Exhaust Lap Solution

STEP 0: Pre-Calculation Summary

Formula Used

Exhaust Lap = -Eccentricity or Throw of Eccentric*(sin(Crank Angle+Angle of Advance of the Eccentric))
e = -r*(sin(θ+α))
This formula uses 1 Functions, 4 Variables

Functions Used

sin - Sine is a trigonometric function that describes the ratio of the length of the opposite side of a right triangle to the length of the hypotenuse., sin(Angle)

Variables Used

Exhaust Lap - (Measured in Meter) - Exhaust Lap is the displacement of the valve from its mid-position at release and compression.
Eccentricity or Throw of Eccentric - (Measured in Meter) - Eccentricity or Throw of Eccentric is the extent to which the mantle veers from its axis, so it defines the rate at which the material falls through the chamber.
Crank Angle - (Measured in Radian) - Crank Angle refers to the position of an engine's crankshaft in relation to the piston as it travels inside of the cylinder wall.
Angle of Advance of the Eccentric - (Measured in Radian) - Angle of advance of the eccentric the angle in excess of 90° that a steam-engine valve gear is in advance of the crank.

STEP 1: Convert Input(s) to Base Unit

Eccentricity or Throw of Eccentric: 2.7 Millimeter --> 0.0027 Meter (Check conversion here)
Crank Angle: 15.5 Degree --> 0.27052603405907 Radian (Check conversion here)
Angle of Advance of the Eccentric: 32.3 Degree --> 0.563741348394062 Radian (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

e = -r*(sin(θ+α)) --> -0.0027*(sin(0.27052603405907+0.563741348394062))

Evaluating ... ...

e = -0.00200017240997394

STEP 3: Convert Result to Output's Unit

-0.00200017240997394 Meter -->-2.00017240997394 Millimeter (Check conversion here)

FINAL ANSWER

-2.00017240997394 ≈ -2.000172 Millimeter <-- Exhaust Lap

(Calculation completed in 00.004 seconds)
