With available power ratings from 125 to 173 horsepower, John Deere Power Systems has introduced a new 4.5-liter Tier 4 Final industrial engine in the PowerTech PSL.

Engineered for OEM customers, the PowerTech PSL 4.5L meets emissions requirements through a combination of cooled exhaust gas recirculation (EGR), a diesel oxidization catalyst (DOC) and selective catalytic reduction (SCR).

John Deere calls this an Integrated Emissions Control system and it is also featured on the company’s 85 to 140 hp PWL 4.5L engine. The company also offers a 4.5L engine with a diesel particulate filter (DPF) in the PowerTech PSS.
