DETAILED DESCRIPTION

[00010] Various features and embodiments of the present invention here will be discernible from the following further description thereof, set out hereunder. According to an embodiment, an exhaust assembly for automotive and non-automotive application. As per an embodiment, such exhaust assembly is installed in a saddle type vehicle. It is contemplated that the concepts of the present invention may be applied to other types of vehicles employing the similar transmission within the spirit and scope of this invention. Further "front" and "rear", and "left" and "right" referred to in the ensuing description of the illustrated embodiment refer to front and rear and left and right directions as seen from a rear portion of the vehicle and looking forward. Furthermore, a longitudinal axis (L-L’) unless otherwise mentioned, refers to a front to rear axis relative to the vehicle, while a lateral axis (C-C’) unless otherwise mentioned, refers generally to a side to side, or left to right axis relative to the vehicle.
[00011] However, it is contemplated that the disclosure in the present invention may be applied to non-automotive application like generators without defeating the spirit of the present subject matter. The detailed explanation of the constitution of parts other than the present invention which constitutes an essential part has been omitted at suitable places.
[00012] Typically, air fuel mixture is supplied to an internal combustion (IC) engine by means of an intake system. Thereafter, combustion of the air fuel mixture takes place so that a piston disposed in the internal combustion (IC) engine is set into motion. The piston is operated in a linear motion, after which said liner motion is converted to a rotational motion, wherein said rotational motion is transferred to a rear wheel finally resulting into motion of the vehicle. This mechanism also results in generation of power and torque by the internal combustion (IC) engine. The exhaust gases produced after combustion is expelled from the internal combustion (IC) engine through an exhaust port which facilitates the movement of the exhaust gases to an exhaust assembly. The unburnt hydrocarbons in the exhaust gases are oxidized as it passes through a catalytic converter and there is reduction in noise as it passes through a muffler unit and is later released in the atmosphere.
[00013] Generally, the exhaust gases enter the exhaust assembly through an exhaust pipe assembly after which it passes through the catalytic converter for conversion, and finally enter the baffle assembly within the muffler unit. In the baffle assembly the gases pass through a bend pipe and are released through a set of perpetrating holes formed at its end. The gases finally enter a baffle pipe before being emitted into the atmosphere through a tail pipe. This whole process provides a better diffusion of the gases so that the noise is dampened, and a better sound quality is provided. The catalytic converter functions to reduce the harmful carbon monoxide and unburnt hydrocarbons in the exhaust gas to carbon dioxides by catalysing it using a catalyst by a redox reaction. The catalytic converter has in its inner structure arranged in the form of dense honeycomb structure so that the exhaust gases touch a bigger area of catalyst so that they are converted more quickly and efficiently. The catalyst is usually rare earth metals such as platinum to convert the exhaust gases.
[00014] In many applications, particularly the saddle type vehicles where there is little room for mounting exhaust assembly. Hence, the space to accommodate the catalytic converter is constrained. To obtain necessary performance of the catalytic converter, the catalytic converter should be of certain predetermined length and have a predetermined surface area of contact for most optimum performance of the catalytic converter. However, due to space and layout constraints in saddle type vehicle lengthier catalytic converter is not possible. Further, to optimize the performance longer catalytic converter is detrimental from the point of view pressure loss of exhaust gases between the upstream end and downstream end of the catalytic converter.
[00015] A solution to the problem is to use two catalytic converters, namely first catalytic converter and a second catalytic converter. The first catalytic converter is disposed substantially upstream, and the second catalytic converter is disposed substantially downstream taking reference from the cylinder head of the engine. This way, the exhaust gases can be made to come in contact with sufficient surface area of the catalyst to completely catalyse the redox reaction and there is minimal pressure loss of the exhaust gases.
[00016] However, the first catalytic converter location is extremely important as the catalyst within the first catalytic converter starts functioning only when the temperature within the first catalytic converter is high enough and starts to glow red hot. The temperature in which it is achieved is called activation temperature. The goal of any catalytic converter mounting is locating it to achieve the activation temperature as quickly as possible. The first catalytic converter can be disposed upstream closer to the exhaust port; however, this reduces the overall efficiency of the first catalytic converter. This happens mainly due to exposure of the first catalytic converter to high velocity flow of the exhaust gases as high velocity flow of exhaust gases passes through a few portions of the catalytic converter leaving other portion as unutilised. Additionally, the high velocity flow of exhaust gases takes lesser time than the time required for catalysation. Further, positioning of the first catalytic converter near to the exhaust port expose it to high temperature of the exhaust gases. This excessively increase the temperature due to the contact with hot exhaust gases and from the catalytic oxidation of uncombusted hydrocarbons and carbon monoxide and may end up reducing the life of the catalyst. Further, the honeycomb structure within the catalytic converter must withstand rapid temperature changes when the automobile engine is started and stopped. Such operating conditions require the honeycomb structure to have a high thermal resistance which increases cost and can reduce life.
