Explanation
Electronic control device that uses the signals
from the sensors on the machine to indicate the
optimum actuation to the actuators . (Same as
ECU)
Proportional electromagnetic valve that gradually
increases oil pressure to engage clutch and
reduces transmission shock.
System that ensures smooth high-speed travel by
using hydraulic spring effect of accumulator to
absorb vibration of machine during travel
Electronic control device that uses the signals
from the sensors on the machine to indicate the
optimum actuation to the actuators. (Same as
ECM)
Function to recirculate part of exhaust gas to
combustion chamber in order to reduce
combustion temperature and to control emission
of NOx.
System that allows data (filter, oil replacement
interval, malfunctions on machine, failure code,
and failure history) from each sensor on the
machine to be checked on monitor.
Electromagnetic proportional control Mechanism
that actuator works in proportion to current
Structure that protects operator's head from falling
objects. (Structure to protect operator)
Performance standardized in ISO 3449
Forward - NEUTRAL - REVERSE
Global Positioning System Satellite positioning
system that is used to determine the current
location on the earth
Steering function that uses a combination of
hydraulic motor and bevel shaft to control
difference in travel speed of right and left tracks to
turn machine without using steering clutch.
Hydraulic transmission system that uses a
combination of hydraulic pump and hydraulic
motor to shift gear steplessly without using gears.
Valve that adjusts fuel intake amount at inlet port
of pump in order to control fuel discharge amount
of supply pump. Same meaning as IMV
Valve adjusting fuel intake amount at inlet port of
pump in order to control fuel discharge amount of
supply pump. Described IMV (IMA)
This mechanism separates oil in blowby gas and
returns it to the intake side to afterburn it there. It
primarily consists of filters.
