Abstract
The invention discloses a diversion type sparking plug protecting jacket of a gas engine. The diversion type sparking plug protecting jacket is formed by sequentially connecting a fixed jacket part, a connecting jacket part and a diversion jacket part. The centerline of an inner hole of the fixed jacket part, the centerline of an inner hole of the connecting jacket part and the centerline of an inner hole of the diversion jacket part are collinear. The inner hole of the diversion jacket part is a big-end-out bell mouth. The diversion jacket part is provided with ventilation holes throughout the inner wall and the outer wall of the diversion jacket part. By the adoption of the structure, the diversion type sparking plug protecting jacket is installed on a cylinder cover, so the influence on ignition stability by a flow field can be reduced. As the inner hole of the diversion jacket part is provided with a diversion surface, the flow field in a cylinder can develop in the reasonable direction, and then flame is guided to develop in the ideal direction. Meanwhile, the compression ratio of the engine can be further increased, the lean-burn coefficient can be also increased, and power and efficiency can be improved remarkably.
Description
Technical field
The invention belongs to technical field of internal combustion engines, be specifically related to a kind of gas engine flow guiding type spark plug protective sleeve.
Background technology
To premixed spark plug ignition IC engine; the parameters such as in-cylinder mixture strength, current rate, pressure, temperature, spark energy, ignition duration, electrode gap have impact to flammability; for ensureing stable ignition; some engine producers adopt premixed spark plug at present; enriching is carried out to ensure stable ignition to the mixture strength in premixed spark plug; but it is higher owing to introducing dense gaseous mixture cost; therefore advantage is not obvious; therefore; for ensureing stable ignition, design low cost and the protective sleeve that can improve delivery efficiency necessitates.
Summary of the invention
For solving above technical problem, the invention provides a kind of gas engine flow guiding type spark plug protective sleeve that can play protection igniting, pilot flame development.
Its technical scheme is as follows:
A kind of gas engine flow guiding type spark plug protective sleeve; its main points are: comprise connect successively fixed cover portion (1), adapter sleeve portion (2) and flow guide sleeve portion (3); the inner hole centreline conllinear of described fixed part cover (1), adapter sleeve portion (2) and flow guide sleeve portion (3); the endoporus of described flow guide sleeve portion (3) is inner small and outside big horn mouth, and described flow guide sleeve portion (3) is provided with the steam vent (4) running through this flow guide sleeve portion (3) inside and outside wall.Adopt above structure, the present invention is arranged in cylinder head, the impact of flow field on Ignition Stability can be reduced, Flow field can be made to rational future development after the endoporus in flow guide sleeve portion arranges guide face, thus pilot flame develops to ideal orientation.Meanwhile, engine compression ratio can further improve, and lean-burn coefficient also can improve, and power, efficiency all can increase.
As preferably: described fixed cover portion (1), adapter sleeve portion (2) and flow guide sleeve portion (3) are connected to form the little ladder cover in large flow guide sleeve portion (3) of fixed cover portion (1), so can be good at the connection realizing the present invention and spark plug, lean-combustion engine is lighted a fire more stable.
As preferably: the endoporus of described adapter sleeve portion (2) is screwed hole.
As preferably: described steam vent (4) is odd number, this steam vent of odd number (4) evenly and hoop be distributed on described flow guide sleeve portion (3), have a small amount of circular hole, ensure that waste gas can be got rid of in cylinder, add combustion rate.
As preferably: described steam vent (4) is near the inner of described flow guide sleeve portion (3), and waste gas like this is discharged more thorough.
As preferably: described fixed part cover (1), adapter sleeve portion (2) and flow guide sleeve portion (3) are wholely set.
Beneficial effect: the present invention be arranged in cylinder head, can reduce the impact of flow field on Ignition Stability, Flow field can be made to rational future development, thus pilot flame develops after the endoporus in flow guide sleeve portion arranges guide face to ideal orientation.Meanwhile, engine compression ratio can further improve, and lean-burn coefficient also can improve, and power, efficiency all can more obviously increase.

Embodiment
Below in conjunction with embodiment and accompanying drawing, the invention will be further described.
A kind of gas engine flow guiding type spark plug protective sleeve as depicted in figs. 1 and 2, comprise the fixed cover portion 1 connected successively, adapter sleeve portion 2 and flow guide sleeve portion 3, described fixed part cover 1, adapter sleeve portion 2 and flow guide sleeve portion 3 are wholely set, described fixed cover portion 1, adapter sleeve portion 2 and flow guide sleeve portion 3 are connected to form the little ladder cover in large flow guide sleeve portion 3 of fixed cover portion 1, described fixed part cover 1, the inner hole centreline conllinear in adapter sleeve portion 2 and flow guide sleeve portion 3, the endoporus in described adapter sleeve portion 2 is screwed hole, the endoporus in described flow guide sleeve portion 3 is inner small and outside big horn mouth, described flow guide sleeve portion 3 is provided with the steam vent 4 running through this flow guide sleeve portion 3 inside and outside wall, described steam vent 4 is odd number, this steam vent 4 is even and hoop is distributed in described flow guide sleeve portion 3, described steam vent 4 is near the inner in described flow guide sleeve portion 3.
Refer to Fig. 3, Fig. 4, Fig. 5 and Fig. 6: use combustion analysis software converge to do not add protective sleeve and add protective sleeve spark plug carry out combustion analysis; and combustion analysis result of calculation is contrasted: as seen from the figure; after spark plug is protected; can correct flame makes it develop from cylinder centerline; its whole combustion process degree of constant volume increases; burn more concentrated, thus raise the efficiency more than 2%.During igniting, Flow Field outside reduces the interference of igniting, and Ignition Stability increases, and protective sleeve has small sircle hole, and this small sircle hole is positioned at sparking-plug electrode upper end, can not disturb igniting, plays the effect of scavenging cooling.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but meet the most wide region consistent with principle disclosed herein and features of novelty.
