Abstract

The invention provides a modified constant-pressure charging system and belongs to the technical field of internal combustion engines. The modified constant-pressure charging system comprises an engine intake pipe, a supercharger, an engine, an engine exhaust pipe, a turbine, connecting pipes, adjusting cavities, a moving plate, a spring, fixing plates and a rotary shaft, wherein the first adjusting cavity and the second adjusting cavity are coaxially connected through the rotary shaft, the spring is arranged on the counter-clockwise rotating side of a second rotating plate and is connected with the second rotating plate and the second fixing plate, one end of the second connecting pipe is communicated with the second adjusting cavity, and the other end of the second connecting pipe is communicated with the engine exhaust pipe between a catalyst pack and a silencer. 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.

Description

technical field [0001] The invention belongs to the technical field of internal combustion engines, and in particular relates to a modified constant-pressure supercharging system capable of realizing the self-regulation of the volume of the exhaust pipe of the supercharging 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 ...
