ABSTRACT:
An engine (10) has a journal (18), a connecting rod (14) and a bearing (16) positioned between the journal (18) and rod (14). A lubrication system (36) for the engine (10) has a first passage (38) in the journal (18) and second and third passages (40,42) disposed between the journal (18) and bearing (16). The first passage (38) is positionable in fluid communication with the second and third passages (40,42) in response to rotation of the journal (18) for supplying lubricant therethrough to the bearing (16), journal (18) and piston areas. The first passage (38) is in continuous fluid communication with at least one of the second and third passages (40,42) to supply an uninterrupted flow of lubricant for maximum lubrication and cooling of the bearing (16), journal (18) and piston areas of the engine (10). The second and third passages (40,42) are positioned at preselected angles (A.sub.4, A.sub. 7 ; A.sub.5, A.sub.6) from principal loading areas (26,28) of the bearing (16) to maximize bearing area for carrying the loads exerted through the connecting rod (14).
