Linear Combustion Engine

The Linear Combustion Engine is designed to be an efficient combustion to electricity generator. The pistons are directly opposite each other and works like the shake flash light. An engine such as this has the potential to be 50-65% efficient and could power a hybrid electric vehicle like the Chevy Volt. Check out http://www.lceproject.org/en/ for more information.

and what do you mean by Free Piston?

[jasbcor]

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

[rockvanisher]

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

[jasbcor]

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.

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 will never happen shakes too much good idea though

[utubehayter]

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?

[DanFrederiksen]

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

[jasbcor]

Probably not.
