C32 Engine. Performing at full rated net power of 634 kW (850 hp) at 1,800 rpm with a high torque rise of 21 percent, the large displacement and high torque allow the D11T to doze through tough material. Matched to the high efficiency torque divider and electronically controlled power shift transmission, it will provide years of dependable service.
C32 Block. The block features a design that adds structural strength through compaction and thicker walls. This design supports the engine’s higher compression ratios.
Overhead Cams. Two, single (one per head) overhead cams are driven by gears on the flywheel end of the engine. Placing the cam gears at the flywheel end significantly reduces noise and vibration. To reduce wear, two pendulum absorbers are mounted at the front of the camshafts. Together, these two features contribute to the long-life and durability of this engine.
ADEM™ A4 Engine Controller.
The ADEM A4 electronic control module manages fuel delivery and air flow to get the best performance per gallon (liter) of fuel used. It provides flexible fuel mapping, allowing the engine to respond quickly to varying application needs. It keeps track of engine and machine conditions while keeping the engine operating at peak efficiency.
Fuel Delivery. 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; translating into more work output for your fuel used.

MEUI Fuel System. A highly evolved fuel
system with a proven record of reliability in the field. MEUI combines the technical advancement of an electronic control system with the simplicity of direct mechanically controlled unit fuel injection. The MEUI system excels in its ability to control injection pressure over the entire engine operating speed range. These features allow the C32 to have complete control over injection timing, duration, and pressure.
ATAAC and Airflow. Air-to-air aftercooling keeps air intake temperatures down and, in concert with the tight tolerance combustion chamber components, maximizes fuel efficiency and minimizes emissions. Significant improvements in air flow are generated by water-cooled turbochargers, unique cross-flow head, single rear-driven overhead cams, and a more efficient intake manifold.
Engine maintenance and repair.
Is easier through monitoring key functions and logging critical indicators. Electronic diagnostic access is possible with the Electronic Technician (Cat ET).
Aluminum Spacer. Located between the block and head to eliminate the need for block counterbores, and extend block life.
Hardened-faced valves. Through­hardened crankshaft journals and steel­backed, copper-bonded aluminum bearings, help assure reliable performance in the toughest duty.
Components have longer life. Because oil-cooled pistons and full-length, water­cooled cylinder liners provide maximum heat transfer. The cylinder heads also utilize additional coolant passages to provide maximum cooling to the engine.

Two-pass cooling system. Using a two-pass system, the AMOCS radiator provides a more efficient heat exchange. The coolant is routed from a sectioned bottom tank up the front side, over the top of the core, and down the engine side of the core to the bottom tank. This flow pattern allows the coolant to pass through the radiator twice for better cooling.
Modular Design. The cooling elements are individual core modules connected to a sectioned bottom tank. There is no top tank to remove.
Standard 9.4 steel fins per 2.54 cm (1 in), or an optional 6 steel fins per
2.54 cm (1 in)
Brass tube construction within each core for improved reliability
Hydraulically Variable, Demand Fan.
The hydraulically driven 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 frees up more power in high load factor operations or reduces fuel consumption in lower load factor operations. Low speed fan operation also reduces both operator and spectator sound levels. The ADEM A4 engine controller regulates the fan speed through a variable displacement pump. An attachment low speed option is available for cold weather operations to avoid over cooling the engine.
Easy Serviceability.
Servicing of the AMOCS can be performed without tilting the radiator guard
No need to remove or replace a major component as on single-core radiators
Each core module can be replaced individually (without removing the entire radiator), saving considerable cost and repair time

Dozer Control Lever. A low-effort electronic dozer control handle gives the operator control of all dozer functions with one hand. Fore/aft movement of the lever lowers and raises the blade. Left/right movement directionally tilts the blade.
The thumb lever at the top of the handle, controls blade pitch fore and aft. The trigger switch pitches the blade forward to dump the load.
The two thumb buttons to the left of the implement control provide control over the semi-automated blade pitch functions that Dual Tilt provides. Blade pitch for load, carry and spread segments can be preset on Advisor and controlled by the buttons. The left side button cycles between the pitch settings for each segment of the push cycle. The right side button cancels out of the pitch functions without losing the preset pitch angles. This Auto Blade Assist (ABA) feature is turned on and off using a switch on the right side console.
Computer Aided Earthmoving System (CAES) (optional). Computer Aided
Earthmoving Systems (CAES) replace conventional surveying with advanced GPS and radio communications equipment, improving operator’s accuracy and efficiency. CAES can communicate back and forth with the office and access site design plans. Office software can generate designs on the fly and provide customized production and design reports. CAES gives operators continuous, interactive access to machine and operating information right in the cab – so they have the tools they need to operate with more precision and predictability. An in-cab display gives operators easy-to-understand color diagrams of where to cut and fill. With CAES, the effort of reading maps or looking for grade stakes is virtually eliminated. And because it gives immediate, accurate feedback, operators can doze quickly, accurately and confidently. CAES helps identify ways to reduce errors and constantly improve the production process – ultimately helping reduce cost.
AutoCarry (optional). AutoCarry provides automatic blade control (raise and lower only) during the carry segment of the dozing cycle. Drawbar pull, ground speed, track slip, and machine attitude are integrated to control track slip and maintain optimal blade loads. AutoCarry is intended to enhance the operator’s productivity in high production earthmoving with carry distances over
30.5 m (100 ft). By monitoring ground speed with the belly-mounted radar gun, the auto carry system controls blade load to maintain approximately 2.4 km/h (1.5 mph) true ground speed. Track slip is monitored and limited to under 16%. Readouts of the true ground speed and track slip are available in the AutoCarry menu on Advisor. Through the system’s Dynamic Inclination Sensor (DIS), readouts of the tractor pitch angle and side-to-side scope are also available on Advisor.
Ripper Control Lever. A rigidly mounted handgrip provides firm support for the operator even when ripping in the roughest terrain. The low effort thumb lever controls raising and lowering. The finger lever controls shank-in and shank-out positioning. The thumb button automatically raises the ripper.
Finger Tip Controls (FTC). Clustered for easy, one-hand operation to the operator’s left. They control steering, machine direction and gear selection.
Electronic Clutch and Brake (ECB) steering System – consists of two small levers that send signals that control the steering valve. Levers require less than three pounds of pull to actuate. Steering is accomplished in much the same way as traditional clutch and brake arrangements, but with less time and effort.
