lately ive noticed quite a few people arguing about piston engines being a crapload more reliable, more effiecent (in terms of gas mileage and the mechanics of the engine as well), and easier to work on than rotaries and i tried to argue with them about it, and well i dont really have enough knowladge about them to do it well enough.



and if you disagree or agree with pistons being a more efficent and easier to work on platform than a rotary could you state your reasons?

rotaries are better. They dont jerk up and down like a piston. Less moving parts, higher reving takes more abuse and the only problems i seen is taht its eats up a lil more gas than pistons and lacks some toruque. BUt what i always say. How many companys are working on improving rotay technology.



Piston:2834720934592184920348

Rotary: 1 (Current)

its all depends on what u are looking for out of the engine.

****-LOCK!!! lol



I'm staying out of this argument... https://www.nopistons.com/forums/pub...#>/biggrin.png

I personally like the rotary over a piston engine..however both will turn to **** if not treated correct or tuned the right way.

Apples to Oranges, man

My mechanic is building a GT3 car in his shop it is powered by a 12A bridgeport. When I asked the owner of the car why. Simply put. More bang for the buck. He said he did the piston engine thing in his racecars and they need to be rebuilt after every 3 or 4 races. He can run 2 to 3 seasons on a well built rotary.



Why did I choose a rotary?



If you have to ask you'll never understand. <--I love that phrase.

i like the rotary because i hate valves and pistons and timing belts and cams and stuff

I don't want to get to technical in the general discussion forum. But if it's not a rotor is not a motor to me. I have said this before and I'll say it again. The world goes round and round not up an down. We live in a rotary solar system. What goes around comes around............ We could argue all day it's all up to preference..

**Cues old 80's hairband song...**





Round and round.. What goes around comes around... I tell ya why..





Was that RATT or some ****?

THATS A NEW PERSPECTIVE TO SEEING THIS TOPIC. which is very true the world revolves around rotative ideas and themes in science and engineering and valid in all resourcefullness of society. In some parts up and down is better than around, SEX lol

I beg to differ sir. https://www.nopistons.com/forums/pub...R#>/unsure.png

As far as being better on gas? My 88 GXL got better gas milage than my 91 Sable does (about the same size tank), and my 84 GS gets better milage than either. With my GXL I got close to 270-300 to the tank and with my Sable I'm lucky to break the 200 mile mark

well how much contact between metals is there between pistons and rotaries. err, or how many pistons would have to be in the engine, on average, to be the same as a rotaries?

only if they had rotary powered chicks...

i took my mom's sable on a trip 2 years ago and was pullin well between 300-400 a tank easy. that is highway miles to.

I've got the 3.8 V6. everyone on the Taurus/Sable board says they are lucky to get to 250 with their 3.8's

You guys need to see my running shoes...



They speak for themselves.

if you're talking about friction the rotary has the piston engine beat by many many miles, because the rotary doesnt have senseless reciprocation.

well the debate turned into him saying:



Like I said, make all the excuses you want to glorify it. If it were a better design, more companies would be using it.



Even GM tinkered with making a rotary-powered Corvette many years ago. Thank god that idea never made it to production.

ahh .. makes sense now.. she has the 3.0... your sable the equivalent of the taurus sho ?

Not that I know of. if I'm not mistaken the 3.8 was just an option they offered, but they are known for faulty head gaskets and like all other merc/fords, shitty auto transmission.



its still fat, heavy, and handles like ****. But it is good enough to cruise around on weekends with friends, take on trips (where it lacks in gas milage it makes up on shitload of room). It gets me through traffic fine and can hang pretty good on the Hwy.

the downfall of the rotary is that

1. it traps some unburned fuel on the trailing side of the rotor

2. the surface to volume ratio of the chamber is such that the rotary puts a lot more heat into the water and oil per hp



mike

Gm bailed because they could not figure out how to pass emissons. Their 1st rotary car was supposed to be the Monza in 1974. The EPA fixed that one. GM panicked and bailed on the engine all together.



When Wankel was selling his patent rights to other companies quite a few bought them. Back then it was a bargain to buy it because it was not a production proven engine. Mazda proved it can work in production.



Imagine how much it costs now.



I am gald no other company came out with a Rotary. Makes our cars so much more unique.

i think if someone else had a rotary, it would be a lot more mainstream, it wouldnt be so weird?

more bang for the buck, and since its so light better chassis dynamics.

also pistons haveto stop at the top and bottom and that doesnt make any sense to me. also less moving parts.

Id rather see it as unique rather than weird, thats mainly the reason I don't even feel like selling my FC because its not like all the others....... its different https://www.nopistons.com/forums/pub...IR#>/bigok.gif

Just to be devils advocate:



The downfalls of the rotary are not so bad. The Renesis engine has zero exhaust/intake overlap so there is no unburnt fuel in the fresh air charge.



And the rotary makes more HP per POUND or per liter of displacement than a reciprocating piston engine. Those may be a couple of the more tolerable reasons why the rotary add more heat to oil and water.



If FORD did not control so much of Mazda we would see more advances in rotaries than imaginable...



Just my .02

yeah, because overlap is the only factor when it comes to unburnt fuel carrying over to the next cycle https://www.nopistons.com/forums/pub...>/rolleyes.gif
