Abstract
The utility model relates to a secondary intake cylinder end, which comprises a cylinder end (1) which is provided with a secondary intake passage (3) communicated with an exhaust passage (2), and is characterized in that the secondary intake passage (3) is connected with a one-way valve. The cylinder end has simple and compact structure and low cost.
Description
Technical field
The utility model relates to a kind of cylinder head, particularly a kind of secondary air inlet cylinder head that is applied to motorcycle engine and general dynamic machinery.
Background technique
Along with people are more and more stronger to the consciousness of environmental protection, various countries are also more and more higher to the requirement of engine emission now.Therefore, on motor, increase the secondary air inlet check valve apparatus, utilize the secondary combustion of waste gas on cylinder head, and reduce discharging.As the patent No. is 200720106314.5 disclosed disjunctor tonifying Qi cylinder head patents, adopts thermal insulating pad and sealing gasket that one-way valve and cylinder head are coupled together, and outside individual event valve secondary air-supplementing valve is housed, and therefore such structure Assembly part is many, and cost is higher.
The model utility content
The purpose of this utility model is to provide a kind of secondary air inlet cylinder head simple in structure.
The purpose of this utility model is achieved through the following technical solutions: a kind of secondary air inlet cylinder head, comprise cylinder head, and described cylinder head has the secondary air inlet road that is communicated with air outlet flue, it is characterized in that: described secondary air inlet road is connected with one-way valve.
Described one-way valve can comprise one-way valve body and the unidirectional valve gap that matches with described one-way valve body.
Be further simplified structure, the import in described secondary air inlet road is provided with the die cavity that matches with described one-way valve body, and described one-way valve body is arranged in the described die cavity.
Be to guarantee the tightness of one-way valve, described one-way valve body is provided with seal ring and is used for sealing between one-way valve body and unidirectional valve gap and one-way valve body and the described die cavity.
The beneficial effects of the utility model are: because the body of secondary air inlet one-way valve directly is produced on the cylinder head, and by rubber seal on the one-way valve and unidirectional valve gap it is sealed, so the simpler compactness of overall structure, cost is lower.
Description of drawings
Fig. 1 is the utility model embodiment 1 a structural representation;
Fig. 2 is the explosive view of Fig. 1.
Embodiment
The utility model is described in further detail below by concrete mode of execution, but therefore the utility model is not limited among the following concrete mode of execution.
Embodiment 1: as depicted in figs. 1 and 2, a kind of secondary air inlet cylinder head comprises cylinder head 1, and described cylinder head 1 has the secondary air inlet road 3 that is communicated with air outlet flue 2, and described secondary air inlet road 3 is connected with one-way valve; Described one-way valve comprises one-way valve body 4 and the unidirectional valve gap 5 that matches with described one-way valve body 4; The import 3-1 in described secondary air inlet road 3 is provided with the die cavity 6 that matches with described one-way valve body 4, and described one-way valve body 4 is arranged in the described die cavity 6; Described one-way valve body 4 is provided with seal ring 7 and is used for sealing between one-way valve body 4 and unidirectional valve gap 5 and one-way valve body 4 and the described die cavity 6.
When adopting the engine operation of this cylinder head, the air that is filtered enters one-way valve by valve-chamber cover, directly enters secondary air inlet road 3 then, carries out secondary combustion with waste gas in the air outlet flue 2 in high temperature, thereby reduces the discharging of motor.
Claims (4)
1, a kind of secondary air inlet cylinder head comprises cylinder head (1), and described cylinder head (1) has the secondary air inlet road (3) that is communicated with air outlet flue (2), it is characterized in that: described secondary air inlet road (3) is connected with one-way valve.
2, secondary air inlet cylinder head as claimed in claim 1 is characterized in that: described one-way valve comprises one-way valve body (4) and the unidirectional valve gap (5) that matches with described one-way valve body (4).
