycle takes place in a space between the inside of an oval-like epitrochoid-shaped housing and a rotor that is similar in shape to a Reuleaux triangle but with sides that are somewhat flatter. The very compact Wankel engine delivers smooth high-rpm power. It is commonly called a rotary engine, though this name applies also to other completely different designs. It is the only internal combustion engine invented in the twentieth century to go into production.[1]

The engine was invented by German engineer Felix Wankel. He received his first patent for the engine in 1929, began development in the early 1950s at NSU, completing a working prototype in 1957.[1] NSU then licensed the concept to companies around the world, which have continued to improve the design.

Thanks to their compact design, Wankel rotary engines have been installed in a variety of vehicles and devices including automobiles, motorcycles, racers, aircraft, go-karts, jet skis, snowmobiles, chain saws, and auxiliary power units. Perhaps the greatest proponent of the Wankel engine has been the Japanese company Mazda.

"Then there was Vega.

We're discussing engines, not car models, but since you mention them, the Vega is what you get when all of your designers and engineers have retired and the bean counters and corporate brass design a car. As for the Volt, that's what you get when the government drives the entire design of a car.

Alas for Chevy!

Can’t easily see the advantage of this design.

It still is a reciprocating engine for starters.

It looks very interesting but there looks to be so many critical wear points that maintaining alignment and fit might be nearly impossible for very long.

For example, what seals the piston inside the cylinders? That piston must have perfect alignment as it enters the cylinder and contend with side scuffing and maintaining inline position until it leaves the cylinder. What is a tiny bit of wear going to do to the fit?

I was also thinking about the timing...Henry Ford was obsessed with his design of the “X Engine”, an 8 cylinder with 2 cylinders transposed to each other in an X ...the timing killed it.

It still is a reciprocating engine for starters.

Without rings, and without an obvious way to circulate coolant (and a commercial automobile engine would require cooling).

And the most obvious drawback: the "engine" itself is rotating. That's a lot of mass for quick acceleration, and would detract from brake specific fuel consumption.

Some early aircraft radial engines were designed for the engine itself to rotate.

Never caught on.

A little mis-alignment and I think you would come to a sudden stop.

And the engine would disintegrate. You have to wonder about failure modes.

It certainly is an interesting design.

I can't help comparing the Vega to the Chevy II. Now there was an excellent small car. Available with a 327/350 it would embarrass many larger muscle cars. Compare the Chevy II/Nova to the Vega and you realize that a car is its engine, with none more wonderful than the SB Chevy.

What is a tiny bit of wear going to do to the fit?

They address that in two ways it appears.

There are no angular forces pushing the piston against the cylinder walls eliminating the frictional losses of crankshaft engines. The compression/combustion forces are directly in line with the piston/cylinder centerlines. (See illustration “A”)

In the CC Engine there is clearance between the cylinder wall and the piston to allow for any thermal changes and component wear, there is no lubrication needed on the cylinder walls. The piston-cylinder pressure seal is in a cartridge located at the entry of the cylinder and allowed to float within the limits of piston-cylinder clearance.

That compression ring cartridge is a really interesting concept. The piston never actually touches the cylinder walls. The cartridges might actually be pretty easy and (relatively) inexpensive to replace. But they might not wear that much anyway.
