Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Core Diameter of Tappet - (Measured in Meter) - Core Diameter of Tappet is defined as the smallest diameter of the thread of the tappet or the stud of a rocker arm.
Gas Load on Exhaust Valve - (Measured in Newton) - Gas Load on Exhaust Valve is the amount of force acting on the inner side of the exhaust valve due to the back pressure or cylinder pressure when the exhaust valve opens.
Inertia Force on Valve - (Measured in Newton) - Inertia Force on Valve is the force acting opposite to the direction of valve motion onto the valve.
Spring Force - (Measured in Newton) - Spring Force is the force exerted by a compressed or stretched spring upon any object that is attached to it.
Compressive Stress in Tappet - (Measured in Pascal) - Compressive Stress in Tappet or stud is the force per unit area that is responsible for the deformation of the tappet such that the volume of the material reduces and its length decreases.

STEP 1: Convert Input(s) to Base Unit

Gas Load on Exhaust Valve: 1680 Newton --> 1680 Newton No Conversion Required
Inertia Force on Valve: 115 Newton --> 115 Newton No Conversion Required
Spring Force: 8.88 Newton --> 8.88 Newton No Conversion Required
Compressive Stress in Tappet: 36.5 Newton per Square Millimeter --> 36500000 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

d_c = sqrt((4*(P_g+P+P_s))/(pi*σ_c)) --> sqrt((4*(1680+115+8.88))/(pi*36500000))

Evaluating ... ...

d_c = 0.00793254325324304

STEP 3: Convert Result to Output's Unit

0.00793254325324304 Meter -->7.93254325324304 Millimeter (Check conversion here)

FINAL ANSWER

7.93254325324304 ≈ 7.932543 Millimeter <-- Core Diameter of Tappet

What is an engine valve?

Engine valves are mechanical components used in internal combustion engines to allow or restrict the flow of fluid or gas to and from the combustion chambers or cylinders during engine operation. Functionally, they perform similarly to many other types of valves in that they block or pass flow, however, they are purely mechanical device that interfaces with other engine components such as rocker arms in order to open and close in the correct sequence and with the correct timing. The term engine valve may also refer to a type of check valve that is used for air injection as part of the emission control and exhaust gas recirculation systems in vehicles
