Technical field

The utility model is related to engine art, more particularly to a kind of engine with supercharger burner and system.

Background technology

Constantly increase with the increasingly demand of people, the load more and more higher of engine with supercharger is wanted to engine with supercharger Also more and more higher is sought, but for engine with supercharger, the one of consideration is needed when Tumble intensity is air flue and Combustion chamber design Individual key factor.In existing conventional design, the raising of Tumble intensity certainly will cause the weakening of discharge coefficient, it will usually One gear gas face of admission line exit design, its structure is as shown in figure 1, prior art is typically the 180 of the admission line back side Design gear gas face 12 ', higher in some Tumble intensities in the range of degree, and compression ratio is than in the case of larger, in engine with supercharger Combustion chamber easily there is vortex parallel to top land, the intensity of the vortex is bigger, and engine with supercharger is in combustion More easily there is pinking.Simultaneously because the engine with supercharger of prior art is simply set in the range of the 180 degree at the admission line back side Meter gear gas face, can form a larger step, such as Fig. 3 institutes with the junction 16 ' in the non-gear gas face of other 180 degree of admission line Show, arranged because the 90 degree of gear gas faces of admission line in the inner part have largely weakened to be flowed to through spark plug by admission line The air-flow of feed channel, the presence of the step further hinders the air-flow for flowing to discharge duct through spark plug by admission line, So that the strength of vortex parallel to top land is more powerful, further strengthening engine with supercharger, pinking is general in combustion Rate, causes high risks, it is impossible to meet demand.

Utility model content

The purpose of this utility model is that overcoming the gear gas face of prior art to design easily causes engine with supercharger pinking It is not enough that there is provided a kind of engine with supercharger burner and system.

The technical solution of the utility model, which provides a kind of engine with supercharger burner, includes admission line, the air inlet pipe The outlet in road is provided with gear gas face, and the gear gas face is arranged on the lower half of the outlet of the admission line, and the gear gas face connects The height of the first half of the nearly outlet is less than the height of the gear first half of the gas face away from the outlet.

Further, the height in the gear gas face according to the first half away from the outlet to the upper half close to the outlet Gradually successively decrease in the direction in portion.

Further, the gear first half of the gas face away from the outlet is highly consistent.

Further, the engine with supercharger burner also includes the seat ring being connected with the admission line, the seat Circle is connected with the gear gas face, and the gear gas face is fixed on the admission line by the seat ring.

Further, the admission line is connected with the seat ring interference, and the seat ring is connected with the gear gas face interference.

Further, the gear gas face is integrally formed.

Further, the material in the gear gas face is aluminium alloy.

The utility model also provides a kind of engine with supercharger combustion system, including increases described in combustion chamber and any of the above-described Hydraulic motor burner, the combustion chamber is connected with the gear gas face.

Further, the admission line is at least two.

After adopting the above technical scheme, having the advantages that：By the way that the lower half of the outlet of admission line is set Gas face is kept off, gear gas face is less than the height of the first half of the gear gas face away from outlet close to the height of the first half of outlet, by this The particular design in gear gas face makes, close to the excessive of inside region smooth-going, to change air-flow of the charge air flow along inner side to exhaust side strong Degree, so as to reduce the strength of vortex parallel to top land, prevents engine with supercharger from occurring pinking during burning, improves The efficiency of combustion of engine with supercharger, increases the life-span of engine with supercharger.
