An oil collection system includes a boat that has an engine. A pan is removably coupled to the engine such that the pan may capture oil leaked from the engine. A plurality of clips is provided and each of the clips is coupled to the pan. Each of the clips engages the bottom end of the engine such that the pan is removably retained on the engine. A filter is positioned within the pan such that the filter filters the oil. A gauge is coupled to the pan such that the gauge may display an amount of oil contained within the pan. A drain is coupled to the pan such that the drain may selectively drain the oil from the pan.

A polygon in a tabular portion includes first and second axes of symmetry substantially orthogonal to each other. A top surface of the tabular portion has a swelling portion with an outline that is line-symmetric with respect to the first and second axes of symmetry. In a lateral half portion of the outline, a short-side side crest portion that is convex toward the polygonal outline in the direction of the first axis of symmetry, concave corner-side trough portions connected to each end of the short-side side crest portion and long-side side crest portions that are connected to each corner-side trough portion and convex toward the polygonal outline are formed. On one of a top surface and an undersurface of the swelling portion, a pair of lateral ribs or a pair of longitudinal ribs that spreads toward the polygonal outline and transversely crosses the swelling portion is formed.

A vibration and noise abatement reduction method and apparatus for a fluid reservoir containing an automotive fluid and having a bottom wall. At least a portion of the fluid reservoir is formed of or carries a shape memory change material undergoing shape change at a threshold temperature. A controller detects a match between the vehicle vibration frequency at a measured vehicle operating characteristic and the resonant frequency of the fluid reservoir and varies the resonant vibration frequency of the fluid reservoir by changing the stiffness of at least a portion of the reservoir through the supply of heat to the fluid reservoir resulting in a change in the shape of at least the shape memory change material in the fluid reservoir. The heat is supplied from an electrical conductor in heat transfer relation with the fluid reservoir or an elevated temperature of the automotive fluid in the fluid reservoir.

A work vehicle includes an engine, an intake passage through which combustion air flows from an ambient air inlet to an engine, an air cleaner for removing dust contained in the combustion air, a throttle valve for adjusting an intake amount of the combustion air by the engine, a blowby gas returning passage for returning blowby gas discharged from the engine to a mid portion of the intake passage, and an inclined passage portion that assumes a progressively downwardly inclined posture to be located at a lower position on downstream side in a flow direction, the inclined passage portion having a water draining portion at its lowermost end.

A noise reducing oil pan assembly for a motor vehicle engine, adapted for attachment to the engine block underside, includes outer and inner nested pan units supported in spaced relation defining an oil chamber between the units. An inflow gap between the upper opposed edge portions of the units upstanding walls is positioned subjacent the outflow of engine block return oil passages. With the engine running, the return oil flow fills the chamber and thereafter the overflow is received by the inner unit reservoir for re-circulation to the engine. The chamber oil provides a barrier that dampens engine noise radiating from the oil pan assembly.
摘要:
A method for making a sound-dampened automotive enclosure, such as an oil pan, having a metal constraining layer, a metal housing layer, and a viscoelastic layer sandwiched therebetween. In a preferred embodiment, the constraining layer and viscoelastic layer are between the housing layer and the die while the housing layer is being drawn. This results in a very close and snug fit between the layers, leading to enhanced sound-dampening effectiveness. The article thus produced is also disclosed.

A method of forming a structural oil pan via lost core molding is disclosed. The structural oil pan comprises a bracket portion configured for mounting to the vehicle, a pan portion integrated with the bracket portion and defining an oil reservoir, and a structural section formed via lost core molding and defining a cavity. The method comprises the step of lost core molding by forming a metal core, molding the bracket portion and/or the pan portion about the metal core, and removing the metal core to form the structural section in at least one of the bracket portion and the pan portion. The method also includes co-molding the bracket portion and the pan portion together to form the structural oil pan.
