Use alternators as the rotary dampers instead, and generate electricity at the same time.

Does anyone have more info (specs or animation) for the Beindl twin crank engine? In particular, an animation showing rotation direction?

I'm interested in learning more about this engine in the single cylinder gas na form. (Most of the information is concerning the twin diesel version.) I've read that the 650cc single was producing 115 bhp. Coincendently I also believe that particular engine to be the one fitted with the intake ports coming into the combustion chamber directly vertical and between the two cams. I've spent much time pondering what I believe to be the novelty of this port configuration, but can attribute the high output to fair breathing in combination with the merits of the twin crank assembly.

The following quote is taken from an essay (http://www.pacifier..../disruptive.htm) by Robert S. Cascaddan

As a result of offset cranks, the intake and power strokes in a twin-crank engine take more degrees of crankshaft rotation to complete than the compression and exhaust strokes. The Bike article specifies advantages for each stroke. The intake stroke is longer, so there is more time to draw in air/fuel mixture and cool the piston crown. The compression stroke is shorter, allowing less time for heat to transfer. Also, higher piston speed results in more turbulence in the air/fuel mixture. The power stroke is longer, allowing more time for the expanding gas to push on the receding piston. The exhaust stroke is shorter, resulting in higher exhaust gas speeds and more effective exhaust tuning[4]. The result, particularly when combined with a higher redline, is more horsepower.

The rods come towards each other on compression then straight down after ignition.

An Interesting Thread.

High Power Density Engines


Since the rules have hobbled all my interest in racing car power-plant development. I note significant work is being done in the UAV Aero-Engine world.

Even Cosworth have become Involved.
http://www.cosworth....etail.php?id=54

Ilmor have have also produced the engine for the Meggitt Voodoo UAV, a development of a Triumph Motorcycle engine


To prove that there is not much new under the sun more information can be found here.

Some unusual engines. LJK Setright. Imech E

• ISBN-10: 0852982089
• ISBN-13: 978-0852982082


“And I quote.”

WHY I LOVE....

“I am charmed by the original compressed-air rotary engine of Hargrave, as by the dainty Gnome and other rotaries that took the air up to 1918. I am captivated by the 1966 five-cylinder 125cc racing Honda, safe to 24,000rpm and knock-proof on 85 RON petrol. I feel profound respect for the utterly simple solid-fuel rocket engine, blasting into space with a rapidly lightening load of solid rubber and aluminum dust.

Yet nothing that I know can unseat the overwhelming fascination inspired by the prodigious Napier Sabre, surely the most brilliant, most maligned, most iconoclastic, and most ferociously competent piston engine of all. Use the latest technology to make an engine like that now, and what marvels might ensue!”


LJK Setright



But Setright may have never seen this;

The Meyer Nutating Engine

Posted Image



Outrageous claims from the US Air Force Research Labs.

“The Meyer Nutating Engine is a new type of internal combustion engine with higher power density than conventional reciprocating piston engines and which can operate on a variety of fuels, including gasoline, heavy fuels and hydrogen. This engine has unique advantages over conventional piston engines and gas turbines in small power ranges (10 to 500 kW) suitable for Unmanned Aerial Vehicles (UAVs), ground vehicles, marine applications and power generation. The engine features a nutating disk that has the most volume displacement per engine size. For the same engine size and weight, this engine produces twice the power of a 2-stroke piston engine and 4 times the power of a 4-stroke piston engine. In addition, multiple disks of unequal size can be used for intake and expansion, resulting in distinct and significant power, thermal efficiency, fuel flexibility, and arrangement advantages over conventional piston and small gas turbine engines.”


The principal has been used for pumps for some time; Modern use includes medical pumps and flowmeters etc.

As an IC engine it exhibits many advantages .

1. Capable of use with a great number of Thermodynamic cycles.
2. Only one moving part.
3. Spherical compression and expansion volumes for minimum surface area per unit volume
4. Minimum sliding friction.

Perhaps some of the effort that was being expended on getting to the start faster will find some outlet in this field.

I would welcome some comments.

From the NASA report: conclusions

"The Intake/Compression and Power/Exhaust modules were
connected and briefly tested as a complete engine.
Unfortunately, by this time, the allocated resources of the
Phase II SBIR contract had been depleted. Limited testing
verified that the engine self-sustained, but no performance
data were taken."

Well I've just been wiki-bashing the same report.

Q What works at a circus and balances a ball on its nose?

I'll admit, in the last 30 years we've got lazy. We expect piston rings to work. For hundreds of hours.

They wore the thing in, and then out, just running it as a compressor. The power to weight ratio is a bit hohum compared with off the shelf UAV powerplants.

Efficiency could be anywhere. Given that no numbers are quoted, I think I can guess what it'll be. I don't see a huge efficiency advantage compared with say the wankel, and we all know what that was like.

Power/packaging volume could be good, and that is a good attribute.

Nice find. I'll have to look at the thermo stuff

Two power strokes per crank revolution. :rolleyes:

Fewer moving parts; less friction; higher reliability. True, unproven,unproven but possible

Expansion volume can be greater than intake volume for increased power and efficiency (sea-level applications). Atkinson. Not very hard to do is it?

Compression volume can be greater than expansion volume for "self-supercharging" high-altitude applications.
Anti Atkinson.

High Power Density Engines

I agree with a healthy scepticism of new engine concepts. But this Nutating concept may well prove worthy of much more effort.

All of the references you will find on the web are over 2 years old. There is a lot of effort being expended in this field at the moment.

Some further Heavy Fuel work is being done by Greg Stevenson Engineering in the USA.



He may even have begun a recreation of the Napier Nomad.

I do hope this provokes more comment.

I don't see why sealing the combustion chamber should be very different from piston engines. It's not like a wankel with it's combustion chamber walls that change angle WRT the rotor edges.

Think about how many seals there are. I count something like 30 feet of seals in a 10 inch rotor, in the Meyer paper.

That seems to me to be the biggest weakpoint. I'm also rather suspicious of the efficiency claims, due tot he huge surface area, although Mcmasters claim that much of the combustion chamber can be insulated, which is good for thermo.

However, it obviously can be an inherently low friction design, which is a good place to start.

I believe you nailed it.

These wiggle-plate engines have been kicking around these parts for a while. The Meyer engine was built under contract by a shop in Michigan that specializes in oval track engines. I am not sure it ever ran in that form. The McMaster engine is the Harold McMaster who developed tempered auto glass, made zillions. That deal became Guardian Industries. Salt of the earth, super nice guy, endowed a half-dozen universities around here. Was also way into solar power, he either bought or came up with cadmium-telluride. that's him too. But he passed away a few years ago, at which point the engine project stalled out it would appear.

Not me. He was a great man. The entire Physics complex at the local state university is named after him, which they would have done even if he hadn't endowed it. Several schools in the area have similar edifices in his honor. Nice man too. He always loved to talk about old Buicks... or maybe he just thought I did.

I think there is a fair bit of life left in the gasoline engine, and I've always had a lot of time for boxer engines, both from a packaging and vibration point of view. However, running two cylinder heads and two cams is a bummer.
