Cat ® C6.6 Engine with ACERT™
Technology. The Cat ® C6.6 is a
6.6 liters (403 in 3 ) displacement,
six cylinder, inline configured engine
equipped with a Caterpillar Common
Rail fuel System. It uses ACERT
Technology, a series of Caterpillar
engineered innovations that provide
advanced electronic control, precision
fuel delivery and refined air management,
resulting in outstanding performance
and lower emissions. The Cat C6.6 with
ACERT Technology meets the U.S. EPA
Tier 3, European Union Stage IIIA and
Japan MOC Step 3 emissions standards.
Design. The C6.6 features a compact
design with heavy-duty engine features
for outstanding durability, reliability
and performance. The C6.6 incorporates
a new cross flow cylinder head design,
a 4 valve head and an ADEM A4
electronic controller.
Electronic Controls. The C6.6 engines
use advanced electronic controllers,
which have a proven track record for
performance and reliability. ADEM A4
Electronic Control Module (ECM)
receives data from engine-mounted
sensors and adjusts critical parameters
to maintain optimum performance.
These adjustments also optimize fuel
economy and emissions compliance.
Electronics also make engines easier
to troubleshoot and repair.
Fuel Delivery. Fuel is introduced in
the combustion chamber in a number
of precisely controlled microbursts.
Injecting fuel in this way allows for
precise shaping of the combustion
process. The ADEM™ A4 module
directs the injectors to deliver precise
quantities of fuel at exactly the right
times during combustion for optimum
efficiency and performance.
Air Management. The C6.6 uses a
turbocharger fitted with a smart waste
gate to give precise control of the boost
pressure. Over the entire engine operating
ranges the result is improved: Throttle
response, Lower fuel Consumption and
optimized engine performance. A new
cross-flow design in the cylinder head
facilitates air movement, while tighter
tolerances between the piston and
cylinder liner are reducing blow by gases.
Turbocharged and Aftercooled. A well-
matched turbocharger and air-to-air
aftercooler results in higher power while
keeping rpm steady and exhaust
temperatures low.
Torque Rise. The direct injection
electronic fuel system provides a
controlled fuel delivery increase as
the engine lugs back from rated speed.
This results in increased horsepower
below rated power. A combination
of increased torque rise and maximum
horsepower improves response,
provides greater drawbar pull and
faster dozing cycles.
Cooling System. The cooling system is
a single coolant unit including hydraulic
oil cooler, radiator, ATAAC and fan
installation. Aluminum cores and
hydraulically driven demand fan provide
optimum cooling and fuel efficiency.
Electric Fuel Priming Pump. A standard
electric fuel priming pump is located in
the primary fuel filter base above the
combined water separator/primary fuel
filter. A switch enables to easily prime
the fuel system after a fuel filter service.
