The pie engine is in the shape of a round pie, and the machine body is fixed on the oil receiver by four bolts. The ratio of thickness to diameter of the machine body is about 1:5, and its inner ring (fixed part) consists of two half-moon working chambers and a rectangular piston. Four bolts pass through two half-moon working chambers to fix the inner ring. The rectangular piston is composed of a rectangular shell and a vertically movable lead core, and reciprocates linearly between two working chambers. Its unique structure keeps it in harmony with the rotating excircle. The outer ring (rotating part) consists of a heavy circular iron ring and circular guard plates buckled on both sides. There is an inclined flaky copper combustion chamber inside the iron ring, and there are two-way power transmission gears on the guard plates on both sides. The combustion chamber contacts one end of the piston once every half revolution of the excircle. During contact, the mixed gas is pressed into the combustion chamber, and the flaky combustion chamber passes through the horn electrode inserted into the top of the half-moon working chamber, and the mixed gas in the combustion chamber is ignited by the arc. The acting force generated by the gas explosion pushes the excircle to rotate along the parallel direction of the plate, pushes the piston to move in the opposite direction, and presses the mixed gas at the other end into the rotating combustion chamber to do work again.

technical superiority

(1) saves the cylinder, connecting rod, crankshaft, balance shaft, oil tank, cooling water tank, fan and other parts of the traditional engine, so it is small in size, light in weight, low in vibration, low in noise and low in energy consumption.

(2) The excircle rotates once and does work twice, and the operation is stable. Because there is no crankshaft rotation and violent oscillation of the connecting rod, the vibration of the machine body is small, the noise is low, the internal parts, especially the sealing plates at both ends of the piston, are less worn, and the service life is long.

(3) The movement of the excircle and the piston is completed by the thrust generated by gas expansion, unlike the traditional engine which consumes power in three of the four strokes, which greatly saves energy.

(4) The ignition is completed by the friction between the outer combustion chamber and the horn-shaped electrode protruding from the inner circle during the rotation, and the ignition time does not need to be corrected in advance, and the electrode does not need to be specially pressurized, which is accurate and reliable.

(5) The mixed gas is quickly discharged from the engine body after combustion, and the residence time ratio of mixed gas and cold air in the engine body is about 1:4, while the residence time ratio of hot and cold gas in the traditional engine body is about 1: 1. Therefore, the machine body is not easy to generate heat, and various low-ignition environmental-friendly fuels can be used without additional cooling devices.

(6) It can be made into various models, such as large, medium and small, which can be used singly or in combination, and can be turned on singly or in combination according to power requirements, thus further saving energy.

(7) It is an ideal power for hand-held tools such as sawing, drilling, planing, nailing and extinguishing wind, and machinery such as farming, weeding, pruning and spraying in agriculture, forestry and pastoral areas. When used on a motorcycle, it can make the motorcycle suddenly lose weight. When used in automobiles, it can effectively increase the load capacity of automobiles and make automobiles more portable, comfortable and energy-saving.

(8) The use of clean energy, long-distance exercise does not require frequent charging, and it can be used in vehicles such as cars and motorcycles, which can reduce a lot of troubles for drivers and avoid many restrictions.

The market prospect is promising and the economic benefits are considerable.

Direct-current infrared induction automatic luminous device for human body

Patent number: ZL 200720 199242.3

This patented product, referred to as "magic lamp" for short, is a practical new electronic automatic lamp and a novel electronic craft gift.
