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 flexibility ofhydraulically controlled unit fuelinjection. The system excels in itsability to control injection pressure overthe entire 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 berouted around the turbocharger to theexhaust piping to prevent wheel spinoverspeed at high rpm but low loadconditions.

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 top tankto remove.

Serviceability. This modular coredesign permits removal of a single corewithout removing the entire radiator sorepair costs and downtime are reduced.The top tank, side channels and onesealing surface makes AMOCS morereliable and easier to service. A sitegauge allows 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 isavailable as an option to deflect thedamaging debris the engine fan propelsat the 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), the demandfan performance converges towardsthat of the standard fan so lesser benefitis achieved.
