Why isn't the Wankel engine type used more instead of the standard Otto types? Mazda axed it in early 10s IIRC
Wow this engine sure is niceODO rolls from 79999 to 80000BOOM
emissions. according to politicians, pollution is a threat to our democracy or something
>>29062031Air go in, seals come out that's what Wankel ownership is all about.
>>29062031
The MX-30 R-EV uses a tiny cuck wankel engine to serve as a battery generator o algo.
>>29062031Whats good about them exactly?
>>29062049I despise gay hybrids
>>29062051REEV aren't really hybrids. The electric motor does all the work, the range extender only produces electricity when the battery goes low.
>>29062050Less parts.No camshaft, valves, rocker arms, timing belts, or timing chains either. It's really engineering in it's purest for. There are downsides with heating and some oil and gas slipping out to get burned.
>>29062059Electric motors are simpler.
>>29062050>Whats good about them exactly?1300cc - 231hp @ 8500 rpm isn't enough?
>>29062058That's a series hybrid as opposed to a parallel hybrid where the ICE and electric motor both drive the wheels. Both are classified as hybrids.
>>29062060Yeah but EVs are shit due to lackluster battery tech.
>>29062060Just because something is simple don't make it good, look at Americans.
>>29062062In a series hybrid the engine would produce the electricity for the electric motor but in EREV the battery is charged via plugs and it operates like a normal tesla until you need to extend the range.
>>29062049>MX-30 R-EVDidn't that car completely fail to sell?I can respect Mazda for releasing something so unusual, but the wankel engine wasn't that good and the EV part fucking sucked.The PHEV's electric range was 85 km on paper, but more like 50 km in less than ideal conditions. After the battery ran low, it was basically the least efficient hybrid car on the market, managing something like 10 L / 100 km (~23 MPG) or worse.With that consumption and the small tank, many pure EVs could out-range it. At least in the EVs you didn't have to listen to the 75 hp wankel screaming as it tried to keep the car moving.
>>29062035This, "HC emissions" IIRC.Also->Fuck all bureaucrats and politicians right in the ass with a running chainsaw. A poorly tuned one so they get to enjoy the castor oil and unburned gasoline smell as their shitpipe is rent asunder.
>>29062031Low torque, poor fuel economy, high emissions, higher maintenance costs(?) etc., etc.I think the only real advantage is power density and packaging, but otherwise they don't have much practical use when compared to regular piston engines.
>>29062124>higher maintenance costs(?)Id assume it be much cheaper because less moving parts.
>>29062129That is just not true in reality if you look at crate engine prices.
>>29062129Not really. The additional moving parts in a piston engine are essentially maintained by oil and as a result don't have individual maintenance requirements, they just add weight, friction, and are harder to package. Piston engines have routinely proven to last over a million miles with just fluid and belt changes, whereas Wankel engines will without a doubt require rebuilding many times over to achieve that same goal, regardless of how well they're kept. Add to that the need to follow the same regular servicing that a piston engine requires, and it I can very much see a Wankel costing more to keep alive over multiple decades. They're not exactly difficult to rebuild, mind, but it's still a significant cost to the average NPC who will need to pay someone to do the work for them.
>>29062061Nice nice, now how much torque does it make?
>>29062163If torque was relevant, everybody would be driving EVs.
>>29062163Buy a Tractor farmer-kun
>>29062163let's seerx-8 232hp, 216 Nm -> 6.3svw golf mk7 gti Performance Package 230hp, 370Nm -> 6.2sdo you know why your post is irelevant?because you don't know what torque contributes to a car.
>>29062095What happens when you need the extended range? The engine produces the electricity for the motor.
>>29062163Wheel torque is all that matters, and that is a function of engine power and road speed and nothing else.
>>29062031>in the early 10s gosh im getting old
>>29062049Fuck off back to the shart, youre not welcome here.Faggot.
>>29062034>>29062036>>29062042Are you a bot or are you just this autistically committed to pretending things bout rotary engines?
>>29062059Those are actually not good points.The port configuration acts as the cam/valves and are extremely difficult to change. Thus the engine powerband is built in to the design and cant be readily altered for different applications.
>>29062209Don't you have some apex seals to replace again?
>>29062214Answer the question, loser. It's not like you have a job to get to.
>>29062220Nta but >LM fucking AOGo on any dorito forum and the answer is "a rotary (should) last 100k miles before the apex seals fail".Thats from the people who cherish and build this dead end design.
>>29062204t. Prius fart huffer
>>29062318You can suck my 6.6L.Faggot.
>>29062065so does this mean we can all agree roturds are objectively shit? because I'm not seeing anything good about them other than them supposedly being simple.
>>29062318I liked the prius before they tried turning it into a gay ass fake ferrari
Rotaries sound SO bad. Not a huge deal, but it deserves to be said.
>>29062031The answer is emissions, which is due to total loss lubrication. Oil doesn't burn as cleanly as gasoline. Same reason why we don't have two strokes in anything street legal anymore, outside of a few 50cc scooters that barely have emissions.
>>29062609There are some euro 5+ 300cc dual sports from Beta/KTM arent there? Or did they get the axe without me noticing
>>29062659No, at least not for betaI have a street legal 2 stroke beta but it wasn't legal from factory
>>29062662Google says they remain street legal in Europe, but not for Japan or America.
>>29062666huh, didn't know that
>>29062659Pretty sure KTM doesn't. All of their plated bikes that are currently in production for the Irish market are 4 strokes. Might have missed one though. Definitely a decent number of older ones, but I'm more talking about new production. If I missed one, would be interesting to hear who's still making new street legal 2 stroke bikes.
