  • 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.

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

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

  • Horsepower/displacement ratio is best-in-class

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