You say that a rotary is like a 4 cylinder, well if that were so the why does every chamber have 3 lobes? if it were a 4 cylinder it would ony have 1 per chamber and they would be pistons. because they effect of the rotarty action would be lost.
So If they were 4 cylinders then it would be like our V6's having 3 pistons in every cylinder sleeve. Thats why they are more like the 6 cylinders. They have 3 theoretical "pistons" per "sleeve".

I'd have to agree with camaro hunter on this one. Spiffy little engines too =P

Actualy its like a 12 cilinder.
Realy, because 1 rotor has 3 sides(chamders). Thus for a 2 rotor engine there is 6 power strokes per revolution of the crank. But in a regular engine(4 stroke) there is only 1 power stroke per 2 revolutions. Thus a V12 would produce 12 power stroke in 2 revolutions, and so would a 2 rotor rotary.

PS Did a comfuse you yet

Camaro_hunter_d

LOL no, but they ony have 2 plugs per sleeve, so there goes that arguement. LOL I can see how you came up with that though. Though if memory serves me right perrevolution the rotary has 4 power strokes? 1(LOBE) is always drawing in air/fuel, 1(LOBE) is always spitting out exhaust and the other is firing. I think thats how they are fired.

TechSmurf

lol.. someone doesn't understand how rotary engines work.. the crank and rotor rotate at different speeds. Only one power stroke per crankshaft rotation per rotor (but at the same time it *is* also performing intake and exhaust functions. Each crankshaft rotation is only 1/3 rotor rotation. Don't believe me? Look it up on howstuffworks.com

the reason I say they are like a 4 cyl motor is because yes even though they have 3 faces on the rotor, and 2 rotors as techsmurf said the rotor and the e-shaft move at different speeds. the eccentric shaft (crankshaft for you piston people) will rotate 3 times for every time the rotor will do one revolution.
so in thinking this way you get only one combustion each time the e-shaft rotates. you have 2 rotors so you are now at 2 combustion per rotation of the e-shaft.

A 4 cyl motor will not fire all it's cyl on one rotation of the crank either. It only will fire 2 of them. the same amount as my little rotary motor does.

Now if the rotor and e-shaft moved at the same speed then yes I would have something for the most part like a 6 cyl, but since they move at different speeds well it kinda changes that.

And yes even though I have 2 plugs per rotor housing the reason they are there is due to the large combustion area. This way you get a more even combustion process also it helps to reduce emissions by inducing a cleaner and full burn.


So are you going to try to carry on anymore attacks against me?
You know I was not trying to start a little battle of who is better here, or who knows more about cars but if this is the childish thing you are going to resort to then so be it. Though next time I would say to choose something you know a little more about before you try to do this.

Got rotary?
header, intake, ported TB.
soon to have ported intake, lighter rotors,ported motor and a T-66

oops I was a little touchy last night
but yeah you get power "strokes" per turn of the e-shaft. and a little 4 banger gets the same
were your v6 motors will have 3 per turn of the crank.

and sorry bout the whole personal attack thing. lots o crap going on right now so kinda lash out

but hey you want to find out more about the rotary yeah go to www.howstuffworks.com they will give the basic idea
the place I go a lot is http://www.rx7club.com/vforums/index.php in the second gen forum.

Camaro_hunter_d

I was not saying that every lobe fires at the same time. I was saying that as 1 lobe is firing the one behind that is taking in air and the one behind that it spuing exhaust. now this goes on contuniuously through the 4 "clinder sections".
And no RX7 this was not an attack.
