Milton CAT 345D L - Manual (Page 4)

Performance. The 345D L, equipped
with the C13 with ACERT Technology,
meets the U.S. EPA Tier 3 emissions
while providing 10% more horsepower
compared to the 345C L. The building
blocks of ACERT Technology are fuel
delivery, air management, and electronic
control – providing better fuel economy
and reduced wear.
Emissions. ACERT Technology is a
differentiated technology that reduces
emissions at the point of combustion.
The technology capitalizes on
Caterpillar’s proven leadership
in three core engine systems: fuel,
air and electronics.
Fuel System. The Cat C13 features
electronic controls that govern the
mechanically actuated unit fuel injection
(MEUI) system. MEUI provides the
high-pressure required to help reduce
particulate emissions and deliver
better fuel economy through finer
fuel atomization and more complete
combustion.
Controllers. The mechanically actuated
unit injection system features a high-
pressure fuel injection system, proven
to significantly reduce fuel consumption
and particulate emission. Electronic Unit
Injection (EUI) produces high-pressure
and affords the integration of electronics
with fewer components. The modular
design of the electronic control system
allows greater update, flexibility,
improves serviceability and lowers
repair costs.
ADEM™ A4 Engine Controller.
The ADEM™ A4 electronic control
module manages fuel delivery to get
the best performance per liter or 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.
Turbocharger. The Cat C13 uses a
wastegate turbocharger for improved
performance.
• The wastegate valve controls
excessive engine boost pressure
by allowing exhaust to bypass the
exhaust-side turbine.
• The wastegate also reduces turbine
wear in high RPM, low load conditions
and optimizes air and fuel delivery
for peak engine performance.
• The turbocharger increases the density
of the air, enabling the engine to
produce more power with few
effects from altitude.
Low Sound and Vibration Levels.
The engine mounts are rubber-isolating
mounts matched with the engine package
to provide optimum sound and vibration
reduction. Further noise reduction has
been achieved through design changes
to the isolated top cover, oil pan,
multiple injection strategy, insulated
timing cover and sculpted crankcase.
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.
Cooling System. The 345D L layout
completely separates the cooling
system from the engine compartment.
The cooling fan is hydraulically driven
with variable speed control based
on the ambient temperature, coolant
temperature, and hydraulic oil
temperature. This unique feature
assists in the management of engine
power and improves noise efficiency
while providing optimized cooling.
Cold Weather Starting Kit. The optional
kit includes two additional batteries,
heavy-duty battery cables, and the ether
starting aid. With this kit, the 345D L
has the capability to start at –32° C
(–25.6° F).
