The issue very much often raised, important for aviation :
Yeah I just wanted to clarify this matter of the weight "be greater" for my solution.
She is very often raised, as the lack of the advantage of my engine.
And it is of course the untrue, but intellectual ‘box’ are ordering to think so, that it is a truth.
As a token of it I did taking off the weight on which I put the valve with the spring and spring retainer(witout retainer locks) diametef full phi 32 mm ( diameter canal 30 mm),
And I other side Piston , rod, pin,and two rings diameter 38 mm , what is a greater dimension than a valve has him considerably.
In spite of it, in the photograph done by me clearly one can see, that much he is heavier unite the valve.
If not you believe, go to scrap, find and take the piston with the connecting rod from the old lawnmower and about the same diameter valve with the spring from some car engine.. I think that you will be not having to use scales, because after taken into one hand piston, and into second of valve, you will be sure knew what was heavier.

If now will add to the moving weight of valve ( the reciprocating mass) rocker arm, mecanical regulations of clearance valve (or very heavy hydraulic valve lifter( tappet)) taped (ewentualy push rod). it sure it will turn out that the weight of the valve is twice as bigger from set piston –rod same diameter.

However, that's not all in relation to the weight.
He is reaching to valves static weight so things like valve quide in heads, and rocker arm shaft.
One should also add the weight not chosen materials of the head, about the diameter piston. and lengths of his cylinder.
For lowering static mass of the engine one should add the lack bolts for screwing the head, since altogether cylinders around wit cylinder valves it is possible easily to make one-piece steel out, and then aren't needed bolts to the head together with threaded with their nests.
Adding this static reducing the weight, we receive altogether the piston valve is three times lighter than the traditional valve.!!

And greatest loss of engine mass.Piston valves mass, at the same diameter like valves, they cause that he is arriving about 15 % of jumping volume of the engine. That is mass of the engine is also reducing about 15 %.

In net part all about termal efficiency.I am only attention, so most important in combustion chamber, are TEMPERATURE elements.

All detail about photo:

Poped Valve : weight only poped,springs,taper all 176,5 Gram.
Diameter 32 mm
diameter open gap 28,5 mm.

Piston with rods, pin, two rings , weight 160,5 Gram
Diameter 38 mm - it's 25% more poped in diameter( some weight are they grow with the square of the radius) . Gap 38 mm .

Such a difference, that for the stability, one should add the biggest weight from the set to this scale

Hello Feliks,

I believed you prefer rotary pistons and valves with a special mounting of pistons and rods :P

YEs Remundo , you right :D



And now small warning for future designers of my idea engine. What problems clearly apparently they will have to deal with. It is an effect of ten-times increasing the power in relation to the mass-produced fiat.126 engine. During this attempt turnovers didn't exceed 3500 RPM one can see , but effects

Image

Shows it has become with polished rod on photo .It color has been changed on result of temperature on bearing on blue .Of course, at present everything is exchanged and the engine is sending for the demonstration of his work.

Yes, at the animated film he doesn't have the outlet pipe and intake. In every traditional engine such pipes are and it is about dimensions very much determined which they have very much a large impact to ultimate parameters of engines. In this structure of the phenomenon occurring wtych pipes are much more intense than in traditional engines, because of opening and shutting a ports are during max speeds of pistons. At such violent opening, phenomena resonase are very strong. One should in detail work them out.. I applied such phenomena in my engine, having some given from one men worked Peenemunde under Werner Von Braun :)
Walter Kaaden - Wikipedia, the free encyclopedia

Kadenacky was a forerunner .
Expansion chamber - Wikipedia, the free encyclopedia

Kadenacy effect - Wikipedia, the free encyclopedia

I designed at first time my prototype of engine 600 cm^ 3, to parameters 100 HP. And there is only a wonderful trick here: the Engine surprised me favourably, and has 2,5 times of more power than I established .... :) Neat trick !!! :)

Hi Andrew,

You prefer to get some additional power from your exhaust rather than make a lot of noise...

Hum, I think you're right :idea: like many other french inventors like Kadenacy :D

Bye :P

In 1981 we dont have internet....

Some work with "resonace"

Amazing pipes, Feliks :P

What a resonance with 2 on each side of a motocycles !

Ok,
And now about the most important advantage of my engine
This structure how, higher I demonstrated the graph, has the different degree of compress ratio on placing angles between two crankshafts .
The changeable compression ratio was applied in a few advanced different structures of special engines .
He has most often been carried out with the help special Biceri pistons.
Image

and these are virtues from using it

Image

Image

Thorough description in the NASA contango :

http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19800011788_1980011788.pdf
In my structure exceptionally it is easy to carry out such a changeable compression ratio. He is carrying out sie it behind the help very of straightforward device for the picture. And most important: this device is changing the compression ratio in all top hats of the given engine(even for example 16 cylinders).
It is very much cheap way, and simultaneous in the reliable way is carrying out all described higher virtues of the changeable compression ratio.

Image

Engine new 4 stroke has changeable compressio ratio.
It's up to the angle of coupling with the main piston .

Graph some varations:

Higher I described a few fasts way to the autoload of the mobile phone behind the help of the watch mechanism to alone of winding, which driving the electric generator will load the phone call automatically at moves of the phone.
Now I am still presenting one way of solving such a mechanism.
Image

Image


At putting in the mobile phone let us say six of such mechanisms, it should be enough to holding the phone in the readiness to work and the stand-by.
But for all certainty that we will always be they could use the phone, even when long he was in the stillness he proposes to add the handmade knob for winding such a mobile phone up, similarly he is like it in watches with such a mechanism. Then we will already always be sure that we will be able to use our phone, because of it we will wind lichen by hand, and then really we will get the full independence from the electric current and the traditional battery charger.

Image

At the amount of mobile phones 1000 000 000 which everyone is downloading from let's say 1 Watt, we will save it of current in the height of 1000 MW.

Regards Andrew :D

Particularly how you will go to the long fell-walking and you will get lost
