<p>In a two cycle internal combustion engine (2), the sidefaces (60, 62) of the connecting rod (40) have grooves (64) formed therein dragging lubricant from the fuel-air-lubricant mixture in the crankcase (8) along the crankfaces (38, 40) of the crankarm discs (34, 36) of the crankshaft (24), providing a hydrodynamic bearing with a layer of lubricant separating the sidefaces of the connecting rod from the crankfaces of the crankarm discs such that the sidefaces of the connecting rod ride on a layer of lubricant, and eliminating the need to silver plate the sidefaces of the connecting rod.</p> |
