Daewoo Doosan Dx420lc-3 The key phrase used during the development of the DX420LC was “giving optimum value to the end user”. This translates, in concrete terms, into:
• Increased production and improved fuel economy thanks to electronic
optimization of the hydraulic system and the new generation Doosan engine
(stage IIIa).
• Improved ergonomics, increased comfort and excellent all round visibility
ensuring a safe and pleasant working environment.
• Improved reliability through the use of high performance materials combined
with new methods of structural stress analysis have lead to increased
component life expectancy, thus reducing running costs.

Performance
The performance of the Daewoo Doosan DX420LC has a direct effect on its productivity. Its new “Common Rail” engine
and new e-EPOS controlled hydraulic system have combined to create an unbeatable hydraulic excavator,
with a cost/performance ratio that makes the DX420LC even more appealing.
At the heart of the hydraulic excavator is the new “Common Rail” Doosan DV11 engine. It is combined with the new e-EPOS electronic control system, for optimum power and fuel saving.
The new engine produces 293 hp (218 kW/297 PS) at only 1.800 rpm, and more torque, due to its careful design combined with the use of common rail injection and 4 valves per cylinder. These features help optimize combustion and minimize pollution through reduced Nox & particulate emissions.
Increased torque allows efficient use of the power of the hydraulic system.
• Faster working cycles increase productivity.
• Increased torque means the excavator is able to move more easily.
• Energy efficiency reduces fuel consumption.
