Features

Expand All Collapse All

2-valve cylinder head

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

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 1600 bar (23,000 PSI). It also controls fuel injection timing and provides precise control for the start, duration, and end of the injection

Fixed geometry turbocharger

  • Fixed geometry turbochargers are precisely matched to the power level and application

Turbocharged

  • In turbocharged engines, the air is pre-compressed. Due to the higher pressure, more air is supplied into the combustion chamber allowing a corresponding increase in fuel injection which results in greater engine output

Multiple injection strategy

  • The new HPCR fuel system and engine control unit (ECU) allow for multiple fuel injections. The number of fuel injections, based on speed and load, help contribute to lower combustion temperatures, which reduce the formation of NOx and particulates. The multiple injection strategy also provides an added benefit of noise reduction

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.

Compact size

  • Mounting points are the same as Tier 2/Stage II engine models

Engine performance

  • Block loading capability provided with standard electronic governor control

Additional features

  • Self-adjusting poly-vee fan drive
  • Forged-steel connecting rods
  • Replaceable wet-type cylinder liners
  • Either-side service
  • 500-hour oil change
