Description
Technical field
What the present invention relates to is a kind of turbo charge system of field of internal combustion engine, the adjustable turbo charge system of particularly a kind of turbine inlet area.
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.Under the constant prerequisite of exhaust pipe volume,, also can realize taking into account of motor high and low rotating speed operating mode through changing the area of turbine inlet.When the low speed operating mode, the turbine inlet area is diminished, available energy is more before the turbine; When high-speed working condition, make the turbine inlet area become big, the motor pumping loss is less, and this also is comparatively desirable.
Retrieval through to the existing technology document is found; Chinese patent ZL201020532937.0; Patent name: the turbo charging installation of exhaust outlet variable area; This patented technology provides a kind of device of turbine inlet area continuous variable, can take into account the high and low rotating speed operating mode of motor preferably; But the variation of its turbine inlet area is the rotation through rotating handles to be realized, this just needs to increase the special control mechanism of a cover control the rotation of rotating handles, 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; Provide a kind of turbine inlet area adjustable turbo charge system, made its turbine inlet area 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, first exhaust branch pipe, second exhaust branch pipe, the 3rd exhaust branch pipe, outlet pipe, connecting tube, turbine, connecting tube upper side wall, connecting tube lower wall, connecting tube front panel, connecting tube rear sidewall, first running shaft, second running shaft, first swivel plate, second swivel plate, first elastic member and second elastic member; First cylinder, second cylinder, the 3rd cylinder are connected with outlet pipe through first exhaust branch pipe, second exhaust branch pipe, the 3rd exhaust branch pipe respectively; The outlet of outlet pipe is connected with the inlet of connecting tube; The outlet of connecting tube is connected with the inlet of turbine; Connecting tube upper side wall, connecting tube lower wall, connecting tube front panel, connecting tube rear sidewall fix as one; The cross section of connecting tube is a rectangular; The two ends of first running shaft, second running shaft are installed in connecting tube front panel and the connecting tube rear sidewall respectively, and first swivel plate and first running shaft fix as one, and second swivel plate and second running shaft fix as one; The front end of first swivel plate is connected with the connecting tube upper side wall through first elastic member, and the front end of second swivel plate is connected with the connecting tube lower wall through second elastic member.
First elastic member and second elastic member are spring.
In working procedure of the present invention, first swivel plate can be in connecting tube is the axis rotation with first running shaft, and second swivel plate can be in connecting tube is the axis rotation with second running shaft.When motor was in high-speed working condition, exhaust pressure was higher in the outlet pipe, and first swivel plate turns clockwise, and second swivel plate is rotated counterclockwise, and the throat area between two swivel plates becomes big, and the motor pumping loss is less, and motor complete machine performance is more excellent; When motor was in the low speed operating mode, exhaust pressure was lower in the outlet pipe, under the effect of first elastic member and second elastic member; First swivel plate is rotated counterclockwise; Second swivel plate turns clockwise, and the throat area between two swivel plates diminishes, and available energy is more before the turbine; Engine charge pressure is higher, 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 turbine inlet area control mechanism again.
