Kubota OC Series Engines

Ranging in output from 6 to 9.4 net intermittent horsepower at 3600 rpm, the Kubota OC Series are single cylinder, 4-cycle oil-cooled diesel engines and comply with current EPA Tier 4 emissions regulations. These unique engines have the light weight and compact features of an air-cooled engine together with the low noise, durability and clean exhaust emission of a water-cooled diesel engine. Equipped with Kubota's ACTV (Advanced Cooling Three Vortex) system, the cylinder block is air-cooled, while the combustion area of the cylinder head is oil-cooled.
