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

TECHNICAL FIELD
Embodiments of the present disclosure generally relate to automotive vehicles and more particularly embodiments relates to a four point mounting systems of engine.
BACKGROUND OF THE INVENTION
Automotive vehicles, such as cars, typically comprise frame, also referred to as chassis, which provides a primary support structure to the vehicle. A majority of components, such as an internal combustion engine, transmission and the like, are mounted directly on the chassis. It is known to those skilled in the art relating to heavy duty engine-transmission combinations to provide a four point power train mounting arrangement for mounting heavy duty engine-transmission on the chassis. Typically, in a four point power train mounting arrangement, two mounting pads may be located on the sides or front end of the engine and are connected through brackets to the vehicle frame. In such conventional engine mounting arrangements, the engine mounting brackets which are mounted on the C-section of the frame (also referred to as a “long member”) are mounted inside of C-Section of frame. Such mounting of the engine mounting brackets on the C-section of the frame limits the available space between the two long members.
In light of forgoing discussion, it is necessary to provide a reliable, cost effective and cost effective engine mounting arrangement to overcome the limitation stated above.
OBJECTS OF THE INVENTION
The objective of invention is to provide a reliable, simple and cost effective, engine mounting arrangement.
Another objective of the invention is to provide an engine mounting arrangement that limits transmission of vibrations from the engine and transmission.

Yet another objective of the invention is to provide an engine mounting arrangement that enables quick and convenient removal of the engine from the chassis.
Further objects and features of the invention will become apparent from the following detailed description when considered in conjunction with the drawings.

DETAILED DESCRIPTION OF THE INVENTION
Referring now to the drawings wherein the showings are for the purpose of illustrating a preferred embodiment of the invention only, and not for the purpose of limiting the same. FIG. 1 illustrates a front perspective view of an engine mounting arrangement 100, according to an embodiment of the present disclosure. The engine mounting arrangement

100 (also referred to as “mounting arrangement 100”) may be employed for mounting an engine 102 on a vehicle (not illustrated). The engine 102 may be a heavy internal combustion engine and the vehicle may be a commercial vehicle, a car, an SUV (Sports Utility Vehicle), or any other automobile without deviating from the spirit of the invention. The vehicle, as would be apparent to those skilled in the art, includes a body (or frame/sub-frame) carrying a set of wheels, the engine 102 being adapted to drive the wheels through a transmission system for moving the vehicle on a surface, such as a road, in a known manner.
The engine 102 is mounted on a chassis 104 of the vehicle. As best shown in FIG. 1, a pair of brackets assemblies 106, 108 support a front portion 110 of the engine 102 on a front horizontal member 112 of the chassis 104, in a manner known to those skilled in the art. Referring now to FIG. 2 which illustrates another perspective view of the engine 102 mounted on the chassis 104 with the engine mounting arrangement 100 of FIG. 1, the chassis 104 of the vehicle includes a pair of longitudinal members 114, 116 connected by horizontal members such as the front horizontal member 112. Each longitudinal member of the pair of longitudinal members 114, 116 typically has a C-shaped cross section wherein the open portions of the C-shaped cross sections being positioned towards each other.
A first set of brackets is removably connected to the longitudinal members 114, 116 of the chassis 104. Specifically, a first bracket 118 of the first set of brackets is connected to the longitudinal member 114, and a second bracket 120 of the first set of brackets is connected to the longitudinal member 116. The first bracket 118 of the first set of brackets may be identically to the second bracket 120. In one embodiment of the present disclosure, the first bracket 118 of the first set of brackets is connected to the longitudinal member 114, by a fastener arrangement, such as by a nyloc nut and hex screw. Similarly, the second bracket 120 of the first set of brackets is connected to the longitudinal member 116, by a fastener arrangement, such as by a nyloc nut and hex screw. Therefore the first bracket 118 and the second bracket 120 is removably connected to the respective longitudinal member. Both the first bracket 118 (best shown in FIG. 3A) and the second bracket 120 may be L-shaped i.e. they have an L-shaped configuration. The first bracket

118 of the first set of brackets upon connected to the longitudinal member 114 is in alignment with the second bracket 120 of the first set of brackets connected to the longitudinal member 116.
A set of elastomeric buffers are removably connected to the first set of brackets 118, 120. Specifically, an elastomeric buffer 122 (best shown in FIG. 3C) is provided on top of the first bracket 118, and an elastomeric buffer 124 is provided on top of the second bracket 120. The elastomeric buffer 122 may be structurally identical to the elastomeric buffer 124. In one embodiment of the present invention, the set of elastomeric buffers are a pair of rubber buffers. The rubber buffers are bolted on the first bracket 118 and the second bracket 120.
Referring again to FIG. 2, the engine mounting arrangement 100 further includes a second set of brackets. The second set of brackets is removably connected to peripheral portion of a portion on the flywheel 126 of the engine 102 of the automobile. The second set of brackets also includes a first bracket 128 (Best shown in FIG. 3B) and a second bracket 130. The first bracket 128 and the second bracket 130 are connected to distant points on the flywheel 126 of the engine 102 of the automobile. The first bracket 128 and the second bracket 130 may be provided with a rib, for imparting strength thereto. As per the present embodiment of the invention, the first bracket 128 may be identical to the second bracket 130.
The second set of brackets are adapted to connected to the first set of brackets through the set of elastomeric buffers provided on the first set of brackets. Specifically, the first bracket 124 of the second set of brackets may be connected to the first bracket 118 of the first set of brackets through the elastomeric buffer 122. Similarly, the second bracket 130 of the second set 126 of brackets may be connected to the second bracket 120 of the first set of brackets through the elastomeric buffer 122.
The first bracket 128 of second set of brackets being connected to the first bracket 118 of the first set of brackets through the elastomeric buffer 122 holds the engine 102 on longitudinal members of the chassis. The second bracket 130 of the second set of

brackets being connected to the second bracket 120 of the first set of brackets through the elastomeric buffer 124 holds the engine 102 on longitudinal members of a chassis. The set of elastomeric buffers 122 and 124, being adapted to limit transmission of vibration from first set of brackets to the second set of brackets, therethrough.
The foregoing description provides specific embodiments of the present invention. It should be appreciated that these embodiment are described for purpose of illustration only, and that numerous other alterations and modifications may be practiced by those skilled in the art without departing from the spirit and scope of the invention. It is intended that all such modifications and alterations be included insofar as they come within the scope of the invention as claimed or the equivalents thereof.
