ACERT Technology. The Cat 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.
