DOOSAN ENGINE (DL08)
At the heart of the hydraulic excavator is the new “Common Rail” DOOSAN DL08 engine. It is combined with the new e-EPOS electronic control system, for optimum power and fuel saving. The new engine produces 256 hp(191 kw/260 PS) at 1,900 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.
HYDRAULIC PUMP
The Main pump has a capacity of 2 x 265 l/min reducing cycle time while a high capacity gear pump improves pilot line efficiency
SWING DRIVE
Shocks during rotation are minimized, while increased torque is available to ensure rapid cycles.
EXCAVATOR CONTROL NEW E-EPOS SYSTEM (ELECTRONIC POWER OPTIMIZING SYSTEM)
The brains of the hydraulic excavator, the e-EPOS, have been improved and now can electronically link to the engines ECU (Electronic Control Unit), through a CAN (Controller Area Network) communication link, enabling a continuous exchange of information between the engine and the hydraulic system. These units are now perfectly synchronised. The advantages of the new e-EPOS impacts at several levels, Ease of operation and user-friendliness:
- The availability of a power mode and a normal operating mode guarantee maximum efficiency under all conditions.
- Electronic control of fuel consumption optimizes efficiency.
- The automatic deceleration mode enables fuel saving.
- Regulation and precise control of the flow rate required by the equipment are available as standard.
- A self-diagnosis function enables technical problems to be resolved quickly and efficiently.
- An operational memory provides a graphic display of the status of the machine.
- Maintenance and oil change intervals can be displayed.
In your profession, you need equipment you can depend on. At Doosan, we use highly specialised design and analysis tools to make sure our machines are as robust and durable as can be. Our materials and structures undergo stringent testing for strength and resilience under the most extreme conditions. And we continually manufacture the most durable machines to ensure lower cost of ownership.

INTEGRATED TRACK SPRING AND IDLER
The track spring and the idler have been joined directly to achieve high durability and improved maintenance convenience.
RELIEF CUTOFF
The pump continues to supply flow even when the maximum pressure on the system is reached due to severe working environments and large workloads. Relief cutoff technology of DX225LCA prevents transfer of unnecessary flow to maintain powerful working level at the maximum value while reducing consumption of fuel.
OPTIMIZED LEVER CONTROL & AUTO IDLE
When operator takes a break and leaves the control joystick fixed, both of the engine and the pump are kept in standby mode and prevents unnecessary fuel consumption.
PUMP MATCHING TECHNOLOGY
Engine & pump matching, the new technology of Doosan, fully resolves problems; low respones time of the system, unnecessary fuel consumption. Matching response time between pump and engine efficiently reduces unnecessary fuel consumption as well as exhaust fumes.
More space, better visibility, air conditioning with climate control, very comfortable seat. These are the elements that ensure the operator can work in the beest possible conditions. Furthermore, a new, user-friendly colour 7" TFT LCD monitor panel gives full access to machine settings and maintenance data allowing you to work safely and confidently with an accurate overview of all conditions

Doosan provides fast and precise worldwide delivery of genuine Doosan parts through its global PDC (parts distribution center) network.
The global network of the GPDC (Global Parts Distribution Center) maximizes its supply rate by making sure that each center is stockpiled with all the critical parts required for businesses in its area. The network also minimizes the time and costs required for parts delivery by positioning PDCs close to major markets around the world. Doosan PDCs communicate with customers in their time zone, informing them that they are open for operation, and deliver parts to them as early as possible.
PDCs had been set up as shown below, including Mother PDC in Ansan, Korea. The seven other PDCs include one in China (Yantai), one in the USA (Chicago), one in Brazil (Campinas), two in Europe (Germany and the UK), one in the Middle East (Dubai), and one in Asia (Singapore).
