Two-slider crank mechanism 9

To create faster and more economical internal combustion engines, I propose to use my invention - Riyanov double-slider crank mechanism (Two-slider crank mechanism). I received 4 patents in Russia (№ 2634851), China (№ 3349271), Japan (№ 6373516) and the UK (№ 3530879) for my invention, which can be used to create more environmentally friendly and faster engines, generators or in other projects.

SUBSTANCE: crank double-slider mechanism includes a crank, two connecting rods and two sliders. The second connecting rod is connected to the first slider at one end, and to the second slider at the other end. The second connecting rod length is equal to the sum of the double crank length and the distance between the connection point of the second connecting rod with the first slider in the initial phase of its movement measured in the direction of the first slider travel and the longitudinal axis of the second slider.
EFFECT: ensured full turn of the crank in one stroke of the extreme slider in the chain in one direction.

The unconditional effect of the two-slider crank mechanism is overcoming the limitation in the number of revolutions per minute in the internal combustion engine for the same working stroke of the slider, which can be used in internal combustion engines requiring high speed (for example, drones (land, air, water), subcompact cars, motorcycles), as well as in electric generators based on internal combustion engines, wave electric generators.

The key predicted effects are a gain in speed, a reduction in fuel consumption, the use of fuel with a lower octane number as a result of an increase in the working stroke of the slider, simplicity of design (gears are not used to double the speed).

I propose to use internal combustion engines based on the proposed mechanism primarily in unmanned aerial vehicles.

The subject of discussion is the possibility of practical application of the proposed mechanism in internal combustion engines.

In existing internal combustion engines, the crankshaft makes half a revolution per stroke of the slider in one direction. In the proposed mechanism, it makes a full revolution per stroke of the outermost slider in the chain in one direction.

One of the expected effects of the proposed mechanism is fuel economy, since less fuel is required to ensure the same speed.

Re-read posts 55 and 59, and explain with sound thermodynamic reasoning and P-V diagrams why this should be the case. I maintain that it will not. The combustion chamber doesn't care about the design of the mechanism that turns up-and-down into round-and-round aside from its mechanical efficiency, and a normal piston and connecting rod has a lot fewer moving bits and pieces than this one ... and no potential binding.

Thank you for your comment, according to the law of conservation of energy, the speed increases, but the torque decreases. When compared with a conventional crank-slider mechanism, the outermost slider in the chain ensures a full turn of the crank in one stroke, so the speed increases twofold. If you mean the additional energy consumption to overcome friction, the design features of the mechanism, then the answer can only be given after computer modeling at least.
I have already noted earlier that I have provided all the information I could provide. I have nothing more to say on this topic.
All the best to you.

Let us know how all the engine companies react to the proposal package you have put together and sent them.

If you provide a list of the companies you are working with, that would also be interesting.

Speaking of thermodynamics, where is the lost energy going? Are the connecting rods getting hot?

Thermodynamic processes are the same as in a conventional crank-slider mechanism. But due to the fact that the number of revolutions per stroke of the outermost slider in the chain is doubled, it is theoretically possible to save fuel or use less flammable fuel, which reduces the heating of the mechanism's structural elements.

Fail.

That is all.

I give up.
