John Deere Construction & Forestry has finally announced its T4-F technology path, incorporating selective catalytic reduction (SCR) into its engine configurations.

To meet T4-F emissions regulations in some power categories, John Deere has developed the "Integrated Emissions Control" system — an optimized aftertreatment solution paired with the company's chosen T4-I engine platform that features cooled exhaust gas recirculation (EGR). The John Deere Integrated Emissions Control system will typically consist of a diesel oxidation catalyst (DOC), diesel particulate filter (DPF) and an SCR system designed to meet the demands of off-highway applications. John Deere will continue to tailor its Integrated Emissions Control system configurations to fit a variety of off-highway applications.

 

Consisting of an exhaust filter and SCR aftertreatment components that are optimized and fully integrated, the Integrated Emissions Control system will allow John Deere engines to utilize less diesel exhaust fluid (DEF) than alternative T4-I SCR technology solutions, according to the company. Lower DEF consumption means DEF tank size can be smaller — minimizing the impact on vehicle applications, extending DEF filter service intervals, and reducing operator involvement.
