pick rotary engine

A design for an internal combustion engine, two pistons placed on polar opposites around a fixed axis spin inside a chamber. Two gates create four chambers isolating each stage of the Otto cycle. All four (4) stages occur per one-half (1/2) revolution. Stacking these chambers along a common drive shaft at different angles allow the air-fuel mixture to be loaded into the adjacent chamber by means of a sliding gate valve. The end result is pure rotary action.

The problem the at the compression stage, the fuel/air is compressed very high before gate for the ignition stage(a danger of the fuel/air exploding before in ignition stage(that means that can stall or suddenly go into reverse))

That engine is a death trap.

It is possible to adjust and maintain a fixed compression ratio by virtue of the offset between modules. The knife gate opens as the expansion (explosion) chamber begins to draw a vacuum so that the air+fuel charge passes into the expansion chamber in a constant volume process. That being said, it would be difficult to estimate safe compression ratios without real world testing.

We have not attempted to build this engine. Expected estimate cost from prototype to production would be ~80 - 240 million CAN.

Sealing is done using apex seals at the gate edge and micro labyrinth seals along the plate edges. Tune back in 1-2 months for a follow-up video detailing the gate cam mechanism.

Nice idea, but: inefficient combustion chamber shape (way too much surface area) and the basic problem of most of the new engine concepts; the problem of sealing the gates. How is it done? I liek the modularity.

@bipervids Really 80-240 Million, shit I can see a prototype costing no more then $500,000 American, and thats if you dick around and mess up a few times.

check out my engine. i've solved problem of ur engine completely

[sirtone69]

The design is flawed. It wouldn't work.

Why don't build a working model of that engine?

[thegreatkoua]

yeah when are we going to get it

[mattmorr]

I really like this engine, thanks for uploading it. I wonder sometimes how the wankel engine survived so long, I'm sure there are better engines out there like this one, they just need to get to the proof of concept stage and then get some backing.

The knife gate actually lets the flame come in from the rotor next to it, which helps ignite the fuel/air mix, no pressure is lost.
