APPLICANT
TVS MOTOR COMPANY LIMITED, an Indian company, having its address at “Chaitanya”, No.12 Khader Nawaz Khan Road, Nungambakkam, Chennai 600 006.

PREAMBLE TO THE DESCRIPTION
The following specification particularly describes the invention and the manner in which it is to be performed.

FIELD OF THE INVENTION
[001] The present invention relates to a two-wheeled vehicle, more particularly, relates to an oil cooler for an internal combustion engine for the two-wheeled vehicle.

BACKGROUND OF THE INVENTION
[002] In recent past, two-wheeled vehicles are typically provided with engine lubrication systems that use an internal circulation system for flow of a lubricant such as oil. The internal circulation system employs an oil pump for pumping oil from an oil tank to a main oil delivery channel in the engine, and then the oil delivery main channel is divided into few critical channels such as a piston, a crankshaft and a bearing, a valvetrain system and a transmission.
[003] Further, the engine generates heat during generation of motive force. The heat generated within the engine is required to be dissipated for optimum operation of the engine. When the engine remains at a high temperature for a prolonged duration of time, viscosity of the oil is reduced, which reduces the lubrication to the engine. Consequently, resulting in damage to mechanical parts and hence the output efficiency of the engine is reduced, inherently affecting the service life of the engine. In order to dissipate the heat generated in the engine, an engine oil cooling device is placed in between the lubrication path through a conveying pipe.
[004] In a conventional engine oil cooling device, engine oil is used for lubrication as well as a cooling medium. The lubricating properties of the oil change due to excessive heat, resulting in drop of engine performance and durability. Also, the engine is typically force cooled at its top portion i.e., cylinder head and cylinder block, where the combustion occurs. However, rate of heat transfer at the combustion zone is not effective.
[005] Typically, a separate oil cooling assembly, like radiator or oil cooler may be used for cooling the oil. However, such an assembly increases the part count in the engine, consequently, increasing size of the engine. Also, additional load on the engine affects its performance.
[006] Further, conventional engine oil cooling device provides a zig-zag oil path in its inner side of a cylinder head cover for oil cooling. However, as the cylinder casing, the cylinder head, the piston and the valve are already in a high temperature zone of the engine, a large thermal stress is thereby induced. Such heat is transferred to the zig-zag oil path as well. As such, instead of oil being cooled, the oil gets heated, thereby decreasing its viscosity, greatly reducing its lubrication characteristics. Consequently, resulting in damage to mechanical parts, leading to decrease in efficiency of the engine and also affecting service life of the engine.
[007] Additionally, in order to improve the heat dissipation effect in the engine, a large number of heat sinks are arranged outside the cylinder head or the cylinder head cover. However, such installations make the construction complex, which increases the cost and its maintenance.
[008] Furthermore, attempts have been made for providing an external oil cooler in the front portion of the vehicle between the engine and below the head tube so that ambient air when passes through the oil cooler during vehicle motion. The oil passing through the tubes disposed in between the external oil cooler is cooled due to the flow of ambient air on the oil cooler. However, such oil coolers include a single integrated structure with no multiple plates, which is cost intensive, difficult to manufacture, cumbersome and heavy. Also, the conventional oil coolers are provided with vertical fins which results in a lesser contact surface area with the ambient air, consequently resulting in reducing the cooling efficiency of the oil cooler device. Additionally, oil tubes disposed in such single integrated structure results in providing lesser contact surface area with the ambient air, due to smaller dimensions of the tubes, inherently affecting cooling efficiency of the oil cooler device.
[009] In view of the above, there is a need for an oil cooler for an internal combustion engine, which addresses one or more limitations stated above.

