Engines Powertrain

• The above is a description for only one chamber; the other two operate in exactly the

same way. As a result of these actions by only one chamber, the rotor makes one

rotation (during which the eccentric shaft turns three times), resulting in an intake of the

gas mixture followed by compression, combustion and exhaust. Also, because there are

three chambers on one rotor, there are three combustion (output) cycles for each

revolution of the rotor. In other words, one combustion cycle takes place for each

revolution of the eccentric shaft.

• Concerning gas exchange, the cycles of the rotary engine are the same as those of a

four-stroke reciprocating engine, but combustion cycles per revolution of the output shaft

are the same as on a two-stroke reciprocating engine. Consequently, the rotary engine is

a special type of engine that neither falls into the four-stroke nor two-stroke category.
