Problems solved by technology

There are also double-groove and double-ring structures, such as Chinese patent documents 98228603.1 and 01239995.7, but they all use double-groove and double-ring for the piston gas ring, which cannot fundamentally solve the problem of air leakage and oil leakage due to poor sealing
[0013] The purpose of the present invention is to address the deficiencies in the prior art and provide a piston assembly especially suitable for use in aerodynamic engines. The piston assembly adopts three air ring grooves and two oil ring grooves, and each air ring groove Two air rings are used in the tank, so as to fundamentally solve the problem of air leakage and oil leakage due to poor sealing

Embodiment Construction

[0062] 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.

[0063] Before describing the specific embodiment of the present invention in detail, the energy of the compressed air engine will be theoretically analyzed.

[0064] 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 a device for engines, in particular to a piston component for aerodynamic engines. The piston component comprises a piston (51), three combined piston air rings and two piston oil rings (53), and the piston oil rings comprise a first piston oil ring and a second piston oil ring. The piston (51) is provided with a first air valve groove (504), a second air valve groove (505), a third air valve groove (506), a first oil valve groove (507) and a second oil valve groove (508). A first combined piston air ring is fitted in the first air valve groove (504), a second combined piston air ring is fitted in the second air valve groove (505), and a third combined piston air ring is fitted in the third air valve groove (506). The two piston oil rings are fitted in the first oil valve groove (507) and the second oil valve groove (508) respectively.

Description

technical field [0001] The present invention relates to a device for an engine, in particular to a piston assembly for an aerodynamic engine. 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 and researched and d...
