  4. Piston


    1. The piston is made of aluminum alloy.

    2. In conjunction with the adoption of direct injection, the piston provided with combustion chamber is used.

    3. A cooling channel is provided to realize excellent piston performance.

    4. The top ring groove uses a Ni-resist cast iron ring carrier to improve wear resistance.

    5. The piston skirt is coated with resin to reduce friction loss and improve initial seizure resistance.

    6. A PVD (Physical Vapor Deposition) coating has been applied to the surface of the No. 1 compression ring, to improve its wear resistance.*

  5. Connecting Rod


    1. The connecting rods and caps are made of high-strength material to ensure the proper strength.

    2. Knock pins are used at the mating surfaces of the bearing caps of the connecting rod to minimize the shifting of the bearing caps during assembly.

    3. Nutless type plastic region tightening bolts are used.

    4. The connecting rod bearings are reduced in width to reduce friction.

  6. Crankshaft


    1. A crankshaft made of forged steel, which excels in rigidity and wear resistance, is used.

    2. The crankshaft has 5 journals and 7 balance weights.

    3. All pins and journal fillets are IH (Induction Hardening)-finished to maintain adequate strength.

    4. An aluminum bearing is used for the crankshaft bearings.
