The excavator is powered by the Stage V version of the Perkins 2506J diesel engine, providing output of 403 kW (548 HP).
The relevant Stage V technology integrated into the engine includes exhaust gas recirculation, selective catalyst reduction, diesel oxidation catalyst and diesel particulate filter (DPF) after-treatment technologies.
The DX800LC-7's Virtual Bleed Off (VBO) hydraulic system (D-ECOPOWER+) provides a hydraulic flow of 1008 l/min and a high system pressure of 343 bar, said Doosan.
The D-ECOPOWER+ system utilises an electronic pressure-controlled pump within a closed centre hydraulic system to optimise productivity and fuel consumption.
The excavator uses a 2-spool Boom Down Regeneration system, which also reduces fuel consumption. The 2-spool hydraulic system for the bucket cylinder also increases hydraulic flow and the working speed of the bucket.
