, Description:TECHNICAL FIELD

Present disclosure generally relates to a field of automobiles. Particularly but not exclusively present disclosure relates to an exhaust system of a vehicle. Further, embodiments of the present disclosure discloses an inlet assembly in the exhaust system of the vehicle.

BACKGROUND OF THE INVENTION

Vehicle engines known in the art, may emit a mixture of air pollutants. The air pollutants may be composed of solid material and gaseous material, including particulate matter, nitrogen oxides (NOx), and sulfur compounds. Due to heightened environmental concerns, emission standards have become increasingly stringent over the years. Pollutants emitted from an engine may be regulated depending on the type, size, and/or class of engine. Generally, in modern vehicles, the exhaust systems of engines are equipped with an exhaust after treatment unit such as a diesel particulate filter (DPF), secondary catalytic reduction units, Diesel oxidation catalyst unit, to regulate/remove pollutants exhausted to the environment. Such filters are used to remove the particulate matter including NOx, and sulfur compounds exhausted to the environment from the exhaust flow of the engine.

Exhaust gases which are not circulated effortlessly tend to prevent the free flow of exhaust gases from an outlet manifold of the engine. The usage of filters or other components for purifying the exhaust gases may also create back pressure of exhaust gases in the exhausts system. Exhaust system components such as mufflers and exhaust aftertreatment devices are a source of engine exhaust back pressure. Back pressure in the exhaust system can cause increased emissions, increased fuel consumption, and can negatively affect engine performance. Excessive back pressure in the exhaust systems may also reduce the engine performance.

The exhaust gases that exit the cylinder of the engine are often directed to the exhaust system through the outlet manifold. Generally, a cone assembly is used as an interconnecting member between the outlet manifold and the exhaust system. The cone assembly directs the exhaust gases from the outlet manifold into the exhaust system. The constructional configuration of the conventional cone assemblies often creates a flow path of the exhaust gases where re-circulation of the exhaust gases is rampant. The re-circulation of the exhaust gases within the cone assembly, prevents the free flow of the exhaust gases into the exhaust system. Consequently, the conventional cone assemblies also contribute towards a significant increase in back pressure in the exhaust system.

The present disclosure is directed to overcome one or more limitations stated above or other such limitations associated with the prior arts.

Figure 1 illustrates a front view of an exhaust system (200). The system (200) may include an outlet manifold that is fluidly coupled to one or more outlet ports of at least one cylinder in an engine of a vehicle. The exhaust gases that are generated in the at least one cylinder is directed through one or more outlet ports in the at least one cylinder. The exhaust gases further flow into the outlet manifold. The outlet manifold may further be fluidly coupled to an exhaust pipe (6) for receiving the exhaust gases. The exhaust pipe (6) may accommodate a plurality of ancillary components including but not limited to mufflers, exhaust after treatment units such as a diesel particulate filter (DPF), secondary catalytic reduction units, Diesel oxidation catalyst unit etc. The ancillary components inside the exhaust pipe (6) may contribute towards at least one of optimizing the exhaust noise and reducing the impurities in the exhaust gases. The system (200) may further include an inlet assembly (100) which interconnects the outlet manifold and the exhaust pipe (6). The inlet assembly (100) may direct the exhaust gases from the outlet manifold into the exhaust pipe (6). The configuration of the inlet assembly (100) is explained with greater detail below.

Referring from Figure 2 to Figure 5, the inlet assembly (100) may include a casing (1). The casing (1) in this exemplary and preferable embodiment may be configured in a cylindrical shape. The shape and configuration of the casing (1) must not be considered as a limitation and the casing (1) may be configured of other different shapes. The casing (1) which is of cylindrical shape may also be defined by a circumferential region. The casing (1) may be defined with at least one opening (2) [hereinafter referred to as the opening]. The opening (2) may be defined along the circumferential region of the casing (1). The opening (2) of the casing (1) may be fluidly coupled to a nozzle (7) and an inlet conduit (3). One end of the nozzle (7) may be fluidly coupled to the opening (2) of the casing (1) and the other end of the nozzle (7) may be fluidly coupled to the inlet conduit (3). The inlet conduit (3) may further be fluidly coupled to the outlet manifold extending from the cylinder of the engine. The exhaust gases from the cylinder of the engine may be directed into the casing (1) through the inlet conduit (3) and the nozzle (7) that is fluidly coupled to the casing (1). The exhaust gases initially enter inlet conduit (3) and are further directed through the nozzle (7). The nozzle (7) may be configured to increase the velocity of the exhaust gases and these exhaust gases at high velocity are further directed into the casing (1).

