t_h = D_i*sqrt(0.162*p_max/σ_c)
This formula uses 1 Functions, 4 Variables

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

Thickness of Cylinder Head - (Measured in Meter) - Thickness of cylinder head is the thickness of engine cylinder cover or head along the length of cylinder.
Inner Diameter of Engine Cylinder - (Measured in Meter) - Inner Diameter of Engine Cylinder is the diameter of the interior or the inside surface of an engine cylinder.
Maximum Gas Pressure inside Cylinder - (Measured in Pascal) - Maximum gas pressure inside cylinder is the maximum amount of pressure that can be generated inside the cylinder.
Circumferential Stress in Engine Wall - (Measured in Pascal) - Circumferential Stress in Engine Wall acts perpendicular to the axial direction, generated to resist the bursting effect that results from the application of pressure.

STEP 1: Convert Input(s) to Base Unit

Inner Diameter of Engine Cylinder: 128.5 Millimeter --> 0.1285 Meter (Check conversion here)
Maximum Gas Pressure inside Cylinder: 4 Megapascal --> 4000000 Pascal (Check conversion here)
Circumferential Stress in Engine Wall: 32 Newton per Square Millimeter --> 32000000 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t_h = D_i*sqrt(0.162*p_max/σ_c) --> 0.1285*sqrt(0.162*4000000/32000000)

Evaluating ... ...

t_h = 0.0182858705699237

STEP 3: Convert Result to Output's Unit

0.0182858705699237 Meter -->18.2858705699237 Millimeter (Check conversion here)

FINAL ANSWER

18.2858705699237 ≈ 18.28587 Millimeter <-- Thickness of Cylinder Head

Cylinder Head

In an internal combustion engine, the cylinder head (often informally abbreviated to just head) sits above the cylinders on top of the cylinder block. It closes at the top of the cylinder, forming the combustion chamber. This joint is sealed by a head gasket. In most engines, the head also provides space for the passages that feed air and fuel to the cylinder, and that allow the exhaust to escape. The head can also be a place to mount the valves, spark plugs, and fuel injectors.
