(1) Small-sized and light-weight engine
• Since no liners are used in the engine block, the distance between the cylinders is reduced by the thickness of the liners, thus the overall length of the engine is reduced.
• The stroke bore ratio is as large as 115 mm/95 mm. The overall height of the engine is reduced, however, by reducing the distance between the big end center and small end center of the connecting rod.
• The heads of the cylinder head and cylinder block are thinned and light-weighted but their strength is maintained.
• Each part is designed economically for weight reduction by applying reliability analysis technologies.
(2) High-performance engine
• Combustion efficiency is improved, exhaust gas is made clean, emission performance is improved, and noise is reduced by designing the air intake port having less air suction resistance and employing the swirl chamber.
• Friction loss horsepower is reduced by reducing the weight of the main moving parts and setting the capacity of the auxiliary devices (water pump and oil pump) properly.
• The weight, noise, and vibration are reduced by adjusting the clearance between each piston and cylinder properly.
(3) Other items
• Glow plugs which consume less electric power are employed for the starting aid to reduce the load on the battery.
• Noise is reduced by improving the shape of the piston and applying float mounting of the head cover.
• Reliability and durability are heightened by the developing technology based on experience
