In the modified constant-pressure charging system, when the engine operates under the high-speed working condition, the front exhaust volume of the turbine is larger, pumped gas loss is low, and oil consumption is lower. When the engine operates under the low-speed working condition, the front exhaust volume of the turbine is smaller, pulse energy can be fully utilized, and oil consumption is lower. The modified constant-pressure charging system is reasonable in design, simple in structure and suitable for optimization design of a turbo-charging engine exhaust system.

The invention belongs to the technical field of internal combustion engines and relates to a before-the-turbine fluid self-control unit comprising an engine intake pipe, a turbocharger, an engine, an engine exhaust pipe, a turbine, connecting pipes, an adjusting cavity, a rotating shaft, a rotating plate, a control cavity, internal pipes, a spring and a rotator. The adjusting cavity and the control cavity are coaxially connected through the rotating shaft. The upper wall face of the second internal pipe is connected to a partition through the spring. One end of the second connecting pipe is communicated with an inner cavity of the control cavity. The other end of the second connecting pipe is connected to the engine exhaust pipe arranged between the turbine and a catalyst capsule. When the engine runs at high speed, volume of before-the-turbine displacement is high, pumping loss is low, and oil consumption is low; when the engine runs at low speed, volume of before-the-turbine displacement is low, pulse energy can be made full use, and oil consumption is low. The before-the-turbine fluid self-control unit is reasonable in design and simple in structure and is applicable to optimal design of an exhaust system of a turbocharged engine.
