To understand the phenomenon of inertia one must do simulations on computer and see how a motor behaves by watching it work with slowed images.
Yes OK but these simulations start from a mechanical principle. This is what I would like to understand: what mechanical principle makes the inertia of an engine the biggest problem? A tractor engine has a big inertia but remains the best engine usable for agricultural work. My diesel engine has more inertia than other engines but is still very usable (especially given the low speeds generated).
Which simulator do you use?

Inertia disrupts movement, making it irregular. In my case, it is the inertia of the pistons that disturbs me. I use CosmosMotion, it's also called MSC Adams. Besides, I bounced a little on what Christophe said somewhere; Inertia is not a reserve of energy, it is energy wasted.
To start a motor, we use electric energy, this energy comes from the battery, which itself comes from the alternator, and to have it, it was necessary to overcome the force of Laplace, the one that opposes the current that gave him birth.
So when the engine stops, this energy is lost. The few turns the engine makes after shutting down the system are not enough to recharge the battery. It was necessary to spend energy through the alternator to be able to recharge the battery

I understood a lot by doing this and in any case, a parts like a rotating (heavy) crankshaft that is not perfectly balanced is a great big problem.
OK but between the dynamic balance of a rotating part and its inertia is not the same thing. A room can have a huge inertia (a car wheel for example) and stay perfectly balanced.

Yes but precisely, a crankshaft is not a wheel.

In addition it is hyperstatic when multiplying the number of pistons.
????? Hyperstatism is when the same degrees of freedom are blocked several times. What degrees of freedom "desirable" to the proper operation of the engine can one block by multiplying the cylinders and pistons?

There is a formula in mechanics to check the proper isostatism of a mechanism.
If one becomes hyperstatic, one contracts the matter and one loses power, if one is hypostatic, the mechanism breaks the figure.
Being isostatic means being subject to balance.


And then anyway, it's not and it will never with a classic crankshaft that the engines will be powerful.
For the moment, the experiments that I have seen are essentially focused on this type of engine. The other methods are sometimes even theoretical (I think of engines without connecting rod for example).

This is where it becomes wise to adopt a radically different architecture.

What makes the power of an engine is the distance between the crankshaft and the connecting rod, and the greater the distance, the greater the output torque. The lever arm increases the force.
Yes but it also means a low rotational speed with possibilities of filling the cylinders not always optimum (speed of the gases). The same principle is found in cycling where, theoretically, the longer the cranks are, the greater the force to the rear wheel is. The condition is that the legs can be turned very quickly and the muscles do not develop at The infinite!

That's true, but look at the pictures of Inventor, I prefer a motor with bcp torque that runs smoothly, it will last longer.

Cylinder head, i'd say

And lastly wear on the lights, low engine life, like the 2T.

Hello
At power, torque and equal displacement the 2 times are more reliable than the four-stroke, whether on 50000cv slow-revving engines or 280cv / liter racing multis.
Must forget the legends and dkw

PS: 2T does not necessarily mean light

A rotating mass (vibrequin for example) stores energy, you can feel it by braking it with your hand.
The inertia of the pistons, on the other hand, is lost, since the direction of movement is inversed all the time

I wonder what use it is for me to answer with technical explanations ... Have you read what I have written at least?
You do not spend energy to put your crankshaft in motion at the start? She falls from the sky this energy ...
And what about your reserve when the engine stops?
You lose everything, so you do not stock.

ah? Well, I was still there.
what did they do instead?

I had read, if so. you lose 1 but you win 100000000:
At each vibrator's turn, this inertia will move your piston to make the escape, intake, and compression. If you want to do without it you need a multi-cylinder. On the other hand, it will regulate the rotation, help your engine to turn round.

You reason as if the engine is running constantly and never stop.
As if you never spent energy.

Yes. I dissociate the start of normal operation. one is a short phenomenon, which represents only a very small part of the time of use of the engine and during which the engine does not operate normally and without being in charge. The other consists of a cycle repeated ad nauseam, under the actual conditions of work.
