Purpose, Function

Connecting rod

•  The connecting rod transmits the reciprocating movement of the piston to the crankshaft by engaging the piston pin and crank pin.

Connecting rod bearing

•  The connecting rod bearing forms an oil film on the outer surface of the crank pin to prevent wear due to sliding.

Construction

Connecting rod

•  The connecting rod is installed between the piston pin and crank pin.

•  High-strength, forged carbon steel has been adopted for weight reduction.

•  A cracking method for breaking off and separating the connecting rod from the connecting rod cap has been adopted for improved accuracy.

•  Weight has been reduced by optimizing the shape from the I shaft to the large end.

•  Reciprocating inertial weight, including the piston, has been reduced with the use of a full-float type for the connection with the piston and further tapering of the small end shape.

•  With the adoption of the plastic region tightening method for the connecting rod bolt, the stability of the axial force has been improved.
