Description

Engine

Technical Field

The invention relates to the technical field of engines, in particular to an engine.

Background

An engine is a machine capable of converting other forms of energy into mechanical energy, including, for example, internal combustion engines (reciprocating piston engines), external combustion engines (stirling engines, steam engines, etc.), jet engines, electric motors, and the like. Such as internal combustion engines, typically convert chemical energy into mechanical energy. The engine is suitable for the power generation device, and can also refer to the whole machine (such as a gasoline engine and an aviation engine) comprising the power device.

External combustion engines, that is, their fuel is burned externally of the engine, invented in 1816 by r. The engine converts the heat energy generated by the combustion into kinetic energy, the watt-improved steam engine is a typical external combustion engine, when a large amount of coal is combusted to generate heat energy to heat water into a large amount of water vapor, high pressure is generated, and then the high pressure pushes the machine to do work, so that the conversion of the heat energy into the kinetic energy is completed. Internal combustion engines, i.e. reciprocating piston engines, differ from external combustion engines in that their fuel is burnt in the interior thereof. The internal combustion engines are very diverse, and common gasoline engines and common diesel engines are typical internal combustion engines. The gas turbine has the working characteristics that high-pressure gas is generated by combustion, and the high pressure of the gas is utilized to push the blades of the gas turbine to rotate, so that power is output. Gas turbines are used in a wide range, but since it is difficult to finely adjust the output power, automobiles and motorcycles rarely use gas turbines, and only some racing vehicles use gas turbines.

Jet engines are engines that generate reactive thrust directly from the high velocity jet stream of a nozzle. Widely used as power devices for aircrafts. The fuel and oxidant chemically react in the combustion chamber to release thermal energy, which is then converted in the nozzle to a function of conditioning the gas stream. In addition to fuel, oxidants carried by aircraft are known as rocket engines, including solid-fuel rocket engines and liquid-fuel rocket engines.

In recent years, the traditional reciprocating engine needs time, is intermittent, has insufficient smooth output and has large friction loss, large noise, large oil consumption and small power caused by compression ignition explosion, and the traditional reciprocating engine has high energy consumption and high pollution emission and is widely paid attention. Therefore, it is highly desirable to provide an engine that can output kinetic energy efficiently, continuously, and stably.
