Abstract

The invention discloses an air inlet pressure main control type pipeline device, and belongs to the technical field of mechanical design. The air inlet pressure main control type pipeline device comprises air compressors, an air inlet pipe, an engine, an air exhaust pipe, turbines, a volume cavity, a connection pipe, a moving body, a spring and penetration pipes, wherein the moving body is arranged in the volume cavity and is in sealing contact with the inner wall surface of the volume cavity; the first penetration pipe and the second penetration pipe penetrate through the upper wall surface and the lower wall surface of the moving body; and the right wall surface of the moving body is connected with the right wall surface of the volume cavity through the spring. When the engine is in a high-speed working condition, the moving body moves rightwards, the first air compressor, the second air compressor, the first turbine and the second turbine work synchronously, the air pumping loss of the engine is relatively low, and the overall performance of the engine is relatively high; and when the engine is in a low-speed working condition, the moving body moves leftwards, only the first air compressor and the first turbine work, pulse energy is fully used, the air inlet pressure of the engine is relatively high, and the overall performance of the engine is relatively high. The air inlet pressure main control type pipeline device is rational in design, simple in structure and suitable for turbine pressurization systems with double turbines and double air compressors.

Description

technical field [0001] The invention relates to a turbocharging system in the technical field of mechanical design, in particular to an intake pressure main control pipeline device. 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 related ...
