Caterpillar Equipment
Engine
The Cat C18 ACERT® has state-of-the-art technology to meet U.S. EPA Tier 3 emission regulations, with exceptional performance capabilities and proven reliability.
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 ADEM„¢ A4 controller uses sensors throughout the engine to manage engine load and performance. The ADEM A4 controller is the muscle behind engine responsiveness, self-diagnostics, controlling emissions, and fuel economy.
Fuel System
The C18 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 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 Caterpillars 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).
Hydraulics
Proportional Priority Pressure Compensated (PPPC) system with state-of-the-art electronic control ensures hydraulic system efficiency and excellent productivity.
PPPC Hydraulics
Load sensing, Proportional Priority Pressure Compensation (PPPC) system, with Caterpillar-developed electronic actuation, provides high efficiency and excellent controllability.
