Background technology
The eddy current of engine aspirating system when discharge coefficient is the key that affects combustion system of engine performanceIndex, has conclusive impact to the quality of combustion system of engine. But, the shape of air intake duct at presentShape is by casting straight forming, is subject to the restriction of casting technique itself, and uniformity and the precision of production are difficult toControl, when discharge coefficient deviation is larger to cause the eddy current of different product of same Design of Inlet. AndIn order to obtain when discharge coefficient of different eddy current, need to develop different air intake duct shapes, thereby needDifferent air intake duct casting moulds, this has strengthened time cost and the cost of investment of engine development undoubtedly.
The information that is disclosed in this background technology part is only intended to increase the reason to general background of the present inventionSeparate, and should not be regarded as admitting or imply that in any form this information structure has been this area general technologyThe prior art that personnel are known.
Summary of the invention
The object of the present invention is to provide a kind of gas handling system of engine, form thereby overcome existing castingThe large and exploitation of the deviation of air intake duct time the time and financial cost high.
For achieving the above object, the invention provides a kind of gas handling system of engine, gas handling system comprises:Air intake duct, air intake duct is arranged in the cylinder head of engine; Inlet valve, inlet valve is movably arranged on cylinderOn the inlet valve seat ring of lid; Vortex generator, vortex generator is fixed on inlet valve, and eddy current occursDevice extends to the guide rod of inlet valve from the outer circumference surface of inlet valve head.
Preferably, in technique scheme, vortex generator is impeller, and impeller comprises body, on bodyBe provided with at least one blade.
Preferably, in technique scheme, the blade that impeller is provided with at least two kinds of shapes and varies in size.
Preferably, in technique scheme, the both sides of the junction of blade and body are equipped with knuckle.
Preferably, in technique scheme, body comprises the impeller mounting ring and the impeller disk that interfix,Impeller mounting ring is fixed on the guide rod of inlet valve, and the impeller disk is connected on the head of inlet valve.
Preferably, in technique scheme, the quantity of blade is 2-18 sheet.
Compared with prior art, the present invention has following beneficial effect:
The present invention is realized and being started by the alternative change of the structure air intake duct shape of the impeller on change inlet valveMachine eddy current is the adjustment of discharge coefficient when, without redesigning air intake duct and air intake duct casting mould, and letterChange control mode and controlled difficulty, uniformity and the precision of the gas handling system of engine are protected,Time and the financial cost of exploitation are also reduced; Reduced the requirement of engine to air intake duct function simultaneously,Make air flue shape simpler, facilitate air cylinder head structure arrange and optimize, improved the reliability of engine,Reduce casting difficulty and percent defective simultaneously; In addition, after installation impeller, strengthen the heat radiation of inlet valve head,Extend the life-span of inlet valve.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that thisThe protection domain of invention is not subject to the restriction of detailed description of the invention.
Unless separately have other clearly to represent, otherwise in whole description and claims, term " comprised "Or its conversion element or the part of stating being understood to include as " comprising " or " including " etc.,And do not get rid of other element or other part.
As shown in Figure 1, according to the gas handling system of the engine of the specific embodiment of the invention comprise air intake duct 7,Inlet valve 10 and vortex generator. Air intake duct 7 is arranged in the cylinder head of engine, inlet valve 10Be movably arranged on the inlet valve seat ring 9 of cylinder head. Vortex generator is fixed on inlet valve 10 near itThe position (as shown in Figure 3) of head 5.
As an embodiment, vortex generator is impeller 8, as shown in Figure 1. Vortex generator 8 can lead toCross integrated machine processing or different parts are processed respectively to rear assembling and obtain.
As shown in Figure 2, as an embodiment, knockdown impeller 8 is by body and at least one bladeTwo parts composition. Body comprises impeller mounting ring 1 and the impeller disk 4, and the two is fixedly connected with. As shown in Figure 3,Impeller mounting ring 1 by interference fit, be threaded and the mode such as welding is fixed on leading of inlet valve 10On bar 6, meanwhile, the impeller disk 4 is close to by the head 5 of roll-in and welding procedure and inlet valve 10, withStrengthen the heat conductivility of valve head.
Blade 2 partial fixings are on impeller mounting ring 1, and partial fixing, on the impeller disk 4, makes blade certainlyGuide rod 6 extends to the head 5 of inlet valve. Blade 2 is equipped with transition circle with the both sides of the junction of bodyAngle 3.
Preferably, the quantity of blade 2 is 1-18 sheet. Preferably, impeller 8 is provided with two and aboveWhen blade 2, have two kinds of shapes and big or small blade at least.
When this gas handling system work, inlet valve 10 impeller 8 move downward with respect to inlet valve seat ring 9,Open the air inlet of cylinder, on impeller 8, the motion of the blade 2 of each different directions makes in air intake duct 7Gas flow changes with near blade, forms eddy current and enters cylinder.
The eddy current that need to change engine is when when discharge coefficient, can by change blade 2 shape,The radius of quantity and setting angle or knuckle 3 etc. changes the concrete structure of impeller 8 to be realized.
