Automotive Technical terms and abbreviations overview used in the industry, Guide and explanations.
The following are examples of Mid Modern technical terms recommended for general use worldwide.For in-depth specific terms also see terms for historic vintage and specific areas such as Paint.
GAWR:
(Gross axle weight rating) the total maximum weight an axle is désigned to carry.
GCW:
(Gross combined weight) total combined weight of a tow vehicle and trailer.
GARAGE SHIFT
initial engagement feel of transmission, neutral to reverse or neutral to a forward drive.
GARAGE SHIFT FEEL:
A quick check of the engagement quality and responsiveness of reverse and forward gears. This test is done with the vehicle stationary.
GEAR:
A toothed mechanical device that acts as a rotating lever to transmit power or turning effort from one shaft to another. (See gear ratio.)
GEAR RATIO:
A ratio expressing the number of turns a smaller gear will make to turn a larger gear through one revolution. The ratio is found by dividing the number of teeth on the smaller gear into the number of teeth on the larger gear.
GEARBOX:
Transmission
GEAR REDUCTION:
Torque is multiplied and speed decreased by the factor of the gear ratio. For example, a gear ratio changes an input torque of 180 ft. lbs. and an input speed of 2700 rpm to 540 Ft. lbs. and 900 rpm, respectively. (No account is taken of frictional losses, which are always present.)
GEARTRAIN:
A succession of intermeshing gears that form an assembly and provide for one or more torque changes as the power input is transmitted to the power output.
GEL COAT:
A thin coat of plastic resin covering fiberglass body panels.
GENERATOR:
A device which produces direct current (DC) necessary to charge the battery.
GOVERNOR:
A device that senses vehicle speed and generates a hydraulic oil pressure, As vehicle speed increases, governor oil pressure rises.
GROUND CIRCUIT:
(See circuit, ground.)
GROUND SIDE SWITCHING:
The electrical/electronic circuit control switch is located after the circuit load.
GVWR: (Gross vehicle weight rating)
total maximum weight a vehicle is designed to carry including the weight of the vehicle, passengers, equipment, gas, oil, etc.
