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.

C6.4 with ACERT™ Technology

The Cat®C6.4 gives the 320D exceptional power and fuel efficiency unmatched in the
industry for consistently high performance in all applications.

Component Layout. To optimize
efficiency of hydraulic performance,
the hydraulic components are located
close together, which reduces friction
loss and pressure drops in the lines.

System Pressure. System pressure has
been increased to 35,000 kPa (5,076 psi),
which attributes to improved
performance:

• Increased stick and bucket forces
(up 7 percent higher than the 320C)
to better handle those tight digging
conditions

• More drawbar pull (206 kN –
46,322 lb) to provide more ability
to climb slopes, easier spot turns and
improved travel in poor underfoot
conditions

• More lift capacity, generally over
the front where you are generally
hydraulically limited

Heavy Lift. The 320D features the
addition of a heavy lift, which increases
system pressure to 36,000 kPa (5,220 psi),
giving even more lift capacity over
the front. Heavy Lift is activated be
depressing the soft switch on the right
hand console. As the pressure increases,
the engine speed is reduced, which allows
better control while lifting objects.

Pilot System. The pilot pump is
independent from the main pumps and
controls the front linkage, swing and
travel operations.

Hydraulic Cross Sensing System.

The hydraulic cross sensing system
utilizes each of two hydraulic pumps to
100 percent of engine power, under all
operating conditions. This improves
productivity with faster implement
speeds and quicker, stronger pivot turns.

Boom and Stick Regeneration Circuit.

Boom and stick regeneration circuit
saves energy during boom-down and
stick-in operation which increases
efficiency, reduces cycle times and
pressure loss for higher productivity,
lower operating costs and increased
fuel efficiency.

Auxiliary Hydraulic Valve. The auxiliary
valve is standard on the 320D. Control
Circuits are available as attachments,
allowing for operation of high and
medium pressure tools such as shears,
grapples, hammers, pulverizers,
multi-processors and vibratory plate
compactors.

Hydraulic Cylinder Snubbers. Snubbers
are located at the rod-end of the boom
cylinders and both ends of the stick
cylinders to cushion shocks while
reducing sound levels and extending
component life.
