Self cooled engine

Abstract

Self-cooled engine including a cylinder, a cylinder head and a turbo-piston which freely reciprocates inside the cylinder. The cylinder head has a valve that achieves circumferential suction of air-fuel mixture into the cylinder. The valve mechanism is closed and opened by cylindrical cam by means of cam shaft. Circumferential suction of air-fuel mixture enables the cylinder to cool itself and to burn the fuel at the energy center effectively. The force of incoming stream of air-fuel mixture rotates the impeller on the piston which acts as a fan to cool the cylinder walls. The impeller blades deflect the flame from reaching the cylinder walls and acts as a thermal barrier between the energy center and cylinder walls. The high intensity compression swirl (HICS) created at the end of the compression stroke to ensure that the fuel combustion is efficient and instantaneous release of maximum energy.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

(28) The subject technology relates to the Sunflower mechanism or inlet valve mechanism and the turbo-piston assembly of an internal combustion (IC) engine, and in particular to methods of eliminating cooling losses, increasing the combustion efficiency and reducing harmful emissions. The advantages, and other features of the system disclosed herein, will become more readily apparent to those having ordinary skill in the art from the following detailed description of certain preferred embodiments taken in conjunction with the drawings which set forth representative embodiments of the present invention and wherein like reference numerals identify similar structural elements.

(29) All relative descriptions herein such as left, right, up, and down are with reference to the Figures, and not meant in a limiting sense. Additionally, for clarity common items have not been included in the Figures as would be appreciated by those of ordinary skill in the pertinent art. Unless otherwise specified, the illustrated embodiments can be understood as providing exemplary features of varying detail of certain embodiments, and therefore, unless otherwise specified, features, components, modules, elements, and/or aspects of the illustrations can be otherwise combined, interconnected, sequenced, separated, interchanged, positioned, and/or rearranged without materially departing from the disclosed systems or methods. Additionally, the shapes and sizes of components are also exemplary and unless otherwise specified, can be altered without materially affecting or limiting the disclosed technology.

(30) As will hereinafter be more fully described, the instant self-cooled engine provides an engine design that cools the cylinder walls and ensures complete combustion of fuel within the cylinder. This subject technology eliminates the need for a separate cooling system, thereby eliminating accessories like a coolant pump, thermostat and fan which consumes considerable engine power.

(31) Referring to FIG. 1, a sectional view of engine is shown and referred to generally by the reference numeral 100. The engine 100 includes a cylinder head assembly (1) which comprises a cylinder head body (8), a rocker arm (6), a Sunflower valve mechanism (3), an exhaust valve mechanism (2), a fuel injector, an igniter plug (25), an inlet manifold (29), an exhaust manifold (12), an engine cylinder (30) and turbo-piston assembly (4).

(32) The cylinder head body (8) is in the form two concentric cylindrical blocks where Outer cylindrical block is called suction chamber (27) and inner cylindrical block is called exhaust chamber (26). The inlet manifold (29) connected to the Suction chamber (27), which contains Sunflower valve mechanism (3). Sunflower valve mechanism (3) is concentrically disposed into the annular space of the cylinder head body (8). Exhaust chamber (26) contains the exhaust valve mechanism (2) and connected to exhaust manifold (12). An exhaust valve spring (7) seats on the stepped hole (9) of the cylinder head body (8). The rocker arm (6) is disposed on the top surface of cylinder head body (8), which keeps the exhaust valve (11) in a closed position by means of an exhaust valve spring (7).

(33) The exhaust manifold (12) and exhaust chamber (26) are in the form of an elbow (best seen in FIG. 7) which is integral part of the cylinder head body (8). Exhaust chamber (26) consists of exhaust valve (11) which is seated on exhaust valve seat (16) against the exhaust valve spring (7) force. Threaded holes on the cylinder head body (8) receive the igniter plug (25) to supply series of sparks and the fuel injector (31) to inject fuel into the suction chamber (27). The angle between inlet manifold (29) and exhaust manifold (12) axes between the range of 70-90. FIG. 2, FIG. 3 and FIG. 4 are different views of cylinder head assembly for better understanding and clarity.

