Can a Rotary Engine Efficiently Charge Batteries in Hybrid Vehicles?

[camerart]

Hi,
Have you ever tried to invent anything?
Long ago, as a school boy after learning about internal combusion engines, I 'invented' a rotary engine. (It had actually been invented in the 19th century) My dad said "If Fords can't do then you can't" So I stopped. Years later I learned about the Wankel engine, which was similar to what I had thought, and carried on trying. I didn't mention it to my dad again.

I went through lots of iterations, and tried to get any interest, but gave up some time ago, and put it out of my mind.
The last iteration, was for an IC engine battery charger for hybrid vehicles, which didn't drive the wheels, had no flywheel and could infinitely change the compression ratio.

Here is the idea (animation), which I stress is not in anyway a drawing, but just to illustrate how it would work. I hope you find it interesting.

KEY: Light blue incoming gas--dark blue compressed gas--red combustion--brown exhaust.
Cheers, Camerart.

That is basically a 2-cylinder 2-stroke engine with the crankcase replaced by your "head pistons".

You may need some valves, either on the intake or exhaust side of your "main pistons" to regulate the flow (similar to a supercharged 2-stroke as presented below).

I think you would find the Napier Deltic interesting.


It's kind of obsolete, but still: historical.

I think you misunderstand the mission of PF. We are here to discuss mainstream science and engineering as defined by textbooks and peer reviewed papers. We attempt to help members to understand. This is not the place to discuss new ideas or new inventions.

Member @phinds said it best.

Thinking outside the box only works well when you first understand what's IN the box.

Think of PF is the place to come to learn what is IN the box. Thinks like existing rotary engines.

If you look a little closer you will see that this design has variable compression ratio, also there are valves on the intakes.

Hi R,
I studied all kinds of engine, including the Deltic, which I remember being tested on the railway near me.
It has crankshafts plus lots of moving parts, where mine doesn't, which would make it obsolete.

Hi A,
This isn't a new invention, it's from my past, that I thought may be interesting, I hope I didn't offend you.
