Abstract

A rotation control type air exhaust pipe outlet area variable device belongs to the technical field of mechanical design and comprises an air compressor, an engine, an air exhaust pipe, a turbine, a volume cavity, a rotation body, a spring, a connection pipe, a rotation rod, a rotation shaft and a rotation plate. The longitudinal sections of the volume cavity and the rotation body are both in arc shapes, the rotation plate is installed in the air exhaust pipe, the rotation plate and the rotation shaft are fixed together, the left wall of the rotation body is connected with the left wall of the volume cavity through the spring, and two ends of the connection pipe are respectively communicated with the right wall of the volume cavity and the air exhaust pipe. When pressure in the air exhaust pipe in front of the rotation plate is high, the rotation body drives the rotation plate to rotate in a counterclockwise mode, pumping loss of the engine is small, and the whole performance is excellent. When pressure in the air exhaust pipe in front of the rotation plate is low, the rotation body drives the rotation plate to rotate in a clockwise mode, available energy in front of the turbine is more, air inlet pressure of the engine is high, and the whole performance is excellent. The rotation control type air exhaust pipe outlet area variable device is reasonable in design, simple in structure and suitable for a turbine single inlet turbocharged system.

Description

technical field [0001] The invention relates to a turbocharging system in the technical field of mechanical design, in particular to a rotary control type exhaust pipe outlet area variable 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 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 sy...
