Abstract
The utility model discloses a swirl intake valve which comprises a valve cover, a valve stem and a valve lock catch. A connection surface of the back of the valve cover and the valve stem is provided with 3-8 swirl vanes which are arc-shaped. The included angle between the swirl vanes and the circumferential tangent line of the intake valve cover is 45-90 degrees. The swirl intake valve has the advantages of exquisite structure, low manufacturing cost and strong universality. By using the swirl intake valve, the gas mixture in the existing cylinder is improved, the sufficient combustion is promoted, the motive power is increased, the oil consumption is reduced, and the purpose of saving energy and reducing emission is achieved.
Description
Technical field
The utility model belongs to auto parts machinery and makes the field, and the intake valve that relates in particular to motor car engine manufactures and designs.
Background technique
Intake valve is the critical piece of motor, and the back of existing intake valve is smooth, and the burning desired gas directly enters cylinder under pressure.And the even more burning of gas mixing is abundant more in the cylinder.
Traditional combustion system air-flow rotation is to rely on the rotation of chamber structure shape extruding mixed gas, and rotational speed is subjected to the restriction of engine speed, and only the air-flow rotation mixes better when the high rotating speed of motor, and is low, and medium speed rotation mixed gas quality is relatively poor.No matter be compression ignition engine or spark-ignition engine, under full operating mode, all need a good air-flow rotational speed, impel oil fully to mix with air, mixed gas quality mixes homogeneous more, firing effect is abundant more, the smog of discharging is few more, and pollutant also can have a good exhaust index.
Summary of the invention
The utility model has improved engine intake valve at deficiency of the prior art, and the utility model is realized by following technical proposal:
Intake valve comprises valve cap, valve stem, valve collet, at the back and the valve stem junction surface of valve cap swirl vane is arranged.Swirl vane can be an arc.Swirl vane is 3 to 8, and the angle between the swirl vane is identical.The best is 6.
Further the angle of all tangent lines in the outer garden of swirl vane and air inlet door closure is that 45 degree are to 90 degree.The best is 60 degree.
The utility model rotary flow type intake valve is an arcuate shape of utilizing swirl vane, and mixed airflow is changed over the rotation lamina, makes mixed gas rotation oil reservoir.And the oil reservoir of two kinds of different concentration all rotates at a high speed towards same direction, the requirement of rotation mixed gas quality, and by the size of intake valve diameter, what determine the angle of rotation blade and quantity.Large compression ignition engine can be designed to 8 blades, small-sized combustion engine can be designed to 4 blades, generally all adopt 6 blades more, the gradient of blade can be according to the build size of motor, adopt different angles, most 60 degree that adopt are controlled at vane thickness under the prerequisite that does not influence intensity own in order to reduce gas-flow resistance as much as possible, can be designed as thin type or extra-thin.
Intake valve has valve port, and valve links to each other with valve stem, and valve end is provided with valve collet, and swirl vane is located at the connection part between valve and the door bar.
The utility model delicate structure, cheap, highly versatile uses the utility model to improve the interior gas admixture of present cylinder, promotes fully burning, strengthens power, reduces oil consumption, reaches energy-conservation row's purpose.
Description of drawings
The present invention will be further described below in conjunction with accompanying drawing.
Fig. 1, rotary flow type air valve structure sketch;
Fig. 2, Figure 1A-A face plan view;
Among the figure: the 1st, valve cap, the 2nd, swirl vane, the 3rd, valve stem, the 4th, valve collet, the 5th, the angle of all tangent lines in the outer garden of swirl vane and air inlet door closure.
Embodiment
Fig. 1 is the intake valve with four groups of swirl vanes, comprises air inlet door closure 1, and valve cap 1 back is cast with four groups of swirl vanes 2; Swirl vane 2 is arcs, and the angle between each swirl vane 2 is identical, equidistantly is cast in valve cap 1 back.What be connected with valve cap 1 is valve stem 3; The tip portion of valve stem 3 has valve collet 4.
Fig. 2 be Fig. 1 along A-A face plan view, swirl vane 2 is arcs as can be seen, wherein outer garden week of swirl vane and air inlet door closure tangent line angle 5 be 60 degree.
In fact swirl vane 2 can be 3 to 8, and swirl vane 2 is can be 45 to 90 degree with the angle 5 of all tangent lines in air inlet door closure 1 outer garden.Utilize the arcuate shape of swirl vane 2, mixed airflow is changed over the rotation lamina, make mixed gas rotation oil reservoir.And the oil reservoir of two kinds of different concentration all rotates at a high speed towards same direction, the requirement of rotation mixed gas quality, and by the size of intake valve diameter, what determine the angle of rotation blade and quantity.Large compression ignition engine can be designed to 8 blades, small-sized combustion engine can be designed to 4 blades, generally all adopt 6 blades more, the gradient of blade can be according to the build size of motor, adopt different angles, most 60 degree that adopt are controlled at vane thickness under the prerequisite that does not influence intensity own in order to reduce gas-flow resistance as much as possible, can be designed as thin type or extra-thin.
