AN ENGINE ASSEMBLY

The present disclosure is directed towards an engine assembly (10) comprising a crankcase (22), a crankshaft (30), a lubrication system (40) and fluid guide arrangement (50). During rotation the crankshaft (30) is configured to drive a crankcase fluid flow (48) in a crankcase chamber (23). The lubrication system (40) comprises a lubricant drain (42) for a drain fluid flow (38) therethrough extending to a drain aperture (46) at the crankcase chamber (23). The fluid guide arrangement (50) is located adjacent or in proximity to the drain aperture (46). The fluid guide arrangement (50) is configured for guiding crankcase fluid flow (48) away from the drain aperture (46) and/or for reducing the pressure of the crankcase fluid flow (48) past the drain aperture (46), such that drain fluid flows (38) from the lubricant drain (42).
