Features

Series turbocharger

  • Air is first drawn into the low-pressure turbocharger and compressed to a higher pressure. The compressed air is then drawn into the high-pressure turbocharger, where the air is further compressed. The high-pressure air is then routed through a charge air cooler and into the engine's intake manifold. By splitting the work between two turbochargers, both can operate at peak efficiency and at slower rotating speeds — lowering stress on turbocharger components and improving reliability. Series turbocharging delivers more boost pressure than single turbocharger configurations, which results in higher power density, improved low-speed torque, and improved high altitude operation.

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.

Selective catalytic reduction (SCR)

  • John Deere engines feature an SCR system that utilizes a urea-based additive, sometimes referred to as diesel exhaust fluid (DEF) to meet Stage IV emission standards. A chemical reaction in the SCR catalyst converts urea and NOx emissions into nitrogen and water vapor.

High-pressure common-rail (HPCR)

  • The HPCR fuel system provides variable common-rail pressure and high injection pressures. It also controls fuel injection timing and provides precise control for the start, duration, and end of injection.

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.

4-valve cylinder head

  • The 4-valve cylinder head provides excellent airflow resulting in excellent low-speed torque and transient response.

Compact size

  • Lower installed cost
  • Engine mounting strategy consistent with previous engine models

John Deere electronic engine controls

  • Faster engine control unit (ECU) manages both the engine and the exhaust filter
  • Premium software integrates with equipment or vehicles to reduce engineering and installation costs
