Well, such questions arose, so I answer ..
Questions.
1. Why is an electric transmission from your crazy oscillating engine, an associated generator and the electric traction motors more efficient for a steam locomotive than direct mechanical traditional dual acting steam pistons or a steam turbine?
2. Why is the on board steam generation with whatever fuel is being burned to heat the water in the boiler more efficient than a large scale power station and transmission via catenary or third rail?
3. What fuel does your locomotive use?
4. Why not use your engine to power the wheels directly?
5. Did you know that steam turbine-electric locomotives have been tried before?


Ad.1. Here you are right that you call it crazy oscillating ... Because as you can see the madness comes from it, it is 20 times lighter than a traditional engine, for the same displacement .. And it results from mathematics and is indisputable .. Or maybe even be 50 times lighter, because thanks to the reduced weight, we can get much more revolutions and thus obtain more power, but if we still need the same power as the traditional one, we can reduce the stroke volume, and the engine will be lighter than 50 times .. And that's how you well-called the crazy property .. Here are some drawings to help you understand it. And the fact that the "cylinder" is lifetime, this also matters and can only be machined with an accuracy of 0.5 mm. The "piston" does not rub against the cylinder, and the method of transferring the operating gas force is much more efficient, because there is no traditional cross-section where some 20% of energy is lost.

It is a pity that Newcomen did not come up with this solution for a long time, but it was very close .. :lol:

Here's a story, like this idea, of it
engine was established.

Ad 2. Because simply by transmitting electricity to further distances, we have 30% losses on network resistance and transformers .. When you add the costs of building and maintaining such a network, we can add 20% ... so we have 50% savings ..

Ad 3. Any, such as we have at hand and is the cheapest for us .. From wood, through coal, oil, gas ..

Ad 4. I have previously published such solutions .. You can choose what seems more beneficial to us..

Ad 5 . Yes, but they did not catch on, the steam turbine has its drawbacks to such a solution .. especially it is not so efficient at low revs .., it cannot be used for driving backwards, etc.

Now here's a good one for Andrew, even with his complex advanced jaw dropping design department which a lot of us mere mortals out here are in awe of and struggle to understand.
The challenge for 2021?
How to fit a set of wheelbearings into a Marine Engine without really trying.
Parellel, taper, ball or roller, twin or single track, thrust or complete with integrated spring loaded seal.
Right hand, left hand and ambidextrous applicable applications welcome.

Well, now, since we do not really believe in the old rules of the heat engine * because as it turns out, the "cold engine" also exists, I will try to explain why such unique advantages of my new 4 stroke come from ..
Well, in a traditional engine, the speed of fuel combustion reaches a speed of about 30 m / sec. mIt is not that much and the duration of this combustion causes a heat transfer to the walls of the cylinder, the piston bottom and valves ... because it's time ... I in my engine, by accident (I could not get the ignition spark, because the speed was too high in " chamber "caused that the air ionization, which is necessary for the formation of the ignition spark, could not take place, because it was blown away by a large mechanically forced speed between the electrodes of the spark plug. I even got one blue smoke that would testify to burning .. If not for my first prototype, which ignited perfectly in the first revolutions, I would probably give up further work on this engine .. 1 4 days is a really long period of testing .. But I started to have fun , search the biblotehs about the mechanism of spark formation, and I found the reason .. Transfer I used the speed that could have been in the channel where the spark plug was contacting, and it turned out that even at relatively low revs that are needed to start, the speed in the spark plug channel was around 300 meters / sec, i.e. Mach 1.
If, instead of the spark plug, there was a diesel injector, the engine would probably ignite immediately and its speed as a diesel engine could be as high as around 10,000 rpm. because the speed of 300 mtr / sec is 10 times higher than the combustion speed in a normal engine .. But I had a gasoline version, I had to disassemble the engine and dig this channel in the head, and maybe the speed in it was as high as 100 m / sec, which allowed ignition spark and normal engine work .. But still 100 m / sec and 30 m / sec, it is 3 times higher combustion speed, due to these mechanical forces .. And this 3 times higher combustion speed in real terms, it can actually affect the thermal efficiency engine, and much more than you might expect .. Therefore, the current considerations on the thermodynamics of the engine are largely outdated in relation to my new4stroke .. which additionally has a unique small combustion chamber below the smallest piston .. where practically only combustion takes place in a vortex of enormous velocity forced by its small cylinder

, additionally. here are two videos, one about the experiment of flame spreading in a pipe filled with a stoichiometric mixture with fuel,

and the other about the flame's front face, which we can easily see. If the flame was moving 10 times faster, as is possible for me, it would not be so easy to observe ...

That's it for this Christmas this year ..
