IMPORTANT TECHNICAL TERMS OF AUTOMOTIVE VEHICLES


1.)AERODYNAMIC DRAG– is the air resistance to the motion of the vehicle.This consists of profile drag, induced drag, skin friction drag, interference drag, and cooling and ventilation drag.

2.)AERODYNAMIC LIFT– is the vertical component of the resultant force caused by the pressure distribution on the vehicle body.

3.)AIR BRAKE – A braking system which uses compressed air to supply the effort required to apply brakes.

4.)BOOSTER – Device incorporated in a car system (such as brake and steering),to increase pressure output or decrease amount of effort required to operate or both.

5.)CAMBER ANGLE – The outward (positive) or inward (negative) angle of the wheel centre line to absolute vertical.

6.)CASTER ANGLE – The rearward (positive) or forward (negative) angle of the steering axis to absolute vertical.

7.)CLUTCH PEDAL – A pedal in the drivers compartment that operates the clutch.

8.)CLUTCH SLIPPAGE – A condition in which the engine over revs during shifting or acceleration.

9.)DUAL BRAKE SYSTEM – Tandem or dual master cylinder to provide a brake system that has two separate hydraulic systems, one operating the front brakes, the other operating the rear brakes.

10.)EPICYCLIC GEAR– In the epicyclic gearing, at least one gear not only rotates about its own axis, but also rotates about some other axis.
