PowerTech PVL 6.8L engines provide more power and fluid economy for gen-set applications. The PowerTech PVL technology platform includes series turbochargers for improved performance and an Integrated Emissions Control system that consists of cooled EGR and DOC/SCR.
These engines use diesel oxidation catalyst (DOC) and selective catalaytic reduction (SCR) technology to meet Final Tier 4 emission regulations. They meet customer performance without the need for a diesel particulate filter (DPF).
Heavy-duty components that are usually found in our larger engines are used throughout our generator drive engine line. Many of our DOC/SCR engines feature top-liner cooling, steel pistons, and variable-speed fan drives.
Varies exhaust pressure based on load and speed to ensure proper EGR flow. The combination of the cooled EGR and VGT provide low-speed torque, quicker transient response, higher-peak torque, and world-class fuel economy.
The HPCR fuel system provides variable common-rail pressure, multiple injections, and higher injection pressures up to 2,500 bar (36,000 psi). It also controls fuel injection timing and provides precise control for the start, duration, and end of injection.
This is the most efficient method of cooling intake air to help reduce engine emissions while maintaining low-speed torque, transient response time, and peak torque. It enables an engine to meet emissions regulations with better fuel economy and the lowest installed costs.
From the day your gen-set begins operation, it's warranted for uninterrupted service. We offer a 2-Year/2,000-Hour and 1-Year/Unlimited-Hour Warranty. In addition, extended warranties are available under certain conditions. Be sure to register your engine for warranty support at JohnDeere.com/enginewarranty.