As such, the end 118a is provided below the partition wall 204a (or at the bottom portion of the crankcase 208) and the end 120a is provided above the partition wall 204a.
[037] In an embodiment, the features in the crankcase 208 i.e. the partition wall 204a and the lubricant passage 206 are interchangeably used for sump 204 and the crankcase 208 in the premise that the crankcase 208 is the sump 204.
[038] In an embodiment, each of the inlet port 108 and the outlet port 110 are provided with a mounting 130 (as shown in Figure 7) for facilitating mounting of the inlet pipe 118 and the outlet pipe 120 respectively.
[039] Further, a plurality of vent holes 114 are provided to the first plate 102 and the second plate 104.

[040] Additionally, a gasket member 116 is disposed between the first plate 102 and the second plate 104. The gasket member 116 is adapted to seal leakage of the lubricant flowing in the flow path 106. The gasket member 116 is provided with beadings 116a, which are adapted to seal leakage of the lubricant flowing in the flow path 106. As such, the beadings 116a conform to the shape and configuration of the flow path 106, and this engage with the inner surfaces 102a, 104a. Thus, the beadings 116a are also provided on both the surfaces of the gasket member 116. In an embodiment, the beadings 116a are made of suitable sealing material such a rubber material or any other suitable material as per sealing requirement. Further, the gasket member 116 is provided with slots 122 for enabling air flow between the first plate 102 and the second plate 104. As such, the slots 122 align with the vent holes 114 provided to the first plate 102 and the second plate 104.
[041] In the present embodiment, the first plate 102, the second plate 104 and the gasket member 116 are rectangular shaped members and are dimensioned to form a rectangular structure. Alternatively, the shape, configuration, and dimensions of each of the first plate 102, the second plate 104 and the gasket member 116 can be selected as per design feasibility and requirement of the oil cooler 100.
[042] Furthermore, a plurality of fin members 112 are defined on at least one of the first plate 102 and the second plate 104. Each fin member 112 is spaced apart from one another. In an embodiment, the fin members 112 extend horizontally on the first plate 102 and the second plate 104, and each of the fin member 112 are spaced apart vertically. In an embodiment, the plurality of fin members 112 extend uniformly or may vary in thickness during horizontal extension on the first plate 102 and the second plate 104. In another embodiment, the plurality of fin members 112 may also form a corrugated configuration (not shown) on the first plate 102 and the second plate 104 during horizontal extension for improving the surface area available for ambient air contact. As such, the construction or configuration of the plurality of fin members 112 is selected as per feasibility and requirement. In an embodiment, the plurality of fin members 112 are defined on at least one of an outer surface 102b of the first plate 102 and an outer surface 104b of the second plate 104.
[043] Further, the plurality of vent holes 114 are defined between each of the fin member 112 to enable air flow through the first plate 102 and the second plate 104 for cooling the heated lubricant. Thus, the oil cooler 100 is adapted to enable cooling of the lubricant. In the present embodiment, the lubricant is engine oil. In another embodiment, the engine 202 is a naturally aspirated engine or an air-cooled engine.
[044] In an embodiment, as depicted in Figure 9, the construction of the oil cooler 100 ensures greater contact with the ambient air, thereby improving cooling characteristics of the oil cooler 100 (depicted as ‘t2’) vis-à-vis the cooling characteristics of a conventional oil cooler (depicted as ‘t1’).
[045] In an embodiment, the first plate 102 and second plate 104 are made of a metallic material or a composite material, which facilitates heat dissipation or transfer. In an embodiment, the gasket member 116 can be made of a metallic material, a non-metallic material or a composite material, as per design feasibility and requirement.
[046] Advantageously, the present disclosure provides the oil cooler 100 which provides an improved cooling effect to the lubricant or engine oil flowing in the engine 202. Consequently, improving engine life, durability and performance. Also, the construction of the outlet pipe 120 from the oil cooler 100 ensures routing of the cooled lubricant direct to lubricant passage 206 which routes the cooled lubricant to engine components such as the crankshaft and the piston. Further, due to the cooling effect, the oil reusability and lubrication of the engine 202 is improved. Further, the oil consumption rate is considerably reduced due to the oil cooler 100.