>>29062061But they guzzle fuel anyway don't they?
>>29062059The supposed benefit of simplicity is greater reliability.But these engines aren't reliable.
>>29062035If pollution is a threat the how come products come tripple layered in plastic packaging?
>>29062753Because those emissions happen somewhere we don't care about of course.
>>29062059You get all that with a 2 stroke and it is easier to fix. Wankels are a meme.
>>29062303>projectingWeird how all the rotary guys I know have well over 100k on theirs. So be honest. Did a rotary guy steal your girl?
>>29062752You're confusing longevity with reliability.Longevity = the total length of an engines life without needing major repairs (being pulled from car)Reliability = number of (or rather lack of) potential problems that could effect running operation of the engine Now a rotary doesn't have a very lasting longevity, at most could get 250k miles/30 years out of an NA rotary, which is decent for a Japanese sports car and better than many euro cars, but not compared to a hilux or camry etc.As for reliability, well there are very minimal problems, in fact hardly any, that can go wrong in the day to day operation of the engine. 80s/90s turbo rotaries are different but well that's because they are 30+ year old turbo setups of course they'll have problems regardless of engine.
>>29062031frictioni just invented a design that eliminates all apex seal friction. i solved the wankel
>>29062753because people haven’t figured out yet that dietary microplastic isn’t such a good idea
>>29062878No i'm not. You're making up bullshit definitions based on nothing.If the car regularly needs engine rebuilds it is not reliable. It doesnt matter how many things could go wrong. It matters if they actually do.
>>29062906>every 20-30 years is "regularly needing rebuilds"Kek. And yes you are. Words have meaning, use them correctly you esl nigger.
>>29062031Burns oil and apex seals get beat to shit on bumpy roads.
>>29062878>>29062909the fact that they didn't hold value like the rest of the JDM would suggest they aren't lasting 250k miles or 30 years.
>>29062927>hold their value FDs are more expensive than everything other than the NSX/R34 GTRFC RX7s are more expensive than STI/EVO/every model of RWD SkylineSA RX7 is probably the priciest early 80s Japanese car, other than a mint condition rust free AE86
>>29062927>>29062929And then there are genuine RX3 coupes and just LMAO they are basically R34 GTR prices
>>29062929>FDs are more expensive than everything other than the NSX/R34 GTRThey aren't more expensive than A80 Poopras, Aren't more expensive than R33 or even R32s and aren't more expensive than EVOs besides the early 90s ones that have crankwalk (coincidentally, another car that also isn't considered reliable or long lasting like the FD itself). FCs aren't more expensive than 80s poopras, either. or 80s skyline GTRs before they officially became "godzilla". They're even less expensive on average than the 80s Z.you're delusional and you can verify all of this on classic.com which tracks the average price of classic car sales.
>>29062932also wrong.
>>29062939A good condition Series 8 FD is an 80k AUD car.An R32 GTR is a 60k AUD car.No model of EVO is worth more than 40k.Even a MK4 Supra rarely pushes above FD prices in Australia.
>>29062939Also no one gives a single fuck about burger prices.>>29062940RHD RX3 coupe is a 100k+ car every day of the week.
>>29062939Also the FC RX7 is a 40k car and every model of 80s skyline is worth less except a GTSR but they are unobtainum.Average R31 skyline is like a 6k car lmao.
>>29062878"Yea its really reliable, it runs perfect for 20 minutes."
>>29062031Longevity and emissions. Apex seal travels ~8x further than a piston ringMazda's metallurgy experiments made apex seals that last longer, but that was also translated to piston rings so the basic longevity gap between rotary and piston engines stayed the same
ITT:>delusional dorito fanboi that screams "just as good!!" while calling his mom over an intercom and bitching that she hasnt brought him his chicken tendies or emptied his piss bottles while the rest of society brings up actual facts
Not interested in hearing the opinions of nocar redditors who say shit like "boost in apex seals out 80k miles kek".
Disregarding hydrogen fuel costs and infrastructure, does it actually make sense as a rotary fuel?
>>29062031It's hard to meet emissions legislation with them becasue they burn oil, have weirdly shped combustion chambers with a terrible surface-to-volume ratio (whole lot of HC and CO because of flame quenching) and the ports lead to a fixed timing (the latter is why Mazda managed for a serial hybrid setup)>>29063359the higher flame speeds help a lot with the flame quneching issue, but it'll still be inefficient and burn oil.
>>29062031You can't really do variable valve timing or lift with a dorito. these are important when you're trying to squeeze the last bit of performance and emissions from a street ICE.
>>29063087Thats not plebbit tier.Thats just the experience of rotary owners.
>>29062163Torque is just a function of gearing
>>29063518>t. Semi truck with an 800rpm powerband and 18 speed gearbox.
>>29062163More than enough to push the car
>>29062985>Cuckstralia is the only place in the world where an FD is expensive, and even then, these are just numbers pulled from your ass with no data to track averageswew>>29062986>Also no one gives a single fuck about the largest buyer of JDM in the worldholy fucking cope. you rotards are hilarious.>RHD RX3 coupe is a 100k+and yet, there are two that recently sold for 50k. is there a single R34 GTR that has?>FC RX7 is a 40k car those turds are worth about 20k everywhere else in the world. i'm assuming you mean cucked ass australian prices. which does not reflect reality. a fucking basic bitch mustang is worth a shit load of money in australia. do you think we should go off of that as the baseline of what they're worth in general?>>29063087this, there's one nigger who regularly seethes as pushrods, but where is he when rotards climb out of the woodwork to pretend their shit cars are anything but garbage.
