Valve Seat Angle given Maximum Lift of Valve Solution

STEP 0: Pre-Calculation Summary

Formula Used

Valve Seat Angle = arccos(Diameter of Port/(4*Lift of Valve))
α = arccos(d_p/(4*h_max))
This formula uses 2 Functions, 3 Variables

Functions Used

cos - Cosine of an angle is the ratio of the side adjacent to the angle to the hypotenuse of the triangle., cos(Angle)
arccos - Arccosine function, is the inverse function of the cosine function.It is the function that takes a ratio as an input and returns the angle whose cosine is equal to that ratio., arccos(Number)

Variables Used

Valve Seat Angle - (Measured in Radian) - Valve Seat Angle is the angle of the seat of a valve from the direction perpendicular to the valve length.
Diameter of Port - (Measured in Meter) - Diameter of Port is the diameter of the opening of the port of an IC Engine.
Lift of Valve - (Measured in Meter) - Lift of Valve is the height to which the valve is lifted during operation for the flow of gases.

STEP 1: Convert Input(s) to Base Unit

Diameter of Port: 40 Millimeter --> 0.04 Meter (Check conversion here)
Lift of Valve: 11 Millimeter --> 0.011 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

α = arccos(d_p/(4*h_max)) --> arccos(0.04/(4*0.011))

Evaluating ... ...

α = 0.429699666151424

STEP 3: Convert Result to Output's Unit

0.429699666151424 Radian -->24.6199773286617 Degree (Check conversion here)

FINAL ANSWER

24.6199773286617 ≈ 24.61998 Degree <-- Valve Seat Angle

Valve Seat Angle given Maximum Lift of Valve

Go Valve Seat Angle = arccos(Diameter of Port/(4*Lift of Valve))

Maximum Lift of Valve given Diameter of Port and Valve Seat Angle

Go Lift of Valve = Diameter of Port/(4*cos(Valve Seat Angle))

Diameter of Port given Maximum Lift of Valve

Go Diameter of Port = 4*Lift of Valve*cos(Valve Seat Angle)

Force Required to Lift Engine Valve

Go Force to Lift Engine Valve = Stiffness of Valve Spring*Lift of Valve

Lift of Engine Valve

Go Lift of Valve = Force to Lift Engine Valve/Stiffness of Valve Spring

Maximum Lift of Valve for Flat Headed Valves

Go Lift of Valve = Diameter of Port/4

Valve Seat Angle given Maximum Lift of Valve Formula

Valve Seat Angle = arccos(Diameter of Port/(4*Lift of Valve))
α = arccos(d_p/(4*h_max))

Characteristics of material for engine valve
