Core technological innovation in fuel efficiency of PC520LC-11M0
1. Intelligent combustion control system
Adopting Komatsu i-Engine Revolution 2.0 technology, 8-stage injection control is achieved through piezoelectric fuel injectors (accuracy ±0.1ms)
Plateau adaptive mode: Automatically adjust the air-fuel ratio according to altitude (maintaining λ=1.02 when oxygen content is 12%)
Measured data: The fuel consumption during operation at the Qulong Copper Mine in Xizang (at an altitude of 4,200 meters) is 29.5L/h, which is 18% lower than that of the previous generation model
2. Energy-saving design of hydraulic system
Positive flow control + load sensitive dual-mode system to achieve on-demand fuel supply
The main pump efficiency curve shows that the volumetric efficiency reaches 92% under a 40% load condition (the industry average is 85%).
Compound action fuel optimization: The flow distribution error during loading operation is less than 3%, reducing ineffective power loss
3. Energy recovery system
The rotary brake kinetic energy recovery device can save 7.2% of fuel
Intelligent idle speed management system: Automatically enters energy-saving mode after 3 minutes of shutdown (fuel consumption reduced to 1.8L/h)