(34) In the engine 100, circumferential suction is achieved by the Sunflower valve mechanism (Best seen in exploded view FIG. 8). The Sunflower valve mechanism (3) derives its name because the Sunflower valve mechanism (3) resembles the petals of the Sunflower. The Sunflower valve mechanism (3) is operated by cylindrical cam (38) to provide the angular movement to open and close the Sunflower valve mechanism (3). The exhaust valve (11) is operated by an Exhaust valve cam (34), which is conventional lobe cam and exhaust valve cam follower (33) (Best seen in FIG. 5 & FIG. 6). Both the exhaust valve cam (34) and cylindrical cam (38) are formed on the camshaft (13).

(35) Sunflower valve (18) is sandwiched between a Sunflower valve upper guide (17) and a Sunflower valve lower guide (19). The Sunflower valve upper and lower guides (17, 19) are fixed into the cylinder head body (8) by a Sunflower valve upper guide lock (35) and a Sunflower valve lower guide lock (49) to remain stationary. The Sunflower valve lower guide (19) has helical shaped radial channels (19a), which provides inlet passage for ingress of air-fuel mixture in a helical direction. The serrations (51) on the guide locks (35, 49) fit into the Sunflower valve guides (17, 19) which prevents the rotation of Sunflower valve guides (17, 19) when the Sunflower valve (18) is in motion (Best seen in FIG. 9). Sunflower valve (18) swing through the rectangular groove (47) to open and permit the air-fuel mixture flow into the cylinder. Sunflower valve assembly is closed at the bottom by Sunflower valve assembly cover (50).

(36) Sunflower valve mechanism is held between a Sunflower valve assembly stopper (42) and a Sunflower valve assembly circlip (45) (Best seen in enlarged view FIG. 7A). Sunflower valve assembly stopper is the annular protrusion outside of exhaust chamber to stop the upward movement of Sunflower valve mechanism (3) and is secured by Sunflower valve assembly circlip (45) to prevent axial movement downwards. The Sunflower valve lower guide (19) has larger height (h3) compared to height (h1) of Sunflower valve upper guide (17), to provide more gliding path for the incoming air and less heat transfer to the Sunflower valve mechanism (3). The less heat transfer to the Sunflower valve mechanism (3) ensures minimum thermal expansion and smoother action. The height (h1) of Sunflower valve upper guide (17) and height (h2) of Sunflower valve (18) are equal and smaller than the height (h3) of Sunflower valve lower guide (19). The upward thrust due to gas pressure ensures air tight sealing irrespective of wear and tear of the mating surfaces. It requires all the mating surfaces of Sunflower valve guides (17, 19) and Sunflower valve (18) are perfectly lapped so that minimum force is needed to actuate it.

(37) The Sunflower valve (18) used in this engine has 36 petals (Refer FIG. 10 for the Sunflower valve mechanism terminology). The Sunflower valve mechanism (3) has a petal angle () of 6 against the port angle () of 4 so that the Sunflower valve (18) can completely cover the radial channels with overlap angle of 1. The total angular movement of 5 is needed to open the Sunflower valve mechanism (3) by means of cylindrical cam (38) and the cylindrical cam follower (39). The angular play of the cylindrical cam (38) can be reduced by increasing the number of petals in Sunflower valve (18).

(38) Referring to FIG. 11, Sunflower valve (18) is in closed position by the Sunflower valve spring (37) force, which is seated on Sunflower valve spring seat (48). Referring to FIG. 12 Sunflower valve (18) is in open position against the Sunflower valve spring (37) force. FIG. 13 refers to cylindrical cam follower (39) positions with respect to camshaft axis (14). Cylindrical cam follower at closed position (39b) and cylindrical cam follower at open position (39d) are the extreme points of travel of the cylindrical cam follower (39). Follower mean position (39c) is the point when the camshaft axis and cylindrical cam follower axis (39a) coincides. As the cylindrical cam follower (39) moves in circular path, the follower axis (39a) shifts from camshaft axis (14) which is called follower offset. The follower offset should be minimum so that cylindrical cam (38) can exert maximum force on cylindrical cam follower (39). In order to reduce this offset, cylindrical cam follower swing angle (39e) should be equally divided from the follower mean position (39c).

(39) Igniter plug (25) generate series of sparks when starting the engine and it is not timed. The purpose of the Igniter plug (25) is to initiate combustion at starting similar to combustor used in gas turbines. For multi cylinder engines single igniter plug can be used. Injector injects the fuel into the suction chamber during suction stroke.

