C7 with ACERT™ Technology
Built for power reliability, economy and low emissions.
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 C7 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 utilized 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.
The 328D LCR incorporates side by
side cooling, allowing easy access to
keep the cooling cores free of debris.
Automatic Engine Speed Control.
The two-stage, one-touch control
maximizes fuel efficiency and
reduces sound levels.
Cat® C7 ACERT. The Cat C7 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 engine emission regulations.
Air Cleaner. The radial seal air filter
features a double-layered filter core
for more efficient filtration and is
located in a compartment behind the
cab. A warning is displayed on the
monitor when dust accumulates above
a preset level.
ADEM™ A4 Engine Controller.
The ADEM A4 electronic control
module manages fuel delivery to get
the best performance per liter (gallon)
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.
Noise Reduction Technologies.
The engine mounts are rubber-isolating
mounts matched with the engine package.
Further noise reduction has been
achieved through design changes to
the isolated top cover, oil pan, multiple
injection strategy, insulated timing
cover, sculpted crankcase and gear train
refinements.
Performance. The 328D LCR,
equipped with the C7 engine with
ACERT Technology, provides 8% more
horsepower as compared to the 3126B
ATAAC HEUI in the 325C LCR.

Hydraulics
Cat® hydraulics deliver power and precise control to keep material moving.
Component Layout. The hydraulic
system and component locations have
been designed to provide a high level
of system efficiency. The main pumps,
control valves and hydraulic tank are
located close together. This allows
for shorter tubes and lines between
components, which reduce friction loss,
and pressure drops in the lines. The layout
further provides greater operator comfort
by placing the radiator on the cab side
of the upper structure. This allows
incoming air to enter the engine
compartment from the operator side.
Hot air and corresponding engine sound
exits on the opposite side away from
the operator. This reduces engine
compartment heat and sound being
transmitted to the operator.
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.
Auxiliary Hydraulic Valve. The auxiliary
valve is standard on the 328D LCR.
Control Circuits are available as
attachments, allowing for operation
of high and medium pressure tools.
These include shears, grapples, hammers,
pulverizers, multi-processors and
vibratory plate compactors.
Hydraulic Cylinder Snubbers.
Boom and Stick Regeneration Circuit.
Boom and stick regeneration circuit
saves energy during boom-down and
stick-in operation. This increases
operator efficiency, reduces cycle times
and pressure loss. Benefits include higher
productivity, lower operating costs and
increased fuel efficiency.
Snubbers are located at the rod-end of
the boom cylinders and both ends of the
stick cylinders. Benefits include reducing
sound levels, cushion shocks while
extending component life.
