VOLVO FLYWHEEL BUS

The concept of energy recuperation, based on a hydraulic pressure accumulator system in conjunction with hydrostatic transmission, is being used in a Volvo bus development. Using flywheel energy recuperation, the diesel power unit/flywheel/hydraulics pack supplies a hydraulic motor and conventional transmission and is fitted in a rear-mounted underfloor location on a 12 M bus chassis. The driving modes consist of normal operation using the diesel engine only in an optimised speed range with the flywheel at rest; the second mode uses diesel engine and flywheel for acceleration; the third mode on flywheel energy only enables the vehicle to cover short distances with the diesel engine switched off. The transmission offers smooth acceleration as well as corresponding jerk-free retardation combined with fuel savings of 15-25% and environmental benefits. (TRRL)
