Heavy Duty Alternator

Fuel Economy Calculator

Increasing alternator efficiency can, and will measurably reduce diesel fuel costs.  Electrical power on a heavy duty truck is not free.  It comes as a direct result of consuming fuel within the engine to drive the alternator.  High efficiency alternators translate to less engine horsepower requirements, resulting in substantial fuel savings for the fleet.  Watch the  Alternator Efficiency = Fuel Economy to learn more.
