Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by detailed description of the invention.
nullRefer to shown in Fig. 1 to Fig. 3，In the present embodiment，A kind of engine variable vortex air intake manifold structure includes inlet manifold 1，The side that described inlet manifold 1 is provided with air intake duct 10 is provided with inlet manifold cylinder cap flange 2，The thickness of described inlet manifold cylinder cap flange 2 is more than the thickness of described inlet manifold 1，Described air intake duct 10 can use any one of tangential air flue or helical intake，The corresponding each independent air intake duct 10 in the lower surface of described inlet manifold cylinder cap flange 2 is all machined with axis hole 3，Rotating shaft 4 it is vertically arranged with rotationally in described axis hole 3，And axially without play，Inlet manifold cylinder cap flange 2 and this end face are stretched out for semicircle in one end of described rotating shaft 4，All rotating shafts 4 are stretched out one end of inlet manifold cylinder cap flange 2 and are connected by linkage part，And it is provided with laminating plane in described rotating shaft 1，It is fixed with eddy current valve block 5 in described laminating plane，Gap is there is between described eddy current valve block 5 and the inwall of each air intake duct 10，So that eddy current valve block 5 also has air-flow to pass through when closed position，Ensure that gas fully burns in entering cylinder.
Described linkage part includes eddy current drive 6, drive rod 7, connecting rod 8 and drives plate 9, described eddy current drive 6 is connected with described drive rod 7, described drive rod 7 is connected with described connecting rod 8, described driving plate 9 is articulated with in described connecting rod 8, and the corresponding each rotating shaft 4 of installation site of described driving plate 9 is arranged, described rotating shaft 4 is stretched out one end of inlet manifold cylinder cap flange 2 and is connected to drive on plate 9, and described eddy current drive 6 is driven by motor, Engine ECU is controlled.
Referring to shown in Fig. 4, Fig. 4 is the eddy current valve block closed mode figure of the engine variable vortex air intake manifold structure that this utility model detailed description of the invention 1 provides.Now eddy current valve block 5 completely closes, although have space between eddy current valve block 5 and air intake duct 10, but almost all air inlet is all entered cylinder by right side air flue.Because two, left and right air inlet is symmetrically distributed in the side of burning ceiling, it is that air inlet will deflect in cylinder arm friction in cylinder when right side air flue charge flow rate is far longer than left side air flue, forms the eddy current around cylinder centerline.When engine cold-start, Smaller load run, eddy current valve block 5 is closed, air inlet sectional area reduces, air velocity is accelerated, in the case of charge flow rate coefficient is less, the eddy motion formed in cylinder can greatly promote the mixing of air and fuel oil, improves efficiency of combustion, thus effectively reduces fuel oil consumption and emission level.
Referring to shown in Fig. 5, Fig. 5 is the eddy current valve block opening figure of the engine variable vortex air intake manifold structure that this utility model detailed description of the invention 1 provides.Now rotating shaft 4 rotates under the drive of eddy current drive 6 counterclockwise, and eddy current valve block 5 is rotated to open position by closed position accordingly, inlet manifold 1 enter cylinder cap air intake duct 10 two bursts of air-flow independences from left and right air inlet flow into cylinder.Within the engine at a high speed, middle high load capacity time, for reaching bigger output, it is desirable to have sufficient air inflow, now open eddy current valve block 5, increase air inlet area, improve charge flow rate coefficient, make electromotor have preferably and export response.
Experiment proves, above-mentioned engine variable vortex air intake manifold structure can solve the problem that the problems such as oil consumption is high, discharge is poor when engine cold-start, Smaller load run, performance under electromotor high speed operating mode will not be adversely affected simultaneously, also help the output response under each operating mode of electromotor.This utility model can effectively realize opening and closing the function of side air intake duct, and by ECU, this eddy current valve block is carried out step-less adjustment, the coupling each work condition state of electromotor, the effect of eddy current in low speed Smaller load state generation cylinder, high speed, middle high load capacity can ensure the Proper Match of engine intake airflow coefficient and swirl ratio, improve the burning under each operating mode of electromotor and emission effect.
Above example simply elaborates ultimate principle of the present utility model and characteristic; this utility model is not limited by above-mentioned example; on the premise of without departing from this utility model spirit and scope; this utility model also has various change and change, in the range of these changes and change both fall within claimed this utility model.This utility model claims scope and is defined by appending claims and equivalent thereof.
