Cat C7 ACERT™. The Cat
®
C7 with
ACERT™ Technology gives the
325D FM exceptional power and fuel
efficiency unmatched in the industry.
The C7 meets U.S. EPA Tier 3 emissions
requirements. The forestry designed
hydraulics give the 325D FM exceptional
power, efficiency and controllability
unequaled in the industry for consistently
high performance in all forestry
applications.
Performance. The 325D FM is
equipped with the C7 ACERT engine,
which provides 12% more horsepower
as compared to the 3126B ATAAC
HEUI engine.
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 C7 ACERT
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 optional programmable reversible
fan allows for radiator blowout, to
increase service intervals and to maintain
engine operational temperatures.
The optimum fan speed is calculated
based on the target engine speed, coolant
temperature, hydraulic oil temperature
and actual fan speed. The Cat C7 ACERT
delivered a completely new layout that
separates the cooling system from the
engine compartment.
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.
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.
