Diesel Engine. The Caterpillar C18,
with ACERT technology, is a 18.1 liter,
six-cylinder, 382 kW (513 hp) engine
with mechanically actuated electronic
fuel injection (MEUI) and overhead
camshaft. ACERT technology provides
outstanding engine performance through
advanced electronic control, precision
fuel delivery, and refined air management.
Fuel Consumption. The Advanced Diesel
Engine Management (A4) controller
uses sensors throughout the engine to
manage engine load and performance.
The A4 controller is the muscle behind
engine responsiveness, self-diagnostics,
controlling emissions, and fuel economy.
Fuel System. C18 engine uses a
mechanically actuated electrically
controlled unit injection (MEUI) system.
The MEUI system combines high-
pressure injection and electronic control
in a single compact unit. The electronic
unit injector is an integral part of the
C18 fuel system. Computerized electronic
control provides precise metering and
timing of fuel injection.
Cooling System. High capacity,
side-by-side cooling system allows
operation in ambient temperatures
up to 52 degree C (126 degree F).
The Electric Power Control (EPC)
controls the fan speed based on coolant
temperature and hydraulic oil temperature
for optimized cooling.
Turbocharger. The C18 engine uses a
water-cooled, center-section waste gated
turbocharger for improved performance.
This turbocharger controls the air volume
to the cylinders and works efficiently
during low and high load conditions.
Emissions. ACERT Technology is a
differentiated technology that reduces
emissions at the point of combustion.
The technology capitalizes on
Caterpillar’s proven leadership in
three core engine systems: fuel, air
and electronics.
Cold Weather Starting Kit. The kit
consists of two additional batteries,
heavy-duty harness, large capacity
starting motor, and the ether starting
aid. With this kit, the 385C L has the
capability to start at –32 degree C
(–25.6 degree F).

Engine
A combination of innovations working at the point of combustion, ACERT technology
optimizes engine performance while meeting EPA Tier 3 emission regulations.
