Spring piston and oxygen-enriched combustion engine

Abstract

According to the spring piston structure, an upper shell is sleeved on an upper bottle opening of a lower shell bottle, and a spring is fixed with the upper shell. The shells slide mutually, and the spring piston slides in the air cylinder. A piston ring is arranged outside the upper shell. A shell is prevented from being collided, a spring piston is prevented from being damaged, and a ring gasket which is made of non-metal materials and has telescopic capacity is arranged. When the spring piston is compressed to the last 0.5 mm, the two shells are in contact with the circular ring gaskets, and at the moment, the spring piston is very strong and is in soft contact. And the telescopic length of the spring piston is determined within 5mm. The telescopic length is very short to meet the engine rhythm. And the device can be continuously used and self-repaired when being far away from the elastic range. And the piston can be used as a conventional piston after losing elasticity. And continuous and long-term use can be realized through accurate manufacturing and timely heat dissipation. The spring piston has the functions that compression can be achieved, and most of energy generated during compression can be recycled to be released in the work stroke. The oxygen-enriched combustion uses strong power of a spring piston to increase the air inlet space and improve the compression ratio of an air cylinder. The piston machine is suitable.

Description

[0001] The invention discloses a spring piston and an oxygen-rich combustion engine, which relate to the field of piston-type gasoline and diesel engines.

[0002] The basic technology of the spring piston and oxygen-rich combustion engine is the piston four-stroke engine.

[0003] The spring piston replaces the conventional piston. The structural characteristics of the spring piston are: the upper shell like a bottle cap is sleeved on the lower shell like the upper part of the bottle mouth, and only the two ends of a spring are fixed to the two shells. External force can make the two shells slide against each other, and external force can make the entire spring piston slide in the cylinder. The outer side of the upper shell is equipped with a piston ring. In order to prevent the two shells from colliding and the spring piston from being damaged, a circular ring gasket with a little telescopic ability made of non-metallic materials that are resistant to pressure, heat and engine oil is placed inside and outside. When the spring piston is compressed to the last 0.5 mm or so, the two shells contact the circular ring gasket. At this time, the spring piston is still very strong and is a soft contact. When designing the spring piston, first determine the "telescopic length" of the spring piston within the range of 1 to 5 mm. Calculate the strength and length of the spring according to the selected "telescopic length" of the spring piston and the cylinder compression ratio required by the engine. If the "telescopic length" of the spring piston is very short, the telescopic frequency can be very high, which can keep up with the rhythm of the engine. The "telescopic length" is very short, and the spring compression ratio, that is, the ratio of the spring length of the spring piston to the "telescopic length" of the spring piston (the only compression ratio different from the cylinder compression ratio), is very large, so it can be far away from the upper limit of the elastic range of the spring, and the spring piston can be used continuously. The short "telescopic length" is conducive to the self-repair of the spring piston. The engine using the spring piston will never stop because of the use of the spring piston. Even if the spring of the spring piston completely loses its elasticity, it can still be used as a regular piston (this situation will not happen). There is no need to add lubricating oil. If this kind of spring piston can be accurately manufactured and can dissipate heat in time when used, it can be used continuously and for a long time.

[0004] The functional characteristics of the spring piston are: the spring piston can be compressed normally, and can temporarily store most of the energy of the reaction force generated during compression in the compressed spring, and release it all at once during the power stroke. The strong spring piston is compressed only at the end of the compression stroke. As long as the spring piston under pressure is fully extended toward the crankshaft at the end of the power stroke, the greater the pressure, the greater the power that can be released, regardless of the "extension length". In fact, this is a considerable amount of energy recovered.

[0005] Oxygen-enriched combustion is to use the strong power generated by the spring piston to increase the intake space and improve the cylinder compression ratio. The increase in oxygen can minimize the probability of incomplete combustion. The gasoline engine takes in a mixture of fuel and air, so it is necessary to appropriately change the proportion of the mixture to achieve complete combustion to improve the thermal efficiency of the fuel. If the cylinder compression ratio can be increased, it is recommended that the gasoline engine should not ignite 5 degrees in advance to the "top dead center" and ignite. The diesel engine can also delay the injection of fuel by 5 degrees accordingly, so that the thrust generated will be greater.

[0006] The spring piston and oxygen-enriched combustion technology are suitable for use on all engines with pistons. Regardless of the size of the engine and the number of cylinders, all are within the scope of the claims of this application.

[0007] The inventor has provided a design of a spring piston, and any design of the spring piston is within the scope of the claims of this application.

[0008] Timely heat dissipation and not exceeding the temperature limited by the spring are the key to this technology.

[0009] As long as there is oil, there will be fuel engines, and reducing emissions and saving energy are the most important things.

[0010] The specific situation of the spring piston and the oxygen-rich combustion engine will be explained below in conjunction with the accompanying drawings (oxygen-rich combustion does not require drawings and illustrations). BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 This is a diagram of the "top dead center" position of the spring piston at the end of the compression stroke of this technology; Figure 2 These are the "bottom dead center" position diagrams of the spring piston at the end of the power stroke of this technology. They are all axial cross-sectional diagrams and principle schematic diagrams.

