Abstract

The invention relates to an air pressure type gas relief system, belonging to the technical field of an internal combustion engine. The air pressure type gas relief system comprises an exhaust pipe, a rotating shaft, a rotating plate, an adjusting rod, a control cavity, a spring, a movable bodies and a control pipe, wherein the rotating shaft is embedded on an exhaust circulating pipe; one end of the rotating plate is fixedly connected with the rotating shaft; the longitudinal sections of the first movable body, the second movable body and the third movable body respectively have a slope structure and are matched with one another; one end of the control pipe passes through the upper wall of the control cavity and is communicated with a cavity between the first movable body and the second movable body; the other end of the control pipe is communicated with an air inlet pipe between a gas compressor and an engine. According to the air pressure type gas relief system, when the load of the engine is higher, a turbine has higher outgassing amount; when the load of the engine is lower, the turbine has lower outgassing amount. The air pressure type gas relief system is reasonable in design and simple in structure, and is suitable for the design of an engine turbocharging system.

Description

technical field

[0001] The invention belongs to the technical field of internal-combustion engine design, and in particular relates to a pneumatic deflation system 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...
