Abstract
The invention provides a turbocharging system with a self-regulated-volume exhaust pipe and belongs to the technical field of internal combustion engines. The turbocharging system comprises a cylinder, an exhaust pipe, a turbine, a connecting pipe, a casing pipe, a baffle ring and an elastic component, wherein one opening end of the connecting pipe is connected with the tail of the exhaust pipe, the other opening end of the connecting pipe stretches into the opening end of the casing pipe, the baffle ring is arranged in the connecting pipe, and the elastic component is arranged between the baffle ring and the back wall of the casing pipe. When the engine is in a low-speed working condition, the back wall of the casing pipe can move toward the direction close to the baffle ring, thus the exhaust pipe volume can be relatively smaller, the pulse energy can be fully utilized, the inlet pressure of the engine can be higher and the overall performance of the engine can be better; when the engine is in a high-speed working condition, the back wall of the casing pipe can move toward the direction far from the baffle ring, thus the exhaust pipe volume can be relatively larger, the pumping loss can be less and the overall performance of the engine can be better. The turbocharging system with the self-regulated-volume exhaust pipe provided by the invention is reasonable in design and simple in structure and can be applied to the turbocharging system which has only one turbine inlet and is laterally provided with the turbine.

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-interacting 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, sleeve pipe, first elastic member, second elastic member, sleeve pipe sidewall and sleeve pipe 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 sleeve pipe sidewall is fixedly connected with the sleeve pipe rear wall; One opening end of connecting tube is connected with the afterbody of outlet pipe; Another opening end of connecting tube stretches into the opening end of sleeve pipe, and baffle rings is installed in the interior rear end of connecting tube and is fixedly connected with the wall of connecting tube, and baffle rings is connected with the sleeve pipe rear wall through first elastic member, second elastic member respectively; Connecting tube and sleeve pipe are the uniform section pipe, and the outer wall of connecting tube contacts with the internal face sealing of sleeve pipe sidewall.
Said connecting tube and sleeve pipe are pipe, and said baffle rings is an annulus.
Said first elastic member and second elastic member are spring, the axis of said first elastic member and second elastic member all with the parallel axes of said connecting tube.
In working procedure of the present invention, the sleeve pipe sidewall can move forward and backward outside connecting tube; For first elastic member and second elastic member are installed, baffle rings has been installed in connecting tube.When motor was in the low speed operating mode, exhaust pressure was lower in the outlet pipe, and the sleeve pipe rear wall 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 the sleeve pipe rear wall 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.
