Stroke Length of Piston given Mean Velocity of Piston and Engine Speed Solution

STEP 0: Pre-Calculation Summary

Formula Used

Stroke Length = (60*Mean Piston Speed)/(2*Engine Speed in rpm)
l_s = (60*s_p)/(2*N)
This formula uses 3 Variables

Variables Used

Stroke Length - (Measured in Meter) - Stroke length is the distance traveled by piston in cylinder from BDC to TDC or vice versa.
Mean Piston Speed - (Measured in Meter per Second) - Mean Piston Speed is the average speed of the piston over one engine revolution.
Engine Speed in rpm - Engine Speed in rpm is the speed at which the crankshaft of the engine rotates.

STEP 1: Convert Input(s) to Base Unit

Mean Piston Speed: 4.5 Meter per Second --> 4.5 Meter per Second No Conversion Required
Engine Speed in rpm: 500 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

l_s = (60*s_p)/(2*N) --> (60*4.5)/(2*500)

Evaluating ... ...

l_s = 0.27

STEP 3: Convert Result to Output's Unit

0.27 Meter -->270 Millimeter (Check conversion here)

FINAL ANSWER

270 Millimeter <-- Stroke Length

What are Engine Valves?

Engine valves are mechanical components used in internal combustion engines to allow or restrict the flow of fluid or gas to and from the combustion chambers or cylinders during engine operation. Functionally, they perform similarly to many other types of valves in that they block or pass flow, however, they are a purely mechanical device that interfaces with other engine components such as rocker arms in order to open and close in the correct sequence and with the correct timing.
