C15 Engine with ACERT™ Technology
A combination of innovations working at the point of combustion, ACERT Technology
optimizes engine performance while meeting U.S. EPA Tier 3 and European EU Stage IIIa
emission regulations for off-road applications.
Cat ® C15 Engine with ACERT Technology
The C15 engine provides a full-rated
gross power (SAE J1995) of 403 kW
(540 hp) at 2000 rpm with a torque of
2356 Nm (1738 lb/ft). The combination
of large displacement and high torque
allow the RM-500 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 C15 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 and
optimizes fuel combustion, translating
into more work output for your fuel
cost.
C15 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.
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, front 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 gallon (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.
