Noise, Vibration And Harshness (NVH)

• The deep-skirt block design, case hardening of the block, one-piece aluminum crankcase and one-piece aluminum bellhousing help reduce NVH.
   
   
• In addition to structural improvements, the Bosch electrically controlled common rail fuel injection system allows full authority in injection timing and quantity to help manage NVH.
   
   

  A small charge of fuel (the "pilot injection") enters the cylinder, followed by a slight delay before the main pulse of fuel is injected.
   
   

  This charge produces a combustion process that builds gradually for quieter, smoother acceleration.
   
   

  The complete electrically controlled fuel injection process can tune the fuel injection pulses for NVH optimization not previously seen on a full-size pickup engine.
