850 HP/840 ft. lbs & 150 MPG

With all the talk of gas prices, I found this announcement interesting. This engine manufacturer claims the following with their latest design:

# of Cylinders: 32 (can be doubled to 64)
Bore/Stroke: 76.2/95.25mm
Displacement: 13.8L (848 ci)
Compression Ratio: 25:1 (can be as high as 60:1)
Cooling: Oil Cooling
Lubrication: 5 Quart drysump
MPG: 150 NA
Fuel: Bio diesel
HP: 850 NA / 3,000+ SC/TC
Torque: 840 ft. lbs. NA / 4,000+ ft. lbs. SC/TC
Rotation: CCW/CW

All of this is pretty amazing, huh? It gets even better. Here's the "punchlines"...

1. During a "dyno run", this engine had an output of 134 HP and 814 ft. lbs. AT 868 RPMs.

2. There are no "high tech" or "exotic" materials use in the construction of this engine.

3. Engine Dry Weight (including flywheel): 150 POUNDS

4. Overall Engine Dimensions (not including FI or exhaust headers): 14 INCHES CUBED

5. This engine can run on the following fuels:

Compression Ignition - Diesel
Spark Ignition - Gasoline or Alternate Flexible Fuel
Incinerators - uses 70 % garbage for fuel

Torque peak under 1k rpm? Not much of a power band... I wonder what the usable power range or torque curve looks like?

It would take one hell of a clutch or torque converter to make that design usable, but I'm sure someone would figure it out if they were incented properly... like our current HIGH FUEL PRICES!!!

Hopefully who ever snaps this up for future development actually does something with it rather than locking it up in a warehouse in throwing away the key.

That wasn't the peak! The peak torque is ove 840 ft lbs!

Yeah, but only at around 850 rpm.

Check out the dyno chart... peak tq for this run was 814 at 856 rpm, with 133hp. Now *that's* some funky numbers!

And it appears to run on air... 150psi of it... I wonder where you get that from... Gonna strap a 60-gallon Campbell Hausfeld compressor on the back of that daily commuter?

I would think you would need to use a hydrostatic drive type system.
With a hydraulic motor \ planitiary gear setup on the rear wheel, the gearing is infinite and you would have a two speed rear hub. The engine wouldnt need to rev because of the varriable displacement pump. The more volume the more speed and the more pressure the more torque.
It could be a hot seller if the performance was better than current inline 4, and the price was $15,000.

Interesting to ponder.

I'll believe this when I see it... lots of people make increadible claims. Would be cool if this thing was real, but sounds too good to be true.

BTW - looks like the engine needs an forced air induction system? I think that would increase the weight of the engine - and possibly reduce its efficiency??

Yeah - this thing appears to runn off of compressed air... so what they are showing is really only 1/2 of the whole powerplant.

I'm sure we'll hear more if there's really anything to it. Heck, the patent is already 2 years old... this thing can't be that incredible if this is the first word that's getting out.

They are testing the concept with compressed air and the low rpm is just to validate the design. With a actual fueled engine the rpm would be considerably higher. The power pulses of this engine would be VERY close together. Also consider that your motorcycle's wheel only turns about 3000 rpm at 200 mph so if they attain their goal of 3000 rpm on Diesel/bioDiesel a 1:1 gearing might make you guys very happy. They claim the engine could be configured to run whatever compression required for the fuel being used. Novel concept and it just might work, I understand the principle but am a bit unsure of how they transmit power with the lead/lag of the pistons without some sprag or cam arrangement. I don't think you'll be seeing this in a production vehicle any time soon.

You could also seacrh for "Quasiturbine"
for a wankel-like 4-sided instead of 3-sided
rotating engine
Is the patented design royalty claim too high
because this one has been around long enough for mass production

I hope to see photodetonation and clean burning in the future

Mighty engine

It would be nice to have a real dyno.

And see what happen after for example 24 hours of running.

The durability of the system is my main question, because like the wankel (rotary motors of Mazda) the force apply on the crankshat is oblical. The joint on each end of the arm inside the motor will be on fire and will need attention.

Otherwise it's a better idea then the explosion motor who have 100 years of improvement and who have 1 stroke at each turn who are pwer stroke the rest are lost....

The internal combustion motor we know have something like 25-28% of efficiency so anything could be better.

A follow up of this mighty engine will be interesting.

how much energy is available per gallon of gas?

i'm tossing the BS flag....

30% efficiency, my little 600cc bike runs 50 mpg. We'd need 90% efficiency to get the fuel economy to 150mpg....

the problem with efficiency is the combustion cycle. You lose heat (energy) with every exhaust event. You lose heat to the metal parts and cooling system. You lose heat in the bearings and such. there are all kinds of losses that just don't disappear with the rotary style layout.
