Cat
®
C32 engine with ACERT™
Technology. With the C32 engine,
Caterpillar optimizes engine
performance while meeting U.S. EPA
Tier 2 and European Union Stage II
regulations. ACERT™ Technology
reduces emissions during the combustion
process by using advanced technology
in the air and fuel systems, in conjunction
with integrated electronics. Caterpillar
meets emission regulations at the
combustion source, rather than
recycling exhaust.
Engine Design. The Cat C32 engine uses
ACERT Technology and iron-specific
features to deliver strong performance
and long-term durability.
EPA Emissions Compliant. The C32
engine is compliant with U.S. EPA Tier 2
and European Union Stage II emissions
regulations, reducing NOx 27.5 percent
from 4.8 g/bhp-hr to 3.0 g/bhp-hr over
the 3508B.
Altitude Compensation. Electronic engine
control automatically compensates for
load demand, high-altitude conditions
and cold starting.
Single-Piece Piston Design.
New single-piece forged steel pistons
with integrated forged steel skirt are
more robust to withstand high engine
heat and pressure, and enable enhanced
combustion efficiency, improved fuel
efficiency and lower emissions.
Corrosion-resistant, stainless steel top
ring reduces ring, groove and liner wear
for greater reliability and longer life.
MEUI Fuel System. Fuel delivery,
provided by the MEUI mechanically
actuated electronic unit injection system,
involves a high degree of precision.
Precisely shaping the combustion cycle
lowers combustion chamber temperatures,
generating fewer emissions and
optimizing fuel combustion. The system
senses operating conditions and regulates
fuel delivery for optimum fuel efficiency,
improved response times, lower emissions
and less smoke.
Electronic Control Module (ECM).
ECM uses advanced engine management
software to monitor, control and protect
the engine using self-diagnosing
electronic sensors. The computerized
system senses operating conditions and
power requirements and adjusts the
engine for peak performance and the
most efficient operation at all times.
Advanced Diesel Engine Management
A4 Engine Controller. The ADEM™ A4
electronic control module delivers
optimum fuel performance. 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.
Oil Renewal System (optional). The oil
renewal system meters and injects used
engine oil from the crankcase to the
engine’s fuel return line, extending oil
change intervals and increasing machine
availability and productivity.
