Compression Charge Recirculation Engine Load Control
Compression Charge Recirculation Engine Load Control - New Patent for Rotary engines to help increase HP and better fuel economy. Don't think it's a repost, correct me if I'm wrong.

Here ya go.
Saw this a year or so ago. It seemed rather nifty.

I'm just curious if it will even work as intended. Since I don't know physics or have a degree in engineering, what is going help push the air/fuel up into that extra chamber up there? wouldn't the pressure difference just keep it going along it's natural route? Also, wouldn't it be a bit harder to tune the cars with that?
Just my uneducated questions.

^1. Thanks for posting that. Much appreciated.
2. I would guess if they have a patent on the technology, that it has been tested from an R&D stand point. Something this radical would almost certainly have to be included on a new rotary variant (possibly 16X). But anything is possible.

How do they plan it to work? It looks like while idle/light load, additional fuel gets passed through the upper route, but that seems to me like the same thing as tuning it to run a little more lean..?

^good point, I wonder if it works like an expansion chamber on a paintball gun. Id be interested to see how this could work with an FI setup. After watching the vid a few times it makes sense how this could improve the rtry engine. By keeping air circulating there seems to be less loss of momentum. On a side note; wasnt there another patent said to increase co2 emmsions and power in the use of aircraft engines by altering firing or somthing. I remember the thread a few months back

Maybe that's exacty what it's for, a different way to lean the car out. Taking some of the extra fuel out would help emissons. And maybe by mixing in the already mixed air/fuel back into the combustion chamber at low rpms will give a better burn and increase low-end torque.

well, according to the description it says it increases torque. which is nice.
but i'll bet $5 we dont see this on the 16x. that engine is for the most part already done. they either fix the problems they have with it or scrap it. i doubt they will be changing the housings for something new.
its not a mazda patent, mind you.

Usually you only want a patent for majority of cases if you plan on making a prototype to follow up on it to guarantee that the idea stays yours. Otherwise, someone else can easily ****** the idea even if patented, and slightly change something on it to get outside the loophole and claim it as their own.

I may be wrong but it's very hard to just patent an idea and not a prototype. This is because anyone can make up something and claim rights on it and never make a prototype. I think someone would only do this attempting such if they planned on selling the rights to someone else but I believe this is quite hard to do.

Looks like they're effectively lowering the compression ratio at idle/light load by leaking the fuel/air mix from the rotor face while it's being compressed.. though that by itself would lower torque, not raise it. Would help clean out the pocket of over-rich mixture at the back of each rotor face though, helping fuel economy.
Wait, I think this is supposed to replace the throttle body. The little valve is open when in our cars the throttle is closed, so each face makes little compression... just enough to idle I suppose... then if the driver presses on the go pedal, the valve closes, increasing the compression and making more power, so spinning up the engine. Nifty. Could be a lot more responsive, but the fuel efficiency could go up a lot. Clever!

This is basically atkins cycle rotary. Absence of throttle plates vastly lowering pumping looses and effectively, expansion is longer than compression-which is good thing. Similar system is using toyota in prius engine and honda in certain engines-at low load, intake valves closing is delayed the point, where quite large part of fresh charge is escaping back to intake... but these engines have higher CR ratio so it would be very interesting how it would work in rotary...
