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.

Mechanical rotary pump

  • The timing and fuel injection pressures are optimized to maximize performance and fuel economy at a given rated speed.

2-valve cylinder head

  • Cross-flow head design provides excellent breathing from a lower-cost 2-valve cylinder head.

Compact size

  • Horsepower/displacement ratio is best-in-class
  • Lower installed cost
  • Mounting points are the same as previous engine models

Dual frequency

  • 50 Hz/60 Hz dual frequency is available on these engines and meet EPA Interim Tier 4 and EU Stage III A emissions regulations.
