- Damper

Damper
- A Friction device sometimes called a Shock absorber. Used for controlling and damping spring Oscillations. The springs actually absorb road shocks; the dampers convert the energy imparted to the springs into thermal energy (by friction), which is dissipated to the atmosphere or the vehicle's Chassis. Dampers are distinguishable by the type of friction involved, mechanical or Hydraulic but most modern cars used tubular-shaped Hydraulic shock absorbers. Because they affect up and down wheel motions, dampers are an important link in tuning a vehicle's ride and handling.
- A movable plate which permits or restricts the flow of liquids or gasses.
Also see
- Damper piston
- A piston in a cylinder whose movement is restricted by a liquid or gas, which thus also restricts the movement of another member to which it is connected.
- Damper springs
- Springs in a clutch plate providing a cushion against sudden loads due to abrupt engagement
- Damper strut
- A suspension strut whose hub carrier is attached to the spring element rather than to the damper tube. Compare Macpherson strut
- Damping
-
- Cushioning of force.
- The action of suspension to control the speed of movement through its travel, usually by a piston running through oil and thus gives a smoother ride. It vastly improves that smoothness of ride offered.

- Damping restriction
- The bore of a small cross section in the fuel distributor of the K-Jetronic type system. It dampens sensor plate movement in the air flow sensor during high load and low rpm conditions

- Daytime running lights
- (DRLs) A safety-oriented lighting system in which the headlights or other front lights are constantly on even during the day. They help to prevent possible accidents because oncoming traffic can be seen. December 1, 1989, Canada became the second country after Norway to require daytime running lights on all new passenger vehicles. In other countries the implementation of DRLs has had mixed response.
