John Deere 4045HFG85 4.5L Generator Drive Engine

Model Photo

4045HFG85

  • PowerTech™ Plus
  • Standby: 147 kW (197 hp) @ 1800 rpm
  • Prime: 134 kW (180 hp) @ 1800 rpm
  • Jet fuel capable

 

Features

Jet fuel capable

  • The 4-valve cylinder head provides excellent airflow. Cross flow design

4-valve cylinder head

  • The 4-valve cylinder head provides excellent airflow. Cross flow design

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

Cooled exhaust gas recirculation (EGR)

  • EGR cools and mixes measured amounts of cooled exhaust gas with incoming fresh air to lower peak combustion temperatures, thereby reducing NOx

Variable geometry turbocharger (VGT)

  • Varies exhaust pressure based on load and speed to ensure proper EGR flow; greater low-speed 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

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 Tier 2/Stage II engine models

John Deere electronic engine controls

  • Electronic engine controls monitor 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

Additional features

  • Self-adjusting poly-vee fan drive
