Why is there no rotary diesels? Is it possible?

diesel doesn´t create torque by itself, you need boost for that

Do you have a source? Would be interresting to see how it worked.

>inb4 mazda's booty-blasted that Rolls Royce beat them to it
Also reminds me of the 2.5 rotor engine that some RX8 enthusiast theorized about

So turbo'ing the engine would be the solution.

Rotary engines don't make excellent compression to being with like a piston could. The mating surface between a rotor and the wall likely wouldn't produce enough pressure for adequate combustion.

Gotta admit that's pretty clever.

>not wanting a 12 piston, 6 cylinder, 2 stroke diesel instead

I certainly wouldn't mind having that cut through the bonnet of my shitbox.

I still like the idea of a perfected rotary.

Source? That sounds hilarious

>They have plenty of torque.

Probably don't support high enough compression to support combustion.

Not for a compression diesel. There's no point in a rotary's cycle for diesel to combust without spark.
You can give a diesel spark, or run the engine at higher temps. But eventually you're just replacing gas with diesel, and you might as well just use jet fuel at that point.

>And already rev high.
examples? you may be talking about some modified race engine that i don't know about but my only experience with diesels is heavy towing trucks. between 6 and 8 liters displacement, redlining at 4-5k rpm.

You can already break 7 grand on a regular four stroke diesel intended for luxobarges

>rotary with valves
Why has no one else tried this
Wouldn't that eliminate port overlap?

Jet fuel pretty much IS diesel. Most older diesels will run fine on jet fuel with additives added.

That was kinda my point.
A diesel rotary can be a jet fuel rotary.
Why not just make it jet fuel, which has a higher energy density?

A key benefit (that Veeky Forums never talks about) of Mazda's Wankel is the lack of timing and lack of cams. That's what allows a rotary to be so rev happy.

And it sounds dang cool, but I think that sound may be the only thing you get from it

FC3S NA 13Bs had variable timing via the auxillary intake port system

>Why not just make it jet fuel

...

Well then you probably shouldn't be thinking about rotaries at all

Diesel rotary would be cheaper and fix the shitty exhaust note.

You'd still have to repair it every evening, and upping the compression doesn't seem like that good of an idea in an engine where seals are already a problem.
Wonder if you'd need to burn oil in a diesel wanker tho

We already have consumer grade piston diesels that rev over 5000.

also, Diesel wankel engines exist already

>Wonder if you'd need to burn oil in a diesel wanker tho
the diesel would be probably good enough lubricant

>shitty exhaust note
fag

It wont "fix" anything, the exhaust note has nothing to do with the fuel burned.

>that
>not a man-rated diesel engine like a 16-645
>16 fucking cylinders, turbocharged

Pity you can't hear it reverberating off the hills. Shit was loud.

reminder that rotaries are the only cars that require mufflers at race tracks

>used to drive carbed 12a
>mfw even with the muffler it was noisy enough that nobody wanted to be in front of it on nature drives
>tfw drive miats now and stuck behind shitters going 5 in a 20 eternally

>Higher Revs
Higher than what?
What limits revs in a diesel is how quickly it burns.

>those thighs

sound shit like a vacuum cleaner
this is a better sounding train

Modern diesels with common rail engines and variable-geometry turbochargers rev just as high as petrol engines.

damn i hate being degenerate.

know that two things are unobtainable..

OPs pic and supercars..probably.

seriously i may have clicked this thread 3 or 4 times..

dont even know what its about!

and they both belong to god.

wankle diesels!!!

the hells wron with you man!

just buy a 335d and be done with it.

really? I thought rotards only thought about being broken

>links a yt video of a SD70 wich has a 16-710 and NOT a 16-645

all you need to do is have a temp+pressure+friction resistant tube in the cylinder.

fits like a sleeve, outside of it you have it liquid filled.

hey presto..

tell me why my sht isnt feesible.

then just replace the sleeve every 60k miles.

wankels are already lined with a coating that does that

those tits too

OP here. Thanks for enjoying the thread.

It's about what perks a rotary diesel would be and if it is possible to make one.