(40) FIG. 14 shows the exploded view of the Turbo-piston assembly (4) and crankshaft. Referring FIG. 15 the impeller (20) is mounted on the piston using impeller shaft (20a) which is integral part of impeller and secured by impeller circlip (54). It can be freely rotated by the force of incoming air-fuel mixture. As the impeller rotates at high speed, torsional forces will be acting on the piston (22) along with compressive load and therefore turbo-piston assembly (4) is subjected to torsionalcompressive load. In order to withstand this type of load conventional I section connecting rod is replaced with (pronounced as O-positive) connecting rod (23) (FIG. 16). The load acting on the impeller blades is safely transmitted to O positive connecting rod thus improves stability of engine at higher speeds.

(41) In the engine (100) air-fuel mixture is sucked into the cylinder circumferentially called as circumferential suction. The swirling stream of air-fuel mixture sweeps away the heat from the cylinder walls when it enters during suction stroke. During compression stroke, compressed swirling of air-fuel mixture burns fuel molecules at the energy center (21) effectively.

(42) The swirling stream of air-fuel mixture at the circumference of the cylinder is called circumferential swirl (56). Circumferential swirl (56) is responsible for cooling the cylinder walls as well as deflecting flame in such a way that it cannot touch the cylinder walls. The circumferential swirl (56) also rotates the impeller (20) which acts as a fan for cooling the cylinder walls. The impeller is mounted on the piston which is called as turbo-piston assembly. Turbo-piston assembly aggravates swirling action during compression stroke to generate High intensity compression swirl or HICS (57).

(43) The process of intensifying swirling to generate HICS is called as swirling exacerbation. In HICS the molecules move very closely with high velocity increases the chances of collision with each other. The circumferential swirl (56) prevent the flame propagation to the cylinder walls enhances the efficiency because less quantity of fuel is required to energize the energy center to perform the useful work on the piston.

(44) The central part of the impeller is called energy center (21). This is the inner space of the impeller where the swirling of the air-fuel mixture gets aggravated to cause HICS (57). In this space high velocity molecules involve in multiple collisions to release their maximum energy within short period. There are two types of energy centers depends on the direction of HICS (57), Direct swirl energy center and counter swirl energy center.

(45) In energy center the molecules moves in the orbit based on law of conservation of angular momentum depends on the molecular weight, the lighter molecules take smaller orbit, and heavier molecules take larger orbits. When the molecule enters the energy center, it breaks down into smaller molecules, take up the smaller orbits. The release of energy occurs until the molecule reaches smallest possible orbit or releases maximum energy.

(46) Sweep factor is the major criteria to achieve effective cooling of the cylinder. Sweep factor is the ratio of bore diameter to effective cylinder length (clearance length+stroke length).
Sweep factor=bore diameter/effective cylinder length (d/L) where L=c+1

(47) Swirling exacerbation is the process of intensifying swirling action of air-fuel mixture to cause HICS (57). Swirling exacerbation depends on sweep factor, circumferential swirl angle () and impeller swirl angle ().

(48) The energy center (21) of the cylinder of the present subject technology differs from the conventional combustion chamber in a way that it burns the fuel. During exhaust stroke always there is left over fire in the energy center. The left over fire possesses considerable energy for the subsequent cycles. The fuel is added just to supplement left over fire in order to maintain energy level of the energy center.

(49) FIG. 17 shows the suction stroke, where the incoming air-fuel mixture enters through the inlet manifold (29) hits the exhaust chamber (26) and cools it. Igniter plug (25) generates series of Sparks and fuel injected into the suction chamber (27). The air flow through the inlet manifold bifurcated along the suction chamber and drives the injected fuel and spark to the cylinder through the Sunflower valve (18) during suction stroke. The channels (19a) of the Sunflower valve lower guide (19) are curved helically and acts as nozzles, which causes the air fuel mixture to swirl circumferentially with high velocity. The swirling stream of air impinges on the impeller blades causing the impeller (20) to rotate. This is called circumferential swirl (56) and the fuel is thoroughly atomized to ensure effective combustion.

(50) FIG. 18 shows the compression stroke, where the Sunflower valve and exhaust valves are closed. The circumferential swirl gets aggravated to cause High intensity compression swirl or HICS (57) at the center of impeller. High intensity compression swirl (57) ensure every fuel molecule involve in multiple collisions to release maximum energy instantly.

