Abstract
The invention discloses a double sparking plug cylinder cap, which comprises at least one spherical combustion chamber. The spherical combustion chamber is provided with an air inlet, an air outlet, a first sparking plug hole and a second sparking plug hole, wherein, the air inlet is communicated with an air intake passage, and the air outlet is communicated with an air drain passage. The invention is characterized in that: a burbling piece for disturbing flow is arranged near each sparking plug hole on the circumference of the base plane of the combustion chamber. Each burbling piece has a burbling surface on the base plane of the combustion chamber, and the projection of each burbling piece on the base plane is an obtuse triangle. As the invention adopts two sparking plugs for ignition, the flame travel is reduced and accordingly the combustion time is also reduced, thereby enabling adoption of greater compression ration to improve the economical efficiency of an engine. As one burbling piece for disturbing flow is arranged near each sparking plug hole on the circumference of the base plane of the combustion chamber, the combustion chamber is designed into a double burbling type combustion chamber, thereby further improving combustion gas distribution in the combustion chamber and increasing combustion stability. The invention is applicable to various combustion engines.
Description
Technical field
The present invention relates to a kind of engine cylinder cover, relate in particular to a kind of cylinder cover with double sparking plugs.
Background technique
The major function of cylinder head is closed cylinder top, and forms the firing chamber with piston head and cylinder wall.There is cooling jacket cylinder head inside.The cylinder of Overhead valve is stamped inlet and outlet gate seat and valve guide hole and inlet and outlet gas passage etc.
At present, known petrol engine is to adopt a spark plug to carry out the ignition of mixed steam, flame travel is long, and period of combustion is long, and the thermal efficiency is low, pinking easily simultaneously, therefore the raising of the compression ratio of motor is restricted, and causes the Economy of motor bad, need shift to an earlier date owing to ignition advance angle simultaneously, cause arranging Wen Bugao, be unfavorable for the ignition of three-element catalytic.
Chinese patent 200520006166.0 discloses a kind of parallel symmetric double spark plug firing chamber.Its technological scheme is made up of cylinder cap, cylinder body and piston, and two spark plugs are installed in the upper end of cylinder cap symmetrically and stretch in the firing chamber.Its deficiency is that the burning indoor fuel gas distributes inadequately rationally, causes combustion characteristic good inadequately, and the spark plug layout is also reasonable inadequately, and does not relate to the concrete cylinder cap structure of dual ignition plug motor.
Summary of the invention
In order to overcome the deficiency that existing cylinder cap exists, the object of the present invention is to provide a kind of cylinder cover with double sparking plugs, this cylinder cap not only burns, and indoor fuel gas distributes more rationally, combustion characteristic is good but also rational in infrastructure, safe and reliable.
The technical solution adopted for the present invention to solve the technical problems is: a kind of cylinder cover with double sparking plugs, comprise at least one spherical combustion chamber, and spherical combustion chamber is provided with suction port, relief opening, first spark-plug hole and second spark-plug hole; Suction port is communicated with intake duct, and relief opening is communicated with air outlet flue; It is characterized in that: the crowded stream spare that a flow-disturbing effect is respectively arranged near the spark-plug hole position at the bottom plane of described firing chamber circumference.
In order to make spark plug cylinder cap combustion stability better, described crowded stream spare is in the bottom plane of firing chamber crowded stream interface to be set, and it is at the projection join line of bottom plane triangle in obtuse angle.
In order to improve combustion characteristic, it is more reasonable that spark plug is arranged, first spark-plug hole is positioned at the centre in suction port and territory, relief opening one lateral areas, and oblique towards the air outlet flue inclination; Second spark-plug hole arranges with respect to the opposite side that first spark-plug hole is positioned at the firing chamber, and oblique towards the intake duct inclination.Described first spark-plug hole is stretched out from the relief opening flanged surface; Stretch out on described second spark-plug hole plane from the cylinder cap.
Good effect of the present invention is: because it mainly adopts dual ignition, reduce flame travel, thereby reduce period of combustion, thereby can adopt bigger compression ratio, improve the Economy of motor, and be difficult for pinking, thermal efficiency height.Improve combustion stability simultaneously and introduced EGR; And ignition advance angle was more originally postponed, improved delivery temperature.The firing chamber has further been improved the burning indoor fuel gas and has been distributed by respectively having the crowded stream spare of a flow-disturbing effect to be designed to two squish type chambers at the bottom plane circumference near the spark-plug hole position, has improved combustion stability.
The present invention is further illustrated below in conjunction with drawings and Examples.
