Bexar County’s Kenworth T370 hybrids are powered by PACCAR PX-6 engines rated at 260hp and 620 lb-ft of torque, and the Eaton diesel-electric hybrid power system. The trucks use an integral transmission-mounted motor/generator; frame-mounted 340-volt, lithium-ion battery pack; and dedicated power management system. The power takeoff (PTO) for the dump is run off the main engine.
Electricity generated through regenerative braking is stored and used for acceleration, assisting the diesel engine. The hybrid system is monitored through an in-dash display. As the power requirements for different driving conditions change, the screen constantly updates the driver on system status.
