Fuel efficient hybrid excavator

Energy Harvesting: Off-Grid MicroW to MegaW 2017
Komatsu Europe International has introduced the new HB365LC-3, a high technology and environmentally sustainable 36 tonnes hydraulic hybrid excavator. Compared to a standard PC360LC-11 excavator, the new Komatsu Hybrid excavator was designed to provide 20% fuel savings to customers and data shows that Komatsu has reached this target.
 
Since 2008, when Komatsu commercialized the first hybrid construction equipment in the history of the industry, a total of 10,000,000 hours of operation have been registered by excavators benefiting from Komatsu's proven hybrid technology, which is today at work on over 3,500 units worldwide. The new HB365LC-3 hybrid excavator features an EU Stage IV engine and ultra-low noise levels, and it further reinforces Komatsu's strong commitment towards a substantial reduction of the environmental impact of earthmoving machines.
 
Cutting-edge technology
The HB365LC-3 has the same SAA6D114E-6 engine (202 kW / 271 HP) as the PC360LC-11, with up to 53kW extra electric power supplied by the revolutionary Komatsu Hybrid system. The kinetic energy generated during the swing-braking phase is converted to electricity, which is sent through an inverter and captured by the Komatsu Ultra Capacitor. When accelerating under workload conditions the captured energy is discharged quickly for upper structure rotation and to assist the engine as commanded by the hybrid controller. The reserve power stored by the hybrid technology represents additional horsepower that is available to maximize machine performance by supporting the engine, or is used for swing power.
 
Solid-State and Polymer Batteries 2017-2027
All machine components and the EU Stage IV engine are optimally controlled to match the work at hand and are coordinated through Komatsu's total vehicle control system to deliver fuel savings and a reduced carbon footprint without compromising machine performance.
 
Komatsu's new EU Stage IV engine integrates SCR to further reduce NOx emissions using the AdBlue® additive. With an advanced electronic control system that manages the airflow rate, fuel injection, combustion parameters and aftertreatment functions, the Komatsu EU Stage IV engine optimises performance, reduces emissions and provides advanced diagnostic capability.
