FEATURES and BENEFITS

Emissions

Kubota Super Mini Series, the most compact multicylinder 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.

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.

Durable Power

The Kubota Super Mini Series has been chosen as a power source for a variety of applications since it was first launched 25 years ago. It has become the benchmark in the compact diesel engine market. The D722 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.
