A small correction: the Apex seal does not move uniformly across the epitrochoid, it instead moves at a variable speed throughout the sweep of the rotor, further complicating the lubrication and sealing issues.

@godofrock

My family had an rx2 and we changed the apex seals every 30,000 miles. After the first time breaking down the rotary it was a breeze. We put a side draft webber carb on to replace all the emissions and complicated intake. We could start removing the engine at 8am and have it back in and running with a fresh rebuild by noon.   The only engine easier to work on was my 1970 vw bug. After 250,000 miles on the wankle we could not get replacement parts and had to sell it.

@law-abiding-criminal

Can you also make a video about the liquid piston engine

@mrslowly9985

The main issue with the Wankel is that people treat them like normal engines.  Rev it when you start, and rev it when you turn off- get that Oil flowing!

@meandthecat4025

The language of the paper at 2:14  isn't German but Dutch, like Netherlands. 

Quite cool Dutch innovation hit the street with rotary engines!

@sacriptex5870

amazing video, great search and care on content, conglatulations

@briandavis414

8:20 That'sfailure one hell of engineering failure...

@bradgreen987

Even the best version can't last 100,000 miles. Garbage 😢

@chrisnewman7281

The problem with these petrol driven range extenders, is that people get lazy and run the car on fuel alone and aside the use of the electric motor. The other issue is that the vehicles going to be quite a bit more expensive to maintain given that you’ve got drive trains for the electric drive train plus the Wankel engine.

@acgsamson6934

Why don't they reverse the shapes so the two circles go inside the triangle instead that way they won't need the things at the end of the triangle. they could just make some small insert inside the triangle shape so the chamber can explode. Sorry for my lack of lingu.

@johnepavek

Legit question, does anyone know why you can’t use a roller bearing as an apex seal?

@pmsteamrailroading

I still think a gas turbine electric hybrid would make a great car. 
The flaw of turbines has always been slowing them down to drive a car. 
But if you design it for one speed and use it to charge batteries, the reduced moving parts, and ability to burn anything would make them the best answer.

@fhw.5182

if i am right we may se someone take 2 of these 800cc rotary and make a 1.6l twin rotor engine!

@kenmore01

To all of the EV lovers, please remember what happened to Diesel fuel in the '70s. It was cheap. People bought Diesels in droves. Guess what? Diesel prices soared. Guess what will happen to electricity prices soon? Don't  get me wrong, it won't be too soon. They want to let us all be comfortable in our EVs and their "cheap fuel" like fattening the calf. Once we're  committed, bang! Just watch electricity prices spike!

Go ahead. Join the cheap electricity car brigade. Don't say you weren't warned.

@Potato76577

Have you ever seen a meltdown from that engine before?

@Monstacheeks

Turbo seals are much worse than apex seals.

@briandavis414

Still apex seals, and heat?.. seriously??

@G3rain1

Okay, but how TF does the big gear stay on the small one?

@Richie_

That chatter looked bad.
