Problems solved by technology

However, the essence of the micro-engine is to shrink the structure of the macro-scale heat engine. The establishment of the corresponding macroscopic heat engine in terms of mechanical similarity and thermal similarity, and its experimental results also prove that its thermal efficiency and output power are far from meeting the requirements of ultra-high energy density (expected output power 125w, actual output power 2.7w)

Embodiment Construction

[0028] Below in conjunction with accompanying drawing, micro-engine of the present invention is described in further detail.

[0029] The micro-engine comprises an inner cam flywheel disc 1, a slide block 2, a cylinder body 3, a piston rotating shaft 4, a cover plate 5, an air transmission mechanism 9 and a probe type spark plug 8. Fig. 1~Fig. 4 have shown the positional relation of each part when this engine intake combustion, there is a fan-shaped bump type piston on the circumference of the side middle part of piston rotating shaft 4, and the center line of this piston is parallel to the horizontal line, and inner cam flywheel disc 1 The centerline of the movable sliding block 2 is located on the horizontal center line of the piston shaft and the right side of the sliding block 2 is movably matched with the outer side of the piston shaft 4; The upper end of the cylindrical pin on the slider 2 is located in the annular groove of the inner cam flywheel disc 1, and the movemen...

Abstract

A tiny engine, in particular a tiny engine based on quasi - forces of gas flow circulating principle makes motor outputting power reach superhigh energy density. Tiny engine includes inner cam flywheel disk, slipper, cylinder body, piston rotor shaft, cover board, gas transmission mechanism and probe type spark plug. Said space in piston rotor shaft is premixing chamber for feeding high pressure gas fuel to cylinder body firing chamber, thereby realizing the thermodynamics effect through pre-set premix high pressure gas fuel form to substitute perfect gas power cycle constant entropy adiabatic compression process. Said invention has higher output loop net work, higher energy density and more simple system structure.

Description

technical field [0001] The invention relates to an engine, especially a micro engine based on the principle of quasi-gas power cycle. Background technique [0002] In recent years, the development of high-energy MEMS in the world is very rapid. At the International Mechanical Engineering Conference held in New York, USA in 2001, the article MEMS-23924 introduced a miniature rotary Wankel engine developed by the University of California in the United States. The triangular rotor rotating in the inner cavity is composed of a gas delivery mechanism and a probe type spark plug; due to the use of an eccentric device, there is a certain position offset between the center line of the rotor and the center line of the inner cavity, when the rotor revolves around the center of the eccentric device When rotating, the three vertices of the rotor are always in contact with the side wall of the inner cavity and form three closed combustion chambers; since the rotor and the eccentric devi...
