As I understand, the expansion stroke provides power for compression and power generation. Say, if the air-fuel mixture is rich (or lean) and produces more power than expected, if the generator does not extract enough kinetic energy out of the piston, would it not smack the piston to the head on the other side?
ah yes, I considered a linear generator but I was sort of put off a bit by the issue of 4 stroke balancing. but it works well for 2 stroke. 2 stroke is a bit crude but able to pull off some great efficiency number anyway. this might well work. would be nice to avoid piston friction entirely with some very light roller bearings perhaps.
will also need to keep the neodym cool. I think this could be great for range extenders
it is 1 piston? only? you can create with 6-8 ... no limits... do you have a Drawing showing us how it is built? because i did not understand how it's not connected to anything
Thanks jasbcor but it's a 2 piston engine, one on each end. You can see the 2 exhausts joined into 1 muffler and the fuel injector feeds both cylinders, the tubes in front.
Cool idea, (but not new), eliminates the power robbing crankshaft, 2 loose con rods, complex crankcase/oil pump, oil gallerys balance weights, bearings, oil seals etc.
It works just like a mag/lev train but in reverse, makes the electricity in a linear fashion, instead of powering a train with miles of electromagnets.
2 pistons, 1 cylinder, oscillates back and forth, that pretty much sums it up. The idea might not be new but there are some technical difficulties in getting it to run reliably so if they can solve those problems they might have a very efficient fuel powered generator.
It's not my inspiration, this is the work of a company in Europe. This is exactly a free piston engine with coils around the cylinder specifically to generate electricity.
Yes, this type of motor would be for a serial type hybrid car of which there are none on the market that I know of. It's a loud motor but sound dampers could solve that problem.
It will never happen shakes too much good idea though

and what do you mean by Free Piston?

The piston is not connected to anything. It simply goes back and forth to generate electricity.

yes, 1 piston. I don't have a drawing. I did not build it, I only posted the video. It's designed to only generate electricity very efficiently.

It would be perfectly suited for a hydraulic pump. In my opinion hydraulic hybrids are more promising than electric ones.

very much like the free piston engines with the magnetized piston and coils around the cylinder, did you get inspiration from that?

Ha, i knew it was similar. This type engine is also perfect for an HCCI setup

do you think this kind of engines would be good for race cars?
rockvanisher 2 years ago
Probably not.

brilliant. perfect for hybrid cars too.
