1.
Smart engine speed control
This mode enhances fuel efficiency by reducing engine
speed in the low load range to appropriate level through
variable engine speed control which is carried out by
detecting actual engine load and the operator's control
action for heavy load operations, such as boom up and
arm crowd.
•
Heavy load: increase engine speed
→
maximize work
performance
•
Low load: decrease engine speed
→
maximize fuel
efficiency
2.
Smart pump torque control
This mode reduces smoke and increases fuel efficiency by
reducing unnecessary engine load through optimized
control of pump torque in accordance with the engine
torque.
