, Description:TECHNICAL FIELD

Present disclosure, in general, relates to the field of automobiles. Particularly, but not exclusively, the present disclosure relates to an intake port in an engine head of a vehicle. Further, embodiments of the present disclosure relates to a swirl inducing configuration of the intake port in the vehicle.

BACKGROUND OF THE INVENTION

An engine block of the internal combustion engine includes one or more cylinders and a cylinder head attached to the cylinder/engine block to close the top portion of the cylinders. The engine block and the cylinder head are generally formed as aluminum or iron castings. Further, the cylinder head of the internal combustion engine may be defined with a plurality of intake ports and exhaust ports. The intake ports may facilitate the flow of air and fuel mixture into the cylinder. The exhaust ports may facilitate the outward flow of exhaust gases which are generated after combustion of the air and fuel mixture inside the cylinder. Further, the flow of air-fuel mixture into the cylinder and the flow of exhaust gases out of the cylinder may be regulated by an intake valve and an exhaust valve respectively. The intake valve and the exhaust valve may be connected to a valve inlet and a valve outlet respectively, which are defined on the cylinder head. Further, the intake port and the exhaust port may be fluidly connected to the intake valve and the outlet valve. The intake port and the exhaust port may be operated between an open position and a closed position for allowing the air-fuel mixture into cylinder through the intake port and for allowing the exhaust gases to flow out of the cylinder through the exhaust port.

The intake ports in the cylinder head play a crucial role in the efficient combustion of the air-fuel mixture inside the cylinder. The design and the configuration of the intake port plays a major role in enhancing the flow of fluid into the cylinder and thereby ensures a complete combustion process. The conventional intake ports are designed to induce a rotational motion of the incoming air-fuel mixture in a plane along an axis that is perpendicular to the cylinder. This type of rotational motion of the air-fuel mixture is generally referred to as a tumble flow of air-fuel mixture. However, inducing a tumble flow of air-fuel mixture is generally not sufficient for the complete combustion of the air-fuel mixture. Further, inducing only the tumble flow of air-fuel mixture in the cylinder may offer less turbulence to the air-fuel mixture. Consequently, inefficient combustion takes place in the cylinder and the overall operational efficiency of the engine is reduced.

The present disclosure is directed to overcome one or more limitations stated above or any other limitations associated with the conventional configuration of intake ports.

SUMMARY OF THE DISCLOSURE

Figure 1 illustrates a perspective view of an engine head (300), and reference is made to Figure 1 to Figure 3. The engine head (300) may be mounted on a cylinder of an internal combustion engine. The engine head (300) may be defined by at least one inlet valve port (7) [hereinafter referred to as the inlet valve port] and at least one outlet valve port (8) [hereinafter referred to as the outlet valve port]. The inlet valve port (7) and the outlet valve port (8) may be through provisions that are defined to the engine head (300). Further, each of the inlet valve port (7) may accommodate an inlet valve (5) and each of the outlet valve port (8) may accommodate an outlet valve (9). The inlet valve (5) and the outlet valve (9) may be configured to operate between an open position and a closed position. Further, the inlet valve port (7) may be fluidly connected to an intake port (100) and the outlet valve port (8) may be fluidly connected to an exhaust port (200). The intake port (100) may direct a fluid mixture into the cylinder through the inlet valve port (7). The inlet valve may be operated to the open condition and the fluid from the intake port (100) may flow into the cylinder through the inlet valve port (7). Subsequently, combustion of the fluid may take place inside the cylinder and the spent gases, also referred as exhaust gases, may exit the cylinder through the outlet valve port (8) and the exhaust port (200). The outlet valve (9) may be operated to release the exhaust gases from the cylinder into the exhaust port (200).

In an embodiment, the configuration of the engine head (300) may must not be limited to the above-illustrated arrangement. The cylinder head (300) may also be configured to include components such as spark plugs which may be based on the type of fuel injected within the cylinder. Further, the configuration of the inlet valve port (7), the outlet valve port (8), the inlet valve (5) and the outlet valve (9) must not be limited to the above-described arrangement. Any known configuration of the inlet valve port (7), the outlet valve port (8), the inlet valve (5) and the outlet valve (9) may be configured to the engine head (300). In an embodiment, the angular positioning of the intake port (100) and the exhaust port (200) must not be limited to the above illustrated arrangement and any known orientation which enhances the flow of fluid through the intake port (100) and the exhaust port (200) may be adapted. Further, the configuration of the intake port (100) that induces a swirling flow to the fluid through the intake port (100), is explained with greater detail below.

The intake port (100) may be fluidly connected to the inlet valve port (7) and the inlet valve (5) may regulate the flow of fluid into the cylinder by opening or closing the inlet valve port (7). The intake port (100) may be defined by a fluid intake channel (1). One end of the fluid intake channel (1) may be fluidly coupled to the inlet valve port (7) and the other end of the fluid intake channel (1) may be defined by a fluid inlet port (6).

