John Deere 4045TF285 4.5L Industrial Diesel Engine

Model Photo

4045TF285

  • PowerTech™
  • 63 - 74 kW (84 - 99 hp)

 

Features

2-valve cylinder head

  • Cross flow head design that provides excellent breathing from a lower cost two-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 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.

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

  • PowerTech E engines offer electronically controlled fuel systems with improved cold-start performance, precise engine speed control, torque curve shaping and more. Because these systems have less need for redundant sensors, add-on electronic governors, and shutdown devices - they result in a lower total installed cost.

Engine performance

  • New power bulge feature
  • Increased low-speed torque
  • New higher-peak torque ratings
  • Faster torque rise
  • Lower-rated speeds available for reduced noise and improved fuel economy

Compact size

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

Additional features

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