Machines | Do Rotary Engines Have VTEC? Wankel VIS

Do rotary engines have VTEC? As far back as the rotary engine in the 1985 Mazda RX-7, rotary engines have had variable induction systems for greater power at higher RPM, and a more efficient burn at lower RPM. At low RPM in the 13B Wankel engine, only two intake ports are open for each rotor housing. At higher RPM when the engine load is higher, a third intake port opens up to allow for greater airflow. With more airflow, more fuel can be injected, and thus the car will create more power. The Mazda RX-8 uses a three stage variable induction system which further improves upon this idea. At low RPM, only one port is open. At mid RPM, an additional port opens for greater airflow, and at high RPM, 3 ports open for maximum airflow and power.

Hey Jason, do you have a video on Desmodromic valve drive?
-
Any idea why the rotary engine design isn't used in refeigeration?
-
Can you please also explain what is bridge port and the pros and cons thank you
-
Could you do a video on the Koenigsegg V8 engine used in the Agera? How did they achieve over 1000HP with half the cylinders of the W16?

I've experienced cruising in a Nissan with a continuously variable transmission (CVT). The extraordinarily low engine RPM at cruising speed made for some impressive fuel economy.
I'm wondering if pairing a CVT with a Wankel operating at low RPM would be light weight enough to be economical. So, I guess my question is, since I understand that piston engines tend to bog down at low RPMs, is Wankel efficient enough to run that slowly?
Looks like a marriage made in heaven to me. -
Perfect! ... a small 3 minute vid straight to the point bite sized info job done! Thank you again!
-
VTEC is only in VTEC engines... you mean VVT
-
can there be more than 2 rotars?
-
So... Does Wankel have VTEC or not?
-
Can you do one about old aircraft piston rotary engines and how their blip system works?
-
Do you even, vtech bro?
-
Can forced induction and placing a 3rd ignitor at the middle of the combustion stroke would be of any help to burn the mixture properly ?
-
You are very knowledgeable when it comes to the rotary engine .With that being said I could almost guarantee that you could make changes to make that wonderful little power plant more economical and efficient .

Why is he calling Mazda engines Mozda?
-
only talks about side ports,not perheriple ports LOL
-
rotary motor in a racecar???

Dude, love the videos, and the new shirt and 'do :P

I just recently watched the video on the 4 reasons why the rotary is dead, and the main problem was fuel economy. That being said, with only one port open at low RPMS, does that mean that it is getting worse gas mileage at higher RPMS because all the ports are open, or does it compensate for the faster turning of the rotor?

Very interesting and well explained. The emissions effectively killed this wonderful engine and the difficult seals, so if in the future one could solve these problems, it may be competitive again, right? Diesel has oil in the fuel mixture, would that not be sufficient to lubricate the tips of the rotors and avoid having to inject oil to burn and ruin the emissions? I know NSU, Mercedes, Fiat and even Norton motorcycles have dabbled with the Rotary engine and given up, therefore I am sure they must have considered all the options before relinquish their interest. Thank you for the info.
