Turbocharger system with movable body arranged in air exhaust pipe

Abstract

A turbocharger system with a movable body arranged in an air exhaust pipe belongs to the technical field of combustion motor and comprises an air cylinder, the air exhaust pipe, a turbine, a blocking plate, the movable body and an elastic component. The movable body is fixedly and integrally connected with the rear wall of the movable body, the movable body and the rear wall of the movable body are both installed in the air exhaust pipe, and the rear wall of the movable body is connected with the rear wall of the air exhaust through the elastic component. When a motor is on the low speed work condition, the movable body and the rear wall of the movable move towards the direction far away from the rear wall of the air exhaust pipe, the volume of exhausted air in the air exhaust pipe is relatively small, pulse energy can be fully used, air inlet pressure of the motor is high, and the whole machine performance of the motor is excellent. When the motor is on the high speed work condition, the movable body and the rear wall of the movable move towards the direction close to the rear wall of the air exhaust pipe, the volume of exhausted air in the air exhaust pipe is relatively large, pumping loss is small, and the whole machine performance of the motor is excellent. The turbocharger system is reasonable in design, simple in structure and suitable for turbine systems with one turbine inlet and a laterally arranged turbine.

Description

technical field [0001] The invention relates to a turbocharging system in the field of internal combustion engines, in particular to a turbocharging system in which a moving body is arranged in an exhaust pipe. 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 su...

Problems solved by technology

[0003] After searching the existing technical documents, it was found that Chinese Patent No. ZL200410050996., patent name: a variable modular pulse conversion supercharging device for a turbocharged diesel engine. The continuously variable volume device can better take into account the high and low speed conditions of the engine; however, the volume change of the exhaust gas in the exhaust pipe is realized by moving the moving rod up and down, which requires an additional set of special controls mechanism to control the movement of the moving rod, which makes the structure of the booster system more complicated
