It’s pretty cool that they invest in more moving parts to make that happen, though it may be more about making emissions better at lower speeds than making more power at higher speeds.
I see you showed this concept for the intake; do they not do it for the exhaust as well?
Just on the intake for the engines described.
It would be extremely complicated
wut?
You should definitely get more attention. You just explain everything calm and nice, if you weren`t a youtuber or engineer, you would be a good teacher aswell. =)
And the moments when you can afford to change apex seals on a regular you just delete it and make as big of a Peripheral Port as you can!
Woah!
You are telling me that there is a rotary engine that works on unicorn technology? My life is complete
It’s worth noting that the older motors, such as the 12a do not have that variable intake… Unless mine was somehow removed.
This actually is similar to variable lift in a piston engine. Although, certain DOHC VTEC engines have variable lift on the exhaust valves as well. Good video though, I didn’t know this.
So that’s why the power band is so high in the rotary engines. I wonder if deleting the butterfly valves from the rotary would damage the engine any? Or would it just not pass emissions but create more power in the low range?
It would make less torque and be noticeably slower. The runner is designed to increase intake velocity, which is good for making power. But as rpm increases, the runner can’t keep up with the air the engine needs.
On a regular engine where you see a max of 6k rpm, no problem, but power does begin to drop at the top
On a rotary where 8k is no issue, you need to sacrifice low end for a higher rpm runner, or compromise like mazda did
Well this is for the NA 13bs. The Turbo 2 model from the same generation as this engine uses a four port design where instead of two small ports with a valve such as this one there is just one larger port since the turbo is there to fill in the loss of torque, or at leas that is what i understand about it lol i’m not an engineer haha

holy brapping vtak
that would explain the lack of torque
