Oxygen intake type single stroke engine and operation method thereof

Abstract

An oxygen-entering type single-stroke engine is provided. Wherein, on an air-intake port of an air-intake valve of a cylinder, one end of a compressed oxygen intake pipe is connected, another end of the intake pipe is connected with an oxygen storage tank and an adjustable air valve; the air intaker, an air exhaust valve, an oil injection nozzle and the devices of switches on a spark plug match each other: a piston moves from the lower stop to the upper stop, the air exhaust valve opens to the upper stop, the exhaust valve closes, the air intake valve opens instantaneously, oxygen enters, meanwhile the oil injection nozzle opens, the air intake valve and the oil injection nozzle close instantaneously before ignition; the engine ignites, the piston moves to the lower stop. The invention additionally provides the operation way for the oxygen-entering type single-stroke engine. The oxygen-entering type single-stroke engine provided in the invention realizes a single-stroke no-compression high-efficiency operation mode by inputting oxygen of high concentration in the air intake valve. The device supplying oxygen of high concentration is only a set of oxygen tank and a hi-concentration oxygen delivery pipeline, and is of very simple structure. The engine combines and improves the functions of prior engines, is of high operation efficiency, full combustion and low energy consumption.

Description

technical field [0001] The invention belongs to the technical field of engines, in particular to an oxygen-injected single-stroke engine. The invention also provides a method for operating the single-stroke engine accompanied by gas input during the working phase. Background technique [0002] Motors in the prior art generally include four working processes: air intake, compression, explosion (ignition and fuel injection) and exhaust. The crankshaft rotates for two weeks to complete a work cycle and perform work once, and the efficiency is low. In order to improve work efficiency, a two-stroke gasoline engine appears in the prior art. The crank of the two-stroke engine rotates 360° to complete a working cycle, that is, the engine burns once when the crank rotates one circle. It relies on the scavenging port on the cylinder wall, the exhaust The port completes the intake and exhaust process. Because the crank of a two-stroke engine rotates one revolution to do one work, the...

AI Technical Summary

Problems solved by technology

Because the crank of a two-stroke engine rotates one revolution to do one work, the torque of the two-stroke engine is more uniform than that of the four-stroke engine; at the same time, under the same crankshaft speed and the same working volume, the output power of the two-stroke engine is twice as high as that of the four-stroke engine , but because the two-stroke engine has scavenging loss, and the effective working stroke is reduced during ventilation, its actual output power is only 50% to 70% higher than that of the four-stroke engine

In addition, the two-stroke gasoline engine in the prior art also has the following defects: 1, the work is rough, gasoline will be mixed with lubricating oil, so that the life of the engine is reduced; 2, the combustion is insufficient, and the emission pollution is serious

[0003] To sum up, it can be seen that the engine in the prior art always needs to go through a compression process, which consumes energy and reduces the efficiency of the engine
