Description
- The present disclosure relates to an engine, and particularly to guiding a lubricating fluid from a cylinder of the engine.
- A typical engine system includes an engine body having one or more casted components, such as a cylinder block, a cylinder head etc. One or more fluid passages are formed in the engine body for receiving and transporting lubricating oil and/or a coolant to relevant portions of the engine. The lubricating oil may be supplied to different bearing components and other moving components, such as a crankshaft, a connecting rod and the like. In some cases, a surface of the piston or piston rings may deflect the oil from the cylinder to counterweights of the crankshaft that are located below the cylinder. However, due to contact of the oil falling from the cylinder onto the counterweights and/or presence of oil mist in the crank case provides resistance to a movement of counterweights and thereby the crankshaft in the mist, which may decrease the efficiency of the engine.

guide member 134 using methods such as, but not limited to, fasteners, adhesives and the like. Alternatively, the first portion 142 and the second portion 144 may be integral to each other to form a unitary construction. For example, the first portion 142 may be theguide member 134 having a curvilinear shape, while the second portion 144 may be an extension member coupled to the first portion 142. The second portion 144 may also be curvilinear so as to form a rail or drain pipe configuration. In another example, at least one of the first portion 142 and the second portion 144 may have a planar shape. - Referring to
FIG. 9 , theguide member 134, according to yet another embodiment is illustrated. As shown, theguide member 134 is disposed below thecylinder member 108. Further, theguide member 134 may be indirectly coupled to thecylinder member 108 by coupling to the crankcase 122. As shown, theguide member 134 has a curvilinear shape. Further, the axis of curvature (not shown) of theguide member 134 is substantially perpendicular to the axis MM' of thecylinder member 108. With such a configuration, spilling of the lubricant from sides of thecylinder member 108 onto thecounterweights 128 may be avoided. - An outer surface (not shown) of the
guide member 134, according to various embodiments may be configured to at least partly direct the lubricating fluid away from anadjacent counterweight 128 of thecrankshaft 124 of theengine 100. In an embodiment, at least a portion of theguide member 134 may be parallel to the adjacent counterweight 128 (best shown inFIG. 1 ). Accordingly, at least a portion of theguide member 134 that is extending from thecylinder member 108 may act as a ramp over theadjacent counterweight 128 to direct the lubricating fluid away from theadjacent counterweight 128. Further, the outer surface of theguide member 134 may also be configured to direct the lubricating fluid from thecylinder member 108 into theoil pan 130 of theengine 100. - In various other embodiments, the
guide member 134 may embody any other shapes based on other parameters, such as tolerances between different components of theengine 100 and the like. For example, theguide member 134 may be designed to conform to the dimensions and shape of thecorresponding counterweights 128. Moreover, additionally, a shape of the correspondingcounterweights 128 and/or other components may be modified so as to accommodate theguide member 134. - In an embodiment,
multiple guide members 134 may be coupled to thecylinder member 108. Further, theguide members 134 may be disposed so as to allow general movement of other components of theengine 100. - In one embodiment, the
guide member 134 is made of one of a sheet metal. In another embodiment, theguide member 134 is made of plastic. In various other embodiments, theguide member 134 may be made of any other light weight materials including, but not limited to, polymers, composites and the like. For example, theguide member 134 may be implemented as a coating on thecylinder member 108. - The present disclosure relates to the
guide member 134 for guiding the lubricating fluid. Theguide member 134 is coupled to the thecylinder member 108 and is disposed outside thecylinder member 108. Further, theguide member 134 may be configured to direct a flow of the lubricating fluid from thecorresponding cylinder member 108 away from theadjacent counterweight 128. With such an implementation in all thecylinder members 108 of theengine 100, thecounterweights 128 of thecrankshaft 124 may be shielded from contacting with the lubricating fluid falling from thecylinder member 108. - As such, various aerodynamic forces such as, lift force, drag force and the like due to a flow of the lubricating fluid or a mist of the fluid on the
counterweight 128 may be reduced. Further, a resistance to a movement of thecounterweight 128 and thereby a rotation of thecrankshaft 124 due to the lubricating fluid may be reduced. - Further, the
guide member 134 may be made of light weight materials such as, plastic, sheet metal, polymers and the like. Additionally, theguide member 134 may be implemented on the existing engines with little or no modification to other components of theengine 100. Moreover, dimensions and a shape of theguide member 134 may be customized to suit different applications. - While aspects of the present disclosure have been particularly shown and described with reference to the embodiments above, it will be understood by those skilled in the art that various additional embodiments may be contemplated by the modification of the disclosed machines, systems and methods within the scope of the claims.
Claims (7)
