ACERT Technology. The C11 ACERT
engine introduces a series of evolutionary,
incremental improvements that provide
breakthrough engine technology built
on systems and components developed
by Caterpillar with proven reliability.
The technology capitalizes on Caterpillar
expertise in four core engine systems:
fuel, air, electronics and after treatment.
ACERT technology is a unique and
revolutionary systems solution that
enables Cat engines to meet today’s
clean air regulations, thus establishing
the building blocks for attaining
tomorrow’s more stringent standards.
C11 Block. The one-piece, gray iron
block features generous ribbing for
stiffness and heavy bearing bulkheads
for rigidity and strength as the crankshaft
turns. Straight O-ring connection points
reduce the loss of engine oil and fluids.
Cylinder Head and Piston Technology.
The C11 has a cross-flow cylinder head
with refined port geometry, which
improves breathing and provides better
combustion. The Monotherm/steel
pistons have a forged steel design, which
offers high strength, light weight and
tighter tolerances. The result is better
oil control, minimal blow-by and long
liner life.
Advanced Diesel Engine Management
(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.
Fuel Delivery. 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.
Noise Reduction Technologies.
Noise reduction has been achieved
through design changes to the isolated
top cover, oil pan, multiple injection
strategy, insulated timing case cover,
sculpted crankcase and gear train
refinements.

Cat C11 Engine with ACERT Technology
A combination of proven systems and innovative new technologies, ACERT engines optimize
performance while meeting EPA Tier 3 and EU Stage 3a engine exhaust emission regulations.
Page 5
Mechanically Actuated Electronic
Unit Injection (MEUI). A highly evolved
fuel system with a proven record of
reliability in the field. It combines the
technical advancement of an electronic
control system with the simplicity
of direct mechanically controlled unit
fuel injection. It excels in its ability
to control injection pressure over the
entire engine operating speed range.
These features allow the C11 to have
complete control over injection timing,
duration, and pressure.
Air-to-Air Aftercooling (ATAAC).
ATAAC keeps air intake temperatures
down and, in concert with the tight
tolerance combustion chamber
components, maximizes fuel efficiency
and minimizes emissions. Significant
improvements in airflow are generated
by a turbocharger, unique cross-flow
head and a single overhead camshaft.
Wastegate Turbocharging. Single
wastegate turbocharger provides higher
boost over a wide range, outstanding
low-end performance with improved
peak torque and enhanced engine
response.
Electronic Transmission. The Caterpillar
six-speed electronically controlled
transmission is designed specifically for
the articulated truck and its applications.
It features anti-hunt shift strategy for
speed continuity.
Electronic Clutch Pressure Control.
ECPC technology works with Controlled
Throttle Shifting to manage shift torque
and provide exceptional shift smoothness.
Controlled Throttle Shifting (CTS).
Significantly reduces power train stress
and clutch wear by controlling engine
speed, torque converter lock-up and
transmission clutch engagements.
Engine Overspeed Inhibitor. Electronic
Transmission Control (ETC) protects
against engine overspeeding by shifting
the transmission up one gear at specified
rpm settings. If the transmission is in its
highest gear, torque converter lockup
disengages.
Directional Shift Management.
Regulates engine speed during directional
shifts to prevent damage caused by
high-speed directional changes.
Programmable Top Gear Selection.
Electronic Transmission Control lets
you electronically limit top gear selection
without the use of additional service
tooling or mechanical limiting of
the shift cane.
Retarder. Integral retarder with
high-power density design. Due to its
compact size, the unit quickly fills with
oil, providing more retarding power
and fast response times.
Usable Rimpull. Power train components
work together to offer more usable
rimpull at higher speeds on effective
grades. In first gear, the torque converter
overcomes grade resistance by sending
more torque to the wheels and preventing
engine lugging. On downhill grades,
the retarder acts like a brake by slowing
the machine.
Hydraulic Fan. The remote-mounted
hydraulic fan is temperature sensitive
providing variable speeds when needed,
which minimizes power requirements.
The result is more power to the ground
and faster cycle times.

