Embodiment Construction

[0017] The technical scheme of the present invention is described in three parts according to the method of injecting oxygen in the cylinder, the internal combustion engine with oxygen injection in the cylinder, and the control method of oxygen-enriched combustion of the internal combustion engine.

[0018] In-cylinder oxygen injection method: a method for injecting oxygen-enriched gas into the cylinder of an internal combustion engine. On each cylinder combustion chamber of an existing internal combustion engine, at least one intake valve (can be an intake valve of the prior art, or But electromagnetic valve or electronic valve), the outlet of the added intake valve is communicated with the interior of the combustion chamber, equipped with oxygen-generating equipment to supply oxygen-enriched gas to the added intake valve, through the opening and closing control of the intake valve, Oxygen-enriched gas is injected into the combustion chamber during a certain period of time dur...

Abstract

This is an invention of an inside cylinder oxygen injection internal combustion engine and its oxygen rich combustion control method. On each cylinder's combustion chamber installs at least one oxygen rich inlet port, the outlet of the port links to the combustion chamber, and the inlet of the port links to the outlet of a back flow valve, the inlet of the back flow valve links to the main pipe of the oxygen rich supply. The main pipe links to an oxygen generation device. By controlling the open and close of the port, injecting oxygen rich gas during the stage of inspiration or gas exchange, compressing, combustion to increase the fuel's combustion and so increase power output and decrease the exhaustion of NOx, CH, PM. This inversion consumes only 30% of oxygen rich gas of traditional engine under the same oxygen level. The oxygen generation device is of small size, light in weight, low energy consumption and low cost. It can be used in any kinds of two strokes and four strokes internal combustion engine.

Description

technical field [0001] The invention relates to an engine, in particular to an internal combustion engine which additionally injects oxygen-enriched gas into a cylinder and an oxygen-enriched combustion control method thereof. Background technique [0002] In modern society, whether it is a diesel engine or a gasoline engine, its combustion is not sufficient, which has caused serious pollution to the atmospheric environment, caused the excessive consumption of limited oil resources, and caused human beings to face a serious energy crisis. Saving energy, building a conservation-minded society and protecting the environment are major issues facing the engine industry. However, any internal combustion engine does work by mixing fuel and oxygen in the air. The oxygen content in the air is only 21%, and the remaining 79% is nitrogen and a small amount of other gases, which do not work on combustion and cause internal combustion. The engine has been workin...
