Intake Valve and Feliks' ideas

All that has to do with the power train, gearbox, clutch, fuels and lubricants, etc. Generally the mechanical side of Formula One.

The beginning of this topic talks about intake valve etc, i just saw this video on youtube yesterday, i find it amazing it shows what happens inside the piston of a 4-stroke engine while running, actually taken from a real working engine. amazing really.

ernos5,

There are lots of things obvious in that video.

1) If the color is good, the engine is running rich because the bulk of the flame front is yellow instead of blue.

2) The engine load is low, or the ignition timing is retarded, because the spark occurs at what appears to be about 10deg BTDC at most.

3) The fuel delivery system (carb. or injection?) is not very well developed, as you can see liquid fuel dribbling off of the intake valve during the latter portion of the intake cycle.

4) The HC exhaust emissions must be sky-high, as illustrated by the over-rich,late-cycle flames present around the intake valve margin. Or maybe the intake valve seat is bad?

Wouldn't pass a smog test.

At this film very well one can see, that the sucking valve is standing on the road suck blends. and it is a big obstacle, since at times we can deal with speeds sound at sucking in.

Some advantages "cylinder/piston"design:
1.
Significant smallest mass a lot turning, but that goes behind it, masses of inertia are small for such such array. For example, for one kit one ( four cylinder ) only rod.
Due to capability behind assistance of joint in pivot of crush many cylinder, for 16 even " cylinder ", one remains further only rod.
Image

Mass is put in majority also near pivot of turn " crush " very, that causes that power of inertia are relatively small .

Theoretical exemplar it on inertie :Image
Largeness depends on pivot in square on distance . But main mass is concentrated this "piston" pivot of turn near , rally will be relatively small inertia.


In amount, waste of mass so significant reflexive , for the same jumping capacity of conventional engine and my, boost of physical efficiency causes, but that goes for decrease of expenditure of fuel it.
Facility of cooling of crush also, through feeding of water by pivot of turn of crush, and then, excellent cooling , it makes it possible boost of degree of compressing ( proficiency ), but, at low emission NOx.
All these above-mentioned advantages, they cause that this solution has better physical proficiency has significantly, than conventional .



2.
Considerable advantage of such solution, easiest technology of execution is about many "piston/cylinder ". Cylinder, it does not need exact processing very, as nothing slides after it, it can be executed as extracted from aluminum profile , in ready for service version .Accuracy of execution is in this case completely enough. Inaccidentally of aluminum cast, there would be ready without no engine processing for use it .
However, it requires "piston" on generall purpose machines polishing only.
This technology is cheapest about many, than hitherto existing, it required which (proceeding ,polishing) machine.General repair of engine relies on exchange also only seals, "piton" and ball bearings, without taking out crakcase .

3.
And most important advantage
All can be closed in this engine type ball bearings.It signifies with solid lubrication in means. (the same type as in wheel of cars ball bearings). So, all can work without traditional oil. Possibly, crunching requires oiling crush of /cylinder only. But it to very minimal amount, because crunching only just.
If we will employ array on piston e.g. Teflon- (surface of piston only) stainless steel,
ceramic - stainless steel, or ceramic -ceramic(lubrication water),or similar arrays, it will work without oil engine completely oiling.For diesels, I think, that it will enough oiling diesel fuel .

Image
Thus, whole crank case, it can be opened completely and there to be cooled swimming air.

4.
Due to outsized margin of "piston in cylinder", any kind of deforming thermal or mechanical, will not have critical meanings as conventional engines so .

This my solution has such advantages in generality " cylinder/piston "

Feliks,

Since you keep posting your ideas for IC engines, I can only assume that you seek some constructive criticism, right?

A couple comments regarding your "bowtie" piston engine:

1) The single con rod reacting all of the combustion and inertia forces in the system looks far too small for the piston area.

2) With all of the oscillating pistons in phase, your proposed engine configuration (as shown) would have a reversing primary force imbalance about the piston axis of rotation.

3) The universal (Cardan) joints would likely fail very rapidly when subjected to high frequency, high amplitude, reversing torsional loads.

4) With the large surface area of those "bowtie" pistons exposed to hot combustion gas, the heat load into them would be substantial. Is there any means for getting that heat transferred out of the piston structure (besides the seal rings)?

Regardless, I do enjoy your posts. Keep it up!

