Abstract

The invention discloses a turbine exhaust device with a penetrating pipe in the technical field of internal combustion engines. The device comprises a compressor, a turbine, an engine, a connecting pipe, a volume cavity, a moving body, the penetrating pipe and an elastic part, wherein two ends of a first connecting pipe are respectively communicated with an exhaust pipe of the engine and the upper wall surface of the volume cavity; two ends of a third connecting pipe are respectively communicated with a right wall surface of the volume cavity and an air inlet pipe of the engine; and the penetrating pipe penetrates through the upper and lower walls of the moving body. In the operating process of the engine, the moving body can move left and right in the volume cavity; the pressure on the right side of the moving body is low and the moving body moves to the right side under low-speed working conditions, the first connecting pipe cannot be communicated with a second connecting pipe, the air inlet quantity of the engine is relatively increased, and the power of the engine is raised; and the pressure on the right side of the moving body is high and the moving body moves to the left side under high-speed working conditions, the first connecting pipe is communicated with the second connecting pipe, the air inlet quantity of the engine is relatively reduced, and the detonation pressure of each cylinder is reduced. The turbine exhaust device is reasonable in design, simple in structure and suitable for a turbocharging system of the engine.

Description

technical field

[0001] The invention relates to an exhaust system in the field of internal combustion engines, in particular to a turbo exhaust device with a through pipe for a supercharged engine. Background technique

[0002] With the development of modern society, people have higher and higher requirements on the power and economy of the engine. In the case of a certain displacement, the most effective way to increase the output power of the engine is to provide more fuel for combustion. It is easy to provide more fuel to the cylinder through the injector, but it is not so easy to provide the amount of air to match the increased amount of fuel at the same time; The effect is poor. When the fuel injection volume is constant and the cylinder air intake volume is large, the combustion is better, and the fuel consumption and emissions are lower. The traditional naturally aspirated engine completely relies on the vacuum formed in the cylinder to inhale air when the piston m...
