Core Diameter of Tappet or Stud of Rocker Arm of Engine Valve

LaTeX Go Core Diameter of Tappet = sqrt((4*(Gas Load on Exhaust Valve+Inertia Force on Valve+Spring Force))/(pi*Compressive Stress in Tappet))

Compressive Stress in Tappet of Rocker Arm of Engine Valve

LaTeX Go Compressive Stress in Tappet = (4*(Gas Load on Exhaust Valve+Inertia Force on Valve+Spring Force))/(pi*Core Diameter of Tappet^2)

Compressive Force on Tappet of Rocker Arm of Engine Valve given Stress in Tappet

LaTeX Go Compressive Force on Tappet = (Compressive Stress in Tappet*pi*Core Diameter of Tappet^2)/4

Compressive Force on Tappet of Rocker Arm of Engine Valve

LaTeX Go Compressive Force on Tappet = Gas Load on Exhaust Valve+Inertia Force on Valve+Spring Force

Engine Valve Motion

The motion of the engine valves is driven by the camshaft of the engine, which contains a series of lobes or cams that serve to create the linear motion of the valve from the rotation of the camshaft. The number of cam lobes on the camshaft is equal to the number of valves in the engine. Regardless of the engine design, the basic movement of the engine valves occurs by the cam riding against a lifter or a tappet that provides a force that presses against the valve stem and compresses the valve spring, thereby removing the spring tension that keeps the valve in the closed position. This movement of the valve stem lifts the valve off the seat in the cylinder head and opens the valve. Once the camshaft rotates further and the cam lobe moves so that the eccentric portion is no longer directly in contact with the lifter or tappet, the spring pressure closes the valve as the valve stem rides on the centric portion of the cam lobe.