Performance and Productivity – Power Train
Integrated power train with more power, greater performance and lower fuel consumption –
the power to do more work.
Page 6
Front Suspension. The three-point front
suspension permits the axle to oscillate
±6°, softening impact loads on structures
and components and providing a smooth
ride, so the operator can travel at speed
over rough terrain.
A-Frame Construction. The front
suspension uses an oscillating A-frame
with a lateral tie rod to control axle
sideways movement.
Front Suspension Cylinders. Large bore,
low pressure cylinders are purpose
designed for tough applications and
offer a soft, smooth ride.
Mounting Points. Suspension mounting
points are integrated into the axle housing,
increasing reliability.
Rear Suspension. Features a walking
beam geometry with Caterpillar designed
rear suspension mounts which provide
a reliable and stable ride for excellent
load retention.
Suspension Design. Center and rear
axle castings mount to A-frames, which
attach to the rear frame by lateral tie rods
and sealed, steel spherical bearings; steel
bearings increase load-carrying capacity.
The rugged low-maintenance system
allows oscillation and independent wheel
movement. The rear suspension design
optimizes stability, traction and flotation.
Traction Control. The traction control
system is comprised of a wet clutched
inter-axle differential and wet clutched
cross-axle differentials. All differentials
can be engaged and disengaged on-thego for maximum versatility. When used
together, the differentials provide
100 percent driveline locking.
Inter-Axle Differential Lock. Locks all
three axles in unison and modifies
torque distribution for excellent traction
in poor underfoot conditions and on
grades. It is operated by a switch
located at the footrest.
Cross-Axle Differential Locks.
Provides full driveline locking –
all three axles and all six wheels –
for maximum performance in the most
adverse conditions. Acts in unison with
the inter-axle differential lock when the
footswitch is actuated and the dashmounted switch is selected.
Exhaust Heat System. The body comes
exhaust heat ready.
Steering System. Cat articulated trucks
use a load-sensing steering system for
smooth, precise control. It features a
single, variable displacement pump.
Two double-acting, cushioned steer
cylinders allow the machine to articulate
45° to the left or right, permitting precise
positioning in tight areas. Its compact
Hand Metering Unit controls the
cylinders for responsive steering and
performance. An electronic secondary
steering system is standard.

and soft underfoot conditions.
Versatility. The 730 Ejector is based
on the standard 730 Articulated Truck
and shares all its versatility. Similar in
design to the well proven 740 Ejector
model, the 730 Ejector can operate in
the same conditions. The 730 Ejector
offers a number of unique capabilities
that stretches the operation envelope.
Spreading. The truck can eject the
material and spread it out while moving,
reducing the size of additional spreading
and dozing equipment. This makes the
730 Ejector an ideal solution for road
building and landfill applications.
On-the-go ejecting results in faster cycle
times and reduced power train loads.
Stability. Ejecting the load without
raising the body increases stability,
allowing load dispersal on inclines,
side slopes, and in very soft underfoot
conditions such as landfill sites.
Generally, these conditions would be
unacceptable with a conventional truck,
but are ideal for the 730 Ejector.
Overhead Clearance. Because the body
is not raised when ejecting the load,
the truck can be utilized in areas with
reduced overhead clearance such as
when working around overhead lines,
conveyors, hoppers and bridges.
The ejector is also ideal for tunneling
and underground operations.
Carry-Back. The design of the ejector is
inherently self-cleaning and practically
eliminates material sticking to the body,
which increases productivity, improves
fuel efficiency and lowers cost per ton.
Body. Reinforced body is made from
thick high-yield, heat-treated Brinell
hardened steel (Brinell 450 on the base
and Brinell 400 on the sides) that provides
exceptional durability. Ejector top rails
are made from high-strength alloy steel.
For optimum durability and wear life,
the ejector body is designed to work in
applications where the material consists
of rocks smaller than 152 mm (6 in.)
in diameter.
Blade. The ejector blade is made from
high-strength steel and uses technology
similar to that proven in Cat wheel
tractor-scrapers.
Cylinder. A three-stage, high-speed,
double-acting cylinder is specifically
designed for horizontal mounting and
provides smooth load ejection. It is
centrally supported and nitride-hardened
to ensure a long service life.
Proven Technology. Much of the
730 Ejector design is carried over from
the standard Cat 730 Articulated Truck.

TOTAL RESISTANCE %
(GRADE PLUS ROLLING RESISTANCE)
Retarding Performance
To determine performance, read from
Gross Weight down to % Effective Grade.
Effective Grade equals actual % favorable
grade plus 1% for each 10 kg/metric ton
(20 lb/ton) of Rolling Resistance. From this
point, read horizontally to the curve with
the highest attainable speed range. Then, go
down to Maximum Speed. Retarding effect
on these curves represents full application of
the retarder.
