Independent displacement volume controllable system

Abstract

The invention belongs to the technical field of internal combustion engines, and discloses an independent displacement volume controllable system which comprises air inlet pipes of an engine, a supercharger, the engine, exhaust pipes of the engine, a turbine, connecting pipes, adjusting cavities, movable plates, a spring, fixed plates and a rotary shaft. The first adjusting cavity and the second adjusting cavity are coaxially connected with each other by the rotary shaft, the spring is arranged on a clockwise rotation side of the second rotary plate and is connected with the second rotary plate and the second fixed plate, one end of the second connecting pipe is communicated with the second adjusting cavity, the other end of the second connecting pipe is communicated with the certain exhaust pipe of the engine, and the certain exhaust pipe of the engine is arranged between a catalysis pack and a silencer. The independent displacement volume controllable system has the advantages that the turbine is high in forward exhaust volume when the engine runs under high-speed working conditions, and accordingly pumping loss and oil consumption are low; the turbine is low in forward exhaust displacement when the engine runs under low-speed working conditions, accordingly, pulse energy can be sufficiently utilized, and the oil consumption is low; the independent displacement volume controllable system is reasonable in design, simple in structure and applicable to optimally designing exhaust systems of turbine supercharged engines.

Description

technical field [0001] The invention belongs to the technical field of internal combustion engines, and in particular relates to an independent exhaust volume controllable system capable of realizing the self-regulation of the exhaust pipe volume of a supercharged engine. Background technique [0002] The turbocharging system mainly includes a pulse supercharging system and a constant pressure supercharging system. In the constant-pressure supercharging system, each cylinder shares a large-volume exhaust pipe. The structure of the exhaust pipe system is relatively simple. The pressure in the exhaust pipe is basically kept constant, and the pressure is only related to the load and speed of the engine. The constant pressure supercharging system has less pumping loss, higher turbine efficiency and better performance under high-speed conditions; however, it cannot fully utilize the exhaust pulse energy under low-speed conditions. Pulse supercharging system, according to the fir...
