Friction Losses Between Piston Ring Liner Assembly

2GR-FKS Engine

The piston skirt is coated with resin to reduce friction losses. The groove of the top ring is coated with alumite to ensure abrasion resistance. By increasing the machining precision of the cylinder bore diameter in the cylinder block sub-assembly, only one size piston is required. Text in Illustration *1 Front Mark — — *a Taper Squish ...
