Lubrication system for two-cycle engine

摘要

A lubrication system for two-cycle engine includes a lubricant recess formed in a wall of a crankcase. Oil that becomes deposited within the intake passageway is directed to the lubricant recess preferably by a guide groove and pools adjacently below a connecting rod endcap. As the crankshaft with attached connecting rod rotates, pooled oil is drawn into the interior of the connecting rod endcap. Preferably, oil holes are formed radially outward through the connecting rod endcap to throw collected oil around the crankcase chamber when exposed to a centrifugal force.
