TECHNICAL FIELD

The present invention in general relates to a field of mechanical engineering. More particularly, the invention relates to an improved vehicle wheel rotation apparatus.

BACKGROUND

Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.

In most of the existing engines, there are lots of components that work together and/or independently. Due to large number of components, total input energy is not converted into work as some of the components require comparatively more input energy. Hence, there is always some energy loss while running/using the engine, sometimes even for running the engine itself. For example, some energy is lost in movement of a piston within the bore. In other words, efficiency of the engine is not attainable to the fullest, compared to the input energy. Furthermore, there persists a very common problem of frequent maintenance and its cost as well. Usually, when there are lots of moving components, the maintenance cost is high.

In case of vehicles, hot gases are exhausted and are thrown to the environment. Such gases are wasted as these hot gases also carry along the energy which they possess from fuel combustion. There is, therefore, a need in the art to provide an apparatus/system which can provide much increased efficiency and thus a solution to the above mentioned problems. SUMMARY

Before the present apparatuses, methods and systems along with components related thereto are described, it is to be understood that this disclosure is not limited to the particular methods, apparatuses, systems and their arrangement as described, as there can be multiple possible embodiments which are not expressly illustrated in the present disclosure but may still be practicable within the scope of the invention. It is also to be understood that the terminology used in the description is for the purpose of describing the particular versions or embodiments only, and is not intended to limit the scope of the present application. This summary is not intended to identify essential features of the subject matter nor it is intended for use in detecting or limiting the scope of the subject matter.

In one embodiment, an improved vehicle wheel rotation apparatus is described. The apparatus may comprise a combustion chamber and one or more turbines. The combustion chamber may comprise one or more inlet for fuel and air, and an outlet port. Each turbine may comprise casing/housing, a runner, an inlet port and an outlet port. Plurality of bars may be attached to the runner of each turbine. The runner may be mounted on one end of a shaft and other end of the shaft may be coupled to an axle of the vehicle.

A non-return valve may be placed at entry of the two tubes. A jet of exhaust gases from the combustion chamber may pass in the attachment via the non-return valve. The jet of exhaust gases that exits the attachment through last tube, with reducing cross-section near opening, may further enable increment in velocity of exhaust gas, resulting in thrust to the bar to which the attachment is already fitted, thus providing additional rotations to the runner and eventually to the one or more wheels of the vehicle.

In another embodiment, an improved vehicle wheel rotation apparatus is described. The apparatus may comprise a combustion chamber and one or more turbines. The combustion chamber may comprise one or more inlet for fuel and air, and an outlet port. Each turbine may comprise casing/housing, a runner, an inlet port and an outlet port.

201 and one or more turbines (202,211). In one embodiment, an outlet 213 of the first turbine

202 may be connected to inlet of the second turbine 211. (Hereinafter “first turbine 202” may be referred as “turbine 202” and may be used interchangeably).

The combustion chamber 201 may comprise one or more inlet for fuel and air (209,212), and an outlet port 207. The air may enter the combustion chamber via the inlet port 209, wherein the air is supplied by a fan 210. The fan 210 may rotate in one direction and further enable compression of a fuel and air mixture. The combustion chamber 201 may be utilized for combustion/burning of fuel along with air, thus forming the exhaust gases. The outlet port 207 of the combustion chamber 201 may comprise a narrow opening that may further enable the exhaust gases to come out with high force and/or high velocity. In other words, the exit of the high velocity exhaust gases from the outlet port 207 of the combustion chamber 201 may also form a jet/stream of exhaust gases. In one embodiment, the runner of the second turbine 211 may be coupled to the fan/blower 209 via a shaft.

Each turbine (202,211) may comprise a casing/housing 202a, a runner 203, an inlet port 208, an outlet port 213, plurality of rods/bars 204 and plurality of tubes 205.

Figure 3 illustrates an improved vehicle wheel rotation apparatus 300, in accordance to another embodiment of the present disclosure. The apparatus 300 may comprise a combustion chamber 301 and one or more turbines (302,311). In one embodiment, an outlet port 313 of the first turbine 302 may be connected to an inlet port of the second turbine 311.

The combustion chamber 301 may comprise one or more inlet for fuel and air (312,309), and an outlet port 307. The air may enter the combustion chamber 301 via the inlet port 309, wherein the air is supplied by a fan 310. The fan 310 may rotate in one direction and further enable compression of a fuel and air mixture. The combustion chamber 301 may be utilized for combustion/burning of fuel along with air, thus forming the exhaust gases. The outlet port 307 of the combustion chamber 301 may comprise a narrow opening that may further enable the exhaust gases to come out with high force and/or high velocity. In other words, the exit of the high velocity exhaust gases from the outlet port 307 of the combustion chamber 301 may also form a jet/stream of exhaust gases. In one embodiment, the runner of the second turbine 311 may be coupled to the fan/blower 309 via a shaft.

