ENGINE UNIT


  1. CONSTRUCTION


    1. The pistons are made of aluminum alloy to allow them to be compact and lightweight.

    2. The piston head portion uses a taper squish shape to achieve fuel combustion efficiency.

    3. Full floating type piston pins are used.

    4. A hard anodizing treatment is applied to the top piston ring groove to ensure abrasion resistance.

    5. The piston skirt is coated with resin to reduce friction losses.

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

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

    8. A No. 1 compression ring with an inside bevel shape is used to reduce blow-by gas.

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