rotary engines

hey....im still trying to figure out how rotary engines work. i now that they have no pistions (right?) and on large triangular cam like thing in them center of the engine

could someone explain this to me.....cuz i have a slight idea as to how the work, but its pretty vauge....

well, I am not quite sure myself. But the numbers it puts out is astounding!

thats true for sure...cuz they have what? 1.3 L engines??

and one more question, what the difference between 2, 3, and 4 rotor engines?? is that the amount of the triangular cam like things the engine has??

so no one knows how their rx7 engines work?? seriouosly!?

something like that i believe. i cant really explain it though. dont know how much that really helps.

so then do rotary engines not have any valves then??
and is that why they redline at like, 14,000 or more?? because they have no pistons but instead just giant rotors??

there....i did the work for myself.....

that really helped out a lot. thats a great website.

Here is a much more indepth look at how the rotary engine works:

And for animations, there are a ton over here:

It is simple, it is simply a variable geometry, variable displacement, moving combustion chamber. (like a 2 cycle on steroids) think of it as 3 combustion chambers on each rotor (each flat face) and instead of the piston moving like in a piston car the rotor moving changes the size of the combustion chamber. LOL Please forgive me, I work on aircraft engines for a living.

ok get ready to read...
a rotary engine does not have any pistons or reciprocating parts, so theres no head. a normal RX7 12A or 13B engine has 2 triangular rotors that dont even touch the housibgs. in sequence, it is front housing, center housing, rear, front, center, and then rear again. the engine is usually ported for easier entrance and exit of a/f mixture. it is only 2 little ports like 2 little holes that let the a/f mixture enter and exit. it is still four-stroke engine but the timing of spark plugs are different. there is the leading and trailing spark plug, 2 per rotor. the leading plug is actually the last one to touch the a/f mixture but the first to ignite. one spark plug ignites twice,i think the trailing i dont remember, but it is done to improve efficiency of a perfect combustion. rotary engines also smaller and lighter than normal I-4 engines, so that is why the RX8 is able to have a perfect 50/50 weight distribution. the main disadvantage of the rotary engine, though, is that it heats up quicker and that it is harder to maintain emissions legality...
there is more but now i got tired of writing...lol
