By putting its new hybrid electric power systems into production, Eaton offers fleet owners a substantial fuel savings, quieter vehicle operation and reduced emissions, cutting the constructionindustry's carbon footprint and dependence on petroleum-based fuels. Hybrid electric power systems also provide engine-off PTO capability for operators needing worksite hydraulic functions and an auxiliary electric power source. As showcased on a Class 7 Kenworth T300 hybrid truck prototype, Eaton's electric propulsion system includes an UltraShift transmission, motor generator, two lithium-ion batteries and electronic controls.
