Abstract
The utility model discloses a kind of squeezing and flow cylinder cap, comprise the cylinder cap body being provided with firing chamber epicoele; The crowded stream part just right with cylinder inner cavity is provided with in the epicoele of described firing chamber; Crowded stream cylinder cap of the present utility model, hierarchic structure is formed with cylinder inner wall by the crowded stream part in the epicoele of firing chamber, inflammable gas eddy motion under the effect of this hierarchic structure can be made, be beneficial to abundant mixing, be beneficial to raising velocity of combustion, reduce thermal loss, improve Economy and the power character of motor.
Description
Technical field
The utility model relates to a kind of engine cylinder cover, particularly relates to a kind of squeezing and flows cylinder cap.
Background technique
Cylinder cap coordinates with piston cylinder and piston and forms firing chamber, by inflammable gas in firing chamber combustion, produce high-temperature high-pressure fuel gas expansion work, and then promoting piston movement drive crankshaft rotating Driving Torque, the cavity of cylinder cap respective combustion chamber is firing chamber epicoele, and in prior art, the firing chamber epicoele of cylinder cap is consistent with cylinder inner cavity size and profile, level and smooth docking after installing, inflammable gas flows along Inner Wall of Combustion Chamber, is unfavorable for the mixing of inflammable gas, and Economy and power character are slightly poor.
Model utility content
In view of this, the purpose of this utility model is to provide a kind of squeezing and flows cylinder cap, makes inflammable gas eddy motion, is beneficial to abundant mixing, be beneficial to raising velocity of combustion, reduce thermal loss, improves Economy and the power character of motor.
Crowded stream cylinder cap of the present utility model, comprises the cylinder cap body being provided with firing chamber epicoele; The crowded stream part just right with cylinder inner cavity is provided with in the epicoele of described firing chamber;
Further, described crowded stream part is extended to form in the epicoele of firing chamber by cylinder cap body;
Further, to arrange multiple and each crowded stream part uniform along respective combustion chamber epicoele circumference for described crowded stream part corresponding each firing chamber epicoele;
Further, described crowded stream part corresponding each firing chamber epicoele arranges two and makes firing chamber epicoele be oblate cross-sectional.
The beneficial effects of the utility model are: crowded stream cylinder cap of the present utility model, hierarchic structure is formed with cylinder inner wall by the crowded stream part in the epicoele of firing chamber, inflammable gas eddy motion under the effect of this hierarchic structure can be made, be beneficial to abundant mixing, be beneficial to raising velocity of combustion, reduce thermal loss, improve Economy and the power character of motor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Fig. 1 is structural representation of the present utility model, as shown in the figure: the crowded stream cylinder cap of the present embodiment, comprises the cylinder cap body 1 being provided with firing chamber epicoele 2; The crowded stream part 3 just right with cylinder inner cavity is provided with in described firing chamber epicoele 2; Cylinder inner cavity is the diameter cylindrical cavity consistent with firing chamber epicoele 2 maximum diameter, hierarchic structure is formed with cylinder inner wall by the crowded stream part 3 in firing chamber epicoele 2, inflammable gas eddy motion under the effect of this hierarchic structure can be made, be beneficial to abundant mixing, be beneficial to raising velocity of combustion, reduce thermal loss, improve Economy and the power character of motor.
In the present embodiment, described crowded stream part 3 is extended to form in firing chamber epicoele 2 by cylinder cap body 1, and namely crowded stream part 3 is one-body molded with cylinder cap body 1, and compact structure, easily manufactures, and can save manufacture cost.
In the present embodiment, it is uniform along respective combustion chamber epicoele 2 circumference that described crowded stream part 3 corresponding each firing chamber epicoele 2 arranges multiple and each crowded stream part 3, firing chamber epicoele 2 and cylinder inner cavity joint is made to form many places hierarchic structure, strengthen the eddy motion of inflammable gas, improve the mixability of inflammable gas, further raising velocity of combustion, reduces thermal loss, improves Economy and the power character of motor.
In the present embodiment, described crowded stream part 3 corresponding each firing chamber epicoele 2 arranges two makes firing chamber epicoele 2 for oblate cross-sectional, is convenient to the manufacturing of cylinder cap, is beneficial to cost-saving, ensure combustion chamber volume simultaneously.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
