Basic principles of the rotary engine
|
The rotary engine is very powerful for its size. It uses a rotor instead of pistons. It is an internal combustion engine so it uses the 5 events: Intake, Compression, Ignition, Power , Exhaust.
|
Basic components of the rotary engine
|
The rotor is attached to an eccentric shaft. During combustion, a gear in the rotor makes the rotor walk around a stationary gear. This combines with the eccentric shaft to give the rotor planetary motion.
|
Rotary engine cycle
|
Inlet and exhaust ports are covered and uncovered by the lobes of the turning rotor. As the rotor turns, the working chamber changes size. After intake, it becomes smaller, and compresses the air-fuel mixture.
|
Rotary/piston engine comparison
|
For each complete rotation of the rotor, there are 3 power pulses, one for each chamber. At any one time, each chamber is in a different phase.
|
Rotary engine power pulses
|
The eccentric shaft does one revolution for each power phase. That means three revolutions for each rotor rotation. So the eccentric shaft turns at three times the speed of the rotor.

The Renesis engine is a further development of the "Wankel" rotary engine. |
