A device 10 for collecting oil from a marine engine 40 has a helical collection conduit 12 connected to receive a mixture of oil and scavenge gas, i.e. air, from the marine engine. The curvature of the helical conduit and the flow speed distribution in the tube combine to cause the oil to accumulate on the inner surface of the conduit, from where it drains under gravity into a collection container 30. The invention also includes a drain pipe 42 for extracting cylinder drain oil from the under-piston space of the marine diesel engine, the drain has a run-off pipe extending laterally from the under-piston space, the run-off pipe permitting free flow of scavenge air from the engine to an outlet. |
