Abstract

The invention discloses an end surface air inlet device for a rotor engine and belongs to the field of engines. The end surface air inlet device comprises a crankshaft, a bearing, a first rotor, a bolt, a front end cover casing, a cylinder, a fourth bearing, an inner gear, an outer gear, a fifth bearing, a rear end cover, a second rotor, a first air inlet channel, a second air inlet channel, a third air inlet channel and a combustion chamber, wherein a front end cover comprises the front end cover casing and the first rotor, the first rotor is arranged in the front end cover casing, the third air inlet channel and the first air inlet channel are formed in the left side and the right side of the front end cover respectively, and the second air inlet channel is formed in the first rotor; a first bearing is matched with the first rotor, and a second baring and a third bearing are matched with the front end cover casing on the left side and the right side respectively; the third air inlet channel is located above the first air inlet channel; an air outlet of the third air inlet channel is larger than an air inlet; air inlet diameter of the second air inlet channel is larger than that of the first air inlet channel. With the adoption of the end surface air inlet device for the rotor engine, fluid resistance can be reduced, and air inflow can be increased, so that air charging coefficient and mean effective pressure are increased.

Description

technical field

[0001] The invention relates to auxiliary equipment for a micro-rotary engine, in particular to an end face air intake device for a rotary engine, which belongs to the field of engines. Background technique

[0002] With the development of micro-electro-mechanical systems (MEMS) and the introduction of a variety of miniaturized military equipment concepts, the development of micro-energy systems with small volume, light weight, high energy density, and continuous operation has become the focus of attention of various countries. Compared with conventional portable power sources, micro-engines use hydrocarbons as fuels, which have much higher energy density, stable voltage, and low cost. Therefore, micro-engines will have wide application prospects in electronic devices in various industries such as industry, agriculture, environmental protection, medical and health care, etc., and can also directly provide power for micro-machines such as micro-cars, micro-pla...
