Recently had the chance to disassemble a 13B-DEI as a side project, probably one of the easiest engines to service ever.
Sadly it was fucked required new housings and rotors, It had been sitting outside for years and collected water inside the chamber rusting out the rotors.

Why do you think they break so often? Rotating mass is a serious issue.

nice meme there dude.

Let me present you something more interesting and factual.
Hunter Murphy
Is this the best engine configuration ever conceived?
Austin Walker
Have any of ypu read about that rotary x engine from liquidpiston? I saw it on the news a few weeks agod and thought it was kind of neat. Does it have the potential to go anywhere commercially or will it be regulated to niche applications
Yes, this is what i was talking about. Is it as exciting as they claim it to be, can it actually be scales up to work with a car or motorcycle
Jackson Powell
A rotor is significantly larger than a piston and made of steel rather than aluminum. If you want light weight, Mazdatrix was selling 5 pound titanium rotors for $2500 each.
Jayden Long
>Rotary OS God forbid such an abomination be created or loaded into a PC
Dominic Sullivan
But those rotors do not change direction like regular pistons. Also the crankshaft is much simpler and no conrods are needed.
Also there is three sides in those rotary pistons so would it be fare to compare it with three regular pistons with conrods?
Hunter Brown
It's still significantly heavier than three pistons with rods, but not having to change direction counts for a lot. Plus, the closer the mass is to the center, the less it affects moment of inertia.

Connor Green
How heavy is the 13B flywheel compared to similar power regular engines? Does the rotating pistons have any effect or are the flywheels weighin the same?

Typical
Carter Diaz
A piston has to totally change direction, a rotor does not.
The rotor merely spins and a lot of the mass is closer to the point of rotation reducing the moment where as a piston is rotating up and down about a point along a rod far from the peak of oscillation.
Basically put the piston is experiencing far higher forces and moments of inertia which is why rotors pretty easily rev up to 11-12k RPM's with very little done to them despite being 5kg whereas pistons at 400g require a properly, high-quality engine build to even get close to those numbers.
Nolan Parker
What kind of horsepower can you get from a street-ported 13B? I'm thinking of getting an old beat-up FB to turn into a weekend hoon machine/track whip.
Connor Ramirez
I hope you're not counting on running that plate. It's fucked. Street ported NA is good for maybe 150-180 at the wheels depending on how aggressive it is.
James Fisher
The flywheel is significantly heavier than a typical I4 or I6 sprtscar flywheel because it has a counterweight built into it. The aftermarket lightweight flywheels are much lighter than normal because they're designed to bolt to the counterweight from the back of an auto trans engine. It's hard to compare.
Yeah, that's my point. 22 pounds of pistons and rods would be insane for anything even remotely sporty. 22 pounds of rotors isn't that much because they never have to stop and turn around.
Jonathan Morris
Depends on the type of porting and how aggressive it is, probably in the realm of 170hp or so..
Generally 12A's/13B's don't break 200hp naturally aspirated without some serious shenanigans.
I wouldn't worry too much if you're just after a simple track or hoon machine, the FB is very light to begin with.
Dylan Gray
>Take rotary >Turn inside out >Most efficient engine ever designed
The dorito is literally the inverse of a good engine
Robert Adams
It's worth remembering the rotors spin at a third the speed of the eccentric shaft. So at 9,000rpm the rotors spin at 3,000rpm.
Adam Wood
>most efficient engine ever designed >because some faggot said so
Let's see them build it and actually use it in a car then.
Christian Johnson
Needs to be properly scaled and tested in a car.
I'm not holding my breath until they do.
Jeremiah Williams
It won't work in a car. It's a steady state engine like a gas turbine. It's designed to work with a generator or hydraulic transmission
Isaac Myers
wow that's heavy so much rotating mass that rides on a steel squigy for compression. Back to the drawing board mazda
Dominic Ramirez
They can fuck off with it then.
Thomas Walker
>being literally retarded
Wyatt Allen
>mazda literally went back to the drawing board
Jack Rivera
>what you mentioned has literally never been a problem with rotaries and mazda is changing other things
fuck off tard
Carter Young
Did you guys know a piston weighs 500 grams? (around 1lb for you yanks)
Cameron Edwards
>compression and apex seals have never been a problematic on rotary
ermergerd butthurt rotard lol
Daniel Rodriguez
no
Thomas Myers
what's the compression ratio on naturally aspirated rotaries? RX8 specifically but i'm also interested in SA22 and FC
not the best video but it at least proves the concept works. you can't really verify the efficiency claims until they become more commercial or you spend like 20k on a prototype
Jack Evans
The weight of the rotors is a meme issue, low polar moment of inertia.
>rotating mass that rides on a steel squigy for compression. Back to the drawing board mazda >>compression and apex seals have never been a problematic on rotary

>100 hp at 9000 rpm
Carter Price
HAHAHA HE SAID IT AGAIN THE MEMEME A P E X S E A L S APEX SEALS APEX SEALS LISTEN KID YOU DON'T KNOW SHIT YOU'RE FUCKING OUTDATED PISTON FUCK CAMSHAFT FUCK EXCUSE OF AN "ENGINE" HASN'T GOT SHIT ON MAZDA'S ROTARY ENGINE. I'LL WANKEL ALL OVER YOUR MOM AND STILL HAVE ENOUGH JUICE LEFT TO SMOKE YOUR ASS ON THE STRIP. MAZDA HAD TO STOP PRODUCTION OF THE ROTARY NOT TO PUT EVERY OTHER CAR COMPANY OUT OF BUSINESS AND CAUSE A GLOBAL DEPRESSION. So next time you even think about spouting le apex sealyio maymay you better think Twice.

How hard is it to change the apex seals though? Is it like changing the oil, or do you have to completely rebuild it? Are rotaries easier to rebuild? They look like they would be simpler to take apart but idk.
Jackson Scott
There's essentially only three moving parts.
Michael Myers
To change the apex seals you are required to tear down the whole engine to access the rotors. However, rotaries are simple to tear down and can be rebuilt quickly after a repair or upgrade. Depending on experience and what being worked on, it could be easily be done in a day or less. It's literally just a big sandwich of 3 iron plates, 2 aluminum housings, and 2 rotors.
Hunter Cox
Where does the oil go?
Ryan Perez
Into a Jerry can with the gasoline
Asher Ross
what do you mean where does it go, like where in the engine?
yea >best sound (some v8s are better) >most simple >perfectly smooth, no balancers >looks best >takes boost best >makes most torque because pistons push thr crank a full 120° unlike v style
