  1. CONSTRUCTION


    1. Cylinder Head


      1. The cylinder head is made of aluminum alloy.

      2. The intake manifold is integrated the cylinder head to realize compact design.

      3. The injector is located near the center of the combustion chamber to promote the mixture of fuel and air.

      4. A water jacket consists of the 2-stage construction to realize excellent cooling performance.

    2. Cylinder Block


      1. The cylinder block is made of aluminum die-cast.

      2. A compact block has been achieved by producing the thin cast-iron liners and cylinder block as a unit. Do not bore the block with this liner.

      3. The liners are the spiny-type, which have been manufactured so that their casting exterior forms a large irregular surface in order to enhance the adhesion between the liners and the aluminum cylinder block. The enhanced adhesion helps improve heat dissipation, resulting in a lower overall temperature and heat deformation of the cylinder bores.

      4. Cylinder block water jacket spacers are used in the water jackets of the cylinder block sub-assembly. They suppress the water flow in the center of the water jackets, guide the coolant above and below the cylinder bores, and ensure uniform temperature distribution. As a result, the viscosity of the engine oil that acts as a lubricant between the bore walls and the pistons can be lowered, thus reducing friction.

    4. Piston


      1. The pistons are made of aluminum alloy.

      2. The combustion chamber is provided on the piston for direct injection.

      3. A cooling channel is provided to realize excellent piston cooling performance.

      4. A cast iron ring carrier is used to realize excellent wear resistance.

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

      6. Full floating type piston pins are used.
