AGCO SISU POWER 84 CWA-4V Engine Features:

  • Four-valve-per-cylinder cross-flow head permits our engineers to center the injector over the piston, improving fuel/air mixing to better control emissions and fuel consumption
  • Bosch common-rail fuel injection system takes its commands from the EEM3 electronic engine management software for precise, faster response and more power per gallon of diesel
  • Dual centrally supported cylinder liners eliminate liner cavitation, prolonging cylinder life
  • Lightweight, big-end connecting rods’ fracture-split production process leaves a rough edge at the face to improve holding power and durability while minimizing vibration. SISU POWER 84 CWA-4V features e³ SCR (Selective Catalytic Reduction) clean air technology optimized for high performance, low particulate emissions and lower fuel consumption (meets Tier IV interim standards). 24-gallon Polyethylene tank holds AdBlue and is filled after every three fuel fill-ups
