The listed engine specifications are subject to change without notice, engine dimensions and weight are listed in accordance with Kubota's standard specification. The engine series can be produced in different options so the stated specifications may deviate. The photos shown may contain non-standard equipment.
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. An alternative choice of dimensional images for the D722-E4 engine are: WG752-G (petrol engine) and WG752-GL (choice of dual fuel - petrol and LPG).
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 D722-E4 enables a smooth transition from E3 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:
