Diameter of Port given Maximum Lift of Valve Solution

STEP 0: Pre-Calculation Summary

Formula Used

Diameter of Port = 4*Lift of Valve*cos(Valve Seat Angle)
d_p = 4*h_max*cos(α)
This formula uses 1 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)

Variables Used

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.
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.

STEP 1: Convert Input(s) to Base Unit

Lift of Valve: 11 Millimeter --> 0.011 Meter (Check conversion here)
Valve Seat Angle: 24.61 Degree --> 0.429525528915724 Radian (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

d_p = 4*h_max*cos(α) --> 4*0.011*cos(0.429525528915724)

Evaluating ... ...

d_p = 0.040003191381764

STEP 3: Convert Result to Output's Unit

0.040003191381764 Meter -->40.003191381764 Millimeter (Check conversion here)

FINAL ANSWER

40.003191381764 ≈ 40.00319 Millimeter <-- Diameter of Port

(Calculation completed in 00.004 seconds)

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)

Maximum Lift of Valve for Flat Headed Valves

Go Lift of Valve = Diameter of Port/4

Diameter of Port given Maximum Lift of Valve Formula

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