Bearing Pressure on Piston Pin Bush

Go Bearing Pressure of Piston Pin Bush = Force on Piston Pin Bearing/(Inner Diameter of Bush on Piston Pin*Length of Bush on Piston Pin)

Maximum Force Acting on Piston Pin Bearing given Allowable Bearing Pressure

Go Force on Piston Pin Bearing = Inner Diameter of Bush on Piston Pin*Length of Bush on Piston Pin*Bearing Pressure of Piston Pin Bush

Bearing Pressure on Crank Pin Bush

Go Bearing Pressure of CrankPin Bush = Force on Crank Pin Bearing/(Inner Diameter of Bush on Crank Pin*Length of Bush on Crank Pin)

Maximum Force Acting on Crank Pin Bearing given Allowable Bearing Pressure

Go Force on Crank Pin Bearing = Inner Diameter of Bush on Crank Pin*Length of Bush on Crank Pin*Bearing Pressure of CrankPin Bush

Maximum Force Acting on Piston Pin Bearing

Go Force on Piston Pin Bearing = pi*Inner Diameter of Engine Cylinder^2*Maximum Pressure in Engine Cylinder/4

Mass of Reciprocating Parts in Engine Cylinder

Go Mass of Reciprocating Parts in Engine Cylinder = Mass of Piston Assembly+Mass of Connecting Rod/3

Minimum Height of Connecting Rod at Small End

Go Height of Connecting Rod Section at End = 0.75*Height of Connecting Rod at Mid Section Small End

Maximum Height of Connecting Rod at Small End

Go Height of Connecting Rod Section at Small End = 0.9*Height of Connecting Rod at Mid Section

Minimum Height of Connecting Rod at Big End

Go Height of Connecting Rod Section at Big End = 1.1*Height of Connecting Rod at Mid Section

Angular Velocity of Crank given Engine Speed in RPM

Go Angular Velocity of Crank = 2*pi*Engine Speed in Rpm/60

Maximum Height of Connecting Rod at Big End

Go Height of Connecting Rod Section = 1.25*Height of Connecting Rod at Mid Section

Crank Radius given Stroke Length of Piston

Go Crank Radius of Engine = Stroke Length/2

Minimum Height of Connecting Rod at Big End Formula

Height of Connecting Rod Section at Big End = 1.1*Height of Connecting Rod at Mid Section
H_big = 1.1*H_m

What is connecting rod?

The connecting rod is a connection between the piston and a crankshaft. It joins the piston pin with the crankpin. The small end of the connecting rod is connected to the piston pin and the big end to the crank pin. The purpose of the connecting rod is to convert the linear motion of the piston into the rotary motion of the crankshaft.

Shape of Connecting Rod

The connecting rod consists of an I-beam cross-section and is made of forged steel. Aluminum alloy is also used for connecting rods. They are precisely matched in sets of similar weight in order to maintain engine balance. The lighter the connecting rod and piston, the greater the resulting in power and the lesser the vibration because the reciprocating weight is less. The connecting rod carries the power thrust from the piston to the crankpin and hence it must be very strong, rigid and also as light as possible.
