Engine
Diesel Engine
The Cat C18, with ACERT Technology, is an 18.1 L, six-cylinder, 390 kW (530 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
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° C. 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 proven Caterpillar 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 excavator has the capability to start at –32° C.
Environmentally Responsible Design
Outstanding Performance
Many features are designed to provide outstanding performance, which can mean more work done in a day, less fuel consumption, and minimal impact on our environment.
Low Exhaust Emissions
The Cat C18 diesel engine utilizes unique ACERT Technology to meet exhaust emissions regulations while assuring optimum fuel efficiency.
Quiet Operation
The hydraulically driven cooling fan is thermostatically controlled so the fan only runs at the speed necessary to maintain correct system operating temperatures. The result is cool, quiet operation with less disturbance to the surrounding environment.
Ozone Protection
To help preserve the earth's ozone layer, the air conditioning unit uses only R-134a refrigerant, which does not contain harmful chlorofluorocarbons (CFC's).
Fewer Leaks and Spills
Engine oil and encapsulated hydraulic oil filters are positioned vertically and are easy to reach to minimize spillage. Service intervals are extended to reduce the times fluids are changed and handled. The new hydraulic oil fine filtration system attachment extends the service interval from 2,000 to 5,000 hours. Compatible with Cat HEES hydraulic bio-oil for ecologically sensitive applications. Finally, the new Cat Extended Life Coolant extends service (up to 6,000 hours) so there is less need for fluid disposal.

The hydraulic system includes a three-pump system with an independent swing circuit and a hydraulic circuit utilizing the proven Proportional Priority Pressure Compensated (PPPC) system. Cat electronic control and activation ensures high hydraulic system efficiency and excellent productivity.
PPPC System
The PPPC system provides many advancements. Cylinder speed is directly related to the operator's movement of the joystick from feathering to full speed. Flow to cylinders during multi-functional operation is directly controlled by the operator and is not dependent on loads. Also, the controller reduces pump output to save power when joysticks are in the neutral position.
Power Management Control
The pump valve electronic controller is central to power management control and provides highly efficient control for the pumps, valves, and engine.
Swing Performance
The three-pump system with independent swing gives priority to the swing circuit for strong swing acceleration and easily controlled multi-function operation.
