Explanation
A general term for the engineering and its social-
ly applied technology of information processing
and communication.
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)
This is a device to detect the angle (or angular
velocity) and acceleration of the 3 axes that con-
trol motions.
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)
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.
This is a filter that captures soot in exhaust gas.
It is built in to KDPF.
This is a catalyst that is used for purifying ex-
haust gas.
It is built in to KDPF or assembled with the muf-
fler.
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.
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.
This is an image display equipment such as a
monitor in which the liquid crystal elements are
assembled.
This is a semiconductor element that emits light
when the voltage is applied in forward direction.
This is one of communication standards that are
used in the network on the machine.
This is a function that detects differential pres-
sure of pump, and controls discharged volume
corresponding to load.
This is one of communication standards that are
used in the network on the machine.
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.
