Hybridization is frequently applied in order to increase the energy efficiency of off-road and construction machinery. One such novel energy saving method was proposed for working hydraulics, based on an established zonal concept for airplanes. The introduced method supplied the power on demand to the actuators, utilising direct-driven hydraulics in machinery. However, component selection plays a significant role in order to achieve high efficiency. Therefore, the primary goal is to evaluate the energy efficiency of selected components for the front hoe of the micro excavator under the digging and levelling cycles. The efficiency of the zonal hydraulic preselected components was evaluated utilising a developed Matlab/Simulink model and energy efficiency maps.
