Cummins Engine LogoEquipped to Take on Any Job

Every Cummins engine is built using the following features:


    Near-Zero Emissions from the integrated aftertreatment system combining cooled EGR with proven Selective Catalytic Reduction (SCR) technology

  • The Cummins VGT™ Turbocharger — Electric actuation through a sliding-nozzle design means you can adjust the turbo to deliver precisely the boost you need to respond to variable engine loads

  • Low Operating Cost through reduced maintenance and long service intervals

  • Cooled EGR (Exhaust Gas Recirculation) — next-generation system that lowers combustion temperatures, reducing emissions and optimizing fuel economy

  • Cummins Aftertreatment System — By minimizing particulate matter, it meets emissions requirements while maintaining high performance, reliability and durability.
