The following specification particularly describes the invention and the manner in which it is to be performed.
AN EXHAUST GAS DISCHARGE SYSTEM AND METHOD THEREOF
FIELD OF THE DISCLOSURE
[0001] This invention generally relates to a field of vehicle exhaust systems, and in particular, to an exhaust gas discharge system and method thereof.
BACKGROUND
[0002] The subject matter discussed in the background section should not be assumed to be prior art merely as a result of its mention in the background section. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also correspond to implementations of the claimed technology.
[0003] There is an increasing demand for more efficient, compact, and space-saving solutions across all vehicle subsystems. The exhaust gas system plays a major role in controlling emissions, managing engine heat, and contributing to overall vehicle performance. Further, the exhaust system comprises exhaust manifolds, pipes, catalytic converters, mufflers, and heat recovery components. In heavy-duty vehicles, such as those used in mining and construction, the exhaust system must also withstand high temperatures, vibration, and mechanical stress due to continuous operation in rugged environments.
[0004] However, conventional exhaust systems are often bulky, heavy, and occupy larger spaces that may cause limitations in modern vehicles that prioritize structural efficiency and functional compactness. In specialized applications such as mining and construction, especially in vehicles with tipper bodies, the challenge intensifies due to harsh operating environments and material handling issues. In such cases, an exhaust heated tipper body system is employed, where the heat from the exhaust gases of the vehicles is utilized to warm the floor of the tipper body. This heating prevents the adhesion of sticky materials such as lignite or wet soil, facilitating smoother unloading and improved material flow. However, routing exhaust pipes in such configurations introduces additional complications. One major issue observed in field operations is heavy dust cloud formation during vehicle movement on unpaved or dirt roads. Thus, there is a need for an improved exhaust system that not only facilitates body heating and structural stability during articulation but also minimizes dust generation, reduces weight of the system.
[0005] According to the patent application "KR200471220Y1" titled "A loading floor heating apparatus using the engine exhaust gas for a cargo truck," invention relates to a truck loading box floor heating apparatus using exhaust heat of an engine, and more particularly, to unload the loaded cargo by preventing the freezing of the loaded cargo by evenly heating the bottom of the truck loading box using the engine exhaust heat of the truck. It is related with the bottom of the loading box floor heating device using the exhaust heat of the engine to facilitate the configuration, the configuration of the inside of the loading compartment of the truck is divided up and down, a certain space is formed in the lower side, the front side and the rear side of the bottom surface of the loading box An exhaust gas circulation space part having an inlet through which the exhaust gas of the engine flows in and an outlet through which the inflow exhaust gas is discharged; An induction pipe installed between the engine and the lower end of the loading box so that the exhaust gas discharged from the engine is guided to the inlet; An exhaust pipe branched from the induction pipe and installed to discharge exhaust gas to the outside; First and second valves and which are inserted into respective pipes of the induction pipe and the exhaust pipe to control the exhaust gas to be discharged to any one of the induction pipe or the exhaust pipe and a control unit installed around the driver's seat and the vehicle body to selectively control the first and second valves.
[0006] Another patent application, " US7320504B2," titled "Vehicle heater using engine exhaust," describes a heater for a vehicle having an engine that generates hot exhaust gases includes a distribution pipe extending along a cargo carrying part of the vehicle. The distribution pipe is operatively connected to an engine exhaust pipe such that engine exhaust can flow through the distribution pipe when the engine is running. The distribution pipe has a plurality of openings therein through which exhaust is discharged to heat the cargo carrying part of the vehicle when the engine is running. Each opening has a cross-sectional area substantially smaller than a cross-sectional area of the distribution pipe.
[0007] In any of the discussed prior arts, describe complex routing of exhaust gases via a series of pipes and fixed circulation chambers are not adaptable for dynamic movement and vibrations experienced in the tipper body during the time of articulation. Further, the direct exhaust gases towards the ground causes the formation of dust clouds, reducing visibility and posing safety risks. Therefore, there remains a need for an exhaust gas heating system with flexible joints, support brackets and managed exhaust routing to reduce dust formation, pressure loss, while being more cost- effective and compact vehicle designs.