(51) FIG. 19 shows the power stroke, where the hot gases of combustion force the piston downwards to convert heat energy into mechanical energy. The flame is generated in the form of disk of fire (58). The flame cannot reach the cylinder walls because of the following reasons. The bore diameter is greater than stroke length. Piston travel ceases very shortly and therefore not enough time for the flame to reach the cylinder walls. Impeller blades deflect the flame from not reaching cylinder walls The supplied fuel is just enough to be burned in the energy center.

(52) FIG. 20 shows the exhaust stroke, where the exhaust valve opens (59) and the products of combustion are expelled out of the cylinder (30). Certain amount of hot gases remains in the cylinder which possesses leftover energy. This leftover energy is useful for the subsequent cycles, so that less quantity of fuel can be supplied to maintain energy level of the energy center.

(53) FIG. 18 shows the Direct swirl energy center (DSEC), where the direction of HICS is same as that of circumferential swirl. This is the simple energy center where molecules involve in side-collision. This energy center can be employed in engines using high octane fuels.

(54) FIG. 19 shows the Counter swirl energy center (CSEC), where the direction of HICS (57) is opposite to that of circumferential swirl (56). The impeller blades have negative swirl angle in order to generate counter swirl. The impeller (20) should possess more kinetic energy in order to deflect the air stream in the opposite direction to cause HICS (57). Fuel molecules involve in head on collision when they enter into the energy center with high collision velocity. This enables strongly bonded atoms to rip off their molecules or even electrons to rip off from their atoms. This kind of energy center can be used to burn low octane fuels.

(55) FIG. 23 is an exploded view of another Sunflower valve mechanism without Sunflower valve guide locks and a Sunflower valve lock. As will be appreciated by those of ordinary skill in the pertinent art, the Sunflower valve mechanism of FIG. 23 utilizes similar principles to the Sunflower valve mechanism of FIGS. 1-22 described above. Accordingly, like reference numerals are used to indicate like elements. The primary difference of the Sunflower valve mechanism of FIG. 23 is the Sunflower valve upper guide lock (35), the Sunflower valve lock (36), and Sunflower valve lower guide lock (49) being integral with the respective toparts (17), (18), (19). As such, mating surfaces (61), (62) touch against surfaces (63), (64), respectively to prevent rotation of the locks (35), (49).

(56) It can therefore be seen that the present subject technology provides a self-cooled engine which is cooled by intake air-fuel mixture and provides more efficient combustion than existing engines. For these reasons, the instant subject technology is believed to represent a significant advancement in the art which has substantial commercial merit.

(57) The subject technology uses Gasoline fuel, however increasing compression ratio and sweep factor can allow for usage of diesel fuel. The subject technology includes a Sunflower valve lower guide which has plurality of helical shaped, radial channels which are concentric with the cylinder axis. The channels are closed or opened by Sunflower valve mechanism. Sunflower valve mechanism achieves high degree of homogenous air-fuel mixture by streamlining the air movement using turbo-piston. During suction stroke, the Sunflower valve mechanism causes circumferential flow of air-fuel mixture into the cylinder which cools the cylinder and causes the fuel to atomize effectively. The incoming air stream rotates the impeller on the piston, which acts as a fan to cool the cylinder walls. During combustion, the impeller blades also deflect the flame from reaching the cylinder walls, and act as a thermal barrier between the energy center and the cylinder walls.

(58) As can be seen, the engine of the present subject technology eliminates loss due to previously used cooling mechanisms, and significantly reduces incomplete combustion. In the engine of the present subject technology, fuel burns instantaneously at the center of the cylinder, and exerts force at the center of the piston. The cylinder is cooled by the fresh stream of incoming air, which eliminates the complicated cooling mechanisms currently used in internal combustion engines. High intensity compression swirl (HICS) created at the end of the compression stroke ensures that every molecule of the fuel involve in combustion. While there is shown and described herein certain specific structure embodying the subject technology, it will be manifest to those skilled in the art that various modifications and rearrangements of the parts may be made without departing from the spirit and scope of the underlying inventive concept and that the same is not limited to the particular forms herein shown and described except insofar as indicated by the scope of the appended claims.
