John Deere PowerTech PWL T4-F technology.

The 85- to 140-horsepower PowerTech PWL 4.5L engine, which will meet Tier 4-Final regulations without a DPF, complements the John Deere lineup of Tier 4-Final off-highway diesel engines rated from 48 horsepower to 600 horsepower, announced earlier.

Cummins QSF3.8 engine, with horsepower ratings from 85 to 132, meets EPA Tier 4-Final regulations with a minimum of exhaust aftertreatment.

JCB Ecomax diesels meet Tier 4-I requirements without external aftertreatment or DPFs

Three John Deere Power Systems models—the PowerTech PWX 4.5L and PVX 4.5L engines, and the PowerTech PVX 6.8L model below 174 horsepower— are now certified as compliant with U.S. EPA emissions regulations.

Thanks to development worth about $122 million, JCB’s Ecomax diesels won’t need a DPF to meet Tier 4 Interim limits.
