Abstract
An internal combustion engine includes an engine lubrication fluid storage system having a primary storage volume and a secondary storage volume separate from the primary storage volume. The secondary storage volume is connected to the primary storage volume by a fluid flow path, which is typically closed by a valve associated with the filtration device. Removing the filter device during a maintenance event unseals the fluid flow path, allowing fluid to flow from the secondary storage volume to the primary storage volume for discharge from the engine during the maintenance event.
Description
Cross Reference to Related Applications
The present application claims priority from british patent application number 1916704.8 filed on 11/15 2019, which is incorporated herein by reference.
Technical Field
The present invention relates to an internal combustion engine including a lubrication system, and more particularly to an exhaust system for an engine lubrication fluid storage system separate from a crankcase.
Background
In an internal combustion engine, a supply of lubricating fluid, such as engine oil, is provided in an oil pan at the bottom of the engine. During engine operation, the pump is used to deliver oil from the sump to the working portion of the engine to lubricate the engine moving parts and provide other functions. Lubrication fluid is constantly supplied to these moving parts, and the lubrication fluid returns to the oil pan through various paths by gravity flow. Cylinders and other components in an internal combustion engine need to be lubricated by oil or other suitable fluid to enable proper operation.
In order to maintain the engine in normal operation, the lubricating fluid must be replaced periodically. Capacitors have been developed to increase the amount of lubrication fluid stored by the engine, thereby increasing the time interval between maintenance events to replace the lubrication fluid. Some examples of oleaginous capacitors are provided in U.S. patent No. 5,479,886, incorporated herein by reference. However, the duration of the maintenance event to replace the lubrication fluid increases as the lubrication fluid must be waited for to leak or drain from the capacitor. The oleaginous capacitor may not even be discharged during a maintenance event. Accordingly, further improvements in lubrication fluid drainage and maintenance are needed.

Detailed Description
For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended, such alterations and further modifications of the illustrated embodiments, and such further applications of the principles of the invention as illustrated herein being contemplated as would normally occur to one skilled in the art to which the invention relates.
Referring to fig. 1, an internal combustion engine system 100 includes an internal combustion engine 102 having a cylinder block 104, the cylinder block 104 housing and/or supporting a plurality of components 106 commonly found on internal combustion engines, such as one or more crankshafts, a plurality of cylinders, pistons, gears, pumps, housings, turbines, and the like. The system 100 also includes a lubrication fluid storage system 120 mounted on the engine to receive lubrication fluid (such as oil) from at least one of the components 106 and return the lubrication fluid to the plurality of components 106 for lubrication and/or cooling.
The internal combustion engine 102 may be any type of internal combustion engine requiring lubrication, including at least a diesel engine, a gasoline engine, or a natural gas engine, and/or combinations thereof. The internal combustion engine 102 may include a single cylinder bank, a dual cylinder bank, or other cylinder bank arrangement. For the internal combustion engine 102, any number of cylinders and cylinder arrangements are contemplated.
With further reference to fig. 2-3, the lubrication fluid storage system 120 includes a primary storage volume 122 and a secondary storage volume 124 that each store lubrication fluid that returns (as indicated by arrow 126) from the component 106 through various channels by gravity. The main storage volume 122 may include, for example, a crankcase and/or an oil pan of the engine 102. The secondary storage volume 124 may include, for example, a fluid capacitor that provides additional volume for lubrication fluid storage to achieve an extended time interval between lubrication fluid changes than can be achieved if only the primary storage volume 122 is available for lubrication fluid storage.
The secondary storage volume 124 may include one or more secondary storage volumes 124a, 124b, 124c that are coupled together by drain paths 128a, 128b that connect bottom ends 130a, 130b, 130c of the secondary storage volumes 124a, 124b, 124c, as shown in fig. 1. At least one of the secondary storage volumes 124a is fluidly connected to a first fluid flow path 132, the fluid flow path 132 being associated with a filtration device 134, such as a cartridge oil filter. The filter device includes a valve 136 that generally separates the first fluid flow path 132 from a second fluid flow path 138 that is in fluid communication with the main storage volume 122.
As shown in fig. 2-3, the secondary reservoir volume 124 is located in an oil drain chamber 140 of the cylinder 104 above the primary reservoir volume 122. The secondary storage volume 124 includes a main wall 142 connected to the cylinder 104 at a bottom end 144. The main wall 142 angles outwardly from the cylinder 104 in an "L" or "J" shape and extends to an upper end 146 of the main wall 142. The upper end 146 forms a weir that provides an overflow path for lubrication fluid to flow from the secondary storage volume 124 to the primary storage volume 122. The main wall 142 is spaced inboard from the cylinder wall 170 such that a blow-by passage 172 is provided for blow-by gas, as indicated by arrow 174.
The secondary storage volume 124 also includes a dividing wall 150 between the cylinder 104 and the main wall 142 that divides the storage volume 124 into a first portion 156 and a second portion 158. Lubrication fluid 160 discharged from the component 106 flows into the first portion 156. The upper end of the partition wall 150 may include a cap 154 that prevents the flow of lubrication fluid into the second portion 158. The partition wall 150 includes a lower end 152 that is spaced apart from the main wall 142 to form an opening so that lubrication fluid may flow from a first portion 156 to a second portion 158 of the second storage volume 124, as indicated by arrow 162. When sufficient lubrication fluid has accumulated in the secondary storage volume 124, the lubrication fluid flows from the second portion 158 and over the weir at the upper end 146, as indicated by arrow 164. During normal operation of the engine 102, the secondary storage volume 124 holds a sufficient amount of lubrication fluid to avoid the crankshaft sinking at start-up.
As can be observed from fig. 2, removal of the drain plug 180 will drain only the lubrication fluid from the main storage volume 122. To drain the secondary storage volume 124, the valve 136 associated with the filter device 134 is removed to unseal the first flow path 132. This allows lubrication from the secondary storage volume 124 to drain through the second flow path 138 leading to the primary storage volume 122, as shown in fig. 3 and indicated by arrow 182. Thus, when the filter device 134 and the associated valve 136 closing the fluid flow paths 132, 138 are removed, substantially all of the lubrication fluid from the secondary and primary storage volumes 124, 122 may be discharged through the opening 184 created by the removal of the plug 180. If multiple secondary storage volumes 124a, 124b, 124c are provided, all of the secondary storage volumes 124a, 124b, 124c are discharged as they are joined by discharge paths 128a, 128b located at the level or plane of the first fluid flow path 132.
