Abstract
The utility model discloses a heat insulating type internal combustion engine spark plug which comprises an electrode, a heat insulating tube, a wire, a heat insulating connector, a heat dissipating net and a porcelain tube. The electrode is connected with one end of the wire and then installed at one end of the heat insulating tube. The wire penetrates through the heat insulating tube. The porcelain tube is installed on the wire in a sleeved mode, and a certain distance is kept between the porcelain tube and the heat insulating tube. The heat dissipating net is installed on the wire in a sleeved mode, and a certain distance is kept between the heat dissipating net and the porcelain tube. The heat insulating connector is connected with the wire, and a certain distance is kept between the heat insulating connector and the heat dissipating net. Compared with the prior art, a plurality of layers of heat insulation is adopted for the electrode of the spark plug, after heat is conducted out, the heat is insulated through the porcelain tube at first, the remaining heat on the wire is effectively dissipated through the heat dissipating net, and therefore the effect of efficiently dissipating the heat is achieved, heat dissipation towards the outside is effectively reduced, the service life is prolonged, and the spark plug has the application and popularization value.
Description
Technical field
The utility model relates to a kind of sparking plug for internal combustion engine, relates in particular to a kind of heat insulation type sparking plug for internal combustion engine.
Background technology
Spark plug (spark plugs), is commonly called as nozzles, and its effect is the high voltage pulse discharge of electricity that high-voltage conducting wires is sent here, and air between disruptive spark plug two electrodes produces electric spark with the mist in this cylinder that ignites.Main Types has: pseudotype spark plug, edge body projected nose type spark plug, electrode type spark plug, seat type spark plug, polar form spark plug, face arcing type spark plug etc.The function of spark plug is that the high-tension electricity of volts up to ten thousand is introduced to combustion chamber, and produce electric spark and light gaseous mixture, coordinate and make engine work done with ignition system and oil supply system, jointly determining to a great extent the performance of engine, yet, existing spark plug all conducts heat than being easier to, the connecting line that causes rear end is excess Temperature also, and the transmission that the excess Temperature of conductor will affect electric current is affected, and will directly affect sparking effect, therefore, the heat dissipation problem of spark plug needs further to improve.
Utility model content
The purpose of this utility model provides a kind of heat insulation type sparking plug for internal combustion engine with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises electrode, instlated tubular, wire, heat insulation joint, radiator-grid and porcelain tube, described electrode is connected afterwards and is installed on one end of instlated tubular with one end of wire, described wire is through described instlated tubular, described porcelain tube be set on described wire and and described instlated tubular between keep certain distance, described radiator-grid be set on described wire and and described porcelain tube between keep certain distance, described heat insulation joint be connected with described wire and and described radiator-grid between keep certain distance.
As a kind of improvement, described instlated tubular is also set with nut outward; On described nut, be set with seal washer.
The beneficial effects of the utility model are:
The utility model is a kind of heat insulation type sparking plug for internal combustion engine, compared with prior art, sparking-plug electrode of the present utility model adopts multilayer insulation, when temperature conduction out after, first pass through porcelain tube heat insulation, Yu Wenzai on wire effectively dispels the heat through radiator-grid, thereby play the effect of high efficiency and heat radiation, effectively reduce temperature and spread out of, improve useful life, there is the value of applying.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-electrode, 2-seal washer, 3-nut, 4-instlated tubular, 5-wire, 6-heat insulation joint, 7-radiator-grid, 8-porcelain tube.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1: the utility model comprises electrode 1, instlated tubular 4, wire 5, heat insulation joint 6, radiator-grid 7 and porcelain tube 8, electrode 1 is connected afterwards and is installed on one end of instlated tubular 4 with one end of wire 5, wire 5 is through instlated tubular 4, porcelain tube 8 be set on wire 5 and and instlated tubular 4 between keep certain distance, radiator-grid 7 be set on wire 5 and and porcelain tube 8 between keep certain distance, heat insulation joint be connected with wire 5 and and radiator-grid 7 between keep certain distance, the outer nut 3 that is also set with of instlated tubular 4; On nut 3, be set with seal washer 2.
During work, nut 3 is connected with tested EGR temperature spot by seal washer 2, when temperature conduction out after, first pass through porcelain tube 8 heat insulation, Yu Wenzai on wire 5 effectively dispels the heat through radiator-grid 7, thereby plays the effect of effectively insulating.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
