CONSTRUCTION
The connecting rod sub-assemblies are made of high-strength steel for weight reduction.
Plastic region tightening bolts are used to achieve a light weight.
The width of the connecting rod bearings has been optimized to reduce friction.
The lining surface of the connecting rod bearing is micro-grooved to provide an optimal oil clearance. As a result, cold-engine cranking performance has been improved and engine vibration has been reduced.
