rotary engine

[Jay]

i dont think the rotory will be going very far out of the performance car field
i do think one day the 4 stroke will be phased out but no in the near future
like i said before a specially tuned exhaust for the 2 stroke will reduce the loss of unburned fuel but never stop it

a scram jet is an internal comustion engine
the same as a jet turbine is
while the jet turbine draws and compresses the air
and the scram jet forces the air in by sucking and compressing it(which cause great heat) due to high air speed
the combustion takes place inside the jet which then produces thrust out the rear (through a a properly shaped duct as you said)

yes and the compression and combustion still happens inside that tube

 

[bengee]

yeah i guess you are right... an internal combustion engine is combusting hte working fluid within the system boundaries... which is done in a scram jet...

but a scram jet is never gonna be used in a car anyways lol... good for planes tho... or i guess super sonic planes...

i agree that the 4stroke will not be pahsed out in the near future... but it will be eventually...

 

[Jay]

yeah scram jets are only going to be used for supersonic aircraft that will go in to the stratosphere or even higher to the edge of space

but still they need some other engine to get them up to there and up to speed

 

[bengee]

prolly a tirbofan ... what he have now would be fine for that... too bad turbo fans dont work well above some mach number i dont remember

actually they could sue a ram jet engine that converts into a scram jet engine to create a stable flight between mach 2 and 8

the ram jet uses a different nozzle shape thant he scram jet creating the different engine type... but below mach 2 conventional engines are needed... shouldnt be that hard in the next 50 years we should reach some type of engineering solution... maybe something completely different...

this thread is pretty funny lol
it starts out with "what is a rotory" then 2 strokes, 4 strokes ,Turbofan's, scram jets and ram jets

i agree in 50 yrs there should be much faster travel than there is no like only 1-2 hours from australia to USA instead of the 13hours it takes now
but to this they would have to leave the stratosphere and travel at like mach 8 or like you said

 

[bengee]

yeah i was thinking the same thing... not much more to say bout hte rotary... lol... got a bad wrap amoung 40 year olds... tho... all those failed cars that they remember...

oh eyah when i said htat the rot was more versatile i meant in performance car territory... as in placement and weight and bal bal bal

 

[Jay]

as it seems only mazda will continue it seeing as they have all but mastered it

i think all other cars companies are scared to touch it
or it wont make them enough money

 

[Thio]

They just don't wnat to spend some money into something like that because they need $$$, which shouldn't be the reason.

Mazda will dominate that market, so they don't have to worry about revenue

 

[bengee]

in a way it is bad for the rotary... without competition... only one type of rotary will be developed.. ideas that other engineers might have will not be included in the engines development... if mazda ever does a bad job... thats bad for all rotary lovers...

 

[Jay]

true
and if mazda ever decided to scrap the rotor(which i dont think they will for a long time) then there wouldnt be anyone else so the mazda would be extinct

 

[bengee]

and i would never think of mazda again...

lol... so the mazda would be extinct... lol

 

[Jay]

well in my eyes if there is no rotor there is no mazda

exactly what i meant too... just thought it was funny you skipped from rotor sirectly to mazda like you didnt even mean to

 

[KT_Mazda_Fd3s]

right..now im confused!

 

[bengee]

basically ignore everything after i said on the first page... lol... after that we go off on a lil tangent

 

[FusionS2000]

I read somewhere that the FD3S is only rated as a 1.3 litre engine (stock of course).
Is that true?

 

[Jay]

its a twin rotor 13B
which is 1.3L or 2x 654cc which i suppose is 1308cc
each rotor is 654cc

 

[bengee]

yep... you are right viper... ithink for insurance purposes it is listed as a 1600cc or 2600cc forgot... one or the other... i am tired.... if someone doesnt correct me tonight i will fix tomorrow... i guess it jsut means that if you were to comp it to a standard piston engine i would have to be alrger capacity engine in order to create its horses...

yep that is true

ive driven a few 13B's and even the non turbos go pretty good
i havent driven any non turbo piston engines of similar capacity that can go like that

 

[bengee]

lol weve stopped arguing... or rather i have stoped being wrong lol... or maybe you have just stopped pointing out my errors... ehhh... i try to be as correct as possilbe on these things...

 

[Jay]

you did bring up some good points

 

[bengee]

lol thanks...
