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 LRR, equipped
with the C6.4 engine with ACERT™
Technology, provides 7% more power as
compared to the 3066TA in the 320C LU.
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.
