Abstract

The invention relates to a peripheral gas path system of a marine engine. The peripheral gas path system of the marine engine comprises gas compressors, a gas inlet pipe, an engine, a gas exhaust pipe, turbines, a volume chamber, connecting pipes, a movable body, a spring and a through pipe, wherein the movable body is installed in the volume chamber and is in hermetical contact with the inner wall surface of the volume chamber, the through pipe penetrates through the upper wall surface and the lower wall surface of the movable body, and the right wall surface of the movable body is connected with the right wall surface of the volume chamber through the spring. When the engine is under a high-speed working condition, the movable body moves leftwards, a first gas compressor, a second gas compressor, a first turbine and a second turbine work at the same time, the pumping loss of the engine is smaller and the performance of the entire engine is better; and when the engine is under a low-speed working condition, the movable body moves rightwards, only the first gas compressor and the first turbine work, the pulse energy is fully utilized, the gas inlet pressure of the engine is higher and the performance of the entire engine is better. The peripheral gas path system of the marine engine has the advantages of reasonable design and simple structure, and is suitable for a turbine supercharging system with double turbines and double gas compressors.

Description

technical field [0001] The invention relates to a turbocharging system in the field of internal combustion engines, in particular to a peripheral air circuit system of a marine engine. 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 a large-volume exhaust pipe, the structure of the exhaust pipe system is relatively simple, the equivalent flow area of ​​the turbine is relatively large, the pressure in the exhaust pipe is basically kept constant, and the pressure is only related to the load of the engine It is relat...
