This is incorporated KU BOTA's forem ost technologies. With KU BOT A's spheri cal combustion chamber, well-known Bosch K type i nj ecti on pu m p and the well-balanced designs, they give greater power, low fuel consumption, little vibration and quiet operation. 0107F010 M.1-1

B1550B1 750·B2150·B1550HST·B1750HSTB2150HST WSM,60354-0 M.l ENGINE [1] ENGINE BODY (1) Cylinder Block 0107FOll (2) Cylinder Head @ 0107F012 ® ® 0011F013 (1) Combustion Chamber (2) Suction (3) Exhaust ® (4) Nozzle Assembly (5) Glow Plug (6) Cylinder Head The engine has a high durability tunnel-type cylinder in which the crankshaft bearing part is constructed in a body. Furthermore, dry-type cylinder liners, being pressure-fitted into cylinders, allow effective cooling, less distortion, and greater wear- resistance. The noise level is reduced to a minimum because each cylinder has its own chamber. The cross·flow type inlet/exhaust ports in this engine have their openings at both sides of the cylinder head. Because overlaps of inlet/exhaust ports are smaller than in ports of other types which have openings on one side, the suction air can be protected from being heated and expanded by heated exhaust air. The cool, high density suction air has high volume efficiency and raises the power of the engine. Furthermore, distortion of the cylinder head by heated exhaust air is reduced because suction ports are arranged alternately. The combustion chamber is of KUBOTA's exclusive spherical combustion chamber type. Suction air is whirled to be mixed effectively with fuel, prompting combustion and reducing fuel consumption. In the combustion chamber are installed throttle type injection nozzle and rapid heating sheathed type glow plug. This glow plug assures easier than ever engine starts even at -15°( (5°F). M.1-2
