those seals or rings , not plates ( apex-seals ) as in a Wankel
if you look carefully, you see 12 ignitions per rotor revolution. A wankel has 3 ignitions. This rotor is therefore rotating 4 times slower slower and the seal-rings do not cause "devils marks " as in a wankel-rotorhouse. They are...
I saw a forummember with the name HiPerTEC
Is this name ( identical written ) related to High Performance Toroidal Engine Concept : http://www.hdcreates.com/websites/ATS/pages/HiPerTEC.html
Are the Russians going toroidal ?
Billonaire Mikhail Prokhorov has made an investment that involves a total outlay of 150 million euros.
It seems to be a hybryd toroidal , similar like the omega-engine from Bradshow...
yes you right izzmus, blow by in the exhaust chamber is not so crital, blow by in the compression is.
Cooling is not difficult but very, very omportant.
Further : It seems that Ford also is playing around with a free opposed piston engine. They also lubricate their pistonrings with a injected...
I know Greglock , suppose he putted his drawing in 1920 on the internet, ...
For your information, I have a small other prototype running in my motorhome working as a generator .
Wankelrotor can be considered as a free piston, there is no side thrust. But this rotor is continuously heating up.
Machining a trochoidehouse within tolerances is not really conventional. What about honing, lapping. ?
The Wankelhouse has an unequal thermal expansion. Its continously heated on...
absolutely right about de Wankel apex seals. The space to mount a seal between the compressionchambre and expansionchambre is awful limited. Blow by, however, is not so critical, you simply loose power . Blowby in a conventional is worse, it's towards the crankshaft.
The biggest problem in a...
cilinderoffset : yes that's the way to reduce side-friction during expansion and alows a bigger ( but more accepatble ) side-friction during compression.
Talking about motorbikes ( driving a Yamaha Fazer myself ), this dutch dieselbike is also free-piston.
Love it ...
