John Deere Power Systems

摘要

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. The PowerTech PWL 4.5L is equipped with an Integrated Emissions Control system consisting of SCR, a diesel oxidation catalyst, and EGR technology. Elimination of the DPF was enabled through combustion system optimization and improvements in SCR system conversion efficiency, Deere Power says.