The assembly (100) may include a first plate (4). The first plate (4) may be positioned within the casing (1) and the first plate (4) may be positioned away from the opening (2) at a predetermined position. In this preferable and exemplary embodiment, one of the ends of the casing (1) may be completely closed whereas the other end of the casing (1) which is of the cylindrical shape may be configured with the first plate (4). The casing (1) may be defined by a base area which corresponds to the sides of the casing (1) and the casing (1) may also be defined by a lateral area which corresponds to the circumferential area of the casing (1). One of the base areas of the casing (1) may herein be enclosed whereas the opposite base area may be configured with the first plate (4). As seen from Figure 3, the first plate (4) may be configured to the casing (1) such that the first plate (4) lies along a plane that extends along one of the longitudinal ends of the nozzle (7). Referring to Figure 4, the first plate (4) may also be defined with a plurality of apertures (4a) [hereinafter referred to as the apertures]. The apertures (4a) may be defined on a surface area of the first plate (4). The first plate (4) may also be defined by a central region (8). The central region (8) may herein be defined as a longitudinal section along a substantially central portion of the first plate (4). The apertures (4a) on the first plate (4) may be configured such that the diameter reduces progressively for each of the plurality of apertures (4a) that extend from the central region (8) towards the circumference of the first plate (4). The diameter of the apertures (4a) in the central region (8) may be greater than the diameter of the apertures (4a) in the adjacent regions. The regions that lie adjacent to the central region (8) may also be configured with a substantially longitudinal profile. In an embodiment, the number of apertures (4a) and the diameter of the apertures (4a) in the regions adjacent to the central region (8) may gradually decrease towards the circumference or the end of the first plate (4). In this preferable and exemplary embodiment, the apertures (4a) may be uniformly distributed in multiple columns throughout the surface area of the first plate (4). The diameter of the apertures (4a) in this preferable and exemplary embodiment may be configured to be equal throughout each of the multiple columns. The diameter of the apertures (4a) may be herein configured to vary across the columns whereas the diameter of the apertures (4a) within any given column remains the same. The diameter of the apertures (4a) in the columns defined within the central region (8) may be greater than the diameter of the apertures (4a) defined in the columns adjacent to the central region (8). The diameter of the apertures (4a) may be configured to reduce progressively across columns. The diameter of the apertures (4a) may be configured to reduce progressively and in a symmetrical manner from a central column on the first plate (4) to the columns on either ends that are proximal to the circumference of the first plate (4). In an embodiment, the inlet conduit (3) may be configured as the nozzle and the inlet conduit (3) may be directly coupled to the opening (2) of the casing (1). In an embodiment, the casing (1) may be made of the same material as that of the exhaust pipe (6). The material of the exhaust pipe (6), the inlet conduit (3) and the nozzle (7) must not be considered as a limitation and any suitable material may be employed herein.

The inlet assembly (100) may also include a second plate (5). The second plate (5) may be a non-perforated plate. Further, the second plate (5) may be defined by a proximal end (5a) and a distal end (5b). The second plate (5) may be positioned adjacent to the first plate (4) such that one of the sides of the second plate (5) abuts the first plate (4) whereas the other side of the second plate (5) is proximal to an inner surface of the casing (1). The second plate (5) may be configured to extend along a substantially central region of the first plate (4). The second plate (5) may herein be positioned along a substantially central region of at least one of the inlet conduit (3) and the nozzle (7). As seem from the Figure 3, the second plate (5) extends from the center of the nozzle (7) and extends along the diameter of the casing (1). The second plate (5) may also be positioned to extend along a first axis (A-A) and the first axis (A-A) may be defined to extend along the center of first plate (4). The proximal end (5a) of the second plate (5) may be configured to lie at a substantially central region of the nozzle (7) whereas the distal end (5b) of the second plate (5) may be positioned to lie proximal to the inner surface of the casing (1). The second plate (5) may also be defined with a tapered section (5c). The tapered section (5c) is defined on a side of the second plate (5) that lies opposite to the side of the second plate (5) abutting the first plate (4). Further, the tapered section (5c) may be configured to extend from the distal end (5b) of the second plate (5) for a pre-determined distance. The above-described configuration and positioning of the second plate (5) may divide the casing into a first region (1a) and a second region (1b). In this preferable and exemplary embodiment, the tapered section (5c) may be configured to extend from the distal end (5b) of the second plate (5) to a substantially central region of the second plate (5). In a preferable embodiment, the tapered section (5c) may be configured at an angle of 157 degrees from the longitudinal surface of the second plate (5).

