Emissions

Kubota Super Mini Series, the most compact multi-cylinder liquid cooled industrial diesel engines,

complies with EPA Tier 4 emissions regulations.

These are the most stringent emissions regulations

in the world in this class.

Durable Power 

The Kubota Super Mini Series has been chosen as a

power source for a variety of applications since itwas first launched 25 years ago. It has become the

benchmark in the compact diesel engine market.

The D722 engine offers a seamless transition fromTier 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 CombustionSystem) has been improved. The combustion

chamber was optimized to achieve a 50% lower

particulate matter (PM) level in such a small size

range.

Gross Intermittent SAE J1995
