Abstract
A lubricant filler structure for an internal combustion engine includes a lubricant filler tube having a lower end connected to the crankcase and an upper end forming a filling port. The filler tube is disposed forwardly at an angle with respect to the vertical. The engine also has a cover member through which the lubricant filler structure extends. The cover member and the lubricant filler structure are configured to enhance accessibility of a lubricant filling port by the user.
Claims18
An outboard motor comprising a drive unit, a bracket assembly adapted to be mounted on an associated watercraft to support the drive unit, a cowling assembly, the drive unit comprising an internal combustion engine, the engine comprising an engine body including a crankcase, a moveable member moveable relative to the engine body, the engine body and the moveable member together defining a combustion chamber, the engine further comprising an intake passage for introducing air into the combustion chamber, the intake passage extending from a rear portion of the combustion chamber, the intake passage further extending to an external side of the crankcase and to a forward side of the crankcase, the intake passage and the crankcase defining a space therebetween, and a lubricant filler structure, comprising a cap, and a lubricant filler tube having a lower end connected to the crankcase and an upper end forming a filling port, at least a portion of the lubricant filler structure being disposed within the space defined by the crankcase and the intake passage.
An internal combustion engine comprising a cowling assembly, an engine body including a flywheel assembly, a crankcase, a moveable member moveable relative to the engine body, the engine body and the moveable member together defining a combustion chamber, the engine further comprising an induction system, the engine body and the induction system defining a space therebetween, and a lubricant filler structure comprising a cap and a lubricant filler tube having a lower end connected to the crankcase and an upper end forming a filling port, at least a portion of the lubricant filler structure positioned within the space, wherein the filler tube is disposed forwardly at an angle with respect to the vertical.
An internal combustion engine for use with its crankshaft extending in a generally vertical direction, said internal combustion engine comprising an engine body, said engine body comprising a crankcase member, a cylinder block and a cylinder head, said crankcase member and said cylinder block being joined together to define a crankcase chamber, said crankshaft extending in a generally vertical direction through said crankcase chamber, at least one cylinder bore being formed in said cylinder block, a piston reciprocally mounted within said cylinder bore and being connected to said crankshaft, a flywheel being secured to said crankshaft and being disposed above an upper surface of said engine body, a cover member extending over said flywheel, an oil fill tube being connected to an upper portion of said crankcase member and said oil fill tube extending away from said cylinder head at an angle, wherein said cover member comprises a recess and said oil fill tube extends to said recess.