Opposite too RB211 engine:

60 „cylinder” star half rotate engine parameters:
Diesel engine, sum 250-liter work volume, 4000 RPM,

20 000 KW, 170 g/KWh.--- 5,8 KW/ KG, full power: 3,5 Ton /h

250 L / 15 =16 liter work /4 cylinder x 2 = ~~ 32 liter full cylinder volume dimmer

long cylinder about 300 mm .(3 dcm), 32 / 3 = 10,5 dcm^2 S cylinder

10,5 / 3, 14 = 3,34 (r^2) r = sqrt 3,34 =1,8 dcm (180 mm) d cylinder = 360 mm

Sum D = 900 mm , long =1200 mm, d cylinder = 360 mm
V all engine = 4,5 x 4,5 =20,25 x 3,14 =53,5 (S dcm) x 12 =642 dcm^3

All weight (aluminum) 642 liter –250 liter =392 liter x 3,5 KG =1372 KG ( 1,37 Ton max weight) ~ ~ ~ ~ 2 Tones weight. . And birds no afraid :)

If Andrew's English was a bit better, I think I would find that he is the only person that I have ever met that is further outside-the-box than myself!

Great stuff, keep it up, and maybe pick up "Rosetta Stone: English"? I may be willing to send it to you if you would use it and maybe have clearer vocabulary to describe what is happening?

Re: Intake Valve

In my latest solving the oscillatory dynamo, a diode who exchanged the changeable oscillatory electricity for the electricity about the permanent polarity was crucial element
Such an element fulfilling identical functions as the diode exists in the hydraulics of theses. There is a valve one-sidedly letting it in to water. it is opening for example only then when the pressure from the feeding side exceeds certain described by the threshold e.g. 10 bars. When the pressure is on the feeding side it is smaller, the valve is closing it oneself. and doesn't allow for moving back waters.

The principles of operation are the same like at pumping the bicycle wheel up with pump, but will refer to water. In this way we can hold. in the pipeline pressure e.g. 10 bars, and from leaking out of the pipeline who will be above the pump e.g. 100 meters will be sailing out water.
The one straight line I decided to use the principle for the production of the electric current with the help of sea waves. Although he is supposed to produce the electricity, it is being imported these are for inflating the problem waters sea into the container with water sea e.g. to height 100 of meters, or similar (e.g. on high cliff seashore). The rest is known and professionally made as the normal power station aqueous, but in this case she will be to sea brine. isn't buying it special one should actually solve the difference, only a matter of the precipitated corrosion .


Particularly that such a very similar solution was already on an island applied Okinawa, in the version of the power station pumped storage (but pumping into the container with the help of the electric energy- classic pumped storage).

Into my to pump the version this brine there will be sea waves driving water pumps with valves with diodes into the container Leaking in water only in direction of the container. pipes from pumps into the container will also have middle diameter, in order to in the time of whom from valves, not to waste the energy from different good pumps. Unfortunately the number can reach such pipes even 1000, at the productivity every e.g. 1 m^ 3 / sec.
But by it we can get the power of such a power station 1000 of the MW .

Costs of making such a power station will also be smaller, since for her devices won't have to pump water into the container how it is in classical power stations of this type. Machines will be so like by a normal hydroelectric power plant straight lines and no high cost.

Also shortened descriptions Polish pumped - storage to slight differences of the water levels (100 m) is describing http://www.pistonheads.com/gassing/topi ... 7463&i=260 or
http://www.new4stroke.com/plants.pdf


Gross from many centuries of coasts England and Ireland they were attacked by marine waves .
People built obstacle for these waves sometimes, that they did not prevent from life on islands.
I think that would end this immemorial war goods , and invite this ocean on coast, but that it is high, it belongs it help. It belongs to take advantage it waves, in order to they pumped on its high coast of water.
I think, so around England , Ireland , North America ,shall made this power plant.
More belongs to place in ocean for water pomp e.g.

Pistons type , or my idea half rotate, which will drive usual floats clinched for they behind assistance of rope. Ordinary belongs to place behind each pump bolts, which will be opened e.g. at 10 kG/cm2 (Acting similar for diode I my oscillating dynamo) and which for collect tubes for reservoir on high coast miss water drive it.
Collecting tube should for example for flow 1 m3/sec 0,6 m have diameter.

Image

Image
Image

For achievement in such this collecting tube of flow 1 m3/sec and 10 bar , requirement 12 pump wanted for transport water on according to following specification 100 m height too reservoir.

Pump reconciles, for simplification about normal piston, should have 0,6 m diameter, and 3 m of height. During average jump of rippling 2 m, it will give during one cycle for composite tube 0,5 m3 water pushed (S= 28 dcm2 H= 20 dcm (2 meter) = 560 dcm3 (liter). For set up flow 1 m3, TWO such pumps should pump for collecting tube.
For proper fabrication of pressure on exit of pump ( set up 10 bar ), wanted proper swimmer is.
There is simple account surface of piston of pump will together page (S) x 100 surface of swimmer.
In my example, surface of piston of pump it 28 dcm2, it signifies that swimmer)should have 2800 dcm2. In order to swimmer had such surfaces, it must have 20 m diameter, and definitely 1 m of height. It needs one kit about 12 pumps 12 swimmers 20 m each diameter, or about dimension one swimmer 12 x28 m2= 336 m2.

