Fuel Efficiency
Limiters are used as a means of increasing the fuel efficiency of commercial motor vehicles. Limiters can be individually adjusted by fleet owners to meet the performance requirements of many different driving conditions. A limiter used for this purpose, however, especially if it is mechanical in nature, is more commonly categorized as a governor. Electronic adjustments require special diagnostic equipment to access control settings, and are limited to authorized personnel, such as a fleet manager or mechanic.
Due to their electrical nature, however, it is still possible to drive an engine beyond the maximum RPM level set by the limiter. This most commonly occurs in the case of selecting the incorrect gear with a manual transmission - for example, selecting second gear instead of fourth after shifting out of third. The speed of the vehicle and the drive wheels may drive the engine far beyond its intended range in this situation, likely resulting in rapid engine wear, and in extreme cases possible outright engine failure.

Famous quotes containing the words fuel and/or efficiency:
“Beware the/easy griefs, that fool and fuel nothing./It is too easy to cry “AFRIKA!”/and shock thy street,/and purse thy mouth,/and go home to thy “Gunsmoke,” to/thy “Gilligan’s Island” and the NFL.”
—Gwendolyn Brooks (b. 1917)
“Nothing comes to pass in nature, which can be set down to a flaw therein; for nature is always the same and everywhere one and the same in her efficiency and power of action; that is, nature’s laws and ordinances whereby all things come to pass and change from one form to another, are everywhere and always; so that there should be one and the same method of understanding the nature of all things whatsoever, namely, through nature’s universal laws and rules.”
—Baruch (Benedict)
