Abstract
An engine structure is provided that basically includes a cylinder block, an oil circulation pathway and a lubricating oil reservoir. The cylinder block has an upper end for receiving a cylinder head, a lower end for receiving an oil pan, and a crankshaft receiving portion. The oil circulation pathway is arranged to convey lubricating oil by gravity to at least an area located above the crankshaft receiving portion of the cylinder block for supplying lubricating oil to a crankshaft. The lubricating oil reservoir is arranged to store lubricating oil. The lubricating oil reservoir has an open top end for receiving downwardly flowing lubricating oil. The open top end of the lubricating oil reservoir is arranged relative to the oil circulation pathway such that lubricating oil spilling out of the open top end of the lubricating oil reservoir falls into the oil circulation pathway.
