    I think you guys need to ask Chris V this question.

  2. I recently became interested in the wankel engine after having been pressed back in a 3rd generation and started to do some research on it. Fascenating, a true stroke of genious by doctor felix wankel-or should I say rotor of genious(ok it was a bad joke). So efficent, a center of gravity so much lower than a normal car, and so much lighter with fewer moving parts. Also if properly maintained it will last longer than any piston driven car, and can be easily converted to run on hydrogen. General motors almost made the corvette a 4 rotor and ford almost made their whole line up rotors. So with so many good points and so few bad why didnt it ever catch on.<!-- Signature -->

    I think the big reason why the Rotor engine didn't become as popular is because there were alot of problems with the 3rd Gen Rx7. Like mine when I first got it, rumors said that if you drive it hard (me) it tends to over heat fast so I got new gaskets and a new intercooler to be safe. Some of these rumors were saying people dieing in there car because it would burst into flames but I dont really believe them. If they were true it might be why Rotory isnt popular...

    thats horse shit. the answers simple these are reliable engines they have used them in planes before. the answer is mazda owns the patent and wont let anyone use it
     
  5. Re: Why didnt the wankel engine catch on?

    The rotary didnt catch on because these are harder to seal and cool than regular piston engines. This is not as much of a problem in planes because planes do not need cooling at 30000 feet and also do not vibrate as much as cars going ouver bumps.
     
  6. Re: Why didnt the wankel engine catch on?

    Because it blows.-literally.

    WANKELS ARE VERY HEAT SENSITIVE, and the rx-7 has pitiful cooling.

    I know a guy down the street, it was about 98 degrees F and his engine blew-brand new car with no mods. PRETTY SAD HUH?

    damn tiger, how old are you. when did this guy blow the motor, 10 years ago, haha. cause thats when these cars were brand new. i really doubt thats a true story by any means. yo i know this guy down the street too, he is santa claus. i saw him with his reindeer last year. get a life man.

    123 wrote mazda owns the patent and won't sell it and is probably right. in the 60's and early 70's when nsu and later mazda were developing the rotor they had a lot of problems with seals and as a result reliabity. this remedied after the first mazda 10 and 12A motors by coating the inside of the rotor housings with chromium so the seals last longer. when younger had an RX2 with original 12A twin dizzy ( the unreliable ones) i thrashed the hell out of the 22 year old motor and could not blow the thing, just some smoke before i sold it. people say they are unreliable and overheat but they are very reliable as long as you warm them up EVERY time and of course warm down turbos. as for overheating they do not overheat but they do however run very high exhaust gas temp compared to piston cars. if you had poured money down a hole for years developing a motor would you just give away the design? mazda japan actually imported some HJ holdens from australia in the 70's to trial but the massive weight and poor fit and finish of aussie cars meant they sold in limited numbers in japan
