Powered by a 176-horsepower, 6-cylinder water cooled diesel engine that uses a cooled exhaust gas recirculation system, diesel oxidation catalyst and diesel particulate filter, the DX190W-3 delivers increased power and performance. The turbocharged engine has a high pressure common-rail design with direct fuel injection, electronic control and four valves per cylinder.
The excavator features the Electronic Power Optimizing System which provides power and fuel efficiency through four work modes (digger, breaker, shear and lifting), an auto-idle and machine diagnostics. A new Power + mode delivers faster speeds in heavy duty work. The excavator’s new electronic fan clutch provides cooling system improvements while reducing fuel consumption and noise levels.
Doosan has improved the ROPS cabin by adding a seat height lever and tilting function for the seat cushion, boosting operator comfort. The cabin mounting mechanism now has a thickened dampening plate and internal coil spring that reduce cabin vibration by 20 percent.
Additional improvements include increased door space (by 1.8 inches), increased cabin size (by 6.1 percent) and a reduced joystick angle (from 25 to 19 degrees).
Options include an Intelligent Floating Boom that enables the boom to move freely up and down without hydraulic flow, and an air compressor that blows out the cab or filters in dusty locations.
