Operating data was collected on school bus applications in order to identify what was actually occurring over the course of the school week and the impact it had on the electrical system. Delco Remy high output alternators were installed and compared to other standard industry models. The results were amazing:
- Fuel cost with base high efficiency alternator: $7533*
- Fuel cost savings with efficiency alternator: $1507*
* Based on $4 / gal diesel fuel cost and 250k mi
While the power demands of the alternator are generally small in comparison to the overall vehicle, the impact on fuel cost is remarkable. Bottom line: Increasing alternator efficiency can, and will, measurably reduce fuel costs.
