Hybrid cylinder, hybrid engine and control method

Abstract

The invention discloses a hybrid cylinder. The hybrid cylinder comprises a cylinder body which is divided into an oil chamber and a piston of an air chamber which are distributed from top to bottom; first side air holes are formed in the bottom of the side wall of the air chamber; through the first side air holes, compressed air is injected into the air chamber or internal air is discharged to a compressed air collecting part; first bottom air holes are formed in the bottom of the air chamber; and through the first bottom air holes, air discharge in the later stage of compression is realized. The hybrid cylinder provided by the invention has the advantages that the oil chamber and the air chamber of an internal combustion engine are integrally arranged from top to bottom, so that the high temperature of the oil chamber during work time and the compressed air injected into the air chamber are effectively utilized for expansion work, and the expansion work of the compressed air can be achieved while the temperature of the cylinder body of the hybrid cylinder is lowered, that is, the compressed air is utilized for auxiliary work during an exhaust stroke of the oil chamber, thereby effectively improving the overall efficiency; and meanwhile, the internal energy of the first half of the downward movement of the piston is huge after ignition of the oil chamber, so that the internal energy can be sufficiently utilized to compress air in the air chamber for preparation and storage of the compressed air, and the engine power can be output more stably.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a hybrid cylinder, a hybrid engine and a control method. Background technique [0002] The air-fuel hybrid engine is produced by combining the advantages of zero emission of the air engine and overcoming the weakness of the high energy consumption and high pollution of the fuel engine. So far, there have been many forms of air-fuel hybrid engine patents, but the technical inventions with real specific application prospects have not yet appeared. As for the reason, it should be that the existing air-fuel hybrid engine, the guiding ideology of its technical invention, is only limited to improving the existing fuel engine, and has not made any improvements to the existing fuel engine technology in terms of energy saving and pollutant discharge. Fundamental change. [0003] For example: Chinese patents 02111984.8, 200710067863.0 and patent application 201510304471.6, etc., use heat...

AI Technical Summary

Problems solved by technology

[0007] To sum up, the existing air-fuel hybrid engines are only limited to improving the existing fuel engines, and all use one-way thrust cylinders. The number of cylinders is small, and the functional configuration cannot be performed. Therefore, there is no improvement in energy saving and pollutants. Fundamental changes to existing combustion engine technology in terms of emissions
