OPTIMISED POWER MANAGEMENT
The DX300LC-5 is equipped with a Scania engine. Famous for excellent fuel efficiency, reliability and long service life, it combines exceptional power output and high torque at low revs. XPI (extra-high pressure injection) common-rail fuel injection (2400 bar) is combined with a Variable Geometry turbocharger for faster machine response, even at very low speed.
Selective Catalytic Reduction (SCR) technology – combined with a Diesel Oxidation Catalyst (DOC) – ensures compliance with Stage IV regulations. As there is no need for a particulate filter, there is no need for regeneration.
If the engine is the heart of the excavator, the e-EPOS is its brain – providing a perfectly synchronised communication link between the engine’s ECU (Electronic Control Unit) and the hydraulic system. A CAN (Controller Area Network) system enables a constant flow of information between engine and hydraulic system, so that power is delivered exactly as needed.
EFFICIENT FUEL MANAGEMENT
• Choice between 4 power modes and 4 working modes guarantees optimum performance in all conditions
• SPC (Smart Power Control): reduces engine RPM during low load demand & ensures pump torque control, thus ensuring fuel efficiency and low emissions
• Engine auto-shut-off: shuts down the engine after the machine has been idling for a specified time
• Electronic control of fuel consumption optimises efficiency
• Auto-idle function saves fuel
• Eco guidance in real time: eco gauge provides information about fuel
consumption relative to machine performance in real-time. By trying to keep the right-hand LED bar from rising, the operator can teach himself how to save fuel and work efficiently
• Separate radiator & hydraulic oil cooler assemblies: allows the hydraulically-driven oil cooler’s fan speed to be controlled by the electronics in order to maintain the optimum oil temperature and reduce noise & fuel consumption.
