Abstract
The utility model provides a kind of Vehicle Turbocharged engine inlets and engine system, and described engine inlets comprise an air flue main body, and its one end open is suction port, the other end then bifurcated and form two air outlets.Passage wherein between bifurcation, described air outlet and the air flue aditus laryngis of air outlet, is constructed to the fish-bellied type passage relatively expanded to lower recess.The Vehicle Turbocharged engine inlets that the utility model relates to, passage between bifurcation, air outlet and air flue aditus laryngis is designed to the fish-bellied type passage relatively expanded to lower recess, it can while guarantee has high Tumble and swirl, its flow coefficient of the sacrifice exceeded again.
Description
Technical field
The utility model relates to a kind of structural design of supercharged engine intake duct, and has the engine system of this intake duct.
Background technique
Typically, plug ignition gasoline supercharging engine, requires that intake duct has high Tumble intensity, is beneficial to the increase of firing chamber flame velocity of propagation, thus improves combustion efficiency.
Meanwhile, when the large load of motor height, in order to obtain satisfied power and moment of torsion, require that again intake duct has good flow coefficient.And research shows: the flow coefficient of air flue and Tumble and swirl are shifting relations.
Therefore, how for the inverse relationship between the intrinsic flow coefficient existing for intake duct and Tumble and swirl, design a novel inlet structure, it can while guarantee has high Tumble and swirl, its flow coefficient of the sacrifice exceeded again has been a difficult point of industry research and development.
Model utility content
The purpose of this utility model is to provide a kind of Vehicle Turbocharged engine inlets, and it can while guarantee has high Tumble and swirl, its flow coefficient of the sacrifice exceeded again.
To achieve these goals, the technical solution adopted in the utility model is as follows.
A kind of Vehicle Turbocharged engine inlets, it comprises an air flue main body, its one end open is suction port, the other end then bifurcated and form two air outlets, the passage wherein between bifurcation, described air outlet and the air flue aditus laryngis of air outlet is constructed to the relative fish-bellied type passage expanded to lower recess.
Further, the cross-section area of wherein said suction port is greater than two air outlet cross-section area sums.
Further, oil sprayer is provided with above wherein said air flue main body.
Further, the top of the air flue aditus laryngis near described two air outlets in wherein said air flue main body is provided with valve guide bushing.
Relative to prior art, the beneficial effects of the utility model are: the Vehicle Turbocharged engine inlets that the utility model relates to, and its position in air outlet between aditus laryngis is designed to the fish-bellied type passage relatively expanded to lower recess.Make charge air flow in this section of passage, airflow direction can be changed with the change in shape of curved surface, produce micro-upswept air-flow, and then formed under the leading role of the exhaust side wall of firing chamber and larger roll stream.
Such structure suitably increases the circulation area of air-flow path, and therefore, the momentum that can lose because direction changes air-flow produces certain effect that makes up, thus can not weaken the flow coefficient of air flue too much.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of Vehicle Turbocharged engine inlets that the utility model mode of execution relates to.
Fig. 2 is the view of another angle of the engine inlets of Vehicle Turbocharged shown in Fig. 1.
Description of reference numerals in figure is as following table.

Embodiment
Below with reference to drawings and Examples, the technological scheme of a kind of Vehicle Turbocharged engine inlets that the utility model relates to is described in further detail.
Refer to shown in Fig. 1,2, a kind of Vehicle Turbocharged engine inlets, it comprises an air flue main body 10, and its one end open is suction port 13, the other end then bifurcated and form two air outlets 12.
Wherein the cross-section area of suction port 13 is greater than the cross-section area sum of two air outlets 12, and the top near two air outlets 12 in each air flue main body 10 is respectively arranged with oil sprayer 14 and valve guide bushing 16.
Further, passage between the bifurcation, two air outlets 12 18 and the air flue aditus laryngis 15 of this air outlet 12 of air flue main body 10, its inside is constructed to the configuration of relatively expanding to lower recess, this structure of relatively expanding to lower recess, is called fish-bellied type road logical 18 visually.
The fish-bellied type passage 18 that the channels designs of intake duct of the present utility model in air outlet 12 between air flue aditus laryngis 15 becomes relatively to expand to lower recess.Charge air flow, in this section of passage, can change airflow direction with the change in shape of curved surface, produce micro-upswept air-flow, and then is formed under the leading role of the exhaust side wall of firing chamber and larger roll stream.Such structure does not suitably increase the circulation area of air-flow path, and therefore, the momentum that can lose because direction changes air-flow produces certain effect that makes up, thus can not weaken the flow coefficient of air flue too much.
Technical scope of the present utility model is not only confined to the content in above-mentioned explanation, those skilled in the art can under the prerequisite not departing from the utility model technological thought, various deformation and amendment are carried out to above-described embodiment, and these distortion and amendment all should be worked as and belonged in scope of the present utility model.
