Abstract

An engine lubrication apparatus has an oil sump provided at a lower side of an engine, a scavenge pump for sending oil in the oil sump to an oil tank, and a feed pump for supplying the oil in the oil tank to the engine. The engine lubrication apparatus has: a crankcase with side portions extending in parallel with the axis of a crankshaft on both sides and each constituted of inner and outer sidewalls arranged to create a space open at the lower side between the sidewalls; a first oil-pan member attached to lower portions of the inner sidewalls of the crankcase and forming the oil sump; and a second oil-pan member attached to lower portions of the outer sidewalls and forming the oil tank together with the spaces, the second oil-pan member being spaced apart from the first-oil-pan member an covering the first oil-pan member from below.
