Presentation transcript:

Wankel or Rotary engine No Piston. Rotor that spins in an oval chamber (shaped like a flat figure 8) by burning fuel. Rotor has three lobes. Rotor rotates in an eccentric pattern. The lobes remain in contact with the oval housing, creating a tight seal.

Intake stroke The fuel/air mixture is drawn in the intake port during this phase of the rotation.

Compression stroke The mixture is compressed here.

Power stroke Spark plug fires and the mixture burns here, driving the rotor around.

Exhaust stroke And the exhaust is expelled here.

4 - Strokes All the four strokes – intake, compression, power and exhaust – are going on at the same time around the rotor.