For behavior some reasonable spans, it is possible to accept, that for such array for production capacity 1 m3/sec 10 bar, wanted near 700 m2 place rippling sea .

Need for continuous supplying tank for power station theoretically 700 m3/s (716 MW , 100 m height ) requirement 700 x 700m2 = 490000 m2 rippling sea . It is theoretically only 700 m x 700 m !, when 2 m average heights of waves.


Here, mathematical enumeration same only:

To 1m3/ sec
1 m^3/sec 10 bar(H=100m ), 600 mm diameter pipe and piston pump, S= 28 dcm2 Hwave= 20 dcm (2 meter) = 560 dcm3 (litre) for 1 m3 need 2 piece . but period are 6 sec , sum 6x 2 = 12 piece pump .

S pump= 28 dcm2 , 10 bar, F =28 T, Hfloat >1m, S float ~~=2800 dcm2 (28 m2) , D float =~~20m
12 piece x28m2 =336 m2 ~~ =100m x 7m using area =700 m2

700 MW (700 m3/sec), H=100m
700 m2 x 700 = 350000 m2 . ~~700m x 700m area of wave



As elements are presented from marine waves over system production current professional , they are built in the world already and test, additional requirement of experience for their building not.
Another, very important information in relation to the system. System the one should be only as storage, rather than storage-pumped what significantly the height of investments will lower in comparing to current answers. Costs will only be so like for an ordinary hydroelectric power plant
Only water pumps with valves (diode) can so that touch up still and selected materials. but in general, it is piston pump known for the antiquity. Summing up, mechanical problems are solved, and with the appropriate swing one should only build such a power station.
The degree of the safety of such containers will also be very high, since put very close the sea, in case of the breakdown of unsealing, they won't cause heavy losses, since water quickly will find its way back to the sea.

I think that wonderful geographical conditions will permit on high cliff Scotland England and Ireland, to build such containers into whom sea, highest waves will be pumping brine on average in world a lot. it means that the efficiency of such a system will be most effective in world, and therefore built containers should be around these countries what in the future can guarantee the green energy for all countries Europium.

Above I described power stations to Zarnowiec about the power of 720 megawatts, and the size of her upper container

But this size of the container will suffice for the cycle 5.5 an hour long, that is through 5.5 hour we can receive 720 megawatts of the power. But if the productivity of pumped sea water is sufficient, for keeping the fluidity of the move cycle 2 hour will be enough for us an hour long.
Then about such a size we can obtain 2000 MW from the container .A by supporting the stormy weather even 4000 MW, if installed devices will let it.

On shallow water it is necessary to use half- rotate of the pump .

In of Ewas to Żarnowiec at present the employed is 114 - here with it:
three members of the management board,
29 engineering-technical employees,
59 paid housemen hourly,
9 economic employees,
10 administrative attendants.

In normal piston pump, we have two elements definition pumps – diameter of piston and stroke piston In half rotate pump we have too same elements: diameter “piston” and long “piston” and additional important possible regulations TORQUE of drive pump on arm with some hole... This same on crankshaft side
This regulation are without additional gear .


Some adwantages:
Image

For salt water I think better solution made all this pump PCW , or ABS, or propose - ceramic

Or to exchange these holes for the smoothly regulated shoulder e.g. with stepping motor driving the thread.....

It is the simplest manner of the fluid adjustment of the productivity of the pump .

Really the new system could replace the traditional injection pomp (pistons) of Diesel of the type Bosch???

Whether American landscape views will appear on Nord Atlantic? Every so water sphere about the capacity of 2000 m 3, and the height 100 m can give power 10 MW for 3 minutes. If filling pumps water with the one I believe loss is managing to fill waters up, we will have it 10 MW driven with sea waves of the electric power.
Building 100 such pieces believe power 1000 of the MW will give it to us it is so much, how many two small atomic power stations. But obvisious it will be green energy. So far windmills only had so for faith, and perhaps now will be finished with the Sphere?

Re: Intake Valve

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.

Yes. There is basic advantage, my invention by which begin developing.

All detail about photo:

Poped Valve : weight only poped,springs,taper all 176,5 Gram.
Diameter 32 mm
diameter open canal 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) . Canal 38 mm .

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