Piston assembly for novel engine and novel engine

Abstract

The invention relates to the technical field of engines, in particular to a piston assembly for a novel engine and the novel engine. The piston assembly comprises a piston and a variable hollow air valve, wherein a cross-shaped supporting frame is arranged in the middle of the piston, an air valve through hole is formed in the middle of the cross-shaped supporting frame, a plurality of matching lugs are arranged on the cross-shaped supporting frame, a valve seat is arranged at the position, between the piston and the end matching with the variable hollow air valve, of the piston, the variablehollow air valve comprises a hollow air valve body and a valve rod, a first annular groove is formed in the middle of the hollow air valve body and provided with a plurality of first deflation throughholes, a second annular groove is formed in the middle of the first annular groove, a plurality of matching through holes are formed in the second annular groove, the plurality of matching lugs penetrate through the plurality of matching through holes and are provided with a circle center valve seat, and a hollow plugging circular ring is further arranged on the first annular groove. The piston assembly for the novel engine and the novel engine have the advantages that exhaust is cleaner, mechanical friction is reduced, an intake valve is controlled in time, the compression ratio is variable,the heat efficiency and power are improved, and a two-stroke linear internal combustion engine exhaust Atkinson technology is used.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a piston assembly for a novel engine and a novel engine. Background technique [0002] Engine A machine that can convert other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, electric motors, etc. For example, internal combustion engines usually convert chemical energy into mechanical energy. The engine is not only applicable to the power generating device, but also refers to the whole machine including the power device. [0003] At present, most of the car engines on the market are four-stroke engines, and there is a new type of Israeli engine, which is a two-stroke engine. The principle is that a piston moves back and forth in the cylinder to make the internal gas compress and ignite. In this way, the chemical energy is converted into mechanical energy through back and forth compression ignition, the piston drives th...

Problems solved by technology

[0004] However, this single-cylinder engine has the following problems: (1) Both ends of the piston do work through gasoline combustion, so it is impossible to achieve oil injection lubrication, and it can only be lubricated by mixing engine oil in gasoline, resulting in high cost of use, and the oil burns when it is discharged. Poor discharge; (2) The piston ring needs to pass through the intake valve, which increases the f