[00017] To address the above issues, it is known to manufacture catalytic converter having bents. However, manufacturing catalytic converter having bents requires special manufacturing operations which increases the overall cost of the subsystem and the vehicle.
[00018] So, it is always a challenge for the automobile designer to design an exhaust assembly which is more efficient, effective & compact meeting various challenges outlined above and at same time be less costly. The trade-off between efficiency and cost is critical aspect for the automobile manufacturers. At the same time the design should be so compact which will adversely require major change in layout of a vehicle. Therefore, an exhaust assembly is proposed in the present subject matter to alleviate one or more drawbacks highlighted above & other known drawbacks in the art.

[00038] The aforesaid and other advantages of the present subject matter would be described in greater detail in conjunction with the figures & embodiment in the following description.
[00039] Figure 1a. illustrates a partial side view of a saddle type vehicle (100) in accordance with one embodiment of the present invention. Figure 1b. illustrates a partial front view of the vehicle (100) according to the embodiment of the present invention. For the sake of brevity, figure 1a and figure 1b will be discussed together. The saddle type vehicle (hereinafter “vehicle”) (100) comprises of a frame assembly (100). The frame assembly (106) comprises of a head tube (not shown), a main tube (not shown), and a pair of side tubes (not shown). The vehicle (100) extends from a front portion (F) to a rear portion (R) in a longitudinal axis (L-L’). An internal combustion (IC) engine (107) is coupled to the frame assembly (106) of the vehicle (100). The IC engine (107) transfers the drive to the rear wheel (not shown) through an endless transmission.
[00040] The internal combustion (IC) engine (107) comprising a cylinder head (107A), a cylinder block (107B) and a crankcase (107C). The internal combustion IC engine (107) comprises a reciprocating piston (not shown) enclosed in the cylinder block (107B), a connecting rod (not shown) connecting the reciprocating piston to a rotatable crankshaft (not shown). During operation, fuel, and air mixture from an induction system (not shown) enter a combustion chamber (not shown) disposed between the cylinder head (107A) and the cylinder block (107B) through an intake port (not shown) disposed on the cylinder head (107A). The burning of fuel and oxidizer occurs in the combustion chamber (not shown) and transfers mechanical energy of the reciprocating piston (not shown) to the rotatable crankshaft (not shown) which generates power due to the slider crank mechanism. In the embodiment of the present invention, the engine operates in four cycles namely, intake stroke, compression stroke, power, and exhaust stroke. Combustion of air fuel mixture occurs at the end of compression stroke and beginning of power stroke, after combustion the hot exhaust gases are generated which are expelled out of the combustion chamber (not shown) during the exhaust stroke to an exhaust port (not shown) within the cylinder head (107A) and is passes to the exhaust assembly (101). The exhaust assembly (101) includes an exhaust pipe assembly (102), a catalytic converter assembly (104), a catalytic converter adaptor assembly (103) and a muffler unit (105). The exhaust pipe assembly (102) includes a first exhaust pipe (102A) and a second exhaust pipe (102B). Further, the catalytic converter assembly (104) includes a first catalytic converter (104A) and a second catalytic converter (104B). Both the catalytic converters (104A & 104B) functions to reduce the harmful carbon monoxide and un-burnt hydrocarbons in the exhaust gas to carbon dioxides by catalyzing it by a redox (reduction and oxidation) reaction. In an embodiment, the catalytic converter adapter assembly (103) includes a first catalytic converter adaptor (103A) and a second catalytic converter adaptor (103B).
[00041] Figure 2. illustrates a perspective view of the exhaust assembly (101) and a localized cut sectional view of the exhaust assembly (101) according to the embodiment of the present subject matter. The first exhaust pipe (102A) is connected to the exhaust port (not shown) and extending to connect with the catalytic converter adapter assembly (103). The first exhaust pipe (102A) is having a bend portion (102AA). The front-end portion (102F) of the first exhaust pipe (102A) has a mounting flange (102M) for mounting to a corresponding mounting surface (not shown) on the cylinder head (107A) (as shown in figure 1) of the internal combustion (IC) engine (101). The second exhaust pipe (102B) connects the second catalytic converter adaptor (103B) with the second catalytic converter (104B). The muffler unit (105) exhausts the high-temperature and high-pressure gases passing through the exhaust assembly (101) to the outside atmosphere which reducing the pressure and noise of the exhaust gases. The first catalytic converter (104A) is connected to a first catalytic adaptor (103A). Importantly, the first catalytic converter (104A) is disposed substantially in a downstream of the first catalytic adaptor (103A). The one end of the second catalytic converter (104B) is connected to the second exhaust pipe rear portion (102BR) and another end is operatively connected to the muffler unit (105). In another embodiment, the entire second catalytic converter (104B) is disposed and housed within the second exhaust pipe (102B).
