PERFORMANCE CURVES
FEATURES and BENEFITS
Emissions
The Kubota Super Mini Series features compact multi-cylinder
liquid cooled industrial diesel engines which comply with EPA /
CARB Tier 4 emissions level.
Durable Power
The D902 engine delivers the highest output among the Kubota
Super Mini Series engines.
By expanding the bore and stroke, Kubota has increased engine
displacement while maintaining its compact size. The use of an
extended shallow oil pan keeps the engine height lower than that
of the D722, providing a compact engine package.
The cooling water passages between the cylinder bores features
Kubota’s original casting technology as a countermeasure against
the heat load caused by high power density, providing both superior
endurance and reliable engine performance.
This engine offers a seamless transition from EPA Tier 2 to EPA
Tier 4 by maintaining the same level of performance and physical
characteristics.
Alternative fuel engines WG972-G (gasoline) and WG972-GL
(dual fuel: gasoline / LPG) are available with the same footprint
as the D902 engine.
Clean and Quiet Power
Kubota’s original E-TVCS (Three Vortex Combustion System) has
been improved. The piston recess has been optimized to achieve
lower particulate matter (PM) levels at an extremely small size.
The half-float valve cover and MoS2-coated pistons reduce noise
levels and decrease vibrations transmitted from the valve area,
providing enhanced noise reduction.
