Abstract

The invention provides a controllable turbine air discharging system, and belongs to the technical field of internal combustion engines. The system comprises an air discharging tube, a rotating shaft, a rotating plate, an adjusting rod, a control cavity, a spring, a moving body, a first control tube and a second control tube; one end of the first control tube passes through the right wall surface of the control cavity to be communicated with an inner cavity; the other end of the first control tube is communicated with an air exhaust tube between an engine and a turbine; one end of the second control tube passes through the left wall surface of the control cavity to be communicated with the inner cavity, while the other end of the second control tube is communicated with the air exhaust tube between the turbine and a muffler. According to the system, the air discharging rate of the turbine is large while the engine has a large load; the air discharging rate of the turbine is small while the engine has a small load. The system is reasonable in design, simple in structure, and suitable for design of a diesel engine turbine boosting system.

Description

technical field

[0001] The invention belongs to the technical field of internal combustion engine design, in particular to a controllable turbine deflation system capable of realizing self-regulation of the 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 o...