[0012] like Figure 1 As shown, Figure 1 It is mainly composed of a heat-insulating fixing plate 0 of a spring piston, an upper outer shell 1, a lower outer shell 2, a spring 3 (black thick twisted wire), a middle hollow fixing column 4, a base 5, an inner ring gasket 6, an outer ring gasket 7, a piston ring 8, a connecting rod 9, a crankshaft 10, a base vent 11, a hollow fixing column vent 12 and a cylinder body 13, an intake or exhaust passage 14, an ignition or injection passage 15, an exhaust or intake passage 16, a combustion chamber with compressed gas 17, etc.

[0013] like Figure 2 As shown, Figure 2It is mainly composed of a heat-insulating fixed plate 0 of a spring piston, an upper shell 1, a lower shell 2, a spring 3, a middle hollow fixed column 4, a base 5, an inner ring gasket 6, an outer ring gasket 7, a piston ring 8, a connecting rod 9, a crankshaft 10, a base vent 11, a hollow fixed column vent 12 and a cylinder body 13, an intake or exhaust passage 14, an ignition or injection passage 15, an exhaust or intake passage 16, an exhaust chamber 18, and a "telescopic length" 19 of the spring piston.

[0014] Among them, (1) the heat-insulating fixing plate 0 can both insulate and firmly fix the upper end of the spring, and it is mainly made of heat-insulating materials, etc.; (2) the use of a black thick twisted line to represent a spring of the spring piston can prove that the spring wire diameter is large, which can show that the spring is very strong. The spring with a large wire diameter can withstand relatively higher temperatures, and it can be very durable if it stretches a few millimeters; (3) there are several vents 11 on the base, which are all conducive to heat dissipation by wind; (4) the inner side of the lower shell around the spring is also lined with heat-insulating materials. In short, the spring of the spring piston is insulated by heat-insulating materials around it, and there are vents for wind heat dissipation. The spring is still relatively "cool" in such an environment. If this type of engine is used in a car, there is wind when the car is running, and wind heat dissipation is acceptable. Load-carrying vehicles can also use water cooling for heat dissipation. However, it is better to use an electric fan to dissipate the residual heat of the engine within a few minutes after parking, which can greatly extend the service life of the engine; if this type of engine is relatively fixed when used, both wind heat dissipation and water heat dissipation are acceptable.

[0015] The principle of the spring piston will be explained below in conjunction with the accompanying drawings.

[0016] like Figure 1 As shown, Figure 1 This is the "top dead center" position diagram of the spring piston at the end of the compression stroke of this technology. At this time, the spring of the spring piston has been compressed and contracted, and energy is temporarily stored at the same time, and the gas in the cylinder is compressed. Figure 2 As shown, Figure 2 This is the "bottom dead center" position diagram of the spring piston at the end of the power stroke of this technology. At this time, the "extension length" 19 of the spring piston is displayed, that is, the spring of the compressed spring piston is fully extended, and the energy temporarily stored in the compression stroke is released together with the power, which recovers a considerable amount of energy. Figure 2 The "extension length" 19 of the spring piston shown in the figure is only 5 mm, and the exhaust chamber 18 also appears. It can also be seen that the "extension length" of the spring piston is much shorter than the compression distance of the spring piston, that is, the spring piston can only be compressed and retracted at the end of the compression stroke. Figure 1 Figure 2There is still a difference. In fact, if the "telescopic length" of the spring piston is determined to be 3 mm, it is also possible. It is better to determine that the "telescopic length" of the spring piston is short rather than long. A short "telescopic length" of the spring piston is very advantageous for the continuous and long-term use of the spring piston.

[0017] There are two compression ratios mentioned above: one is the cylinder compression ratio that is already in the basic technology, and the other is the spring compression ratio. The two compression ratios correspond to two sliding parts, so please note the difference.

[0018] In order to prevent the spring piston from attenuating, the following methods are adopted based on the above contents: (1) Determine the "telescopic length" of the spring piston and use a spring with strong elastic force to match the short "telescopic length". In addition, the short "telescopic length" of the spring is easy to self-repair, which is an effective way to prevent spring attenuation. (2) Dissipate heat in time. When the car engine is running, the wind can be used to dissipate heat. After the car stops for a few minutes, use an electric fan to dissipate the residual heat. This is very important and must be implemented. This is also an effective way to prevent spring attenuation. (3) The structure of the spring piston also adopts a base with several vents, a hollow fixed column in the middle, and insulation materials. (4) There is still a precedent for using springs on engines, and the intake and exhaust valves are also controlled by springs. Under such conditions, the attenuation of the spring is greatly slowed down. In addition, the spring has the ability to self-repair at a shorter "telescopic length", so the spring piston can be used continuously and for a long time.

[0019] The technical aspects not mentioned above are all based on basic technologies.
