KUBOTA HORIZONTAL WATER-COOLED DIESEL ENGINE RKIERIKND Series Displacement. 305 cc~ 1,181 cc Maximum Output. 5.0 HP-25.0 HP A Wide Range of Diesel Engines to Satisfy Any Need, Anywhere . RK80-1, 95-1, 105-2, 125-2, ER (KND)1900D1, 2200D1, 2500D1 "Direct-Injection System Save 20% on Your Monthly Fuel Bill with a Direct-Injection Engine Many of Kubota's diesel engines incorporate an advanced direct injection combustion system that can reduce fuel consumption by as much as 20% compared with conventional swirl combustion and precombustion chamber systems . This highly-efficient direct-injection combustion system places the combustion chamber in a cavity in "TVCS System TVCS for Steady, Efficient Operation Kubota's TVCS (Three-Vortex Combustion System) is a revolutionary system that creates three vortexes within the combustion chamber in order to produce an air/fuel mixture with a uniform spray and an optimum average particle size. This ideal air/fuel mixture, in turn, ensures complete " Comes with a Built-in Balancer the top of the piston itself in order to minimize power-robbing gas leakage and to prevent heat loss. It also has a swirl-type design inlet ports for more efficient mixing of air and fuel. Add it all up, and you have a highly-efficient diesel engine with powerful performance and superior fuel economy . R K50, 60, 70 044 combustion for greater power output and more steady operation . As a result, Kubota's compact, lightweight engines are just as powerful and efficient as much larger conventional engines . R K105-2 7 125-2 Both noise and vibration, caused by the piston's to-and-fro movement, are suppressed with the standard built-in balancer. RK50,60,70,80-1,95-1,105-2,125-2 " Increased Lighting Lighting is increased from 6V-25W to 12V-45W. Increased lighting makes it easy to see as well as adds safety to working at night . R K80-1,95-1 9 105-29125-2 " New Handle-Start Position The new handle-start position is in the front of the engine. This makes it much easier to start up the engine. 'All engines on this catalog are built in Kubota's quality assured, ISO 9002 certified engine plant.
