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 application of engine booster technology is more and more extensive, 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, each cylinder shares the outlet pipe that volume is larger, and 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 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 take full advantage 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 take full advantage of, low speed operating mode and instantaneous conditions better performances; But when high-speed working condition, pumping loss is larger.This shows, if a waste pipe volume can change along with the conversion of operating mode, make exhaust pipe volume become large during high-speed working condition, during the low speed operating mode, exhaust pipe volume is diminished, this is comparatively desirable.
Find through the retrieval to the prior art document, China Patent No. 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 preferably the high and low rotating speed operating mode of motor; But the variation of its exhaust pipe volume be by movement rod move up and down realize, this just needs to increase a special control mechanism of cover control the movement of movement rod, thus the more complicated that the pressurization system structure is become.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, 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 preferably the high and low rotating speed operating mode of motor, and simple in structure, do not need special control mechanism.
the present invention is achieved through the following technical solutions, the present invention includes: the first cylinder, the second cylinder, the 3rd cylinder, four-cylinder, the first row gas branch pipe, the second row gas 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, the first cylinder, the second cylinder, the 3rd cylinder, four-cylinder is respectively by the first row gas branch pipe, the second row gas branch pipe, the 3rd exhaust branch pipe, the 4th exhaust branch pipe is connected with outlet pipe, the outlet of outlet pipe is connected with the entrance 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 arranged on the connecting tube Inner Front End and is fixedly connected with the connecting tube sidewall, shifting board is arranged in connecting tube and is between baffle rings and connecting tube rear wall, shifting board is connected with the connecting tube rear wall by elastic member, connecting tube is the uniform section pipe, and shifting board contacts with the inner wall sealing of connecting tube.
Described connecting tube is pipe, and described baffle rings is annulus, and described shifting board is plectane.
Described elastic member is spring, the axis of described elastic member and the dead in line of described 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 entering the exhaust that outlet pipe affects four-cylinder, baffle rings has been installed in connecting tube.When motor was in the low speed operating mode, in outlet pipe, exhaust pressure was lower, and shifting board moves towards the direction near baffle rings, the volume less of outlet pipe, and pulse energy can take full advantage of, and engine charge pressure is higher, and the motor overall performance is more excellent; When motor was in high-speed working condition, in outlet pipe, exhaust pressure was higher, 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 the motor overall 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, being applicable to 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 again pressurization system not need special exhaust pipe volume control mechanism.
