ENGINE UNIT


  1. CONSTRUCTION


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

    2. The piston is made of aluminum alloy.

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

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

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

    6. A resin coating is applied to the piston skirt portion, to achieve reduction of friction loss.
