Adjusting Sleeve

An internally threaded sleeve located between the tie rod ends. The sleeve is rotated to set toe in/toe out.

Adjustment

To make a necessary or desired change in clearance, fit or setting.

ADLO

Automatic disengagement and lock out.

Admittance (y)

The ease with which current flows in an ac circuit. It is the reciprocal of impedance and is measured in mhos.

ADS

Anti-diesel solenoid or a Euporean Acronym for an Automatic Damping System.

Adsorb

To collect a very thin layer on the surface of material.

Adsorbent Media

Generally used in filters for the removal of odors, smoke, fumes, and some impurities. The chief adsorptive granular media used for filters are activated charcoal and similar forms of carbon, Fuller's earth, and other active clays. Also see canister filter and filter.

Adsorption

The attraction and/or retention of particles by molecular attraction or electrostatic forces present between the particles and a filter medium.

ADSR

Auto shut down relay.

Advance Curve

A term generally relating to spark advance curve.

AEA

An acronym for the Automotive Electrical Association.

AEGS

Automatic Electronic Gearbox Control.

Aera

An acronym for Automotive Engine Rebuilders Association.

Aerobic Sealer

A silicone rubber sealing compound that requires oxygen for curing, such as RTV, used to hold parts together.

Aerodynamic

The ease with which air can flow over the vehicle during higher speed operation. An aerodynamically sound vehicle has very little wind resistance.

Aerodynamic Drag

The resistance of air against an object, such as an automobile, trying to pass through it. Also referred to as air drag and air resistance.

Aerodynamic Force

A force created aerodynamically, such as by an air foil.

Aerodynamic Resistance

Resistance of the air against an object, such as a vehicle, trying to pass through it. The result of four factors; coefficient of drag, frontal area, vehicle speed, and air density. Also referred to as air drag, air resistance, and aerodynamic drag.
