AI Technical Summary
Technical Problem
Existing combustion engines are unable to flexibly adjust displacement when load changes, resulting in insufficient power output and low reliability.
Method used
By introducing a variable valve timing system into the engine, the timing of the upper intake valve, upper exhaust valve and main valve can be independently controlled to achieve flexible adjustment of the engine displacement.
Benefits of technology
It enables the engine to flexibly switch between high output and high power density and low output and low fuel consumption, extending the service life of engine components and improving reliability.

Abstract
A combustion engine includes a main combustion cylinder configured to allow a piston to move therein; a main valve configured to move within the main combustion cylinder; the upper non-combustion chamber is operably adjacent to the main combustion cylinder; the upper air inlet valve is configured to move in the upper non-combustion chamber and is communicated with an air inlet manifold; and an upper exhaust valve configured to move within the upper non-combustion chamber and in communication with an exhaust manifold.
