Problems solved by technology

Obviously, this four-stroke compressed air engine disclosed in patent document CN101413403A greatly wastes effective power strokes, which limits the efficiency of the engine.
And the exhaust gas of this kind of engine cannot be recycled well, and it needs a large enough air storage tank to store high-pressure air to work for a long enough time, which reduces the application prospects of compressed air engines in industry

Embodiment Construction

[0055] The following description is merely exemplary in nature and not intended to limit the disclosure, application or use. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

[0056] Before describing the specific embodiment of the present invention in detail, the energy of the compressed air engine will be theoretically analyzed.

[0057] The working process of the compressed air engine is relatively simple, only the process of expanding the compressed air to do work. Such as Figure 12A as shown, Figure 1-5 It is the isothermal expansion process of compressed air, and 1-6 is the adiabatic expansion process of compressed air. The work done by compressed air in the engine cannot be a complete isothermal process, usually between the isothermal process and the adiabatic process. In order to improve the energy utilization rate of compressed air, a multi-stage adiabatic process can be used...

Abstract

The invention relates to an engine, in particular to a compressed air power engine assembly with compressed air serving as supplementary return circuit. The compressed air power engine assembly with compressed air supplementary return circuit comprises an engine body (1), a multi-cylinder power distributor (2), a power device (4), a controller system (6), an air inlet control speed regulation valve (23), a high-pressure air tank group (13), a constant-pressure tank (16), an electronic control unit (ECU) (29) and a compressed air supplement return circuit. The compressed air supplementary return circuit comprises an air compressor (7), a condenser (11), a pressure limit valve (702), a sequence valve (705), a tail gas recovery tank (9), an electric turbine one-way air pump (19) and a tail gas silencer (22).

Description

technical field [0001] The invention relates to an engine, in particular to an aerodynamic engine assembly using compressed air as a supplementary power source. Background technique [0002] Engines are widely used in all walks of life. In modern transportation tools such as automobiles and ships, piston-type internal combustion engines that use fuel as a power source are generally used. On the one hand, this kind of engine using fuel oil as the power source pollutes the environment due to insufficient fuel combustion, so that the discharged gas contains a large amount of harmful substances and pollutes the environment. The shortage makes the development and utilization of fuel engines more and more restricted. Therefore, developing new, clean, non-polluting alternative energy sources, or reducing fuel consumption and emissions as much as possible has become an urgent problem in engine development. To this end, countries have gone through complex and arduous explorations a...
