The following specification particularly describes and ascertains the nature of this invention and the manner in which it is to be performed:-

TECHNICAL FIELD
[001] The embodiments herein generally relate to oil pan in internal combustion engines and more particularly but not exclusively to oil pan for cooling the oil in the engine.

BACKGROUND
[002] Generally, an oil cooler is a heat exchanging device used to reduce the temperature of the oil used for cooling and lubrication of an engine.
[003] Conventionally, an oil cooler is mounted to a cylinder block of the engine and is usually placed on pressure line of oil circuit. Hence, pressure drop across the aforementioned oil cooler is considerably high and thereby causing loss in main oil gallery pressure. The low oil pressure in the main oil gallery accelerates the wear rate of engine bearings.
[004] Therefore, there exists a need to eliminate the high pressure drop across the oil cooler and to improve the main oil gallery pressure of the engine. Furthermore, there exists a need for a system having an oil cooler that can eliminate the aforementioned drawbacks.

OBJECTS
[005] The principal object of an embodiment of this invention is to provide an oil pan integrated with an oil cooler of the engine.
[006] Another object of an embodiment of this invention is to eliminate the high pressure drop across the oil cooler and to improve main oil gallery pressure of an engine.
[007] The objects of the embodiments herein will be better appreciated and understood when considered in conjunction with the following description and the accompanying drawings. It should be understood, however, that the following descriptions, while indicating embodiments and numerous specific details thereof, are given by way of illustration and not of limitation. Many changes and modifications may be made within the scope of the embodiments herein without departing from the spirit thereof, and the embodiments herein include all such modifications.

BRIEF DESCRIPTION OF DRAWINGS
[008] The embodiments of this invention are illustrated in the accompanying drawings, throughout which like reference letters indicate corresponding parts in the various figures. The embodiments herein will be better understood from the following description with reference to the drawings, in which:
[009] FIG. 1 depicts a perspective view of the oil pan assembly, according to an embodiment of the invention as disclosed herein;
[0010] FIG. 2 depicts a top view of the oil pan assembly, according to an embodiment of the invention as disclosed herein; and
[0011] FIG. 3 depicts an engine assembled with the oil pan assembly, according to an embodiment of the invention as disclosed herein.

DETAILED DESCRIPTION
[0012] The embodiments herein and the various features and advantageous details thereof are explained more fully with reference to the non-limiting embodiments that are illustrated in the accompanying drawings and detailed in the following description. Descriptions of well-known components and processing techniques are omitted so as to not unnecessarily obscure the embodiments herein. The examples used herein are intended merely to facilitate an understanding of ways in which the embodiments herein may be practiced and to further enable those of skill in the art to practice the embodiments herein. Accordingly, the examples should not be construed as limiting the scope of the embodiments herein.
[0013] The embodiments herein achieve an oil pan integrated with an oil cooler of the engine. Referring now to the drawings, and more particularly to FIGS. 1 through 3, where similar reference characters denote corresponding features consistently throughout the figures, there are shown embodiments.
[0014] FIG. 1 depicts a perspective view of the oil pan assembly, according to an embodiment of the invention as disclosed herein. FIG. 2 depicts a top view of the oil pan assembly, according to an embodiment of the invention as disclosed herein. The oil pan assembly 100 includes an oil pan 102 and an oil cooler 104. The oil pan 102 is used for collecting or storing the oil (not shown) used for lubricating and/or cooling the engine 200.
[0015] The oil cooler 104 is used for cooling the oil (not shown) used for lubricating and/or cooling the engine 200. The oil cooler 104 is a conduit having at least one inlet (not shown) and at least one outlet (not shown). In an embodiment the inlet (not shown) of the oil cooler 104 is used for entry of a coolant (not shown) and the outlet (not shown) is used for exit of the coolant (not shown). In an embodiment, the oil cooler 104 is provided and connected at the bottom of the oil pan 102 thereby even during low oil level, the oil cooler 104 extracts the heat from the oil stored in the oil pan 102.
[0016] In an embodiment, the oil pan assembly 100 includes one oil cooler 104. However, it is also within the scope of the invention to provide plurality of oil cooler 104 without otherwise deterring the intended function of the oil pan assembly 100 as can be deduced from the description. In an embodiment, the oil cooler 104 has circular cross section. However, it is also within the scope of the invention to provide the oil cooler 104 with rectangular cross section or any other cross section without otherwise deterring the intended function of the oil cooler 104 as can be deduced from the description.
[0017] FIG. 3 depicts an engine assembled with the oil pan assembly, according to an embodiment of the invention as disclosed herein. The working of the oil pan assembly 100 is as follows. As and when the engine 200 is in operation, the hot oil from the engine 200 is collected by the oil pan 100. The coolant (not shown) from the engine 200 enters the oil cooler 104 via inlet (not shown) of the oil cooler 104 and the coolant absorbs the heat from the oil, since the oil in the oil pan 104 is in contact with the oil cooler 104 and the coolant exits from the oil cooler 104 through the outlet (not shown) of the oil cooler 104. Thus the oil is cooled using the oil pan assembly 100.
[0018] The foregoing description of the specific embodiments will so fully reveal the general nature of the embodiments herein that others can, by applying current knowledge, readily modify and/or adapt for various applications such specific embodiments without departing from the generic concept, and, therefore, such adaptations and modifications should and are intended to be comprehended within the meaning and range of equivalents of the disclosed embodiments. It is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation. Therefore, while the embodiments herein have been described in terms of preferred embodiments, those skilled in the art will recognize that the embodiments herein can be practiced with modification within the spirit and scope of the embodiments as described herein.
