A combination of innovations working at the point of combustion, ACERT Technologyoptimizes engine performance while meeting emission regulations for off-road applications.

Engine

ADEM™ A4 Engine Controller. The air-cooled ADEM A4 controller is the brainof the engine and contains the engine’scontrol software. It regulates fueldelivery, airflow and other enginefunctions. In addition, it directs theHEUI injectors to deliver multipleinjections of fuel during the engine’scompression stroke.

Fuel Delivery. Multiple injection fueldelivery involves a high degree ofprecision. Precisely controlling thecombustion cycle lowers combustionchamber temperatures, which lowersemissions and optimizes fuel economy.This translates into more work outputper unit of fuel.

HEUI™ Fuel System. The HEUI fuelsystem is highly evolved, with a provenrecord of reliability. HEUI uses thetechnical advancement of an electroniccontrol system with the flexibilityof hydraulically controlled unit fuelinjection. The system excels in its abilityto control injection pressure over theentire engine operating speed range.These features allow the C9 to havecomplete control over injection timing,duration, and pressure.

Air-to-Air Aftercooler. The air-to-airaftercooler (ATAAC) brings cool airto the engine which increases life andlowers emissions. In addition, theATAAC, together with the tight tolerancecombustion chamber components,maximizes fuel efficiency.

Wastegate Turbocharger. The wastegateallows high-volume exhaust to be routedaround the turbocharger to the exhaustpiping to prevent wheel spin overspeedat high rpm but low load conditions.

Service. The new C9 engine offerseasier maintenance and repair throughmonitoring key functions and loggingcritical indicators. Electronic diagnosticaccess is possible with a single tool,the Cat Electronic Technician.

Next Generation Modular Radiator(NGMR). Improves cooling capabilitiesby using a parallel flow system withsix cores. Serviceability is improvedwith NGMR since there is no toptank to remove.

Serviceability. This modular core designpermits removal of a single core withoutremoving the entire radiator so repaircosts and downtime are reduced. The toptank, side channels and one sealingsurface makes NGMR more reliableand easier to service. A site gaugeallows for quick service checks.

Leak Protection. To reduce the potentialfor coolant leaks, brass tubes are weldedto a large, thick header to improve thestrength of the tube-to-header joint.In conditions where abrasive materialscan be airborne, the attachment sandblast grid should be used to preventcore damage.

Sand Blast Grid. In an applicationwhere airborne debris is prevalent,radiator core protection is a concern.To extend radiator life in harshapplications, a sand blast grid is availableas an option to deflect the damagingdebris the engine fan propels atthe radiator.

Demand Fan Option. Based primarilyon ambient air temperature, the optionaldemand fan can improve productivityup to three percent and reduce fuelconsumption up to four percent sincethe demand fan will only run at a speedneeded to meet the cooling requirementsof the machine. As cooling requirementsincrease above 24° C (75° F), thedemand fan performance convergestowards that of the standard fan solesser benefit is achieved.

Torque Divider. A single-stage torquedivider sends 70 percent of enginetorque through a converter and30 percent through a direct drive shaftfor greater driveline efficiency andhigher torque multiplication.

The D6R Series 3 torque dividerprovides:

• High reliability

• Low dynamic torque

• Optimum combination of operatorefficiency and driveline reliability

• Components designed to absorbfull engine power

Operating Efficiency and DrivelineReliability. The D6R Series 3 torquedivider attains the best combinationof operating efficiency and drivelinereliability. It acts as a hydrodynamiccomponent between the engine andtransmission to reduce dozing shockloads to the transmission and final drives.

Planetary Power Shift Transmission.The D6R Series 3 planetary powershift transmission includes three speedsforward and three speeds reverse andutilizes large diameter, high capacity,oil-cooled clutches. These clutchesprovide higher torque capacity andincreased service life. The planetarypower shift transmission offers severalkey features and benefits, including:

• Electronically controlled modulationsystem that allows fast, smoothspeed and direction changes

• Modular transmission and differentialslide into rear case for servicingease, even when a ripper is installed

Differential Steering System.Differential steering maintains powerto both tracks while turning. The tractorturns when one track speeds up and theother slows down an equal amount.The operator can steer and control thetransmission simultaneously, which canreduce cycle times in some applications.The differential steering tiller bar hastouch shift buttons for upshifts anddownshifts. The tiller bar itself is easilyrotated forward or reverse to change therespective tractor direction. It is movedforward to steer the tractor to the left andpulled back to move right. Low tillerbar efforts assure operator comfortduring long shifts. Large blade loadscan be maneuvered around buildings,bridge abutments, trees or other obstacles.Steering modulation is also optimizedfor precise control in these applications.Greater load capacity, power and speedcontrol are possible in soft underfootconditions on steep slopes because bothtracks are powered during turns.

Elevated Final Drive. Elevated finaldrives are isolated from ground andwork tool-induced impact loads forextended power train life. The modulardesign ensures quick and easy servicewhen required.

Load Compensating Shifting.With load compensating shifting,clutch engagement timing automaticallyadjusts according to the load factor.This allows improved tractor performanceand operator comfort during speedchanges and reduces the amount ofenergy dissipated through the clutchesto help extend transmissioncomponent life.

Multi Velocity Program (MVP).The Multi Velocity Program (MVP) isan innovative machine control systemthat allows the operator to choose fromfive different speed ranges in Forwardand Reverse, providing the operatorwith the flexibility to match machinespeed to a variety of applications andground conditions. This exclusivesolution allows the operator to maximizeproduction, minimize fuel consumption,and lower overall machine operatingcosts. MVP provides the operator withfive speed ranges in both Forward andReverse. The engine speed in each speedrange has been optimized to provide thebest performance, fuel economy, anddrawbar pull. The operator retains theability to operate the machine in eitherthe 3 speed or 5 speed mode.
