Abstract

A switching system between a single turbine and double turbines relates to the technical field of mechanical design and comprises air compressors, an air inlet pipe, an engine, an air exhaust pipe, turbines, a volume cavity, a connection pipe, a movable body, a spring and a communication pipe. The movable body is installed in the volume cavity and is in sealing contact with the inner wall of the volume cavity, and the left wall of the movable body is connected with the left wall of the volume cavity through the spring. When pressure in the air inlet pipe of the engine is high, the moveable body can move towards right, a first air compressor, a second air compressor, a first turbine and a second turbine can work simultaneously, pumping loss of the engine is small, and whole performance of the engine is excellent. When pressure in the air inlet pipe of the engine is low, the moveable body moves towards left, only the first air compressor and the first turbine work, pulse energy is fully utilized, air inlet pressure of the engine is high, and whole performance of the engine is excellent. The switching system is reasonable in design, simple in structure and suitable for turbine boost 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 a switching system between a single turbo and a twin turbo. 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 ...
