Do Rotary Engines Have "VTEC"?

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?

It would be extremely complicated

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?

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?

that would explain the lack of torque
