Small air-cooled engine assembly with dry sump lubrication system

An engine assembly, comprising:

• an internal combustion engine comprising:
• an engine block;
• an oil gallery configured to distribute oil;
• a crankcase cover;
• and a crankcase chamber defined by the engine block and the crankcase cover;
• an external oil reservoir comprising:
• an oil tank defining an oil chamber;
• and an oil filter assembly comprising:
• a housing at least partially defining a filter chamber, wherein the filter chamber is in fluid communication with the oil chamber;
• a filter positioned within the filter chamber, the filter comprising filter media, a fill inlet, and an oil fill conduit in fluid communication with the fill inlet and extending through the filter media so that oil can be added to the oil chamber through the fill inlet and the oil fill conduit without being filtered by the filter media, wherein the filter further comprises a handle that extends through a midpoint of the fill inlet and includes a grasping portion located above the fill inlet to provide a grasping point for a user to manipulate the filter;
• and a bypass valve positioned in a bypass passage configured to selectively open in response to a threshold pressure to allow oil to flow from the filter chamber to the oil chamber without being filtered by the filter media;
• a supply pump in fluid communication with the oil chamber and the oil gallery, wherein the supply pump is configured to draw oil from the oil chamber and provide pressurized oil to the oil gallery;
• and a return pump in fluid communication with the crankcase chamber and the filter chamber, wherein the return pump is configured to draw oil from the crankcase chamber and provide pressurized oil to the filter chamber;
• wherein the filter is configured to filter the pressurized oil provided to the filter chamber;
• wherein the crankcase chamber and the oil chamber have an overall oil capacity that provides at least five hundred hours of engine oil life.