The exhaust gases may initially enter the casing through the inlet conduit (3) and the nozzle (7). The nozzle (7) may be configured to enhance the velocity of the exhaust gases. In this preferable and exemplary embodiment, the nozzle (7) may enhance the flow of exhaust gases to a flow velocity uniformity index that is greater than 0.95. The exhaust gases at high velocity may further enter the casing. The second plate (5) which divides the casing (1) into the first region (1a) and the second region (2b) may divide the exhaust gases into two different flow streams. One of the streams of the exhaust gases may flow into the first region (1a) whereas, the other stream of the exhaust gas may be directed into the second region (1b). Since the second plate (5) is non-perforated, the two different streams of exhaust gases which flow in the first region (1a) and the second region (1b) of the casing (1) are prevented from blending together. Consequently, the re-circulation of exhaust gases or the inter flow of exhaust gases between the first region (1a) and the second region (1b) is prevented. The exhaust gases are subsequently, directed into the exhaust pipe (6) through the apertures (4a) defined on the first plate (4). The exhaust gases from the nozzle (7) may flow into the exhaust pipe (6) through the apertures (4a) at an angle of 90 degrees. The apertures (4a) configured such that the diameter of the apertures (4a) may be configured to reduce progressively and in the symmetrical manner from the central column on the first plate (4) to the columns on either ends that are proximal to the circumference of the first plate (4). The above-illustrated configuration of the apertures (4a) on the first plate (4) ensures that the exhaust gases are efficiently transferred to communicated into the exhaust pipe (6) with minimal back pressure in the casing (1). The apertures (4a) with the larger diameter defined along central columns in the central region (8) of the first plate (4) may circulate the exhaust gases which enter at high velocity into the exhaust pipe (6). The apertures (4a) with the smaller diameter defined adjacent to the central region (8) of the first plate (4) may circulate the exhaust gases which enter at low velocity into exhaust pipe (6). The above-described configuration of the apertures (4a) on the first plate (4) and the non-perforated configuration of the second plate (5) ensures that the exhaust gases are efficiently transferred into the exhaust pipe (6) with minimal re-circulation of the exhaust gases within the casing (1). Consequently, the pressure drop of the exhaust gases within the casing (1) is reduced to less than 35 mbar. Thus, the backpressure on the engine is also reduced and the operational efficiency of the engine is increased. In an embodiment, the above illustrated configuration of the assembly (100) ensures a highly uniform exhaust gas flow distribution across the exhaust pipe (6) with minimal pressure drop. In an embodiment, the above-described assembly (100) improves the oxidation of the nitrous dioxide in the oxidation catalyst. In an embodiment, the improved oxidation reaction over the catalyst surface leads to improved exothermic characteristics. In an embodiment, the improved flow velocity uniformity index that is greater than 0.95 ensures a higher conversion of hydrocarbons and carbon monoxide over the catalyst.

With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.

It will be understood by those within the art that, in general, terms used herein, are generally intended as "open" terms (e.g., the term "including" should be interpreted as "including but not limited to," the term "having" should be interpreted as "having at least," the term "includes" should be interpreted as "includes but is not limited to," etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding the description may contain usage of the introductory phrases "at least one" and "one or more" to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles "a" or "an" limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases "one or more" or "at least one" and indefinite articles such as "a" or "an" (e.g., "a" and/or "an" should typically be interpreted to mean "at least one" or "one or more"); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of "two recitations," without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to "at least one of A, B, and C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B, and C" would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to "at least one of A, B, or C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B, or C" would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase "A or B" will be understood to include the possibilities of "A" or "B" or "A and B."

While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope and spirit being indicated in the description.
