ENGINE UNIT


  1. CONSTRUCTION


    1. The pistons are made of aluminum alloy.

    2. The tops of the pistons utilize a taper squish shape to achieve fuel combustion efficiency.

    3. The piston skirts are coated with resin to reduce friction losses.

    4. The groove of the No. 1 compression ring is coated with alumite to ensure abrasion resistance.

    5. Low-tension piston rings are used to reduce friction and achieve excellent fuel economy.

    6. Narrow-width piston rings are used to reduce weight and friction.

    7. 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.
