SIDE HOUSING OUTLINE

• With the adoption of a side intake and exhaust port system.

• Intake and exhaust port overlap has been eliminated on the side intake and exhaust port system by way of independently set intake and exhaust port size configurations. As a result, stable combustion is achieved due to the combustion gas not flowing into the intake process.

• With 2 exhaust ports per rotor, open-timing on the exhaust ports can be retarded while maintaining sufficient port size. Therefore, the expansion process period has been increased, improving heat efficiency and resulting in high engine output with reduced fuel consumption.

• By retarding the close-timing of the intake ports, intake air volume has been increased for higher engine output.

• With the adoption of side exhaust ports, non-combusted gas, which used to be swept by the apex seals, is sent to the next combustion process for re-combustion, resulting in reduced exhaust from non-combusted gas.
