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. An anodic oxide coating is applied to the No. 1 compression 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 blowby gas.

    9. The sliding surface of the No. 2 compression ring is chrome plated for improved wear resistance.

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