The engines are fully compliant with the EPA’s Final Tier 4 emissions standard.
HIPOWER SYSTEMS has announced it has chosen John Deere as a supplier for Final Tier 4 diesel engines in HIPOWER generators. The first engine HIPOWER will be offering in its generators is the John Deere PowerTech™ PSS 9.0L.
The engines are fully compliant with the EPA’s Final Tier 4 emissions standard, which is part of a federally mandated effort to reduce emissions of particulate matter (PM), oxides of nitrogen (NOx), and other air pollutants from new, non-road diesel engines. Final phase of the standard is ongoing through 2015.
