Features and benefits

The Kubota Super Mini series is represented by compact multi-cylinder water-cooled industrial diesel engines which correspond to the CARB Tier 4 emission class, and the European Stage V regulations. This series of engines has proven to be an excellent choice for various smaller applications up to 18.5 kW. By expanding the bore and increasing the stroke of the piston, the Z602-E4 is the engine with the highest power density in the 2-cylinder configuration. This achieves higher output power at the same external dimensions as the Z482-E4. By using a shallow engine oil tank, it further lowers the height of the engine and achieves smaller dimensions. Kubota's original casting technology enables the production of an engine block, where the flow channels for the coolant are precisely metered, thus enabling higher power density and superior engine durability.

Emissions

The developed E-TVCS (Three Vortex Combustion System) has been improved for cleaner emissions. 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. The Kubota Z602-E4 enables a smooth transition from E2 to E4 emission class without physical changes to the engine itself and power and torque characteristics. Complies with European regulations on the level of exhaust particles: Kubota Stage V logo
