Description

Mechanical adjustment system with through-tube in the fixation body

technical field

The invention relates to a turbocharging system in the technical field of mechanical design, in particular to a mechanical adjustment system with a through pipe in a fixed body.

Background technique

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 an exhaust pipe with a large volume, the structure of the exhaust pipe system is relatively simple, the pressure in the exhaust pipe is basically kept constant, the pressure is only related to the load and speed of the engine, different cylinder numbers The supercharging system of the diesel engine can be designed uniformly. The constant pressure supercharging system has less pumping loss, higher turbine efficiency and better performance under high-speed conditions; however, it cannot fully utilize the exhaust pulse energy under low-speed conditions. Pulse supercharging system, according to the firing sequence of each cylinder, connects two cylinders or three cylinders that do not interfere with the exhaust with the same exhaust pipe. The diameter of the exhaust pipe system is small, and the exhaust pulse energy can be fully utilized , the low-speed working condition and the transient working condition have better performance; but in the high-speed working condition, the pumping loss is larger. It can be seen that if the volume of the exhaust pipe of an engine can change with the change of working conditions, the volume of the exhaust pipe will be enlarged under high-speed conditions, and the volume of the exhaust pipe will be reduced under low-speed conditions. ideal. On the premise that the volume of the exhaust pipe remains unchanged, by changing the outlet area of the exhaust pipe, it is also possible to achieve both high and low engine speed conditions. In low-speed conditions, the outlet area of the exhaust pipe becomes smaller, and more energy is available before the turbine; in high-speed conditions, the outlet area of the exhaust pipe becomes larger, and the pumping loss is smaller, which is also ideal.
