BALANCE WEIGHT, COUNTERWEIGHT (AT), FLYWHEEL (MT) CONSTRUCTION
CHU011011901S04
•
A balance weight and a counterweight (AT) have been installed to prevent dynamic unbalance.
•
For MT, a weight has been added to perimeter of the flywheel to obtain the same balancing effect as the
counterweight on AT.
•
The weight of balance weights for both MT and AT changes in accordance with the difference in rotation-
related mass of the transmission that is employed.

Lightweight rotors have been adopted that correspond to the high-speed rotation for improved engine
response.

ROTOR CONSTRUCTION
CHU011011910S02
•
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.
