  1. CONSTRUCTION


    1. A piston provided with a combustion chamber is used.

    2. The piston is made of aluminum-silicon alloy.

    3. A cooling channel has been provided to reduce the piston temperature and achieve high reliability.

    4. The top ring groove uses a cast-in ring carrier to improve wear resistance.

    5. A graphite (graphal procedure) coating is applied to the piston skirt portion in order to achieve friction loss reduction.

    6. The top inner edge of the No. 1 compression ring is chamfered. The outer surface of the No. 1 compression ring is polished and slightly crowned. The No. 1 compression ring has a chrome ceramic layer for low wear.

    7. The No. 2 compression ring has a sharp lower edge which gives the ring an oil-stripping effect.

    8. The running surface of the oil ring is chromium-coated.
