Array type centrifugal body distribution system

Abstract

An array type centrifugal body distribution system belongs to the technical field of mechanical design and comprises an adjusting body, a rotating shaft, a rotator, a stretching body, centrifugal bodies, balls, a pull rod and springs; the rotating shaft and the rotator are fixedly connected with each other; both of the stretching body and the centrifugal bodies are distributed in the rotator; the balls are embedded on the stretching body; one side wall of each centrifugal body is in contact with the stretching body through the corresponding ball; the other side walls of the centrifugal bodies are connected with the internal wall surface of the rotator through the first springs; and the top end of the stretching body is connected with the internal wall surface of the rotator through the second spring. According to the system, when the rotate speed of an engine is higher, an adjusting plate moves upward, the total capacity of an exhaust pipe before a turbine is larger, and the pumping loss is less; and when the rotate speed of is engine is lower, the adjusting plate moves downward, the total capacity of the exhaust pipe before the turbine is less, and exhaust pulse energy can be fully utilized. The distributed system is reasonable in design, simple in structure and suitable for the optimal capacity design of the exhaust pipe in a turbo-charging system.

Description

technical field

[0001] The invention relates to an array type centrifugal body distribution system in the technical field of mechanical design, in particular to an array type centrifugal body distribution system suitable for a turbocharged engine exhaust system. Background technique

[0002] The turbocharging system mainly includes a pulse supercharging system and a constant pressure supercharging system. In the constant-pressure supercharging system, each cylinder shares a large-volume exhaust pipe. The structure of the exhaust pipe system is relatively simple. The pressure in the exhaust pipe is basically kept constant, and the pressure is only related to the load and speed of the engine. 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 sequen...
