Product Description

Piston pin offset
The piston movement inside the cylinder has 3 degrees of freedom, 1 primary and 2 secondary:
along the vertical axis of the cylinder, between the top dead centre (TDC) and bottom dead centre (BDC) (primary, y-axis)
around the pin axis (secondary, α – angle)
along the skirt axis (secondary, x – axis)
The primary movement is generating torque at the crankshaft, this is desired from the mechanical point of view. The secondary movements happen due to the combination of several factors: connecting rod bidirectional movement and clearance between piston and cylinder. Both secondary movements cause friction with the cylinder walls and also noise, vibration (piston slap).
