Intercooler front engine inlet air leading-out equipment

Abstract

The invention discloses intercooler front engine inlet air leading-out equipment belonging to the technical field of internal combustion engines. The intercooler front engine inlet air leading-out equipment comprises an engine air inlet pipe, a supercharger, an engine, an engine exhaust pipe, a turbine, connecting pipes, a regulating cavity, a rotating shaft, a rotating plate, a control cavity, inner pipes, a spring, a rotator and a stressed plate, wherein the regulating cavity and the control cavity are coaxially connected through the rotating shaft; the stressed plate is connected together with the left wall surface of a fixation body through the spring; and one end of the second connecting pipe is communicated with the first inner pipe after passing through the fixation body, and the other end of the second connecting pipe is connected with the engine air inlet pipe located between a compressor and an intercooler. According to the intercooler front engine inlet air leading-out equipment, when the engine operates at a high speed, the exhaust capacity of the front of the turbine is relatively high, the pumping loss is relatively low, and the oil consumption is relatively low; and when the engine operates at a low speed, the exhaust capacity of the front of the turbine is relatively low, the pulse energy can be sufficiently utilized, and the oil consumption is relatively low. The intercooler front engine inlet air leading-out equipment is reasonable in design, simple in structure and suitable for optimal 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 device for leading out an air intake of an intercooled front engine which can realize self-regulation 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, a...
