New turbo transfers power direct to the crank

[jim whitmer]

I have finished the design work on a turbo that I invented several years ago. The patent is now pending. The turbo has four pick up blades, one located very near each exhaust port of a four cylinder inline engine. A common shaft joins the four pick up blades and at one end is a compressor blade which blows air into the engine just like a normal turbo. At the other end of the shaft is a very small gear reduction box which drives a small slipage converter which drives a ring gear that is connected to the rear of the crankshaft. Once the desired amount air boost is aquired from the front of the turbo, instead of a waste gate the unit transfers the remaining energy to the rear of the unit where the gear box picks up the energy. If you want additional info call anytime 405 751 4521. Please be polite. I am not interested in arguements. Combine this with my Alternating valve engine and mileage will go the the moon.

This is very old news.

I think you will find the efficiency gain requires the engine to be operated at a very high rpm because the turbine requires a high volume of exhaust gas to provide any benefit. Note the two-stroke diesel engines and the necessarily high rpm aircraft engines mentioned in the Wikipedia article. Unfortunately, this is the realm of horsepower and is far above the realm of torque, where mpg gains are made.

I hate to break it to you but turbo-compounding was invented many, many years ago.

Well, OK, I don't hate breaking it to you.

As above, bitof an old idea which has been sidelined for sometime IIRC it was because the net gain wasn't great enough compared to a regular turbo on smaller engines, there is a lot of work (@crank and compression) from not-a-lot of work out (exhaust)

I wonder what the motivation is? Do people send him money or what?

"Once the desired amount air boost is aquired from the front of the turbo, instead of a waste gate the unit transfers the remaining energy to the rear of the unit where the gear box picks up the energy."

Should read:

Once the desired amount of cash is aquired [sic] from the rubes, instead of a workable product the unit transfers the remaining money to the rear of the shop where my brother-in-law, Buba, picks up the cash.

Ptero - In theory, couldn't you spin a smaller engine faster to get the same HP out of a similar amount of fuel?

...the R3350 engines on our Lockheed EC-121 "Warning Star" airborne radar station were "turbo-compound" where three power-recovery turbines (PRT) "collected" exhaust energy and coupled it directly back to the main crankshaft.

...good for an additional 150 hp from 3,000 hp engine...and really helped reduce their fuel consumption numbers at cruise.