In an embodiment, the fluid inlet port (6) may be fluidly connected to an intake manifold. The air drawn from the atmosphere may be directed through the intake manifold and to the intake port (100). In an embodiment, the shape and configuration of the fluid intake channel (1) may be circular. However, the circular shape of the fluid intake channel (1) must not be considered as a limitation and any shape which enhances/generates the required turbulence to the flow of the fluid may be configured for the fluid intake channel (1). In an embodiment, the fluid intake channel (1) may be defined in the engine head (300) by any known method of manufacturing, including but not limited to casting.

With reference to Figure 4 and Figure 5, at least one plate (2) [hereinafter referred to as the plate] may be positioned within the fluid intake channel (1). The configuration of the plate (2) is described in detail. The plate (2) may be defined by a first end (2a), a second end (2b) and a central section (2c). The first end (2a) of the plate (2) may be a region that is positioned proximal to the fluid inlet port (6) and the second end (2b) of the plate (2) may be a region of the plate (2) that is positioned proximal to the inlet valve port (7). Further, the central section (2c) of the plate (2) may extend between the first end (2a) and the second end (2b) of the plate (2). In a preferable and an exemplary embodiment, the plate (2) may be defined with a twisted profile. The twisted profile may be defined along the central section (2c) of the plate (2) and the twisted profile of the central section (2c) may range from an angle of 170 degrees to 190 degrees. Further, the first end (2a) and the second end (2b) of the plate (2) in this preferable and exemplary embodiment may be configured to lie parallel to each other and along the same plane whereas, the central section (2c) may be configured with the twisted profile at the angle of 180 degrees. Further, the dimensions of the plate (2) may be configured to be equivalent to the width of the fluid intake channel (1). The width of the plate (2) with the twisted profile may be equivalent to the diameter of the fluid intake channel (1). Further, the plate (2) may be positioned at a pre-determined distance away from the inlet valve port (7). The second end (2b) of the plate (2) may be positioned away from the inlet valve port (7). The pre-determined distance at which the second end (2b) of the plate (2) and the inlet valve port (7) may range from 8% to 12% of the diameter of the fluid intake channel (1). In this preferable and exemplary embodiment, the plate (2) is positioned in the fluid intake channel (1) such that the second end (2b) of the plate (2) is at the pre-determined distance which is equal to 10% of the diameter of the fluid intake channel (1).

In another embodiment, two plates (2) may be positioned in the fluid intake channel (1). The two plates (2) may be herein referred to as a first plate (2) and a second plate (2). As described above, the first plate (2) and the second plate (2) may also be defined with the twisted profile. Further, the first plate (2) and the second plate (2) may also be configured to be positioned at the pre-determined distance from the inlet valve port (7) that ranges from 8% to 12% of the diameter of the fluid intake channel (1) as described above. Further, the combined width of the first plate (2) and the second plate (2) in this embodiment may be equivalent to the overall width of the fluid intake channel (1).

In an embodiment, the plate (2) may be positioned inside the fluid intake channel (1) by any known processes including but not limited to welding, shrink fitting etc. pores, protrusions on the plate. In an embodiment, the plate (2) may be defined with fluid channeling protrusions. The fluid channeling protrusions may protrude from the central section (2c) of the plate (2) and the fluid channeling protrusions may assist in inducing the turbulence to the flow of fluid through the fluid intake channel (1).

In an embodiment, the configuration of the plate (2) with the twisted profile of the central section (2c) at the angle of 180 degrees, may induce a swirling flow to the fluid flowing through the fluid intake channel (1). The configuration of the plate (2) imparts turbulence to the flow of fluid and also induces the swirling flow to the fluid. The fluid may be subsequently directed into the cylinder through the inlet valve port (7). The fluid inside the cylinder may swirl in a circular motion and the circular swirl of the fluid may be around an axis that extends through the length of the cylinder. In an embodiment, the swirling flow to the fluid ensures efficient combustions inside the cylinder. Consequently, the overall operational efficiency of the engine is improved and the concentration of toxic gases in the exhaust gases is also reduced.

In an embodiment, the fluid intake channel (1) may be configured to induce a tumble flow to the fluid flowing through the fluid intake channel (1). The tumble flow of the fluid may be the flow of fluid along a direction that is perpendicular to the axis of the cylinder that extends along the length of the cylinder. Further, the above-described plate (2) may be positioned into the fluid intake channel (1) and the fluid may be imparted with the combination of the tumbling and swirling flow. Consequently, the overall operational efficiency of the engine is improved.

In an embodiment, the plate (2) is positioned such that the distance of the second end (2b) of the plate (2) from the inlet valve port (7) is in the range from 8% to 12% of the diameter of the fluid intake channel (1). Consequently, the positioning of the plate (2) in the fluid flow channel ensures that the swirling flow is imparted to the fluid before the fluid enters the cylinder. Thus, the swirling flow of fluid into the cylinder is uniformly distributed. Further, the positioning of the plate (2) in the fluid intake channel (1) at the pre-determined distance from the inlet valve port (7) as described above, ensures that pressure waves are not generated at the inlet valve port (7) and there is less blockage to the flow of fluid into the cylinder. Consequently, the overall operational efficiency of the engine is improved and the concentration of toxic gases in the exhaust gases is also reduced.

Equivalents

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.
