ROTOR CONSTRUCTION

BHE011011910T02

• The special cast iron rotors have a hollow interior structure.

• Reduction in rotor weight has been achieved by reducing the thickness of the ribs in the rotor interior.

• The outer surfaces of the rotor include rotor recesses that serve as the combustion chambers. (Bathtub shape)

• A rotor bearing has been installed to the interior wall of the central axial area because the wall rubs against the eccentric shaft.

• Flank cuts are located at the corners of the rotor to delay exhaust closing timing by approx. 15 degrees, improving exhaust efficiency.
