Crankcase scavenged internal combustion engine |
摘要 |
An internal combustion engine including structure for lubricating at least one bearing disposed therein. The engine includes an engine housing including a cylinder with a reciprocating piston of the engine and a crankcase volume with a crankshaft having the at least one bearing operatively connected thereto, wherein the crankcase volume contains at least air and a lubricant. Additionally, the engine includes a counterweight arrangement that provides an essentially solid circular profile, at least one passageway on the counterweight arrangement extending to a location adjacent to the engine housing, and at least one passageway extending through the engine housing from a location adjacent to the counterweight to the at least one bearing, wherein the two passageways are selectably aligned by movement of the piston to cause a lubricating flow between the at least one bearing and the crankcase volume.