[00042] The first catalytic converter adaptor (103A) having a first end portion (103AF) and a second end portion (103AS). The first end portion (103AF) being connected to one end of said first exhaust pipe (102A) and said second end portion (103AS) being connected to said catalytic converter assembly (104). In an embodiment, the second end portion (103AS) being connected to said first catalytic converter (104A). An outer diameter (D1) of said first end portion (103AF) of said first catalytic converter adaptor (103A) being different than an outer diameter (D2) of said second end portion (103AS) of said first catalytic converter adaptor (103A). In an embodiment, the outer diameter (D1) is lesser than outer diameter (D2). The second end portion (103AS) of said first catalytic converter adaptor (103A) extends laterally away from an imaginary central plane (A-A’) (as shown in figure 1) towards the ground to connect with said catalytic converter assembly (104), when viewed in a longitudinal direction (L-L’). The imaginary central plane (A-A’) being passing through the center of said vehicle (100). In an embodiment, the first catalytic adaptor (103A) is secured between the rear portion (102R) of the first exhaust pipe (102A), and the front-end portion of the first catalytic converter (104A). Further, the second catalytic adaptor (103B) is secured between the rear end portion of the first catalytic converter (104A) and front-end portion of the second exhaust pipe (102B). In another embodiment, the rear end portion of the first catalytic converter (104A) is attached to the front-end portion of the second exhaust pipe (102B). Further, the first catalytic converter (104A) is covered by a housing (202). The one end portion of the housing (202) is connected to the first catalytic converter adapter (103A) and another end is attached to the second catalytic converter adapter (103B).
[00043] In an embodiment, the first catalytic adaptor (103A) is configured to receive a flow separator member (201). The flow separator member (201) permits uniform exhaust gas flow around the first catalytic adaptor (103A) and the first catalytic converter (102A) without changing the design of the existing exhaust assembly. In another embodiment, the second catalytic adaptor (103B) is configured to receive a flow separator member (201). The flow separator member (201) permits uniform exhaust gas flow around the second catalytic adaptor (103B) and the second catalytic converter (102B) without changing the design of the existing exhaust assembly.
[00044] The exhaust gases from the second catalytic converter (104B) enters the muffler unit (105). The muffler unit (105) is designed to reduce the noise due to sound pressure created by the IC engine (107) on the exhaust gases by way of acoustic quieting. The emitted noise is ‘muffled’ by a series of resonating chambers (not shown) lined with insulation harmonically tuned to cause destructive interference, wherein opposite sound waves cancel each other out. The series of resonating chambers provides sufficient volume and time for diffusion of the exhaust gases resulting in better sound quality and decreased temperature. The exhaust gas is finally made to exit through a tail pipe (not shown) to the atmosphere. The muffler unit (105) is usually made of sheet metal using steel alloy as a material. Due to hot exhaust gas circulation throughout the various passages of the resonating chamber, the exterior surface of the muffler unit (105) can become very hot. Due to the disposition of the muffler unit (105) adjacent to the rear wheel and exposed outwards, there is a tendency for the muffler unit (105) to come in contact with a rider or passenger feet. Hence, a muffler guard (203) is attached on the outer surface of the muffler unit (105) to prevent burn injuries in event of contact of a rider or passenger feet with the muffler unit (105).
[00045] Figure 3 illustrates a top, a front, a perspective side, and a side view of the flow separator member (201). The flow separator member (201) for an exhaust assembly (101). In an embodiment, the flow separator member (201) enclosed in the first catalytic converter adapter (103A) to separates exhaust gases passage into two or more flow paths (as shown in the figure 2) to provide uniform heat distribution. The flow separator member (201) having an upstream end portion (201U) and a downstream end portion (201D). A cross section area of upstream end portion (201U) being smaller than said downstream end portion (201D). A curved portion (201A) being provided between said upstream end portion (201U) and said second end portion (201D). In an embodiment, the flow separator member (201) can be made up of metallic and nonmetallic material. In one embodiment, the flow separator member (201) is made up of steel.
[00046] Figure 4 illustrates the uniformity index graph illustrating the improved performance of the first catalytic converter (104A) according to the embodiment of the present subject matter. As observed in Fig. 2. when the flow separator member (201) is placed in a first catalytic converter adaptor (103A), the uniformity index is more (see A). However, if it is there is no flow separator member (201) placed to close, the performance of the first catalytic converter (104A) is not efficient as we face problems of non-uniform heating (see B). Hence, it is determined that when the flow separator member (201) is disposed in front of the first catalytic adaptor (103A), the performance of the first catalytic converter (104A) is largely improved and activation temperature is reached at a faster time, we get the best characteristics in terms of performance.
[00047] Furthermore, the exhaust assembly as per preferred embodiment is applicable for non-automotive application like generators etc. Further, it includes application multi-wheeled vehicles like three, or four wheeled vehicles as it will be apparent to those skilled in the art that changes in form, connection, and detail may be made therein without departing from the spirit and scope of the invention.
