...directly into rotary motion.* Yet unlike other rotaries, it retains many of the acknowledged advantages of conventional internal-combustion engines. In standard auto engines, for example, the reciprocating actions of cylindrical pistons successively suck in a mixture of gasoline and air, compress it, turn a crankshaft after an electric spark touches off the explosive vapors, then expel the burned fuel residues. In rotary engines like the Wankel, the same effect is achieved not by reciprocating pistons but by a turning rotor. As it revolves inside a specially shaped chamber, the rotor is able to perform all the basic strokes...
...into the cylinder of the power piston (2). Continuing its rotation, the power piston compresses the air even more (3). As the piston's cylinder moves past the fuel injector, the compressed air is mixed with a spray of gasoline (4). Then, as the cylinder edges by the spark plug, the fuel-air mixture is ignited (1). Pressed by the expanding gases, the piston begins the equivalent of the power stroke. All the while, it continues its rotary motion (2, 3 and 4). Finally, as the power piston's cylinder passes another opening in the engine casing...
