  • Understanding Journal Bearings - EDGE

    The piston pin-bore bearing also acts as a form of journal bearing, so do the big-end bearings, covered in Chapters 19 and 20. Journal bearings usually operate in a hydrodynamic regime of lubrication as the generated pressures are low compared with those experienced by ball and rolling element bearings, gears and cam–follower pairs.

  • Understanding the Primary Difference Between Main and

    A ‘journal’ is the surface of a connecting rod or crankshaft which is in contact with the bearing. Since there needs to be an oil layer for lubrication between the inner surface of the bearing and the shaft, oil is supplied by an oil pump to the engine block. From here, it flows into the upper half of each main bearing.

Lag is also to blame for the lack of precision related to the control of there boost, and unlike superchargers, turbos are prone to sudden surges of power.
