After being recently schooled on hydrodynamic lubrication (wipe that silly smirk off your face Shannow) I was wondering what happens to the wedge under different driving modes that effect it's ability to prevent wear.
I know engines show very little wear when they are operated at constant revs, munching miles on the motorway, and after understanding the above I can see why
A lot of engine wear takes place on the warm up phase of any engine so what is happening to the wedge when the oil is cold and thick to increase wear like this?
Also excessive wear takes place when the engine is labouring (probably only relevant to manual gearboxes) at low speed/high torque and in high torque situations in general so what's happening to the wedge here?
Is this why film strength and extreme pressure performance are so critical in protecting our engines from wear?
