Turbocharging system with synchronous rotating mechanism

Abstract

The invention relates to the technical field of mechanical design, in particular to a turbocharging system with a synchronous rotating mechanism. The turbocharging system comprises an accommodating cavity, an elastic member, a rotor, a partition, rotary shafts, rotary plates and a chain. The longitudinal section of the accommodating cavity is circular. The longitudinal section of each of a fixed member and the rotor is arc shaped. An exhaust pipe is a uniform section round tube. A first pass pipe and a second pass pipe are both disposed inside the fixed member. The upper wall of the second pass pipe is connected with the partition through the elastic member. When an exhaust branch pipe of an engine bears high inner pressure, the rotor drives the rotary plates to rotate anticlockwise, necking rate of the exhaust branch pipe is high, and pumping loss of the engine is low; when the exhaust branch pipe of the engine bears low inner pressure, the rotor drives the rotary plates to rotate clockwise, necking rate of the exhaust branch pipe is low, pulse energy can be fully utilized, and front available energy of a turbine is abundant. The turbocharging system is reasonable in design and simple in structure and is applicable as turbocharging system having a side turbine and a turbine inlet.

Description

technical field [0001] The invention relates to a turbocharging system in the technical field of mechanical design, in particular to a turbocharging system with a synchronous rotating mechanism. 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 medium and high-power engines adopt turbocharging technology to improve power and reduce fuel consumption. The two basic types of turbocharging systems are constant pressure boosting systems and pulse boosting systems. In the constant pressure supercharging system, each cylinder shares an exhaust pipe with a large volume. The structure of the exhaust pipe system is relatively simple, and the pressure in the exhaust pipe is basically kept constant. The pressure is only related to the load and speed of the engine. The supercharging system of the diesel engine can be de...
