Abstract

The invention discloses a turbocharging system with continuously adjustable volume of an exhaust pipe, belonging to the technical field of internal combustion engines. The turbocharging system comprises a cylinder, the exhaust pipe, a turbine, a volume cavity, a sleeve body, a baffle and an elastic part, wherein an opened end of the volume cavity is connected with the side wall surface of the exhaust pipe, and the other opened end of the volume cavity extends into an opened end of the sleeve body; the baffle is arranged in the volume cavity; the elastic part is arranged between the baffle andthe rear wall of the sleeve body; when an engine is in a low-speed working condition, the rear wall of the sleeve body moves towards the direction close to the baffle, the volume of the exhaust pipe is relatively smaller, the pulse energy can be fully utilized, the gas inlet pressure of the engine is higher and the overall performance of the engine is better; and when the engine is in a high-speed working condition, the rear wall of the sleeve body moves towards the direction far away from the baffle, the volume of the exhaust pipe is relatively larger, the pump gas loss is less, and the overall performance of the engine is better. The turbocharging system is reasonable in design and simple in structure, and one of the turbocharging system provided by the turbine is applicable to the turbine inlet.

Description

technical field [0001] The invention relates to a turbocharger system in the field of internal combustion engines, in particular to a continuously adjustable turbocharger system with an exhaust pipe volume. Background technique [0002] With the development of society and the improvement of environmental protection requirements, the application of engine supercharging technology is becoming more and more extensive. Most of the engines with medium and high power adopt turbocharging technology to improve power and reduce fuel consumption. The two basic types of turbocharging systems are constant pressure supercharging system and pulse supercharging system. Constant pressure supercharging system, each cylinder shares an exhaust pipe with a large volume, the structure of the exhaust pipe system is relatively simple, the pressure in the exhaust pipe is basically kept constant, the pressure is only related to the load and speed of the engine, different cylinder numbers The superc...
