So here's how it works........
A rotary engine is an internal combustion engine, like the engine in your car, but it works in a completely different way than the conventional piston engine.
In a piston engine, the same volume of space (the cylinder) alternately does four different jobs -- intake, compression, combustion and exhaust. A rotary engine does these same four jobs, but each one happens in its own part of the housing. It's kind of like having a dedicated cylinder for each of the four jobs, with the piston moving continually from one to the next.
The rotary engine (originally conceived and developed by Dr. Felix Wankel) is sometimes called a Wankel engine, or Wankel rotary engine.
In this edition of HowStuffWorks, we'll learn how a rotary engine works. Let's start with the basic principles at work.
The Basics
Like a piston engine, the rotary engine uses the pressure created when a combination of air and fuel is burned. In a piston engine, that pressure is contained in the cylinders and forces pistons to move back and forth. The connecting rods and crankshaft convert the reciprocating motion of the pistons into rotational motion that can be used to power a car.
In a rotary engine, the pressure of combustion is contained in a chamber formed by part of the housing and sealed in by one face of the triangular rotor, which is what the engine uses instead of pistons.
The rotor and housing of a rotary engine from a Mazda RX-7: These parts replace the pistons, cylinders, valves, connecting rods and camshafts found in piston engines.
The rotor follows a path that looks like something you'd create with a Spirograph. This path keeps each of the three peaks of the rotor in contact with the housing, creating three separate volumes of gas. As the rotor moves around the chamber, each of the three volumes of gas alternatively expands and contracts. It is this expansion and contraction that draws air and fuel into the engine, compresses it and makes useful power as the gases expand and then expels the exhaust.
In the next section, we'll take a look inside a rotary engine and check out the parts.
Now everyone can know !

how thingsworks is a very good site...I have seen it before and who ever came up with this site had to much time on thier hands...
Doing a quick glance I saw it say that most rotary engines have 2 spark plugs...Well most 2 rotor engines..has 4 spark plugs...
2 trailing 2 leading..
trailing 1 trailing 2
leading 1 leading 2

Why do some rotaries look small as hell and some big? Fuel injection models just look bigger because of all the shit compared to carb ones?
