SUMMARY
The first thing you notice about rotary engines are their incredibly compact dimensions. A basic 13B (1.3 liter) engine is approximately the size of a beer keg and can be lifted by one fit person. At the same time, it has a volumetric capacity twice that of a conventional piston engine of identical rated displacement. How is this possible? The secret is in the packaging. Each rotor section (rotor and housing) form three working chambers, which work simultaneously to move its entire rated displacement on each turn of the eccentric shaft.

Good job scorpion6.
Just a few changes to point out for the "Rx8" motor. The well defined exhaust ports in the picture you posted is not bored in the side of the rotor housing like earlier 13b motors. The machining pattern is still there, it's just not bored out. The location and size of the port allowed a heat proned engine to extract the exhaust heat
The exhaust is now routed through the side housing vary similar to the intake tract. This change makes the chance of seeing a turbocharged model unlikely.
