Kubota Super Mini Series – the most compact multi-cylinder liquid cooled industrial engines – complies with EPA Tier 4 emissions regulations. These are the most stringent emissions regulations in the world in this class.
The D902 engine delivers the highest output within the Kubota Super Mini Series engines. By expanding the bore and stroke, Kubota increased engine displacement, while maintaining the same footprint as the D722 engine. By adopting an extended shallow oil pan, the engine height is lower than the D722 engine, providing a compact engine package.
The cooling water passages between the cylinder bores, using Kubota’s original casting technology as a countermeasure against heat load of high power density, provides both superior endurance and reliable engine characteristics.
This engine offers a seamless transition from Tier 2 to Tier 4 by totally maintaining the same performance and physical characteristics of the previous Tier 2 engines.
Alternative fuel engines, WG752 (Gasoline) and DF752 (Dual Fuel: Gasoline/LPG) are available with the same footprint as the D722 engine.
Clean and Quiet Power
Kubota’s original E-TVCS (Three Vortex Combustion System) has been improved. The combustion chamber was optimized to achieve a 50 % lower particulate matter (PM) level in such a small size range.
The half-float valve cover and MoS2 coated pistons reduce noise levels and provide reduced transmitted vibration from the valve area for better noise characteristics.
A great variety of additional accessories is available.
- RATED POWER 16.1 KW / 3200 RPM
- CYLINDERS 3
