Milton CAT 320D L - Manual (Page 4)

Cat C6.4. The Cat C6.4 with ACERT™
Technology introduces a series of
evolutionary, incremental improvements
that provide breakthrough engine
technology. 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 emission regulations. With its
proven technology, robust components
and precision manufacturing, you can
count on this engine to power up at start
time and keep working productively all
shift long.
Performance. The 320D, equipped
with the C6.4 engine with ACERT™
Technology, provides 7 percent more
power as compared to the 3066TA in
the 320C L. The additional power
delivers a speed and efficiency
advantage in high production
applications.
Automatic Engine Speed Control.
The two-stage, one-touch control
maximizes fuel efficiency and reduces
sound levels.
ADEM™ A4 Engine Controller.
The ADEM A4 electronic control
module manages fuel delivery to get the
best performance per liter of fuel used.
The engine management system provides
flexible fuel mapping, allowing the
engine to respond quickly to varying
application needs. It tracks engine and
machine conditions while keeping the
engine operating at peak efficiency.
Electronic Control Module.
The Electronic Control Module (ECM)
works as the “brain” of the engine’s
control system, responding quickly to
operating variables to maximize engine
efficiency. Fully integrated with sensors
in the engine’s fuel, air, coolant, and
exhaust systems, the ECM stores and
relays information on conditions such
as rpm, fuel consumption, and
diagnostic information.
Fuel Delivery. The Cat C6.4 features
electronic controls that govern the fuel
injection system. Multiple injection
fuel delivery involves a high degree
of precision. Precisely shaping the
combustion cycle lowers combustion
chamber temperatures, generating
fewer emissions and optimizing fuel
combustion. This translates into more
work output for your fuel cost.
Cooling System. The cooling fan
is directly driven from the engine.
An electrically controlled viscous clutch
fan is available as an attachment to reduce
fan noise. The optimum fan speed is
calculated based on the target engine
speed, coolant temperature, hydraulic
oil temperature and actual fan speed.
When fan speed is reduced, there’s more
power available for other functions –
and less fuel is burned.
