Environmentally Responsible Design
Caterpillar machines not only help you build a better world, they help maintain
and preserve the fragile environment.
Outstanding performance.
Many features designed to provide
outstanding performance which
can mean more work done in a day,
less fuel consumption and minimal
impact on our environment.
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.
Quiet operation.
The hydraulically
driven cooling fan is thermostatically
controlled, so the fan only runs at the
speed necessary to maintain correct
system operating temperatures. The
result is cool quiet operation with less
disturbance to the surrounding
environment.
Ozone protection.
To help preserve
the earth’s ozone layer, the air
conditioning unit uses only R-134a
refrigerant which does not contain
harmful chlorofluorocarbons (CFC’s).
Fewer leaks and spills.
Engine oil and
encapsulated hydraulic oil filters are
positioned vertically and are easy to reach
to minimize spillage. Service intervals are
extended to reduce the times fluids are
changed and handled. The new hydraulic
oil fine filtration system attachment
extends the service interval from 2000 to
5000 hours. Compatible with Cat HEES
hydraulic bio-oil for ecologically sensitive
applications. Finally, the new Cat
Extended Life Coolant extends service
(up to 6000 h) so there is less need for
fluid disposal.
Engine
Built for power, reliability, economy and low emissions.
Performance.
The Cat C13 engine
with ACERT Technology offers 21%
greater displacement than the 3176C,
and runs at 10% lower speeds for better
fuel economy and reduced wear.
Fuel Consumption.
ADEM A4 controller
uses sensors throughout the engine to
manage engine load and performance.
The ADEM A4 controller is the muscle
behind engine responsiveness, self-
diagnostics, controlling emissions,
and fuel economy.
Low Sound and Vibration Levels.
The engine mounts are rubber-isolating
mounts matched with the engine
package to provide optimum sound and
vibration reduction. Another benefit of
ACERT Technology, the C13 engine
can shape the rate of fuel injection,
a process that reduces engine noise
levels and vibration.
Fuel System.
The Cat C13 ACERT
engine 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.
Cooling System.
The 345C L layout
separates the cooling system from the
engine compartment. The cooling fan
is hydraulically driven with a variable
speed control that manages fan speed
to provide optimized cooling.
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.
Turbocharger.
The Cat C13 ACERT
engine uses a Wastegate Turbocharger
for improved performance.
Cold Weather Starting Kit.
The kit
consists of four batteries, heavy-duty
harness, large capacity starting motor
and the ether starting aid. With this kit,
the 345C L has the capability to start
at -32°C.
