Features & Benefits

  • Designed and developed based on FEV technology platform.
  • Built upon the proven durability of YC6G series engines, while inheriting all the super advantages.
  • They share main components and parts with YC6G series diesels, making replacement parts easier to access.
  • Forged crankshaft and dry sleeve liners-Improve engine reliability greatly.
  • Crankshaft damper pulleys-Effectively improve reliability by reducing torsional vibration of the crankshaft.
  • Dual-balance shaft unit-Diminish the vibration generated by the piston’s movement.
  • HONEYWELL turbocharger equipped with by-pass valve -Deliver quick response and higher performance.
