背景技术Background technique
发动机是一种把其他形式的能转化为机械能的装置，其中，热功发动机由于其投入小、损耗小而最为普遍。An engine is a device that converts other forms of energy into mechanical energy. Among them, thermal power engines are the most common due to their small investment and low loss.
热功发动机又分为容积式内燃机和冲击式发动机。容积式内燃机的原理是在压缩机的气缸内通入燃料，燃料混合压缩气体被点燃，***产生瞬间的高温高压气体膨胀做功，为往复运动的运作方式。分为4冲程和2冲程，即4个往复和2个往复做一次功。该种热能由于是大面积瞬间产生，冲击力大，在每次做功都会产生突然冲击的噪音和振动，很大程度的影响现场工人的正常工作；冲击式发动机是燃料在燃烧室中混合空气燃烧形成高温高压气体，并通过喷嘴冲击叶轮旋转做功。这两种热功发动机产生的高温高压气体在做功后的都被排出，都为开环单向做功的方式，这导致每一次做功的热功损耗都较大，也造成整个热能转化为机械能的过程中热效率都很低。Thermal power engines are further divided into volumetric internal combustion engines and impact engines. The principle of a positive displacement internal combustion engine is to inject fuel into the cylinder of the compressor, the fuel mixed with the compressed gas is ignited, and the explosion produces an instantaneous high-temperature and high-pressure gas expansion to do work, which is the operation mode of reciprocating motion. Divided into 4-stroke and 2-stroke, that is, 4 reciprocating and 2 reciprocating to do one work. Because this heat energy is generated instantaneously in a large area, the impact force is large, and sudden impact noise and vibration will be generated every time the work is performed, which greatly affects the normal work of the on-site workers. The impact engine is a combustion chamber where fuel is mixed with air High temperature and high pressure gas is formed, and the impeller rotates through the nozzle to do work. The high-temperature and high-pressure gas generated by these two heat power engines is discharged after the work is performed, and both are open-loop one-way work, which leads to a large thermal power loss for each work, and also causes the entire thermal energy to be converted into mechanical energy. The thermal efficiency of the process is very low.
