4045TF285

Industrial Marine Engine
  • 4.5L PowerTech™
  • 71 kW (95 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.

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 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
  • Power bulge feature

  • Increased low-speed torque

  • Higher-peak torque ratings
