Automotive shock absorber functions by forcing oil through small internal passages in a tubular housing.(http://www.wzholid.cn) It is an important device that functions by converting the motion (kinetic energy) into heat. The device ensures vehicle control, comfortable ride, and prolongs the life of other components. Automotive shock absorber falls in two important categories:

Gas Charged Automotive Shock Absorber: The gas charged automotive shock absorber uses nitrogen gas that prevents bubble formation in the oil and enhances the capacity of the shock absorber.

Conventional Automotive Shock Absorber: In conventional automotive shock absorber piston's movement inside a cylinder is damped by the passing of oil through one or more orifices.

The auto shock absorber manages the suspension movement and the action of the spring. It plays major role in maintaining the stability of the chassis and body even in the irregular road conditions
