Description
Technical field
The invention belongs to technical field of automobile components, be specifically related to a kind of two compressed air induction system.
Background technique
Along with the development of automobile product, the requirement of user to power performance and Economy is more and more higher, existing motor car engine is because of the difference of behaviour in service and condition, all cannot play the performance of its best, the use of turbosupercharger is increasingly extensive, and turbosupercharger mainly relies on the waste gas of exhaust to promote turbine rotation thus makes air inlet side suck more air to reach the effect maximizing acting.But just to strike sparks or in slow-revving situation, the extraction flow of motor promotes impeller not, the circulation power of automobile exhaust gas at automobile, be not enough to the running driving turbine; And ought suddenly step on the throttle, at this time extraction flow has become greatly instantaneously, but the impeller even do not rotated that originally slowly runs is not promoted due to inertia at once, and after waiting until that engine speed improves, when exhaust dynamics is larger, turbine just can start; So turbosupercharger can be delayed a period of time and just enter normal working state, this generates supercharging hysteresis phenomenon, the power character that impact is driven.
Summary of the invention
The object of this invention is to provide a kind of two compressed air induction system, by cooperatively interacting of Electron pressurizing unit and turbosupercharger, the hysteresis phenomenon even eliminating turbosupercharger can be extenuated, the Economy of raising fuel oil.
To achieve these goals, the invention provides following technological scheme:
A kind of two compressed air induction system, comprise air-strainer, Electron pressurizing unit and turbosupercharger, described air-strainer is provided with the first outlet and the second outlet, described first outlet is connected with described turbosupercharger by bypass valve, described second outlet is connected with described Electron pressurizing unit, and described turbosupercharger is connected with motor respectively with described Electron pressurizing unit.
Preferably, when the rotating speed of described motor reaches predefined value, close described Electron pressurizing unit.
Preferably, the car body controller of the open and close controlling described Electron pressurizing unit is also comprised.
Preferably, there is steam outlet pipe the air outlet of described air-strainer by Flange joint, and the other end of described steam outlet pipe is provided with the first outlet and described second and exports.
Preferably, described first outlet and described second exports and is equipped with bellows.
Preferably, the ripple of described bellows is at least five roads.
Preferably, seal ring is provided with between described air outlet and described flange.
Beneficial effect of the present invention is:
The present invention is by increasing Electron pressurizing unit and bypass valve, just to strike sparks or in slow-revving situation at automobile, air input of engine by air is less, because stream pressure is not enough to push bypass valve open, bypass valve cuts out, turbosupercharger does not work, now, Electron pressurizing unit works, with Quick high-engine rotating speed, when engine speed brings up to certain value, waste gas after engine combustion can promote turbosupercharger and carry out work, simultaneously because air input of engine by air increases, suction pressure pushes bypass valve open, air-flow directly enters turbosupercharger by bypass valve, effectively can get involved work, to provide larger power.By this pair of supercharger systems, because the motor response of Electron pressurizing unit is very fast, can effectively extenuates the hysteresis phenomenon even eliminating turbosupercharger, improve the power character handled, increase the Economy of fuel oil.

Embodiment
In order to make object of the present invention, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Please refer to Fig. 1-Fig. 2, in a kind of embodiment, provided by the present invention pair of compressed air induction system, comprise air-strainer 1, Electron pressurizing unit 3 and turbosupercharger 5, air-strainer is provided with the first outlet and the second outlet, first outlet is connected with turbosupercharger 5 by bypass valve 4, and the second outlet is connected with Electron pressurizing unit 3, and turbosupercharger 8 is connected with motor respectively with Electron pressurizing unit 3.
Above-described embodiment is by increasing Electron pressurizing unit 3 and bypass valve 4, just to strike sparks or in slow-revving situation at automobile, air input of engine by air is less, because stream pressure is not enough to push bypass valve 4 open, bypass valve 4 cuts out, turbosupercharger 5 does not work, now, Electron pressurizing unit 3 works, with Quick high-engine rotating speed, when engine speed brings up to certain value, waste gas after engine combustion can promote turbosupercharger 5 and carry out work, simultaneously because air input of engine by air increases, suction pressure pushes bypass valve 4 open, air-flow directly enters turbosupercharger 5 by bypass valve 4, effectively can get involved work, to provide larger power.By this pair of supercharger systems, because the motor response of electronics supercharging 3 is very fast, effectively can extenuates the hysteresis phenomenon even eliminating turbosupercharger 5, improve the power character handled, increase the Economy of fuel oil.
Preferably, when the rotating speed of motor reaches predefined value, close Electron pressurizing unit 3.Because Electron pressurizing unit 3 needs to consume electric energy, and long-term high rotating speed can cause the problems such as heat radiation, and this setting can either save the energy, can protect Electron pressurizing unit 3 again.
Usual predetermined value elects 1500 rpms as.
Certainly when the rotating speed of motor reaches predefined value, Electron pressurizing unit 3 also can not be closed, i.e. Electron pressurizing unit 3 and turbosupercharger hybrid working.
Above-described embodiment also comprises the controller of the open and close controlling Electron pressurizing unit 3.Directly control Electron pressurizing unit 3 by controller, the system coordination of car load can be facilitated, improve control efficiency.
Two compressed air induction system also comprises the car body controller of the open and close controlling Electron pressurizing unit 3, and namely controller is car body controller.By car body controller, the quantity of the controller of vehicle can be reduced, improve the efficiency controlled.
There is steam outlet pipe 2 air outlet of air-strainer 1 by Flange joint, and the other end of steam outlet pipe 2 is provided with the first outlet and second and exports.By Flange joint, conveniently can manufacture processing and increase the reliability be connected.The air outlet of air-strainer also directly can be connected with the first outlet and second and export.
First outlet and second exports and is equipped with bellows.By arranging bellows, can absorption portion noise, to extenuate the vibration from motor.First outlet and second exports and also can be straight tube.
The ripple of bellows is at least five roads.This quantity can either play the effect absorbing noise, can not increase again too large processing burden.The ripple of bellows can be together, twice, six roads or more.
First outlet is usually shaping by injecting glue, selects ECO material, and the second outlet, usually by blow moulding and forming, selects TPE+PP material.Conveniently process and improve its working life.
Seal ring is provided with between air outlet and flange.By increasing seal ring, the sealing of whole air-flow can be increased, ensureing the power of motor.O type circle selected by usual seal ring, convenient manufacture and processing.Also can be square or other structure.
Although the present invention is described in conjunction with above embodiment, but the present invention is not limited to above-described embodiment, and only by the restriction of claim, those of ordinary skill in the art can easily modify to it and change, but do not leave essential idea of the present invention and scope.
