Expand AllWastegated turbocharger
- Wastegated turbochargers are designed to develop more airflow at lower engine speeds to improve low-speed torque. The wastegate control device bleeds off a portion of the exhaust flow at higher engine speeds. Wastegated turbos deliver improved transient response and higher peak torque without compromising engine envelope size. They also provide the lowest installed cost across a given power range.
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
