John Deere Power Systems introduced its PowerTech PWL 4.5L Tier 4 Final engine at Bauma 2013 today.
The engine meets Tier 4 Final regulations without a diesel particulate filter (DPF).
The PowerTech PWL 4.5L is rated at 85 horsepower to 140 horsepower and performs applications in the 75 horsepower to 140 horsepower segment without the use of a diesel particulate filter (DPF).
Instead of a DPF, the engine uses an Integrated Emissions Control system configured with selective catalytic reduction (SCR), a diesel oxidation catalyst (DOC) and cooled exhaust gas recirculation (EGR) technology.
