Diameter of Valve Head given Diameter of Port and Projected Width of Valve Seat Solution

STEP 0: Pre-Calculation Summary

Formula Used

Diameter of Valve Head = Diameter of Port+2*Projected Width of Valve Seat
d_v = d_p+2*w
This formula uses 3 Variables

Variables Used

Diameter of Valve Head - (Measured in Meter) - Diameter of Valve Head is the diameter of the top part of valve of an IC engine, valve intakes and exhausts gases to and from an engine.
Diameter of Port - (Measured in Meter) - Diameter of Port is the diameter of the opening of the port of an IC Engine.
Projected Width of Valve Seat - (Measured in Meter) - Projected Width of Valve Seat is the projected width of the seat of the valve for a seat angle of 45 degrees and is perpendicular to valve length.

STEP 1: Convert Input(s) to Base Unit

Diameter of Port: 40 Millimeter --> 0.04 Meter (Check conversion here)
Projected Width of Valve Seat: 3 Millimeter --> 0.003 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

d_v = d_p+2*w --> 0.04+2*0.003

Evaluating ... ...

d_v = 0.046

STEP 3: Convert Result to Output's Unit

0.046 Meter -->46 Millimeter (Check conversion here)

FINAL ANSWER

46 Millimeter <-- Diameter of Valve Head

(Calculation completed in 00.004 seconds)

What is a valve gear mechanism?

The valve gear mechanism is a subassembly of the IC engine and its function is to open and close the inlet and exhaust valves at a proper time with respect to the position of the piston and crankshaft. The fuel is admitted into the cylinder when the inlet valve is open. Also, the burnt gases escape when the exhaust valve is open. The main parts of a valve-gear mechanism are valve, spring, tappet, rocker arm, pushrod, cam, and camshaft.
