Description
Technical Field
The invention belongs to the technical field of engine maintenance, and particularly relates to an engine maintenance method.
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 a power generation device, and can also refer to the whole machine (such as a gasoline engine and an aircraft engine) comprising the power device. Engines were first introduced in the united kingdom, and the engine concept is also derived from english, which is meant in its meaning as "power generating machinery".
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 engine is characterized in that high-pressure gas is generated by combustion, and the high pressure of the gas is used for pushing blades of the gas turbine to rotate so as to output power. 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 of air from a jet. 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.
