  • The water channel on the cylinder block left side is integrated with the block to allow a more compact engine.
  • The insides of the cylinder bores are coated with a thin iron film and the cylinder liners are eliminated for reducing weight and improving cooling performance.
  • The centers of the cylinder and crankshaft are offset for reducing friction.

  • A shallower water jacket (shallower base) is used around the cylinder bore to reduce heat loss to the coolant and maintain an even liner temperature.
  • Projecting shapes are used on the cylinder liner periphery for improving aluminum adhesion for reducing bore deformation and improving cooling performance by increasing the surface area.
