C11 Engine with ACERT Technology
A combination of innovations working at the point of combustion, ACERT Technology
optimizes engine performance while meeting European EU Stage IIIA emission regulations
for off-road applications.
Cat C11 Engine with ACERT Technology.
The C11 engine provides a full-rated gross
power (SAE J1995) of 261 kW (355 hp)
at 1800 rpm with a torque of 1384 Nm.
The combination of large displacement and
high torque allow the RM300 to propel
through the toughest materials.
Mechanically-Actuated Electronically
Controlled Unit Injection (MEUI).
The MEUI fuel system is a unique system
that combines the technical advancement
of an electronic control system with the
simplicity of direct mechanically controlled
unit fuel injection. The MEUI system 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.
Multiple Injection Fuel Delivery.
Multiple injection fuel delivery involves a
high degree of precision. Precisely shaping
the combustion cycle lowers combustion
chamber temperatures, which generates
fewer emissions, optimizes fuel combustion;
translating into more work output for your
fuel cost.
C11 Cylinder Block. The cylinder
block is a one-piece, grey iron block
that features generous ribbing for
stiffness and heavy bearing bulkheads
for rigidity and strength as the crankshaft turns. This new design supports
the engine’s higher compression ratios
and increases its power density.
The incorporation of straight-thread,
o-ring connection points reduces
the loss of engine oil and fluids.
High Cylinder Pressures.
High cylinder pressures combined
with tightly controlled tolerances
promote extremely efficient fuel burn,
less blow by and lower emissions.
Single Overhead Cam. One single
overhead cam is driven by a gear on
the flywheel end of the engine.
Placing the cam gear at the flywheel
end significantly reduces noise and
vibration. To reduce wear, a pendulum
absorber is mounted at the front of
the camshaft. Together these two
features contribute to the long-life
and durability of this engine.
Service, Maintenance and Repair.
Easier service, maintenance and
repair is accomplished by monitoring
key functions and logging critical
indicators. Advanced electronic
diagnostic capabilities are possible
using Cat Electronic Technician.
Turbocharged and Air-to-Air
Aftercooling (ATAAC).
The turbocharged air-to-air
aftercooling system provides
high horsepower with increased
response time while keeping
exhaust temperatures low for long
hours of continuous operation.
Air-to-Air Aftercooling.
Air-to-air aftercooling keeps air intake
temperatures down and in concert
with the tight tolerance combustion
chamber components, maximizes fuel
efficiency and minimizes emissions.
New turbocharger, unique cross-flow
head, single, rear driven, overhead
cam and a more efficient intake
manifold generate significant
improvements in air flow.
This generates significant
improvements in efficiency
and reduced emissions
ADEM™ A4 electronic Control
Module. The ADEM A4 electronic
control module manages fuel delivery,
valve timing and airflow to get the
most performance per liter of fuel
used. The control module provides
flexible fuel mapping, allowing the
engine to respond quickly to varying
application needs. It keeps track of
engine and machine conditions while
keeping the engine operating at
peak efficiency.
