Formulary Piston Force

Pressure produces piston force

An average working pressure, determined through all the strokes is built up. This pushes the piston with a certain amount of force in the direction of the crankshaft. The strength of this force also depends on of the piston surface-area. The highest average pressures of about 16 bar are found in F3 engines.

The piston surface is calculated from the flat, circular area,
notfrom a possibly very uneven area.

F = A · pm

A =

pm =

1 bar = 10 N/cm
1 Pascal = 1 N/m
1 bar = 100.000 Pascal


Var. set:

pm = 8,8 bar; A = 728 mm = 7,28 cm

F in N


F = 10 · A · pm = 10 · 7,28 cm · 8,8 bar = 640,64 N               Top of page               Index
