Ecomax Tier 4 Final Engines

Building on the JCB Ecomax T4i engine, the Ecomax T4F range will meet Tier 4 Final emissions regulations by using a compact selective catalytic reduction (SCR) system with a urea-based additive for NOx reduction in engines above 74 hp.

  • Deliver up to a 5% fuel efficiency improvement
  • Easy installation into existing machinery
  • Single exhaust muffler
  • Use a 2% to 3% ratio of exhaust additive to fuel
  • Space-efficient mixing system for the SCR offers a reduced exhaust flow distance between the engine and catalyst
  • Designed to allow JCB dealers to de-tier engines for sale of used equipment in less regulated territories
