Gas piston pulse engine

Abstract

The invention discloses a gas piston pulse engine comprising a spraying pipe (1). The spraying pipe (1) is internally provided with at least on combustion chamber (2); the inside and / or the side wall of the spraying pipe (1) are / is provided with at least one high-pressure fluid spraying nozzle (3) which takes the spraying direction of the spraying pipe (1) as the overall spraying direction and / orthe opposite spraying direction as the overall spraying direction; and the high-pressure fluid spraying nozzle (3) is communicated with a high-pressure fluid source (4) through a high-pressure fluid spraying controlling valve (5). The gas piston pulse engine has less motion parts and high compression ratio and solves the problems that the large numbers of motion parts of the prior combustion engine are difficult to lubricate and the pure ramjet engine can not be started in the static state and can not work in the low-speed working condition.

Description

technical field [0001] The invention relates to the field of engines, in particular to a gas piston pulse engine. technical background [0002] In the design of internal combustion engines, in order to make the mixture of fuel and air reach the high temperature and pressure required for the subsequent combustion and explosion, and to improve the thermal efficiency of the internal combustion engine, the intake air must be compressed. Three kinds of technical schemes are adopted in the existing internal combustion engine design to realize compressed air, that is, piston compressed air, turbine compressed air or ram compressed air. However, whether the air is compressed by mechanical components such as a piston (such as a piston internal combustion engine) or a compressor (such as a gas turbine, jet engine, etc.), or the air is compressed by using the high-speed motion of the internal combustion engine to compress the air (such as a ram engine), there are very obvious disadvan...

Problems solved by technology

However, whether the air is compressed by mechanical components such as a piston (such as a piston internal combustion engine) or a compressor (such as a gas turbine, jet engine, etc.), or the air is compressed by using the high-speed motion of the internal combustion engine to compress the air (such as a ram engine), there are very obvious disadvantages; the first two not only have complex structures and high manufacturing costs, but also need to lubricate the compressed air components such as pistons and turbines, which brings a series of problems, and the energy consumed by the compressed air itself comes from Because of the precious mechanical work that is hard to get, it reduces the thermal power conversion efficiency of the engine; although the latter solves the problems of the former two to a certain extent, it cannot work at low speeds and cannot be started under static conditions. ; In addition, whether it is turbo compressed air or ram compressed air, there is a problem of insufficient compression effect under low speed conditions

These have greatly restricted the improvement of the thermal efficiency of the existing internal combustion engine, the reduction of manufacturing costs and the expansion of the field of use
