Description
Technical field
The invention belongs to the structure-design technique field of spark plug, be 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 practice thrift 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 because under the existence conditions, natural gas filling station is rare; 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 the housing on the insulator, and the basic configuration that said 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 in engine chamber, spraying natural gas or diesel injection device; 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 the gaseous mixture can not be by abundant burning.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.
Summary of the invention
The purpose of this invention is to provide a kind of fuel gas that can effectively make and fully burn, have the energy-saving spark plug of better environment protecting and energy-saving effect.
The technical scheme that realizes the object of the invention is: a kind of energy-saving spark plug; Has the spark plug main body; Said 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 the housing on the insulator, and the basic configuration that said lateral electrode is stretched out the outer ignition portion of main body is L shaped; Form a material-holding chamber between the bottom of said central electrode and the lateral electrode ignition portion, also be provided with the injection channel that is communicated with material-holding chamber in the said spark plug main body.
Said injection channel has import and outlet, and said outlet is arranged on the chamber wall of material-holding chamber.
Fixedly install the injector that is useful on burner oil on the said spark plug main body, the nozzle of said injector is communicated with material-holding chamber through injection channel.
Said spark plug main body is provided with in injection channel import department and is used for the connecting portion that is fixedly connected with injector.
The import of said injection channel is connected with injector nozzle.
Said injector is the cellular type injector.
The present invention has positive effect: (1) the present invention 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, can the import of injection channel be communicated with the jet blower of external injector, when making fuel through the nozzle ejection; Through getting in the combustion chamber again behind the injection channel entering 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 effectively make fuel gas fully burn, have better environment protecting and energy-saving effect.(2) the present invention can also be fixed on injector on the spark plug main body, and is convenient, quick when this will make that using the present invention makes engine, enhances productivity.(3) not only to can be used for gasoline, natural gas be on the engine of fuel in the present invention, 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; The present invention simultaneously the most suitable be fuel with diesel oil and natural gas or be in the dual fuel engine of fuel to have that purposes is wide, a life-span advantage of length with diesel oil and gasoline.
