RATED BHP is the power rating for variable speed and loadapplications where full power is required intermittently.

CONTINUOUS BHP is the power rating for applications operatingunder a constant load and speed for long periods of time.

HEAVY DUTY - see application ratings/definitions, engineperformance curves.

POWER OUTPUT is withing + or - 5% at standard SAE J 1995 andISO 3046.

DIMENSIONS

FEATURES AND BENEFITSVariable Geometry Turbocharger (VGT)• Varies exhaust pressure based on load and speed to insure

proper EGR flow; greater low-speed torque, quicker transientresponse, higher peak torque, and best-in-class fuel economy.

Cooled Exhaust Gas Recirculation (EGR)• Cools and mixes measured amounts of cooled exhaust gas with

incoming fresh air to lower peak combustion temperatures,thereby reducing NOx.

4-Valve Cylinder Head• Provides excellent airflow resulting in greater low speed

torque and better transient response. Cross flow design.Air-to-Air Intercooling• Most efficient method of cooling intake air to help reduce

engine emissions while maintaining low speed torque,transient response time and peak torque. Enables an engine tomeet emissions with better fuel economy and the lowestinstalled costs

High Pressure Electronic Fuel Injection Systems• HPCR: Higher injection pressures, up to 1600 bar

(23,500 PSI), variable injection pressure, variable timingcontrol, multiple injections and controls the duration ofinjection.

Compact Size• Horsepower/displacement ratio is best-in-class (lower installed

cost)• Mounting points for Tier 3/Stage III A engine models same

as Tier 2/Stage 2 engine models

John Deere Electronic Engine Controls• Monitors critical engine functions providing warning and/or

shutdown to prevent costly engine repairs; eliminates need foradd-on governing components; all lowering total installedcosts. Snapshot diagnostic data that can be retrieved usingcommonly available diagnostic service tools• New common wiring interface connector for vehicles oravailable OEM instrumentation packages; new solid conduitand "T" connectors to reduce wiring stress, greater durabilityand improved appearance

• Factory installed engine mounted ECU or remote mountedECU, wiring harness and associated components

• Industry standard SAE J1939 interface which communicateswith other vehicle systems, eliminating redundant sensors andreducing vehicle installed cost

Engine Performance• New 'power bulge' feature• Multiple rated speeds to further reduce noise and improve

fuel economy• New higher peak torque ratings• Better transient response time• Greater levels of low speed torqueAdditional Features• Glow plugs; gear-driven auxiliary drive; optional 500-hour

oil change; self adjusting ploy-vee fan drive, R.H. and L.H.engine mounted fuel filters; engine mounted ECU
