C9 with ACERT™ Technology
The Cat® C9 gives the 336D L exceptional power and fuel efficiency unmatched in the industry for consistently high performance in all applications.
Cat C9. The Cat C9 with ACERT™ Technology introduces a series of evolutionary, incremental improvements that provide breakthrough engine technology. The building blocks of ACERT Technology are fuel delivery, air management and electronic control. ACERT Technology optimizes engine performance while meeting U.S. EPA Tier 3 engine emission regulations for off-road applications.
Performance. The 336D L, equipped with the C9 engine with ACERT™ Technology, provides 9% more horsepower as compared to the C9 in the 330C L.
Automatic Engine Speed Control.
The two-stage, one-touch control maximizes fuel efficiency and reduces sound levels.
ADEM™ A4 Engine Controller.
The ADEM A4 electronic control module manages fuel delivery to get the best performance per liter of fuel used. 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.
Electronic Control Module.
The Electronic Control Module (ECM) works as the “brain” of the engine’s control system, responding quickly to operating variables to maximize engine efficiency. Fully integrated with sensors in the engine’s fuel, air, coolant, and exhaust systems, the ECM stores and relays information on conditions such as rpm, fuel consumption, and diagnostic information.
Fuel Delivery. The Cat C9 features electronic controls that govern the unit fuel injection system. Multiple injection fuel delivery involves a high degree
of precision. Precisely shaping the combustion cycle lowers combustion chamber temperatures, generating fewer emissions and optimizing fuel combustion. This translates into more work output for your fuel cost.
Cooling System. The cooling fan is hydraulically driven and controlled by the ECM. The optimum fan speed is calculated based on the ambient temperature, coolant temperature and hydraulic oil temperature. This unique feature assists in the management of engine power and improves noise
efficiency. Cat C9 delivered a completely new layout that separates the cooling system from the engine compartment.
Air Cleaner. The radial seal air filter features a double-layered filter core for more efficient filtration and is located in a compartment behind the cab. A warning is displayed on the monitor when dust accumulates above a preset level.
Noise Reduction Technologies.
The engine mounts are rubber-isolating mounts matched with the engine package. Further noise reduction has been achieved through design changes to the isolated top cover, oil pan, multiple injection strategy, insulated timing cover, sculpted crankcase and gear train refinements.

Hydraulics
Cat® hydraulics deliver power and precise control to keep material moving.
Component Layout. The component location and hydraulic system design provide the highest level of system efficiency. The main pumps, control valves and hydraulic tank are located close together to allow for shorter tubes and lines between components reducing friction loss and pressure drops in the lines. The layout further provides greater operator comfort by placing the radiator on the cab side of the upper structure. This allows incoming air to enter the engine compartment from the operator side and hot air and corresponding engine sound to exit on the opposite side away from the operator. This reduces engine compartment heat and sound transmitted to the operator.
Pilot System. The pilot pump is independent from the main pumps and controls the front linkage, swing and travel operations. The pilot control valve operation is proportional to control lever movement delivering outstanding controllability.
Hydraulic Cross Sensing System.
The hydraulic cross sensing system utilizes each of two hydraulic pumps to 100 percent of engine power, under all operating conditions. This improves productivity with faster implement
speeds and quicker, stronger pivot turns.
Boom and Stick Regeneration Circuit.
Boom and stick regeneration circuit saves energy during boom-down and stick-in operation. This increases efficiency, reduces cycle times and pressure loss for higher productivity, lower operating costs and increased fuel efficiency.
Auxiliary Hydraulic Valve. The auxiliary valve is standard on the 336D L. Control Circuits are available as attachments, allowing for operation
of high and medium pressure tools such as shears, grapples, hammers, pulverizers, multi-processors and vibratory plate compactors.
Hydraulic Cylinder Snubbers.
Snubbers are located at the rod-end of the boom cylinders and both ends
of the stick cylinders to cushion shocks while reducing sound levels and extending component life.

Operator Station. The workstation is spacious, quiet and comfortable, assuring high productivity during a long work day. The air conditioner and attachment switches are conveniently located on the right-hand wall, and the key switch and throttle dial are on the right-hand console. The monitor is easy to see and maximizes visibility.
Monitor. The monitor is a full color 400x234 pixels Liquid Crystal Display (LCD) graphic display. The monitor angle is adjustable to minimize sun glare and is capable of displaying information in twenty-seven different languages.
Pre-Start Check. Prior to starting the machine, the system will check for low fluid levels for the engine oil, hydraulic oil and engine coolant and warn the operator through the monitor in the event display area.
Gauge Display. Fuel level, hydraulic oil temperature and coolant temperature are displayed in this area by analog gauges.
Event Display. An icon and the selected language display the machine information in this area.
Multi-information Display. This area is reserved for displaying various forms of operator information. The “CAT” logo is displayed when no information is available to be displayed.
Standard Cab Equipment. To enhance operator comfort and productivity,
the cab includes a lighter, drink holder, coat hook, service meter, literature holder, magazine rack and storage compartment.
Seat. A new optional air suspension seat is available in the 336D L. The standard and optional seats provide a variety of adjustments to suit the operator’s size and weight including fore/aft, height and weight. Wide adjustable armrests and a retractable seat belt are also included.
Joystick Control. Joystick controls have low lever effort and are designed to match the operator’s natural wrist and arm position. The operator can operate joystick controls with an arm on the armrest and the horizontal and vertical strokes have been designed to reduce operator fatigue.
Hydraulic Activation Control Lever.
For added safety, this lever must be in the operate position to activate the machine control functions.
Automatic Climate Control.
Fully automatic climate control adjusts temperature and flow, and determines which air outlet is best in each situation with a touch of a button.
Console. Redesigned consoles feature a simple, functional design to reduce
operator fatigue, ease of switch operation and excellent visibility. Both consoles have attached armrests with height adjustments.
Cab Exterior. The exterior design uses thick steel tubing along the bottom perimeter of the cab, improving the resistance of fatigue and vibration. This design allows the FOGS to be bolted directly to the cab, at the factory or as an attachment later, enabling the machine to meet specifications and job site requirements.
Cab Mounts. The cab shell is attached to the frame with viscous rubber cab mounts, which dampen vibrations and sound levels while enhancing operator comfort.
Windows. All glass is affixed directly to the cab for excellent visibility eliminating window frames. The upper front windshield opens, closes and stores on the roof above the operator with a one-touch action release system.
Wipers. Pillar-mounted wipers increase the operator’s viewing area and offer continuous and intermittent modes.
