Abstract
A thrust washer for an internal combustion engine may include a metal base having a contact surface and a slip surface. The contact surface may be in operative communication with an engine block. The slip surface may define at least one ramp section, at least one flat horizontal section, and at least one oil channel. The ramp section and the flat horizontal section may be connected via an asymptotic curved surface. The ramp section may be positioned asymptotically towards the flat horizontal section.
