Features

Expand All Collapse All

Fixed geometry turbocharger

  • Fixed geometry turbochargers are sized for a specific power range and optimized to provide excellent performance across the entire torque curve. They are also designed to maximize fuel economy between the engine’s rated speed and peak torque.

High-pressure common-rail (HPCR) and engine control unit (ECU)

  • The HPCR fuel system provides variable common rail pressure, multiple injections, and higher injection pressures, up to 1,600 bar (23,000 psi). It also controls fuel injection timing and provides precise control for the start, duration, and end of injection.

2-valve cylinder head

  • Cross-flow head design provides excellent breathing from a lower-cost 2-valve cylinder head

Air-to-air aftercooled

  • This is the most efficient method of cooling intake air to help reduce engine emissions while maintaining low-speed torque, transient response time, and peak torque. It enables an engine to meet emissions regulations with better fuel economy and the lowest installed costs

Compact size

  • Horsepower/displacement ratio is best-in-class
  • Lower installed cost
  • Mounting points are the same as previous engine models

John Deere electronic engine controls

  • Electronic engine controls monitor critical engine functions, providing warning and/or shutdown to prevent costly repairs and eliminate the need for add-on governing components, all lowering total installed costs.

Dual frequency

  • 50 Hz/60 Hz dual frequency is available on these engines and meet EPA Interim Tier 3 and EU Stage III A emissions regulations.

Additional features

  • Self-adjusting poly-vee fan drive
  • Forged-steel connecting rods
  • Replaceable wet-type cylinder liners
  • Either-side service
  • Gear Driven Auxiliary Drive
