Abstract
An environment-protecting low and high electrode spark plug comprises a ceramic part of the spark plug and a nut. The top of a screw-thread iron shell connected with the ceramic part is provided with an integrated arc-shaped iron tower. The ceramic part is equipped with a central electrode and a low electrode. The spark plug is capable of ignition at a plurality of points to cause full combustion in a combustion chamber of an engine, which reduces the emission of carbon monoxide and other harmful gases, reduces the air pollution, and prolongs the usable life of the spark plug as well.
Description
Technical field
The utility model relates to a kind of engine spark plug, particularly multiple spot discharge-type spark plug.
Background technology
In the prior art, engine spark plug generally adopts traditional vertical discharge igniting of single branch center electrode.Consult the patent No. and be " energy-saving spark plug " patent documentation of 94246791.4, discharge vertical of tower iron at engine spark plug screw thread iron-clad top with central electrode, be the short distance discharge, in use for some time, little because of lighting spark, the gaseous mixture of engine chamber can not completing combustion, and the pernicious gases such as carbon monoxide of being discharged increase, and the power of engine descends.Fuel combustion is insufficient to cause central electrode surface oxidation or deposition grease, can cause short circuit phenomenon when serious and can't discharge igniting.
Summary of the invention
The purpose of this utility model is to overcome above deficiency; a kind of multiple spot discharge-type height electrode environmental protection spark plug is provided; the engine chamber combustion efficiency is improved; reduce the pernicious gas amounts such as carbon monoxide of discharging; prolong the time of grease deposition or chemical deposition, and then the useful life of extending plug.
The purpose of this utility model realizes by following measure; height electrode environmental protection spark plug comprises Sparking Plug Insulator and nut; integrated arc tower iron 2 is arranged at screw thread iron-clad 1 top that connects with Sparking Plug Insulator; the corresponding lengthening of height of the central electrode 3 that is electrically connected with Sparking Plug Insulator; a plurality of low electrodes 4 are equipped with at the top that the Sparking Plug Insulator of central electrode 3 is housed simultaneously, and low electrode 4 is electrically connected with central electrode 3.
The above-mentioned low electrode that is contained in the Sparking Plug Insulator top is 1-4.
Above-mentioned cylindricality low electrode (4) is 0.4-2.2mm with the diameter of central electrode (3).
The utility model has the advantages that: because integrated arc tower iron is arranged at the screw thread iron-clad top that connects with Sparking Plug Insulator, the top of Sparking Plug Insulator is equipped with central electrode and a plurality of low electrode simultaneously, the central electrode of spark plug and the discharge of arc tower iron level, low electrode and vertical discharge of arc tower iron, it is effective to light a fire, and makes the engine chamber fuel combustion abundant, can reduce discharge of harmful gases amounts such as carbon monoxide, reduce air pollution, simultaneously the useful life of extending plug.
Description of drawings
The utility model has the following drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing at Fig. 1 top.
Fig. 3 has the Sparking Plug Insulator structural representation of 2 electrode mounting holes for the top.
Fig. 4 has the Sparking Plug Insulator structural representation of 3 electrode mounting holes for the top.
