Abstract

The utility model relates to a secondary atomizing device for the carburetor of a gasoline engine, belonging to the technical field of an atomizing device. The utility model is composed of the upper body of an engine inlet branch pipe (1), a secondary throat tube (2), a carburetor joint bolt (3), a heat insulating pad (4), a connecting flange (5), a centripetal arc bulge (7) arranged on the inner wall of the secondary throat tube, a gasket (6), a spring steel wire retainer ring (8) for shafts and the lower part of carburetor (9). The utility model has the advantages of sufficient oil gas atomization, uniform mix, complete combustion and favorable heat utilizing effect; the fuel can be saved by 5-13%, and the exhaust of the harmful gas can be reduced.

Description

A kind of petrol engine carburetor secondary-atomizing device

The utility model is an especially automotive gasoline engine Carburetor secondary-atomizing device of a kind of petrol engine, belongs to the atomising device technical field.

In the prior art, petrol engine is that devices such as the small venturi by Carburetor, middle trunnion, big trunnion carry out to the atomizing of gasoline, but owing to be subjected to the restriction of atomization space or the defective on the atomising device self structure, be easy to generate insufficient, the elaioleucite skewness of atomizing, cause the atomization gas incomplete combustion, the waste gas that gives off becomes black smoke, has not only reduced the effective utilization to gasoline heat energy, and the waste gas that gives off to external world environment caused substantial pollution.

The purpose of this utility model be provide for fear of above-mentioned the deficiencies in the prior art part the atomizing of a kind of Carburetor fully, air with elaioleucite mixes, the atomization gas burning fully, can improve the fuel oil thermal utilization effect significantly, reduce the petrol engine carburetor secondary-atomizing device that harmful exhaust discharges greatly.

The purpose of this utility model can reach by following measure:

A secondary trunnion is installed in the central axial bore of connecting flange; Connecting flange is connected as one by Carburetor attachment bolt and throttle body and air intake branch of the engine upper body; The outer wall of secondary trunnion becomes cylindric, and inwall has a disposition circular arc shaped projection, and axle Spring Steel Wire ring washer is installed in the groove of neck, and the lower body of its suitable for reading and Carburetor is closely driven and connect, and the outer wall of its end opening and air intake branch of the engine inwall are for being slidingly connected; On the bottom layer of connecting flange and last aspect, be lined with mat insulation and liner respectively.

It is 7 °-10 ° that secondary trunnion outer wall vertical line and inwall oblique line elongation line intersect formed angle, its best angle be 8 ° 30 '.The length of secondary trunnion is 40-50mm, and its external diameter should adapt with the internal diameter of all kinds air intake branch of the engine.

To do the drawing explanation below:

Accompanying drawing 1 is the longitudinal sectional view of secondary trunnion (2).

Accompanying drawing 2 is the front view of connecting flange (5).

Accompanying drawing 3 is that secondary trunnion (2) outer wall vertical line and inwall oblique line elongation line intersect the angle (10) that forms.

The utility model provides preferred forms with accompanying drawings:

Shown in accompanying drawing 1,2: a secondary trunnion (2) is installed in the central axial bore of connecting flange (5).As shown in Figure 1: connecting flange (5) is connected as one by Carburetor attachment bolt (3) and Carburetor (9) lower body and air intake branch of the engine (1) upper body; The outer wall of secondary trunnion (2) becomes cylindric, external diameter is 46mm, length is 45mm, inwall has a centrality circular arc shaped projection (7), the radius of arc smooth transition is R8mm, and its neck has an annular groove, and depth of groove is 2mm, axle Spring Steel Wire ring washer (8) is installed in the groove, and axle is Φ 2mm with the diameter of Spring Steel Wire ring washer (8); Be lined with asbestos mat insulation (4) and paper liner (6) on the bottom layer of connecting flange (5) and the last aspect respectively.As shown in Figure 3: secondary trunnion (2) outer wall vertical line and inwall oblique line elongation line intersect formed angle (10) angle be 8 ° 30 '.

Be applicable to that by the utility model of above data manufacturing the Carburetor of models such as Dongfeng brand automobile EQH102 type, EQH103 type, EQH105 type installs and uses.

The utility model with the advantage that has technology to compare to have be:

(1) the oil gas atomizing fully mixes. The internal diameter of secondary trunnion (2) is from large to small, again by little Become big, the internal diameter of different specification size when air-flow by the time can make it to produce eddy current, can atomize for the first time Oil gas fully atomize again, and mix.

(2) burning is complete, and thermal utilization effect is good. Gas through fully atomizing and mixing is when entering combustion Burn indoor just can completing combustion, improve its heat energy utilization effect. Factually border test: the utility model is installed Automobile carburetor under identical traffic condition, can save oil firing 5-13%, have significant economic benefit.

(3) greatly reduce the discharging of pernicious gas, be conducive to the protection of external environment. Because secondary-atomizing Gas combustion is complete, and do not have in the waste gas of discharging or seldom contain not burned most oil, The waste gas of motor vehicle emission does not become black smoke, and floss hole does not become black, forms rufous, can greatly alleviate automobile The waste gas of the discharging to external world public hazards that cause of environment pollutes, and has significant social benefit.
