Rocker Locks

 In internal combustion engines a rocker arm is a valve train component. As rocker arm is acted on with the help of a camshaft lobe, it pushes and opens either the intake or exhaust valve. This during the intake stroke or exhaust gases to be expelled during the exhaust stroke allows fuel and air to be drawn into the combustion chamber. In the 19th-century rocker arms were first invented and since then they have been changed a little in function. However, in both efficiencies of operation and construction materials there have been improvements made. By using composite materials we analyze rocker arms. In optimizing Rocker Arm, strength, stability, durability, high dimension, wear resistance, toughness, material cost and economic play major role. Conveying radial movement into linear movement at the poppet valve from the cam lobe, a rocker arm is an oscillating lever that so that it can be opened. Lash adjusters are also used for this purpose. While the other end acts on the valve stem
