This 9.0L, 6-cylinder engine, meets emissions requirements without sacrificing performance. New features include cooled exhaust gas recirculation, variable geometry turbocharger, 4-valve cylinder heads, and a high-pressure common rail fuel system. Power ratings, fuel economy, torque levels, transient response time, and other features meet or exceed Tier 2/Stage II.

Features & Benefits
Variable Geometry Turbocharger (VGT)
Varies exhaust pressure based on load and speed to insure proper EGR flow; greater low-speed torque, quicker transient response, higher peak torque, and best-in-class fuel economy
Cooled EGR - Exhaust Gas Recirculation
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. U-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 to meet emissions with better fuel economy and the lowest installed costs
High Pressure Electronic Fuel Injection Systems
HPCR: Higher injection pressures, up to 1600 bar (23,500 PSI) variable injection pressure, variable timing control, multiple injections and controls the duration of injection
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 for add-on governing components; all lowering total installed costs. Snapshot diagnostic data that can be retrieved using commonly available diagnostic service tools New common wiring interface connector for vehicles or available OEM instrumentation packages; new solid conduit and "T" connectors to reduce wiring stress, greater durability and improved appearance Factory installed engine mounted ECU or remote mounted ECU, wiring harness and associated components Industry standard SAE J1939 interface which communicates with other vehicle systems, eliminating redundant sensors and reducing vehicle installed cost
Engine Performance
Multiple rated speeds to further reduce noise and improve fuel economy New higher peak torque ratings Higher levels of power bulge Better transient response time Greater levels of low speed torque
Additional features
Single-piece low friction piston; directed top-liner cooling; gear-driven auxiliary drive; optional 500-hour oil change; self-adjusting poly-vee fan drive; optional rear PTO; engine mounted ECU
