Actual word spelled out
Purpose of use (major ap-
plicable machine (*1), or
component/system)
Explanation
ICT
Information and Com-
munication Technology
Communication and elec-
tronic control
A general term for the engineering and its social-
ly applied technology of information processing
and communication.
IMA
Inlet Metering Actuator
Engine
This is a valve that adjusts the fuel intake amount
at the pump inlet in order to control the supply
pump fuel discharged volume. (Same as IMV)
IMU
Inertial Measurement
Unit
Engine
This is a device to detect the angle (or angular
velocity) and acceleration of the 3 axes that con-
trol motions.
IMV
Inlet Metering Valve
Engine
This is a valve that adjusts the fuel intake amount
at the pump inlet in order to control the supply
pump combustion discharged volume. (Same as
IMA)
KCCV
Komatsu Closed Crank-
case Ventilation
Engine
This is a mechanism that burns the blowby gas
again by separating oil from blowby gas and re-
turning it to the intake side. It primarily consists of
filters.
KCSF
Komatsu Catalyzed
Soot Filter
Engine
This is a filter that captures soot in exhaust gas.
It is built in to KDPF.
KDOC
Komatsu Diesel Oxida-
tion Catalyst
Engine
This is a catalyst that is used for purifying ex-
haust gas.
It is built in to KDPF or assembled with the muf-
fler.
KDPF
Komatsu Diesel Particu-
late Filter
Engine
This is a component that is used to purify the ex-
haust gas. KDOC (catalyst) and KCSF (filter to
capture soot) are built-in it.
It is installed instead of the conventional muffler.
KTCS
Komatsu Traction Con-
trol System
Travel and brake
This is a function that performs braking with the
optimum force and recovers the driving force of
the wheels by actuating the inter-axle differential
lock when the wheels runs idle while the machine
travels on the soft ground.
(HM)
LCD
Liquid Crystal Display
Machine monitor
This is an image display equipment such as a
monitor in which the liquid crystal elements are
assembled.
LED
Light Emitting Diode
Electronic parts
This is a semiconductor element that emits light
when the voltage is applied in forward direction.
LIN
Local Interconnect Net-
work
Communication and elec-
tronic control
This is one of communication standards that are
used in the network on the machine.
LS
Load Sensing
Hydraulic system
This is a function that detects differential pres-
sure of pump, and controls discharged volume
corresponding to load.
LVDS
Low Voltage Differential
Signaling
Communication and elec-
tronic control
This is one of communication standards that are
used in the network on the machine.
MAF
Mass Air Flow
Engine
This indicates engine intake air flow. This is not
used independently but is used as combined with
sensor. Mass air flow sensor can be called as
MAF sensor.
