Doosan Provides DX350LC with Interim Tier 4 Updates

The Doosan DX350LC excavator is more than just interim Tier 4 compliant. Improvements span from more engine horsepower (281 hp) and torque to a turbocharger, upgraded cooling system and new hydraulic system.

The 7.6 l DL08K turbocharged diesel engine has been optimized for use with cooled exhaust gas recirculation (CEGR) system, diesel oxidation catalyst (DOC) and diesel particulate filter (DPF). It features a common rail design with direct fuel injection, electronic control and four valves per cylinder.

Cooling system upgrades include two variable-speed hydraulic fans. This allows the engine and oil cooling systems to be controlled independently, improving fuel efficiency and provides a quieter operator environment.
