<p>Doosan DX490LC-3 excavator</p>

The Doosan DX490LC-3 and DX530LC-3 excavators replace the DX480 and DX520 respectively, have been designed with improvements that include increased engine horsepower and lift capacity, improved bucket digging force, enhanced cooling capabilities, and better fuel efficiency, according to the company. The machines can be used in road building, site development, oil and gas pipeline development, and other construction applications.

The DX490LC-3 and DX530LC-3 excavators are powered by a 6-cylinder 389-hp water-cooled diesel engine that has been optimized for use with a cooled exhaust gas recirculation (CEGR) system, a diesel oxidation catalyst (DOC), and a diesel particulate filter (DPF). Engines with this configuration are optimized to reduce nitrogen oxides (NOX) and after-treatment is needed to reduce particulate matter in compliance with iT4 emission regulations. The turbocharged engine features a high-pressure common-rail design with direct fuel injection, electronic control, and four valves per cylinder.
