John Deere Power Systems has introduced the PowerTech PWL 4.5L engine that will meet Tier 4 Final/Stage IV emissions regulations without a diesel particulate filter (DPF). The 56- to 104-kW (75- to 140-hp) engine complements Deere’s previously announced lineup of Tier 4 Final/Stage IV off-highway diesel engines rated 36 to 448 kW (48 to 600 hp). The PowerTech PWL 4.5L is equipped with an Integrated Emissions Control system consisting of selective catalytic reduction (SCR), a diesel oxidation catalyst (DOC), and cooled exhaust gas recirculation (EGR) technology. Elimination of the DPF was enabled through combustion system optimization and improvements in SCR system conversion efficiency. Diesel exhaust fluid (DEF) consumption with Deere’s Tier 4 Final/Stage IV engines will be 1 to 4% of diesel fuel consumption, depending on the application. The engines will provide the same or higher levels of power density and transient response as the Interim Tier 4/Stage III B product lineup.
