Description

Air engine assembly with throttling control technology

The present invention relates to the field of aerodynamic vehicles, and more particularly to an air engine assembly having a throttle control function. Background technique

With the continuous development of science and technology and the continuous improvement of living standards, human demand for energy has reached an unprecedented peak after entering the second half of the twentieth century. Various traditional energy sources on the earth have been exhausted in a short period of time. Resource reserves are drying up. With this excessive exploitation of energy, humans inevitably encounter two global problems, one is the environmental pollution problem accompanied by industrial development, and the other is the energy shortage caused by the exhaustion of resources.

The continuous strengthening of the greenhouse effect and the deepening of the energy crisis have made it necessary for mankind to begin to face these two major problems and to start researching countermeasures and measures to alleviate and solve these problems. The development and utilization of renewable energy sources can not only reduce the consumption of traditional energy reserves on the basis of guaranteeing human energy demand, but also reduce the emissions of waste gas and waste generated by burning fossil energy, and alleviate the environment from the root cause. pollution problem. As a prominent representative of new energy sources, solar energy, wind energy, and hydropower have been used in many fields and successfully replaced fossil energy. However, in some areas, traditional energy sources are still used to provide power, and research on new energy sources is less used.

However, most of the current cars still use traditional fossil energy engines, which results in The consumption of fossil energy is large, and cars using traditional fossil energy engines emit a large amount of toxic gases during driving, and the pollution to the environment is quite serious.

There are already some aerodynamic vehicles that use air energy as power in the prior art. These vehicles use a different aerodynamic engine than a fossil energy engine, relying on the energy provided by high pressure air to drive the engine and the car. This emerging aero-powered vehicle does not rely on burning traditional fossil energy to obtain power. It uses only compressed air. It achieves zero emissions to the outside world during driving, and it is pollution-free and in line with development trends. However, aerodynamic vehicles rely on high-pressure gas on their bodies. The tank is used to carry compressed air, which is limited by the size of the body. The high-pressure gas tank cannot be set very large, so the gas storage is small, and the existing aerodynamic engine does not have a throttle control mechanism, and it is difficult to achieve accurate release of compressed air.

The liquid air in the liquid storage tank 1 is obtained by the high pressure and low temperature treatment of the compressed air, and the density thereof is increased and the volume is reduced. Under the same volume, the compressed air can store more liquid air than the general compressed air. However, the liquid storage tank 1 has a high manufacturing process, is capable of withstanding sufficient pressure and has a heat insulating function to maintain the low temperature inside the tank, and in order to achieve this, it can be manufactured using existing high-strength materials and An external thermal insulation layer is added.

The air engine assembly having the throttling control function is applicable to both the piston engine of the prior art and the turbo engine. When applied to a piston engine, the rainbow body 40 refers to a gas cylinder that houses a piston, and when applied to a turbine engine, the rainbow body 40 refers to a turbine chamber in which a turbine is installed. The number of the cylinders 40 in the air-engine assembly having the throttle control function is not limited, and may be configured according to actual use requirements. The number of the throttle control mechanisms 42 varies depending on the applicable object and the cylinder 40 Choose from different quantities. For a multi-pneumatic piston engine in which the intake and exhaust strokes are staggered, at least two of the throttle control mechanisms 42 are required to supply air to the respective strokes of the different strokes; and for the turbine engines in which the intake and exhaust strokes are synchronized, only A throttle control mechanism 42 is provided to cause the throttle control mechanism 42 to simultaneously supply air to a plurality of turbine chambers. Of course, for both types of engines, a throttle control mechanism 42 of the same number as the cylinders 40 may be provided to supply a plurality of said narratives 40, respectively.

Before the vehicle is started, the liquid storage tank 1 and the high pressure gas tank 2 are filled with sufficient liquid air and compressed air. When the vehicle is started, the compressed air outputted from the high pressure gas tank 2 allows the throttle to be throttled. The engine assembly of the control function is activated to drive the vehicle. If the air pressure of the compressed air outputted in the high pressure gas tank 2 is sufficient, the pressure valve 3 is closed, and the liquid storage tank 1 is not externally outputted, when the high pressure gas tank 2 is When the compressed air pressure is insufficient, the pressure valve 3 is opened, the liquid air in the liquid storage tank 1 flows out and is vaporized into compressed air, and then heated and pressurized by the heating device 6 to enter the high-pressure gas tank. 2.

Compared with the prior art, since the present invention provides the liquid storage tank 1 and the high pressure gas tank 2 on the aerodynamic vehicle, liquid air obtained by using low temperature and high pressure conditions is stored in the liquid storage tank 1. During the running of the aerodynamic vehicle, liquid air is discharged from the liquid storage tank 1 and vaporized into compressed air due to pressure reduction, and compressed air enters the high-pressure gas tank 2 for temporary storage and toward the air. The engine supplies air. Since the liquid air occupies a much smaller volume than the compressed air, the liquid air carried in the liquid storage tank 1 can meet the demand of the aerodynamic vehicle for long-distance driving, and the aerodynamic vehicle inflation is greatly reduced. The number of times has improved its practicality. The pressure valve 3 including the valve body 30, the piston 31 and the spring 32 is disposed between the liquid storage tank 1 and the high pressure gas tank 2, thereby realizing only the compressed air outputted from the high pressure gas tank 2 When the air pressure is insufficient, the pressure valve 3 is opened and the liquid storage tank 1 delivers compressed air to the compressed air, thereby achieving the purpose of saving compressed air. Since the throttle control mechanism 42 is disposed in the air motor assembly, the first sliding member 425a is slid in the first accommodating cavity 421a by the cam 423 to isolate or communicate the first The air inlet 421b and the first air outlet 421c realize the opening and closing of the air inlet 40a of the rainbow body 40 by a simple structure, and the cam 423 is drivingly connected with the main shaft 41 to achieve the air inlet. The purpose of synchronizing the opening and closing of 40a with the working state of the rehearsal 40 ensures that the intake air is accurate and timely, and avoids supplying air to the rainbow body 40 during exhausting, thereby eliminating energy waste. At the same time, the linear driving mechanism 424 is used to drive the second sliding member 425b to slide in the second accommodating cavity 422a to change the communication area between the second air inlet 422b and the second air outlet 422c. The precise adjustment of the intake air amount of the cylinder block 40 achieves the purpose of adjusting the output speed of the air engine assembly.

The above disclosure is only a preferred embodiment of the present invention, and its function is to facilitate understanding and implementation by those skilled in the art, and of course, the scope of the present invention is not limited thereto, and thus the scope of the present invention is made. Equivalent variations are still within the scope of the invention.
