The Dr. Paul Internal Combustion Engine - 80% Efficient!!!

[leotron4]

The point is that combustion engines are produced by car manufacurers, and this is what they do, 10% efficient engines, because that means more profits for them. we cant develop this technology its so expensive. So, fight for it, OR produce your own engines, like this very good one on compressed air: watch?v=k7e_4Fs-C4I

Interesting video, especially the beginning where the folly of ethanol is explained. Every congressman should see this. I find the 80% claim hard to believe because a lot of energy goes into heat, but even if it's 50% there will be a lot of interest from investors. Assuming they've got it all working, the biggest hurdle they'll have producing this in the US is meeting the CAFE standards.

I am an engineer very interested in motor design. This might make an interesting 2 stroke motor, otherwise i am interested to see your valve configuration especially considering the compression ratio of 30-1, I am certain it will never be 80% efficient. Way more than 20% of the heat will be absorbed by the metals in the engine. Not to mention all the gearing losses from 4 crankshafts. Perhaps with ceramics it might make 40 percent efficient. However ceramics aren't very economical yet.

Ah, I see why he uses 4 cranks; elimination of side loads - nice idea, but heavy and expensive.

[ptairco]

This really isn't anything new. It is a piston ported, opposed piston engine. These have been around since the 1920's. Fairbanks-Morse, Junkers etc built them quite successfully and they were used by the 1000s. His use of 4 cranks is different (but why?? Balance?), other than that it essentially the same principle as those old engines. Which were great by the way, and have a lot of features to commend them, not least is the elimination of all that complex valve gear and cylinder heads.

This is revolutionary technology, but I doubt 80% efficiency.

[drpax]

I'm skeptical. Metals undergo creep at %40 of their melting temperature, which is 212F for aluminum. Burning fuel that hot would melt the engine! And even if they cooled it thats still heat lost resulting in inefficiency. I think he lies.

[mechanicalguy]

This is absolutely excellent.

I feel so enlightened. I'm very interested in this technology.

I've always wondered what that radius was at the bottom of cola bottles...I thought it was purely aesthetic. Let's get products like this in production asap.

[quasarhi]

Are there any working engines yet ?!

The world needs solutions now !

[dxbender]

From what I understand, a working version exists, but details are classified. The prototype shown in the video is the non-classified version and was used for extensive testing from which the numbers originated. The main thing missing at the moment is funding to take it to the next step...

[WolYou]

Fuels going in the atmosphere? Probably. But the main problem with efficiency is not the burning of the fuel (there is lots of good tec to overcome this i.e. piezo-rails used in diesel motors invented by AVL in Austria) its simply losses due to temperature and friction waste. We are cooling the combustion motors in order to waste the energy wasted by the motor beforehand. Using energy better means nothing else than using the temperature better. People can only think in piston and combustion.

I can't seem to find anything on this company on the internet. Can anyone help?

Thanks

Hey there...this engine is being developed by the Engine Corporation of America, by Dr Marius Ana Paul...there is very little information on their website, but I assure this is very real technology...just meeting a lot of resistance from the established industry for very obvious reasons...
