Reduced: Ecology & Economy

The document discusses a newly developed Komatsu excavator that significantly reduces emissions and fuel consumption compared to previous models. It achieves this through an efficient engine and hydraulic system that are electronically controlled. Fuel consumption is reduced by 7% versus the previous PC200-8 model under typical work conditions.
