Abstract
A turbocharger system with a movable body arranged in an air exhaust pipe belongs to the technical field of combustion motor and comprises an air cylinder, the air exhaust pipe, a turbine, a blocking plate, the movable body and an elastic component. The movable body is fixedly and integrally connected with the rear wall of the movable body, the movable body and the rear wall of the movable body are both installed in the air exhaust pipe, and the rear wall of the movable body is connected with the rear wall of the air exhaust through the elastic component. When a motor is on the low speed work condition, the movable body and the rear wall of the movable move towards the direction far away from the rear wall of the air exhaust pipe, the volume of exhausted air in the air exhaust pipe is relatively small, pulse energy can be fully used, air inlet pressure of the motor is high, and the whole machine performance of the motor is excellent. When the motor is on the high speed work condition, the movable body and the rear wall of the movable move towards the direction close to the rear wall of the air exhaust pipe, the volume of exhausted air in the air exhaust pipe is relatively large, pumping loss is small, and the whole machine performance of the motor is excellent. The turbocharger system is reasonable in design, simple in structure and suitable for turbine systems with one turbine inlet and a laterally arranged turbine.
Description
Technical field
What the present invention relates to is a kind of turbo charge system of field of internal combustion engine, and the turbo charge system of moving body is housed in particularly a kind of outlet pipe.
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 the shared volume of exhaust can change along with the conversion of operating mode in the waste pipe; Make the shared volume of the interior exhaust of outlet pipe become big during high-speed working condition, the interior shared volume of exhaust of outlet pipe 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 the device of the shared volume continuous variable of exhaust in a kind of outlet pipe, can take into account the high and low rotating speed operating mode of motor preferably; But the variation of exhaust institute volume is to realize through moving up and down of movement rod in its outlet pipe, 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; The turbo charge system that moving body is housed in a kind of outlet pipe is provided, has made in its outlet pipe the shared volume of exhaust 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, turbine, outlet pipe sidewall, outlet pipe rear wall, baffle plate, moving body, moving body rear wall and 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 turbine; Outlet pipe sidewall and outlet pipe rear wall fix as one, and outlet pipe is the uniform section pipe, and baffle plate is installed in the outlet pipe and with the outlet pipe sidewall and fixes as one; Moving body and moving body rear wall fix as one; Moving body and moving body rear wall are installed in the outlet pipe, and moving body all contacts with the sealing of outlet pipe sidewall with the moving body rear wall, and the moving body rear wall is connected with the outlet pipe rear wall through elastic member.
Said outlet pipe is a pipe, and said elastic member is a spring, the axis of said elastic member and the dead in line of said outlet pipe.
In working procedure of the present invention, moving body and moving body rear wall can move forward and backward in outlet pipe together.When motor is in the low speed operating mode; Exhaust pressure is lower in the outlet pipe; Moving body and moving body rear wall move towards the direction away from the outlet pipe rear wall together, and the shared volume of exhaust is less relatively in the outlet pipe, and pulse energy can make full use of; 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 moving body and moving body rear wall move towards the direction near the outlet pipe rear wall together, and the shared volume of exhaust is relatively large in the outlet pipe, 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, and is simple in structure, is 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 control mechanism again.
