Tips For Fleet Fuel Efficiency
By slightly over-spec’ing engines in order to run more consistently in the “sweet spot,” choosing a gear ratio low enough to suit a fleet’s application and location, and enabling the correct fuel-efficient, engine-specific parameters, fuel economy will improve by aroundÂ five percent.
PHH FirstFleet offered the following list for achieving better fuel economy:
- Increase engine torque ratingsÂ - Increase torque ratings to decrease time spent in the high output torque ranges.
- Decrease gear ratioÂ - Choose a lower gear ratio to improve fuel economy.
- Stop SpeedingÂ - Above 70 MPH, a tractor’s engine works to overcome aerodynamic drag.
- IdlingÂ - Idling uses .5 to 1 gallon of fuel per hour.
- Progressive Shifting – Drivers shifting quickly in lower gears prevents over-revving, which decreases fuel consumption.
- Spec APUsÂ - Auxiliary Power Units allow drivers to run peripheral applications without running the engine.Â
- Aerodynamics – New innovations in trailer aerodynamics decrease wind resistance.
- Lower WeightÂ - New low weight materials allow for more potential fuel economy gains.
- Low Profile Radial or Wide Based TiresÂ - Research indicates that fuel economy can improve as much asÂ two percentÂ toÂ five percentÂ by using low profile and/or wide based tires and wheels.Â
Wal-Mart used some of these same techniques to increase the fuel efficiency of itsÂ fleet by about 15 percent.
