C18 Engine with ACERT™ Technology

Power and reliability

C18

Performing at full-rated net power of 306 kW (410 hp), thelarge displacement and high torque rise allow the D9T toripthrough tough material. Matched to the high-efciency torque converter and electronically controlled power shift transmission, it will provide years of reliable service.

ADEM™ A4 Engine Controller

Manages fuel delivery for optimal performance per liter (gallon) of fuel used. Provides exible fuel mapping, allowing the engine to respond quickly to application needs.Tracksconditions and keeps engine operating at peak efciency.

ATAAC and Airow

Air-to-air aftercooling keeps air intake temperatures down and, in concert with the tight tolerance combustion chamber components, maximizes fuel efciency and minimizes emissions. Signicant improvements in air ow are generated by a water-cooled turbocharger, unique cross-ow head and singleoverhead cam.

Turbocharging and Air-to-Air Aftercooling

Provides high horsepower with faster response time while keeping intake temperatures low for long hours of continuous operation.

Fuel Heater (optional)

Uses the temperature of the engine coolant to warm the cold fuel coming directly from the tank. The fuel heater allows an easier transition to winter blended fuels during season changes.

High Altitude Arrangement (optional)

New with the D9T is an optional high altitude arrangement. The attachment provides an updated turbo and control software that allows full tractor performance up to 4420 m (14,500 ft) altitude.

Cooling System

Durable and efcient

Aluminum Bar Plate Radiator

Cooling system uses a radiator built with rugged, highly efcient aluminum bar plate cores. Thealuminum bar plate construction aids durability and allows for higher heat transfer and superior corrosion resistance.

Hydraulic Air to Oil Cooler

The new air to hydraulic oil cooler reduces hydraulic oil temperatures improving component life. Thecore is built using the same rugged aluminum bar plate design as the jacket water cooler. It is designed in-line with the water cores to minimize debris plugging in allapplications.

Hydraulically Variable, Demand Fan

Provides engine cooling capability that is matched to theambient conditions. In cooler conditions, thefan turnsat a slower speed, reducing power demands. Thisreduces fuel consumption in lower load factor operations. Lowspeed fan operation also reduces both operator andspectator sound levels.

Attachments

• Ultra low speed option for cold weather applications

• Reversing cooling fan forheavy debris applications

Operator Station

Comfort and convenience

The D9T cab is designed and equipped for operator productivity, safety andcomfort. The standard isolation-mounted cab reduces noise and vibration. Overall operator sound levels have been reduced by 2 dB(A). Largewindows, tapered hood, and notched fuel tank provide excellent visibility to all sides of the machine and around the job site.

The D9T comes with an updated in-dash display with new features. An improved Advisor Monitoring System tracks machine operating conditions in real time. Dimmable lights allow the operator to choose between night and day backlight settings, through Advisor, to adjust the brightness of all switches and thekeypad in the cab.

Operators will enjoy comfort features like standard CatComfort Series Seat, adjustable arm rests and automatic climate control. The climate control system automatically adjusts heater and air conditioning controls to maintain a consistent cab temperature throughout the day. Both heater and air conditioner deliver ltered, pressurized, temperature controlled air to the operator and/or windows. Thesystem performs 5 functions: heating, cooling, defrosting, pressurizing and defogging.
