Description
Technical field
What the present invention relates to is a kind of turbo charge system of field of internal combustion engine, particularly a kind of exhaust pipe volume self-adapting type turbo charge system.
Background technique
Along with the development of society and the raising of environmental requirement, the engine booster The Application of Technology more and more widely, in powerful motor mostly adopt turbocharging technology, to improve power and to reduce fuel consumption rate.Two kinds of basic patterns of turbo charge system are constant pressure charging system and impulse pressure charging system.Constant pressure charging system; The shared outlet pipe that volume is bigger of each cylinder, exhaust piping is relatively simple for structure, and it is constant that the outlet pipe internal pressure keeps basically; The pressure size is only relevant with the load and the rotating speed of motor, and the pressurization system that different cylinders are counted diesel engine can be designed for uniformity.Constant pressure charging system is when high-speed working condition, and pumping loss is less, and turbine efficiency is higher, and performance is more excellent; But when the low speed operating mode, can not make full use of the exhaust pulses energy.Impulse pressure charging system, according to each cylinder firing order, two cylinders or three cylinders that exhaust is not disturbed are connected with same outlet pipe, and the exhaust piping caliber is less, and the exhaust pulses energy can make full use of, low speed operating mode and instantaneous conditions better performances; But when high-speed working condition, pumping loss is bigger.This shows, if a waste pipe volume can change along with the conversion of operating mode, make exhaust pipe volume become big during high-speed working condition, during the low speed operating mode exhaust pipe volume is diminished, this is comparatively desirable.
Retrieval through to the existing technology document is found; Chinese patent ZL200410050996.; Patent name: the variable modular pulse converter supercharging device of a kind of turbo-charged diesel; This patented technology provides a kind of device of exhaust pipe volume continuous variable, can take into account the high and low rotating speed operating mode of motor preferably; But the variation of its exhaust pipe volume is to realize through moving up and down of movement rod, and this just needs to increase the special control mechanism of a cover and controls moving of movement rod, thus the more complicated that the pressurization system structure is become.
Summary of the invention
The present invention is directed to the deficiency of above-mentioned existing technology; A kind of exhaust pipe volume self-adapting type turbo charge system is provided, has made its exhaust pipe volume can self-control, taken into account the high and low rotating speed operating mode of motor preferably; And simple in structure, do not need special control mechanism.
The present invention realizes through following technological scheme; The present invention includes: first cylinder, second cylinder, the 3rd cylinder, four-cylinder, first exhaust branch pipe, second exhaust branch pipe, the 3rd exhaust branch pipe, the 4th exhaust branch pipe, outlet pipe, turbine, connecting tube, baffle rings, shifting board, elastic member, connecting tube sidewall and connecting tube rear wall; First cylinder, second cylinder, the 3rd cylinder, four-cylinder are connected with outlet pipe through first exhaust branch pipe, second exhaust branch pipe, the 3rd exhaust branch pipe, the 4th exhaust branch pipe respectively; The outlet of outlet pipe is connected with the inlet of turbine; The connecting tube sidewall is fixedly connected with the connecting tube rear wall; The opening end of connecting tube is connected with the afterbody of outlet pipe; Baffle rings is installed in the connecting tube Inner Front End and is fixedly connected with the connecting tube sidewall, and shifting board is installed in the connecting tube and is between baffle rings and the connecting tube rear wall, and shifting board is connected with the connecting tube rear wall through elastic member; Connecting tube is the uniform section pipe, and shifting board contacts with the inner wall sealing of connecting tube.
Said connecting tube is a pipe, and said baffle rings is an annulus, and said shifting board is a plectane.
Said elastic member is a spring, the axis of said elastic member and the dead in line of said connecting tube.
In working procedure of the present invention, shifting board can move forward and backward in connecting tube; In order to prevent that thereby shifting board from getting into the exhaust that outlet pipe influences four-cylinder, installed baffle rings in connecting tube.When motor was in the low speed operating mode, exhaust pressure was lower in the outlet pipe, and shifting board moves towards the direction near baffle rings, and the volume of outlet pipe is less relatively, and pulse energy can make full use of, and engine charge pressure is higher, and motor complete machine performance is more excellent; When motor was in high-speed working condition, exhaust pressure was higher in the outlet pipe, and shifting board moves towards the direction away from baffle rings, and the volume of outlet pipe is relatively large, and pumping loss is less, and motor complete machine performance is more excellent.
Compared with prior art; The present invention has following beneficial effect: the present invention is reasonable in design; Simple in structure; Be applicable to that turbine inlet has the turbo charge system of and turbine side, can take into account the high and low rotating speed operating mode of motor, can make pressurization system not need special exhaust pipe volume control mechanism again.
