Cat C9 with ACERT Technology.
The Cat C9 is an 8.8 L (537 in

3

)

displacement, six cylinder, in-line
configured engine with hydraulically
actuated electronic fuel injection or
HEUI™. 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 C9 with ACERT
Technology meets U.S. EPA Tier 3
and European Union Stage IIIa
emissions standards.

Cylinder Block. Increased block and
head material strength minimizes
the effect of high cylinder pressure.
A strengthened flywheel housing joint
reduces leaks. The sculpted heavy-duty
design reduces sound and vibration
levels. The mid-supported liner has
fewer sealing joints for a reduced risk
of leaks. The integral oil cooler reduces
engine width, weight and potential leaks
while improving coolant and oil flow.

Cylinder Head. A new cross-flow air
design with four valves per cylinder
and updated port geometry dramatically
improve airflow and engine breathability.
The cylinder head block features a
robust six-bolt design for an improved
seal between the head and block at the
fire ring which prevents combustion
gas leaks. It also minimizes bore/liner
distortion. The improved intake port
geometry provides a smoother transition
and less flow restrictions.

Fractured-Split Connecting Rods.
The new fractured-split connecting rods
are designed to create near-perfect joint
alignment, maximizing rod bearing life.
This, in combination with a high
efficiency oil filter, ensures long
engine life.
