INTERNAL COMBUSTION ENGINE WITH LUBRICATION BY CIRCULATION OF OIL UNDER PRESSURE ACCORDING TO THE DRY SUMP PRINCIPLE

摘要

Internal combustion engine with lubrication by circulation of oil under pressure according to the dry sump principle, in particular for an opposed cylinder engine with a crankcase with an oil suction chamber (dry sump) formed in its bottom part from which lubricant oil is conveyed via an oil recirculating pump provided with an oil suction line to an oil reservoir (wet sump), while the lubricant oil in the oil reservoir is supplied to the consumers via a main feed pump. It is proposed that an annular chamber (32, 34) arranged about the cylinder be provided as part of the oil recirculation circuit to the oil reservoir (16, 18).
