Abstract
In a working 4-cycle engine including a crankcase, a cylinder block inclined with respect to the crankcase, and an oil pan located in a lower portion of the crankcase. An auxiliary oil tank is disposed below the cylinder block in the direction of inclination of the cylinder block. The auxiliary oil tank communicates with the inside of the oil pan and normally assumes a position higher than the level of oil stored in the oil pan. However, when the engine is tilted down in the direction of inclination of the cylinder block, the oil stored in the oil pan flows into and is accumulated in the auxiliary oil tank. Thus, even if the engine is tilted down in the direction of inclination of the cylinder block, the oil stored in the oil pan is prevented from flowing into the cylinder.
