Abstract
A kind of closure of forming by two or more blades, throttle plate pin by transfer drives with identical forward reversing, in control air inflow size, form corresponding deflection angle, mixed gas rotates through water conservancy diversion, the aperture of its spin intensity and closure is inversely proportional to: aperture is more little, rotates strong more.Therefore, when closure is opened fully, do not increase under the prerequisite of intake resistance, can improve the atomizing effect when the middle or small aperture of closure greatly, thus fuel saving.
Description
The present invention relates to the closure part of gasoline engine carburetor.
The contradiction of best atomizing effect under each operating mode between very difficult maximum aeration quantity of solution of common gasoline engine carburetor and the least charging quantity.That is: when engine load was big, aeration quantity was big, and the mixed gas flow velocity is fast, and atomizing effect is good; And aeration quantity is little when medium and small load, and the mixed gas flow velocity is slow, and atomizing effect is poor.
The present invention proposes according to this contradiction, and realizes like this: common monolithic closure is divided into two or more blades, and each blade is driven by discrete throttle plate pin.Be that embodiment is illustrated with two-leaved eddy flow closure now, its structure is provided by accompanying drawing 1.
Accompanying drawing 1 is the assembling schematic representation, its main body is carburettor base (2), throttle plate pin A(3) and throttle plate pin B(4) insert and the axis hole of the pivot pin that makes an A one end and axle B one end plugs together and makes Spielpassung from the axis hole at carburettor base two ends respectively, make it to support each other.Closure blade A(1) with closure blade B(6) be fixed on throttle plate pin A and the throttle plate pin B by fixing bolt (5) respectively, owing to the thrust function throttle plate pin of closure blade is placed restrictions in carburettor base, but do not influence its rotation.
Accompanying drawing 2 is the working principle schematic representation.When the eddy flow closure is worked, driving each by continuous action device reverses with identical forward (clockwise or counterclockwise), its scope is arbitrarily angled between zero degree to nine ten degree, at this moment the cross-shaped unlatching of closure, form corresponding deflection angle in control air inflow size, mixed gas rotates through closure blade water conservancy diversion.Throttle opening hour deflection angle is big, and the mixed gas rotation is strong; When throttle opening was big, deflection angle was little, and a little less than the mixed gas rotation: deflection angle disappears when closure is opened fully, and mixed gas directly flows through.
Compare with former closure, when the eddy flow closure is opened fully, do not increase intake resistance, thereby can not lose engine power, but improved the atomizing of motor when middle or small load to a great extent, thereby improve burning, fuel saving.Work under middle or small load because motor is many usually, therefore, the present invention can play a role to the full extent.
The present invention is simple in structure, and its principle is applicable to various gasoline engine. The adjustment that the works such as air entry of associated linkage, idling and transition system, vacuum firing device need be adapted when putting into practice is so that co-ordination.
