Abstract
The utility model provides a purification spark plug for spark ignition internal-combustion engine mainly comprises insulator, ignition electrode, ground connection side electrode, external highly compressed purification electrode and metal casing, except that utensil ignition function, under the effect of external high pressure, purifies the electrode and produces no spark discharge, purifies waste gas ionization. Has the advantages of simple structure, convenient installation and good purification effect.
Description
The utility model belongs to internal-combustion engine ignition, particularly relates to a kind of spark plug with purification function of spark-ignition internal combustion engine.
Contain oxious components such as HC, CO in the spark-ignition internal combustion engine exhaust gas discharged, contaminated environment, health risk.For eliminating or alleviating this pollution, people develop the whole bag of tricks and device, but all have complex structure, install and do not make the not good enough defective of effect.
The purpose of this utility model is simpler, easy to install, the clean-up effect of a kind of structure of a design spark-ignition internal combustion engine waste gas purification apparatus preferably.
The utility model purpose realizes with following Purifying sparking plug design.It is made of ignitor, ground connection lateral electrode, insulator and the metal shell of external priming supply, it is characterized in that being provided with in the spark plug purged electrode of external purification high voltage source, so with the function combinations of single igniting and purifying exhaust air in same spark plug, realize igniting and waste gas purification simultaneously.
Fig. 1 is the utility model structural representation and embodiment, and Fig. 2 is Fig. 1 vertical view
1. ignitor 2. insulators 3. metal shells 4. ground connection lateral electrodes 5 purged electrode 6. inner washers
In conjunction with the accompanying drawings the utility model structure and operation principle are described further.Purged electrode 5 is formed with the electro-conductive glass welding in the pilot hole of insulator 2 by copper band Metallic rod and nickel system electrode; The ignitor side is formed with the electro-conductive glass welding in the pilot hole of insulator 2 by copper screw rod and nickel alloy electrode, and whole exhausted body and function inner washer 6 linings are contained in the steel shell 3; The lower surface of steel shell 3 crooked ground connection lateral electrode 4 insulators that have been welded make between purged electrode, ignitor, the steel shell and insulate, and purged electrode is located at insulator bottom; The skirt section shape of insulator is the circular cone post of two decentraction, and the purged electrode copper band arrives the nickel alloy electrode distance of ignitor greater than the nickel electrode of purged electrode to the distance of ignitor copper screw rod.This Purifying sparking plug ignition function is identical with the spark plug of existing single igniting, it purifies operation principle: after external high voltage is introduced purged electrode, high pressure produces the no-spark discharge, with emission molecule ionization, the activation in the cylinder, obtain participating in the activation energy that chemical reaction need have, increase the molecule number that is in the state of activation in the waste gas greatly, harmful substance is accelerated greatly to the chemical reaction velocity of harmless conversion, reach purifying exhaust air effectively.
The utility model is combined into one ignitor and purged electrode in spark plug, except that the tool ignition function, also have the function with waste gas purification in the cylinder of internal combustion engine, and is simple in structure, make in installation good purification.
