Each rotor has three combustion chambers, a person for each side, and is housed between a pair of plates to produce a closed chamber. Rotary-design engines are available a single rotor form into the Le Mans-winning four-rotor engine.
This brought massive ability gains for the rotary engine and authorized the reduced displacement RX-7 to flourish in motorsport in opposition to standard piston engines.
Since the rotor turns, the combination is compressed because the geometry Within the chamber modifications. After the combination reaches within the two o’clock position, two spark plugs fire.
