Variable
Geometry System (VGS) Turbocharger
The
turbocharger has a VGS, which varies the size of the
turbine inlet to maximise the turbocharging effect at
all engine speeds. The benefits include improved torque
and acceleration at the low end of the rev range and
lower emissions of particulate matter (PM). Variations
of the turbine inlet size in eight increments has been
replaced with stepless variation resulting in more
precise control.
Electronically Controlled Common-Rail System
The
electronically controlled common-rail system enables
high pressure fuel injection with optimal control over
the injection timing and injection amount. It promotes
fuel economy and helps to limit harmful exhaust
emissions.
Electronically Controlled, Cooled Exhaust Gas
Recirculation (EGR) System
The EGR
system reduces emissions of nitrogen oxides (NOx) by
directing exhaust gases into the engine for recombustion.
It incorporates an EGR cooler, which heightens
performance by cooling the recalculating gases.
Automated
Manual Transmission (AMT)*
Based on a
manual transmission. AMT - Automated manual Transmission
- offers complete electronic control for easy, automatic
gear shifting or a choice of sequential manual shifting.
AMT does away with the clutch pedal, and its Econo mode
provides automatic shifting, changing gears as necessary
to maximize fuel efficiency. Fuel economy and engine
braking power are both equivalent to vehicles equipped
with manual transmissions, and maintenance costs
associated with a clutch are climinated. AMT promises a
wide range of cost benefits.
*(Optional
Feature)
Diesel
Particulate Defuser (DPD)
Efficient
combustion of PM captured by a ceramic filter is
realised by Isuzu-developed exhaust-temperature
control., which is made possible partly by the precise
fuel-injection control of the electronically controlled
common-rail system and partly by an exhaust throttle. As
the accumulated PM is burned away, the ceramic filter is
regenerated. Filter regeneration is performed
automatically during vehicle operation. Depending on
operating conditions, manually initiated regeneration
while the engine is idling can also be necessary.
