Description

technical field [0001] The invention belongs to the technical field of engines, and relates to a bionic engine and a realization method thereof. Background technique [0002] There are many types of modern engines, and they also occupy various fields. Here, only the piston engine with high thermal efficiency is taken as an example, and the gasoline engine is used as a reference engine as follows: [0003] To measure the pros and cons of an engine, it is mainly thermal efficiency, which is the ratio of the effective work output by the engine to the total work produced by the working medium. The gasoline engine only has η=0.22-0.3, and the random sampling data of practical machines is 3-5% lower than this value , In terms of environmental impact, a 100KW engine emits 600kg of CO and 40kg of NO into the atmosphere within a year, and smoke and dust account for 3-8% of the exhaust. [0004] Influencing factors: [0005] 1. Cooling energy consumption is about 30%, the highest ca...

AI Technical Summary

Problems solved by technology

[0008] (2) The force receiving and receiving during the expansion stroke is not ideal. When the piston compresses to the top dead center, theoretically it is the beginning of ignition and expansion.

Expansion work cannot be effectively utilized

[0009] 3. Since the initial temperature of expansion reaches 2900K, it is very easy to produce NOx, and because of the uneven distribution of oxidant

Directly cause more than 4% fuel loss, become CO and soot emissions to pollute the environment

[0010] 4. Working fluid filling (filling quantity) coefficient ψ = 0.7-0.9, coupled with incomplete scavenging, complex mechanism, low space utilization, many parts and high precision requirements, and random coordination is difficult

[0011] 5. During the ventilation process, the temperature of the working medium changes sharply, and the frequency of the temperature change of the flow field is high, resulting in large creep of the cylinder liner and short engine life

[0012] 6. There are strict requirements on fuel, limited by the seasonal and geographical environment, and the scope of use is narrow

[0013] 7. The effective work output of the piston is intermittent, that is, the utilization rate of the working time is less than 15%.

However, it works at high temperature, the temperature gradient is large, the linear dimension difference of matching parts is large, the expansion is different, the curved surface is matched at many points, and the sealing is difficult, resulting in air leakage between flow fields, loss of pressure, and loss of control

Unlike gear meshing, single pitch diameter, conformal curved surface, less relative sliding, and press 1 / 2 n The positive pressure of the recursive principle is compensated by mutual elastic deformation, but this kind of body sealing is an insurmountable obstacle

Although the gas turbine also operates in one direction as a rotating working medium, the flow field (the place where the working medium works or accumulates) has many and complicated components, requires high-temperature heat-resistant alloys, is difficult to manufacture, has high noise, and lower thermal efficiency. Part of the kinetic energy, working fluid potential energy and internal energy are basically not used
