Milton CAT M322D - Manual (Page 4)

Powerful Performance. The Cat ® C6.6
with ACERT™ Technology introduces
a series of evolutionary, incremental
improvements that provide breakthrough
engine performance. The building blocks
of ACERT Technology are fuel delivery,
air management and electronic control.
ACERT Technology optimizes engine
performance while meeting U.S. EPA
Tier 3 engine emission regulations.
The Cat C6.6 engine in the M322D
delivers a maximum gross power of
130 kW (174 hp) at a rated speed
of 2,000 rpm.
Low Fuel Consumption. The C6.6 is
electronically controlled and uses the
new Cat Common Rail Fuel System and
fuel pump. This combination provides
outstanding fuel consumption during
both production and travel. When the
system recognizes roading application
the engine adjusts to the most efficient
system operating point to save fuel
without compromising road performance.
Low Noise, Low Vibration. The Cat C6.6
design improves operator comfort by
reducing sound and vibration.
Cooling System. An electronically
controlled, hydraulic motor drives a
variable speed on-demand fan for engine
coolant and hydraulic oil. The optimum
fan speed is determined based on
coolant and hydraulic oil temperature
resulting in reduced fuel consumption
and lower sound levels. The electronic
engine control continuously compensates
for the varying fan load, providing
consistent net power, regardless of
operating conditions.
One-Touch Low Idle Control.
The two-stage, one-touch Automatic
Engine Speed Control reduces engine
speed if no operation is performed,
maximizing fuel efficiency and
reducing sound levels.
Waste Handling Package. The Waste
Handling Package has been specifically
developed for Cat Wheel Excavators
working in waste transfer stations or
other extremely dusty applications.
This option features the following:
• An automatic, hydraulic reversible
fan that reverses airflow after a
set interval, manually adjustable
between 5 and 60 minutes with a
switch located inside the cab.
• A special dense wire mesh cooling
system hood further reduces radiator
clogging.
• Two cyclone filters provide clean
filtered air to the engine compartment,
air cleaner, aftercooler and air
conditioner condenser.
