With a maximum output of 18.5 kW at 3,600 rpm and maximum torque of 56.1 Nm, the D902-E4B is ideal for heavy-duty industrial applications where compact size and high performance are essential. Thanks to its enlarged displacement and clever construction, the engine maintains the same compact footprint as the smaller D722 series.

Kubota TVCS (Three Vortex Combustion System) technology ensures efficient combustion, low emissions and low fuel consumption. In addition, MoS2-coated pistons and an optimized design contribute to reduced vibration and quieter operation.
