Laterally mounted exhaust volume adjusting device

Abstract

The invention provides a laterally mounted exhaust volume adjusting device, and belongs to the technical field of internal combustion engines. The laterally mounted exhaust volume adjusting device comprises an engine air feeding tube, a supercharger, an engine, an engine exhaust tube, a turbine, connecting tubes, adjusting cavities, moving plates, a spring, fixed plates and a rotating shaft, wherein the first adjusting cavity is coaxially connected with the second adjusting cavity through a rotating shaft; the spring is arranged on a clockwise rotation side of the second rotating plate and is connected with the second rotating plate and the second fixed plate; one end of the second connecting tube is connected with the second adjusting cavity; and the other end of the second connecting tube is connected with the engine air feeding tube between a compressor and an intercooler. In the laterally mounted exhaust volume adjusting device, when the engine runs under the working condition of high speed, the front exhaust volume of the turbine is large, pumping loss is low, and oil consumption is also low; and when the engine runs under the working condition of low speed, the front exhaust volume of the turbine is small, pulse energy can be sufficiently utilized, and the oil consumption is low. The laterally mounted exhaust volume adjusting device is reasonable in design and simple in structure, and is suitable for the optimization design of an exhaust system of a turbocharged engine.

Description

technical field [0001] The invention belongs to the technical field of internal combustion engines, and in particular relates to a side-mounted exhaust volume adjustment device capable of realizing self-adjustment of the volume of an exhaust pipe 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...
