AI Technical Summary

Technical Problem

The existing EGR valve causes exhaust gas to rush directly into the intake manifold when the engine is running, resulting in unstable intake speed and oxygen ratio, leading to incomplete combustion of gasoline in the engine.

Method used

An adjustment component is used to control the amount of exhaust gas entering and the oxygen ratio. Through the cooperation of hydraulic rods and lifting valves, the mixing ratio of exhaust gas and oxygen is adjusted to ensure a uniform and stable combustion process.

Benefits of technology

It achieves stable mixing of exhaust gas and oxygen, improves combustion efficiency, ensures stable gas entry into the engine, and achieves high efficiency and energy saving.
