The spray with good atomization and controllable penetration distance is very beneficial to the formation of combustible mixture, accelerates the combustion speed, and significantly improves the power, economy and emission indicators of the engine.
Description
Technical field
The utility model relates to a kind of internal-combustion engine internal cone type atomising device that play the guiding role, realizes secondary-atomizing, belongs to engine mixed gas and forms and combustion field.
Background technique
At present, the excess air coefficient of diesel engine is more easy over-emitting black exhaust, and its main cause is because in a circumferential direction inhomogeneous of porous spraying, and produces the overrich district at the drop point place of spraying.In order to address this problem, though the umbrella-shaped spray atomization of generation is good, circumferencial direction is evenly distributed, but penetrating force is not strong.Therefore, in better performances under the low operating mode, have more than is needed because of firing chamber peripheral air profit under high operating mode, black smoke increases more.
Summary of the invention
For drop point place mixed gas overrich and the circumferential skewness that solves the porous spraying, and umbrella-shaped spray runs through apart from short problem, the utility model provides a kind of internal-combustion engine internal cone type atomising device, this internal-combustion engine internal cone type atomising device can provide atomization good, circumferentially be evenly distributed, run through apart from controlled spraying.
The technological scheme that its technical problem that solves the utility model adopts is: in the firing chamber that cylinder head, piston and cylinder liner are formed, an internal cone type guiding cone is set directly over perforated plate type atomizer, and make the interior cone angle of oil bundle angle β greater than the guiding cone, can be sprayed onto on the inner conical surface of guiding cone to guarantee oily bundle.Internal cone type guiding cone is arranged on the lower end that is installed on the cylinder head inner sleeve, and the cone that also can internal cone type leads and cylinder head are set to one, are positioned at the cylinder head lower plane place of oil nozzle periphery.When the oil bundle that gushes out from oil nozzle is run into the inner conical surface of guiding cone, realize secondary-atomizing, the oil bundle launches along the conical surface, is fan-shaped ejection.What can guarantee like this to spray circumferentially is evenly distributed, because can adjust and run through apart from size by changing the angle of oil bundle and the guiding conical surface, be rebuffed to avoid the oil bundle, thereby it is good to obtain atomization, circumferentially is evenly distributed, and runs through apart from controlled spraying purpose again.
The beneficial effects of the utility model are: because the inner conical surface of guiding cone makes the oil bundle launch along the conical surface, present fan-shaped ejection, atomization is good, circumferentially be evenly distributed, run through, realize secondary-atomizing apart from controlled, greatly improved the quality of engines combustible mixed gas, made burning rapidly with perfect.Under declared working condition, add the guiding cone after, smoke intensity 1 ripple that descends is permitted value, oil consumption descends more than 5%, other exhaust indexs of motor also have clear improvement; If the value when keeping smoke intensity to lead cone for not adding, power can improve about 10%.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is first embodiment's of internal-combustion engine internal cone type atomising device a longitudinal section tectonic maps.
Fig. 2 is second embodiment's of internal-combustion engine internal cone type atomising device a longitudinal section tectonic maps.
Among the figure: 1, cylinder head, 1a, inner conical surface, 2, cylinder liner, 3, piston, 4, the firing chamber, 4, oil nozzle, 5, sleeve pipe, 5a, inner conical surface, 6, primary oil beam, 7, secondary oil beam, 8, oil nozzle.
Embodiment
In the embodiment shown in fig. 1, cylinder head (1), cylinder liner (2) and piston (3) are formed a toroidal combustion chamber (4), the middle part of cylinder head (1) is equipped with oil nozzle (8), and the outside of oil nozzle (8) is sleeve pipe (5), and sleeve pipe (5) lower end is provided with internal cone type guiding cone.When oil nozzle (8) during to inner conical surface (5a) the ejection primary oil beam (6) of guiding cone, primary oil beam (6) expands to circumferentially more uniform secondary oil beam (7) under the guiding of inner conical surface, under the air motion effect of secondary oil beam (7) in firing chamber (4), form the more inflammable mixture of homogeneous.
Shown that in Fig. 2 internal cone type guiding cone directly is set to one with cylinder head (1), and be positioned at the lower plane place of the peripheral cylinder head (1) of oil nozzle (8).
In above-mentioned two embodiments, the angle β of the primary oil beam (6) of identical is oil nozzle (8) should be greater than the interior cone angle of guiding cone, and guarantees that primary oil beam (6) drops on the guiding inner conical surface, in order to forming secondary oil beam (7) of fine quality.
