Horizontal moving mechanical regulation system

Abstract

A horizontal moving mechanical regulation system in the technical field of combustion engines comprises compressors, a gas inlet pipe, an engine, an exhaust pipe, turbines, a volume cavity, a connection pipe, a moving body, a spring and a through pipe; the moving body is mounted in the volume cavity and is in sealed contact with the inner wall surface of the volume cavity, the through pipe penetrates through the upper and lower wall surfaces of the moving body, and the left wall surface of the moving body is connected with the left wall surface of the volume cavity through the spring. When the engine in a high speed work condition, the moving body moves towards the right, the first compressor, the second compressor, the first turbine and the second turbine works at the same time, so that the pumping loss of the engine is less and the performance of the whole engine is better; when the engine is in a low speed work condition, the moving body moves towards the left, only the first compressor and the first turbine work, so that the pulse energy is fully used, the gas inlet pressure of the engine is higher, and the performance of the whole engine is better. The horizontal moving mechanical regulation system is reasonable in design and simple in structure, and is applicable to a turbine pressurization system with dual turbines and double compressors.

Description

technical field [0001] The invention relates to a turbocharging system in the field of internal combustion engines, in particular to a left and right moving mechanical adjustment system. Background technique [0002] With the development of society and the improvement of environmental protection requirements, the application of engine supercharging technology is becoming more and more extensive. Most of the engines with medium and high power adopt turbocharging technology to improve power and reduce fuel consumption. The two basic types of turbocharging systems are constant pressure supercharging system and pulse supercharging system. Constant-pressure supercharging system, each cylinder shares a large-volume exhaust pipe, the structure of the exhaust pipe system is relatively simple, the equivalent flow area of ​​the turbine is relatively large, the pressure in the exhaust pipe is basically kept constant, and the pressure is only related to the load of the engine It is rel...
