Description
Technical field
The utility model belongs to the structure-design technique field of spark plug, is specifically related to a kind of energy-saving spark plug.
Background technology
In order to solve problem of environmental pollution and the serious day by day energy problem that the vehicular engine discharging causes, countries in the world begin to greatly develop the substitute fuel automobile when the vehicular discharge rules of formulating various strictnesses are come the production and use of standard automobile.Because natural gas is in the advantage of aspects such as resource, cost, so gas-fueled vehicles develop rapidly, automobile repacking, natural gas store and a complete set of technology of gas station also reaches its maturity.Compare with gasoline, as engine fuel, not only can save petroleum resources, reduce fuel cost, and, can reduce the environmental pollution degree greatly as a kind of clean fuel with natural gas.In recent years, the research and development of plug ignition formula gas-fueled vehicles is risen rapidly in China, and test shows, adopts plug ignition formula natural gas engine effectively to reduce environmental pollution, meets present economy of China and demands of social development.
At present, mostly most gas-fueled vehicles are to adopt diesel vehicle to convert, in addition owing under the existence conditions, and the natural gas filling station rareness, and the diesel oil gas station is more relatively, so be the heat subject that the double fuel gas-fueled vehicles of fuel become everybody research and development with diesel oil, natural gas.
At present, be similar to the spark plug that uses on the conventional gasoline engin at the spark plug that uses on the natural gas engine, this kind spark plug comprises central electrode, lateral electrode, be used to separate the insulator of central electrode and lateral electrode and be used for lateral electrode is fixed on housing on the insulator, and the basic configuration that described lateral electrode is stretched out the outer ignition portion of main body is L shaped; Its process of lighting natural gas is to use injector to spray natural gas or diesel injection device in engine chamber, use spark ignitor again, because the spark plug arcing distance is shorter, spark gap also is that ionization channels has only 0.6mm～0.9mm, and the spark of its formation is hidden by lateral electrode, and lateral electrode also can absorb heat, causes gaseous mixture fully not burnt.The imperfect combustion of fuel is not only wasted fuel, also makes discharge tail gas can not reach standard; The imperfect combustion of fuel also can cause the sparking-plug electrode carbon deposit in addition, shortens the useful life of spark plug.
The utility model content
The purpose of this utility model provides a kind of fuel gas that can effectively make and fully burns, has the energy-saving spark plug of better environment protecting and energy-saving effect.
The technical scheme that realizes the utility model purpose is: a kind of energy-saving spark plug, has the spark plug main body, described spark plug main body comprises central electrode, lateral electrode, be used to separate the insulator of central electrode and lateral electrode and be used for lateral electrode is fixed on housing on the insulator, and the basic configuration that described lateral electrode is stretched out the outer ignition portion of main body is L shaped; Form a material-holding chamber between the bottom of described central electrode and the lateral electrode ignition portion, also be provided with the injection channel that is communicated with material-holding chamber in the described spark plug main body.
Described injection channel has import and outlet, and described outlet is arranged on the chamber wall of material-holding chamber.
Fixedly install the injector that is useful on burner oil on the described spark plug main body, the nozzle of described injector is communicated with material-holding chamber by injection channel.
Described spark plug main body is provided with in injection channel import department and is used for the connecting portion of fixedlying connected with injector.
The import of described injection channel is connected with injector nozzle.
Described injector is the cellular type injector.
The utlity model has positive effect: (1) the utility model is provided with a material-holding chamber between central electrode and lateral electrode ignition portion, and in the spark plug main body, also be provided with the injection channel that is communicated with material-holding chamber, in use, the import of injection channel can be communicated with the jet blower of external injector, when making fuel through the nozzle ejection, enter in the combustion chamber again after the process injection channel enters material-holding chamber, after this produce electric spark pilot fuel gas between central electrode and the lateral electrode ignition portion, because the concentration of the fuel in the material-holding chamber is higher than the mean concentration of gaseous mixture in the combustion chamber, the impact of the suffered vortex flow motion of the fuel that should locate simultaneously is less, form one can stable ignition the gaseous mixture environment, so can fuel gas fully be burnt, have better environment protecting and energy-saving effect.(2) the utility model can also be fixed on injector on the spark plug main body, and is convenient, quick when this will make that using the utility model makes engine, enhances productivity.(3) not only to can be used for gasoline, natural gas be on the engine of fuel to the utility model, and can also be used for diesel oil is the engine of fuel, just when be used for Diesel engine, to the spark plug energized; Simultaneously the utility model the most suitable be fuel with diesel oil and natural gas or be in the dual fuel engine of fuel to have the advantage that purposes is wide, the life-span is long with diesel oil and gasoline.
Description of drawings
Fig. 1 is the structural representation of first kind of execution mode of the utility model.
Fig. 2 is the structural representation of second kind of execution mode of the utility model.
Be labeled as shown in the accompanying drawing: spark plug main body 1, central electrode 11, lateral electrode 12, ignition portion 121, insulator 13, housing 14, injection channel 15, import 151, outlet 152, connecting portion 16, material-holding chamber 2, injector 3, nozzle 31.
Embodiment
(embodiment 1)
Fig. 1 has shown first kind of execution mode of the present utility model.
Present embodiment is a kind of energy-saving spark plug, has spark plug main body 1, described spark plug main body 1 comprises central electrode 11, lateral electrode 12, be used to separate the insulator 13 of central electrode 11 and lateral electrode 12 and be used for lateral electrode 12 is fixed on housing 14 on the insulator 13, and the basic configuration that described lateral electrode 12 is stretched out the outer ignition portion 121 of main body 1 is L shaped; Form a material-holding chamber 2 between the bottom of described central electrode 11 and the lateral electrode 12 ignition portions 121, also be provided with the injection channel 15 that is communicated with material-holding chamber 2 in the described spark plug main body 1.
