Abstract

A turbocharging system with two rotating plates in front of a turbine inlet belongs to the technical field of internal combustion engines and comprises a cylinder, an exhaust tube, a connecting tube, a turbine, a capacity cavity, the rotating plates, a rotating shaft and an elastic component. An opening end of the capacity cavity is connected with the upper wall surface of the connecting tube, the rotating shaft is mounted between a front wall surface and a rear wall surface of the connecting tube, both the first rotating plate and the second rotating plate are integrally fixedly connected with the rotating shaft, and the second rotating plate is connected with the lower wall surface of the connecting tube via the elastic component. When an engine is in a high-speed working condition, both the two rotating plates rotate clockwise, the area of a throat of the connecting tube is large, so that pumping loss is low, and performances of the total engine are excellent; and when the engine is in a low-speed working condition, both the two rotating plates rotate anticlockwise, the area of the throat of the connecting tube is small, available energy in front of the turbine is sufficient, air inlet pressure of the engine is high, and the performances of the integral engine are excellent. The turbocharging system is reasonable in design and simple in structure. The invention is applicable to a turbocharging system with a side-mounted turbine at a turbine inlet.

Description

technical field

[0001] The invention relates to a turbocharging system in the field of internal combustion engines, in particular to a turbocharging system with two rotating plates in front of a turbine inlet. 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 sup...
