STEP 0: Pre-Calculation Summary

Formula Used

Connecting Rod Length to Crank Radius Ratio = Connecting Rod Length/Crank Radius of Engine
R = r/r_c
This formula uses 3 Variables

Variables Used

Connecting Rod Length to Crank Radius Ratio - Connecting Rod Length to Crank Radius Ratio is defined as the ratio of connecting rod length to the crankshaft radius of an IC engine.
Connecting Rod Length - (Measured in Meter) - Connecting Rod Length is defined as the total length of the connecting rod of an IC engine.
Crank Radius of Engine - (Measured in Meter) - Crank Radius of Engine is the length of the crank of an engine. It is the distance between crank center and crank pin, i.e. half stroke.

STEP 1: Convert Input(s) to Base Unit

Connecting Rod Length: 150.1 Millimeter --> 0.1501 Meter (Check conversion here)
Crank Radius of Engine: 137.5 Millimeter --> 0.1375 Meter (Check conversion here)

Why is the ratio of cylinder bore to piston stroke significant?

The ratio of cylinder bore to piston stroke is most of the time defined as the Greek letter zeta ζ. For passenger road vehicles the bore to stroke ratio is usually from 0.8 to 1.2. When the bore is equal to the stroke, B = S, the engine is called square engine. If the stroke is higher than the bore the engine is under square. If the length of the stroke is less than the bore diameter the engine is called over square.
