Problems solved by technology

The shape of the cylinder formed by the triangular rotor is narrow and long, which reduces the combustion efficiency
But its disadvantage is fatal. The turbojet engine relies on the high-speed rotation of the high-speed rotor, and uses the high-pressure jet air flow to generate thrust. Its fuel consumption is quite high, which makes the aircraft model stay in the air for a shorter time. In addition, the life of the engine is shorter than that of ordinary engines. a lot of
When manufacturing, the materials used and processing difficulty are more difficult than ordinary engines, and it is also difficult to apply to low-temperature environments or fuel cells with low fuel consumption

Embodiment Construction

[0029] 1. Various parts of the engine

[0030] Such as figure 1 As shown, it is a schematic diagram of the appearance of the whole machine. From the figure, it can be clearly understood that the engine is a cylinder. side. The engine is provided with two air ports on the circumferential surface of the cylinder, which are respectively an air inlet and an exhaust port. The air port is located on one side of the circumferential surface, and a glow plug is installed on the other side to be responsible for ignition. Bolts are installed around the engine to fix the whole machine.

[0031] Such as figure 2 As shown, it is a schematic diagram of the internal dissection of the whole machine, from which the main technical features of the present invention can be clearly understood, wherein the output shaft (1) passes through the upper cover (9) and the lower cover (10) and can be inside the body Rotate, the gear shaft (2) is parallel to the output shaft (1) and is fixed between the...

Abstract

The invention relates to a mini elliptic gear engine with a few of components. The complete engine is in the shape of a cylinder and is fixed by housing bolts; a transmitting system consisting of an output shaft, a gear shaft, an up-down duplicate gear and inner gears on rotors is arranged in the engine; the engine cylinder comprises two opposite rotors and an inner wall of the shell; and the ignition system and the gas exchange system comprise a thermal fire head and a air inlet/outlet on the shell. When the elliptic gear of the output shaft, the duplicate gear and the inner gears of the rotors are meshed with each other, the periodic variation of a force arm between the two rotors and the output shaft will occur so as to push the output shaft to rotate by the gas expansion force, thus forming the engine.

Description

a technical field [0001] The invention relates to a micro-engine with a transmission system composed of oval gears, in particular to a micro-four-stroke engine with few components, no connecting rod mechanism, no vibration in operation, and applicable to model airplanes or fuel cells. Two background technology [0002] Among the existing micro-engines, the ones with relatively mature technology are mainly micro-single-cylinder piston engines, micro-triangular rotor engines, and micro-turbojet engines, among which the single-cylinder piston engines are derived from the reduced volume of motorcycle two-stroke engines. Although its development has experienced decades, due to the defects of the two-stroke engine itself, there will inevitably be many problems in the miniature piston engine. For example, the use of two-stroke ventilation makes it seriously polluted, and some combustible gases are discharged without being ignited, causing excessive fuel consumption. Each combustion...
