Proposal for Fielding a Fleet of Refuse Trucks with the Parallel Hybrid Hydraulic Eaton HLA® System
| Sub-Grantees: | Eaton Corporation
|
The Eaton HLA system is a parallel hybrid hydraulic regenerative braking system. It converts energy normally lost during braking and stores it in the form of high-pressure hydraulic fluid. This fluid is then used to provide a positive torque to the driveline in a subsequent acceleration event. The HLA system has demonstrated 19-28% better fuel economy in refuse applications.
Hybrid drivetrains have shown the ability to simultaneously reduced fuel consumption and exhaust emissions. In the heavy-duty refuse trucks on which this project would be focused, the hybrid hydraulic system would allow the vehicle’s engines to operate in regimes of high NOx creation by reducing the engine loading (fuel economy mode) or limiting the time in which the engine is at maximum output (performance mode) or a combination of the two. It is anticipated that the NOx reductions will be 25% or greater.
Under this program, waste collection companies or municipalities would purchase new Peterbilt 320 chassis, refuse compaction bodies, and other equipment normally on their refuse trucks. The incremental cost of hybridization would be paid for under the proposal funding. In other words, the end user gets a hybrid refuse truck for the cost of a standard, non-hybrid refuse truck. At the end of the roughly one year test period, the hybrid systems would be removed and returned to Eaton for evaluation. The end user has the option to return the refuse truck to its non-hybrid configuration or have a production HLA system installed in the vehicle at a discounted cost.
