Milton CAT 336D L - Manual (Page 4)

Cat C9. The Cat C9 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 for
off-road applications.
Performance. The 336D L, equipped
with the C9 engine with ACERT™
Technology, provides 9% more
horsepower as compared to the C9
in the 330C L.
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 C9 features
electronic controls that govern the unit
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
hydraulically driven and controlled
by the ECM. The optimum fan speed
is calculated 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. Cat C9 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.
