@richmondred01 @Greentored @Achto @Ed Kennell @The Tuul Crib and other engine builders.... what day you?  Piston return springs?

 

The video is Russian, voiced over and a bit odd... but it’s what popped up.  They claim to add 7.5 hp per cylinder on a small car.  I wonder what it could do for a Kohler?  My first thought... is what about valve clearance?

 

 

[DennisThornton 4,769]

Busted piston tops, bent valves and broken connecting rods if it managed to even crank over.

 

You'd have to REALLY shorten the connecting rods, which would rob lots of HP and then spring steel is tempered at a low temp, WAY, below what would be in the cylinder.  When they lose temper they aren't springs anymore.  Whatever pressure they would add on the downstroke they would steal in the up stroke.

 

All nonsense to me.

It is.

 

It's an internet joke.  Been around a while now.

I like the daily driver in the background on the rack, burnt look paint, chain link steering wheel!

 

Valve what valves, might help hold them closed! 

 

Figure those springs would wear a hole in piston in short order.

If you put another set of springs underneath the pistons, once you spin the engine over you could have perpetual motion. When the springs on top have pushed the pistons down, the springs underneath will push them back up and so on and so forth 🤔. Doesn’t time fly, is it April 1st already?😂🤣🤓

don't you get the maintenance free ones installed at the dealer?

 

This close but might be true!

Having managed a hydraulic laboratory where my goal was to extract every  0.001% of HP out of each gallon of water that passed thru our hydro turbines, I can tell you there are no free rides.

I have sat thru several presentations where perpetual motion devices were being promoted and they all failed after close examination.   All machines ,mechanical, hydraulic, and pneumatic have losses. This includes springs.   Some machines are very efficient, but there are no 101% efficient machines.   The best hydro turbine I ever tested was Grand Coulee at 94%.

I believe next to the blinker-fluid.

I had a boss once that was infatuated with those things. He took an hour one time and drew on the white board a machine that uses Mercury and magnets to induce perpetual motion. 

I told him keep working on it......I got S%&T to do! 

Yep age old adage, "can't get out what you don't put in!"

Opposite the long weights and the P.M Tension Springs. Now that’s a thought, if you fitted tension springs in the crankcase you would avoid the effects of high temperature on the springs 🤓😉hee hee.

[Achto 27,622]

If, IF you designed an engine to use those it is true the energy used to compress the springs would out weight the energy gained by them. The only benefit that may be gained is a lower possibility of breaking a rod. A rod will normally break on the exhaust stroke because you are relying souly on the strength of the rod to change the direction of the piston from being thrown up to returning back down. A spring may dampen this change of direction.

 

All in all, I think you would have better luck by getting your "flux capacitor" chromed. Chrome always increases horse power.

I think you’re confusing “horsepower” with “pulling power”, I always thought  the more chrome you had, the more “pull” you had, (with the ladies!)  👩‍🦳👩🏻‍🦰👵

I found those do-dahs on the aisle after the grinder sparks and pop rivet holes.

Ed, In your lab work, did you ever test cross-flow turbines?   Many years ago I was given the task of setting up cross-flow turbines on a dynamometer...   They were much more efficient than the old water wheels they were designed to replace.  Danny

And I'll be gobbed struck if I can find a sky hook or a bucket of blue steam at my local hardware store.

The only thing I can think of that was anything like this, was an ignition system way back in ye olde days.

Piston-trip ignitors. The piston itself had a cast boss which would make contact with a movable set of points, when they collided, the points broke open and fired the mixture. Some number of engines used it in the early 1900's. Edwards was one to be noted..

A piston-trip ignition two cylinder engine, which boasted 'excess efficiency'.. You could simply cut fuel to one cylinder..

Still dragging it through every cycle.. Rated 5hp or 1.25.. two or one hole firing respectively. 
Made for quite a show when they broke.. 

Anybody seen one of those 'fan-wheel spark plugs'? These too boasted more power and better performance..

We had no idea you were that smart Ed  

 

Just bust'n! Had a couple Mai Tais so ....

Curious about that Grand Coulee and what you think made it so efficient. 94% is pretty good!

Be careful of the recent Chinese imports!  No comparison to our domestic exhaust bearings!

I’ve always found that “Grinder Sparks, Pop Rivet Holes” & “Long Waits” are pretty consistent quality wherever their from. “P.M.T.” Springs on the other hand can be quite unpredictable depending on their nationality and phase of the moon 🌙⚡️💥

A large project was required to justify the cost involved in the design, manufacture, and testing of a model turbine.    

 The models I tested produced around 300HP. The prototype turbines built based on the model test produced much more, for examplee  the  Grand Coulee turbines produce one million HP.   The cross-flow turbine was designed to be a small inexpensive means of generating electricity in remote areas with a very low head dam.    They were a reaction type impeller designed for low head / high flow conditions.    I have tested Pelton, Francis, fixed blade, adjustable blade Kaplan,  and reversible pump turbines, but never a cross flow.

Many things involved John.    The relatively small head range 1210-1290' allowed us to really tweak on that range.   The fairly high tail race elevation helped negate the concerns with cavitation pitting.

At that point in time there were no requirements for minimizing fish damage  or aeration of the downstream water.     I had many turbines in the 92-93% range.

BTW,  the Grand Coulee model produced around 300HP in the test stand.    The prototype is producing just under 1,000,000 HP.
