Doosan’s DX300LC-3 and DX340LC-3 excavators get the Korean maker’s DL08K common rail six-cylinder turbocharged diesel engine meeting stage IIIB emission regulations thanks to EGR and DPF technologies.
At 159kW, the DL08K engine in the DX300LC-3 excavator delivers two per cent more power at a lower engine speed of 1,800rpm when compared to the existing stage IIIA version.
It is a similar story with the 210kW DX340LC-3 – the fettled excavator brings operators a seven per cent increase in power, also at lower engine revs.
Doosan said factory tests show a 5-10per cent reduction in fuel consumption.
And a new ECO gauge on the control panel monitors fuel rate and actual engine-percent load. Doosan has also added two new operating modes: Power Plus and Lifting, to further improve controllability and efficiency.
