Abstract

The invention belongs to a volume cavity regulating type exhausting device in the technical field of internal combustion engines. The volume cavity regulating type exhausting device comprises an air releasing pipe, a rotating shaft, a rotating plate, a regulating rod, a control cavity, a spring, moving bodies and a control pipe, wherein the rotating shaft is embedded in an exhaust circulating pipe; one end of the rotating plate and the rotating shaft are fixedly connected together; the cross sections of a first moving body, a second moving body and a third moving body are respectively provided with a slope structure and are mutually matched; one end of the control pipe is communicated with a cavity between the first moving body and the second moving body after penetrating through the upper wall surface of the control cavity; the other end of the control pipe is communicated with an exhausting pipe between an engine and a turbine. In the volume cavity regulating type exhausting device disclosed by the invention, when the load of the engine is larger, the air releasing amount of the turbine is larger; when the load of the engine is smaller, the air releasing amount of the turbine is smaller. The volume cavity regulating type exhausting device is reasonable in design, simple in structure and suitable for designing of an engine turbo-charging system.

Description

technical field

[0001] The invention belongs to the technical field of internal-combustion engine design, in particular to a volume cavity-adjustable gas-bleeder capable of realizing self-regulation of turbine deflation. Background technique

[0002] Turbocharging is a technology that uses the exhaust gas generated by the operation of an internal combustion engine to drive an air compressor. The main function of turbocharging is to increase the air intake of the engine, thereby increasing the power and torque of the engine and making the car more powerful. After an engine is equipped with a turbocharger, its maximum power can be increased by 40% or even higher compared with that without a supercharger. This also means that the same engine can output more power after being supercharged. Take our most common 1.8T turbocharged engine as an example. After supercharging, the power can reach the level of a 2.4L engine, but the fuel consumption is not much higher than that of a 1...
