alternate engine design

[blown]

just a quick question i hope some one can answer, a few years ago i came across a drawing of an internal combustion engine that was shaped like a shere with an out put shaft and internal vanes (that created the compression) it was also had variable compression properties, can anyone direct me to a link or know where a copy of the working plans could be??

You may be thinking of this. It did the rounds of the engineering press (at leastin the UK) for a while and then sunk without trace. The link isn't good, but it does have contact details on it.

Nope,that's a wankel. Old technology. The OP was asking about a new idea.

it was definatly a shere (new design) not a wankel, im sure it was on this site that someone had posted a link (few years ago now)

sorry i ment sphere shaped (ball) with 1 out put shaft sticking out

Blown. A year or so ago someone put an engine on this site he thought should be modeled. I was going though a stack of paper work and came up with his patent. US # 4949688 This may be what you are referring to.
This IC motor has serious draw backs. I mentioned some of them on the thread at the time. Can not find the thread now. Prehaps it was removed.

thanks ccycle, iv found something similar to what i remember it is pat # 5336067 thanks again

 

[blown]

thanks all, i found a us pat # 4024841 which is the one i remember, does any one know if this design would be efficient, seems to have a lot of moving parts

Here in Australia, the Sarich Orbital Engine was going to be the next big engine breakthough:

The Quasiturbine also comes to mind.
