Thanks to development worth about $122 million, JCB’s Ecomax diesels won’t need a DPF to meet Tier 4 Interim limits. Twin Vortex combustion design jointly developed with Ricardo, and electronic controls from Delphi, are among new features. Its 4.4-liter and 4.8-liter model will use cooled EGR and second-generation common-rail high-pressure fuel injection.
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’s 3CX and 4CX backhoe loaders now come standard with the company’s Tier 4-Interim Ecomax diesel engines, delivering up to 9 percent better fuel consumption and a 6 percent boost in torque, the company says.
