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?

[brivette]

wankel?

[Figment]

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

[taildragger]

To many parts, Check out the Erickson and their patents ( even a 2 stroke variant ).

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!

Build a working prototype and get back to me.

Neat

[DJ MacWoW]

I think one of the great problems we have in the Republican Party is that we don't encourage you to be nasty. We encourage you to be neat, obedient, loyal and faithful and all those Boy Scout words, which would be great around a campfire but are lousy in politics.

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.

I am kind of following these guys, who are developing a new kind of steam engine. Don't know if it will succeed, but they seem to have some intrest in standing waste heat recovery applications.

Wait until the manufacturers of the Orgasmatron see the illustrated engine at work.

[Balding_Eagle]

Can’t easily see the advantage of this design.

It still is a reciprocating engine for starters.

[count-your-change]

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?

[gorush]

Very interesting and brilliant. Thanks for posting!

That’s a Wanker engine Beavis. You have to crank it manually.
Heh heh heh uh heh heh

[Mr. K]

what if an engie like this was used to generate electricity to store in a battery in nd electric car.

You still feill it up on gas, but the tires are all driven by small electric engines

I am thinkit it would a nice lightweight vehicle