Each turbine (302,311) may comprise a casing/housing 302a, a runner 303, an inlet port 308, an outlet port 313, plurality of rods/bars 304 and plurality of tubes 305. The plurality of bars 304 may be attached to the runner 303 of each turbine. The runner 303 of the turbine 302 may be mounted on a shaft at one end and other end of the shaft may be coupled to the shaft/axle of the vehicle in order to provide rotation to the one or more wheels of the vehicle. The plurality of rods/bars 304 may be connected/linked to the runner 303. In one embodiment, the inlet port 308 of the turbine 302 may be connected to the outlet port 307 of the combustion chamber 301. The apparatus 300 may be characterized by an auxiliary attachment 305 that may be retrofitted at surface of each bar 304 present in each turbine. The auxiliary attachment 305 may comprise 3- tube arrangement, such that the one end of all tubes (305a, 305b, 305c) form an arc-shape for the auxiliary attachment 305. In one embodiment, the arc-shape of the auxiliary attachment 305 may coincide with the inner wall of the casing 302a. A predefined gap may be maintained between the auxiliary attachment 305 and the inner wall of the casing 302a, in order to enable entry and exit of gases from the auxiliary attachment 305.

Two tubes (305a, 305b) of the auxiliary attachment 305 may enable entry of jet of exhaust gases into the attachment 305 and further facilitating the plurality of bars 304 for initiating rotation of the runner 303. The two tubes (305a, 305b) of the auxiliary attachment 305 may be positioned at a predefined height such that one of the two tubes (305a, 305b) of the attachment 305 is coaxial to the inlet port 308 of the turbine 302. At least one non-return valve 306 may be placed (306a, 306b) are placed at entry of the two tubes (305a, 305b). The jet of exhaust gases from the combustion chamber 301 may pass/enter in the attachment 305 via the at least one non-return valve (306a, 306b). The jet of exhaust gases that exits the attachment 305 through last tube 305c, with reducing cross-section near opening, may further enable increment in velocity of exhaust gas, resulting in thrust to the bar 304 to which the attachment 305 is already fitted, thus providing additional rotations to the runner 303 and eventually to the one or more wheels of the vehicle. The thrust to the bar 304 may initiate after the bar 304 rotates by 90 degrees from the initial position at which the exhaust gases start entering the auxiliary attachment 305. The additional rotation of the runner 303 may be increased by 15-30%.

In one embodiment, diameter of all the tubes (305a, 305b, 305c) of the auxiliary attachment 305 may be equal to or larger than diameter of the inlet port 308 of the turbine. The diameter of all the tubes (305a, 305b, 305c) may be same. In another embodiment, the diameter of all the tubes (305a, 305b, 305c) may be different than each other.

In one embodiment, the tubes (305a, 305b, 305c) may further comprise one or more bends in order to provide direction to the exhaust gases, entering from the two tubes, towards the last tube for exiting from the auxiliary attachment 305. In another embodiment, shape of the tubes of the auxiliary attachment 305 may be selected from round, elliptical and square.

In one embodiment, the tube 305c may comprise a nozzle near one end of the tube from where the exhaust gases exit from the attachment 305. The thrust on the bar 304 may be created via the jet/stream of exhaust gases and the auxiliary attachment 305.

In one embodiment, the jet/stream of exhaust gases may be created either by a jet engine or the combustion chamber 301. The outlet port of the combustion chamber and the inlet port of the turbine may comprise either a nozzle and/or a narrow opening in order to pass the exhaust gases.

In another embodiment, the apparatus may be implemented for an airplane using jet engines. The apparatus 300 may be placed near the exhaust of the air plane, wherein hot gases come out from the airplane engine. In one embodiment, the combustion chamber may be replaced/removed. The exhaust gases may further enter the turbine 302. The shaft of the turbine 302, on which the runner 303 is installed, may be coupled to the second turbine 311. The second turbine 311 may work in opposite manner/direction as compared to a normal turbine. The plurality of rod/bars of the second turbine 311 may be fixed in such a way that the second turbine 311 will push the air to atmosphere in the opposite direction to movement of the air plane and the jet engine. The apparatus 300 may provide support to the jet engine for pushing back which will provide more reaction force in order to move the airplane in forward direction.

In an exemplary embodiment, the turbines (302, 311) may comprise respective shafts that are connected through gears in order to increase the speed of runner of the turbine 311. Therefore, the speed of the runner of the turbine 311 may be higher than that of runner 303 of the turbine 302. In an exemplary embodiment, the apparatus (200,300) may be utilized as a primary or as secondary/additional apparatus that enables movement of the vehicle. The movement of the vehicle may be in forward or reverse direction by storage of energy/power within the apparatus, similar to use of flywheel in the four stroke engine that drives the vehicle. Furthermore, the jet/stream of the exhaust gases generated can also be utilized for different purposes. In an exemplary embodiment, power from turbine may be extracted through output shaft in the apparatus (200,300). The shaft may drive an aircraft propeller or ground vehicle (not shown) after an appropriate step-down in a gearbox.

In yet another embodiment, the apparatus (100,200,300) may be utilized for reducing the existing speed of the vehicle by implementing the apparatus (100,200,300) such that the jet/stream of the exhaust gases tends to oppose the rotation of the axle of the vehicle.

In an exemplary embodiment, the apparatus (100,200,300) may reduce the exhaust losses by implementing nozzles and valves, attached to the periphery of the casing.

Overall, the hot burned/exhaust gases leave combustion chamber, pass through first turbine and then through the bars of turbine. First turbine may further pass through second turbine. The second turbine may provide power to the fan/blower via a shaft. The fan/blower may provide fresh air to the combustion chamber.

In accordance with embodiments of the present disclosure, the vehicle wheel rotation apparatus, described above may have following advantages including but not limited to:

• Provides comparatively higher mileage than existing engine.

• Low maintenance cost and easy to replace, due to less number of parts.

• No complex arrangement required to run the vehicle.

• Can be retrofitted on the existing engines.

• Can work as an alternative to existing engines.
