Abstract
It is well-known that the existing spark plug can cause leakage or short circuit because of oil leakage, carbon accumulation, over-thick mixed oil, deficient power, etc, thus causing starting difficulty or unable starting, running disability, fuel oil loss, maintenance increase, repeated creepage, etc. The invention is a no-misfiring spark plug at the time of creepage and short circuit, its central electrode is a nonconductive multilayer-gap spark plug integrated with electrode, ejection collection side electrode and ejection guide electrode, as the time of oil leakage and creepage or short-circuiting, the high pressure of the central electrode still continuously ignites and explodes under the action of ejection collection side electrode and ejection guide electrode. The practice proves that it reaches the effect of starting quickly, no misfiring, long service life, etc.
Description
The present invention relates to a kind of leak electricity short-circuit without misfiring spark plug, and can concentrate a kind of spark plug of radio, injection electric leakage.
At present, all be to adopt central electrode skirt body and shell to keep the space of certain distance since known gasoline engine is born, its depth of interstices and width have multiple size, and have standard type, pattern of fever and cold mould.Electrode has a utmost point, two utmost points, three utmost points, four utmost points, the circumference utmost point and the height utmost point, generally speaking, it is best all not having accurate data declaration the sort of regardless of the spark plug that is how many utmost points, but can affirm multipole or height utmost point discharge must make spark disperse, or has only partly limit fire, electric power is not concentrated, and ignition ability reduces causes the power of igniting poor, and it is not enough to fire power.The spark plug in space is arranged no matter be that what type all has a common characteristic, be exactly scurry oil, carbon deposit easily between this central electrode skirt body and the shell.Because the space is difficult to self-cleaning, when machine oil upper cylinder half or miscella overrich, electric power all can not start with inoperative inadequately smoothly.Because of lacking fiery phenomenon, electric leakage and short circuit often occur, especially more outstanding this defective on two-stroke internal combustion engine and old internal combustion engine.Igniting the time misfires to cause when often occurring does not have burning or gasoline that can not completing combustion and becomes waste gas and discharge, and serious environment pollution is wasted gasoline again.Must increase maintenance owing to often change spark plug, not only waste money but also waste time, not start at crucial moment, the total feel of problem is very tired for this reason for the driver.Particularly fire fighting truck, ambulance, police car, national defence car do not allow not move at significant instant.Spark plug leaks electricity repeatedly and just can not use again, and a new spark plug is often changed because of leak electricity short-circuit, and its life-span is to die young because of leak electricity short-circuit.
The technology that the present invention solves its technical problem employing is: in central electrode, be divided into two sections or multistage, and intersegmental reservation best clearance, platinum or the alloy that millet cake adopts good conductivity touched in the arcing of central electrode.The top of central electrode to terminal is a nonconducting electrode, is unique in the world present spark plug.Form solid insulation skirt in order to reach better self-cleaning effect and to avoid long carbon deposit also can cancel during the spark plug burning to the space of center electrode insulation space skirt body and shell.Any optimum position of this external central electrode insulation space skirt body or insulated solid skirt body is provided with an injection electrode and is connected with shell, when scurrying oil or carbon deposit electric leakage, spark plug can play the electric ignition effect of drawing, in order to draw electric better effects if, at the fastening metallic shield circle of loading onto in the top of center electrode insulation space skirt body or the solid skirt body of center electrode insulation, the injection electrode is located on the optimum distance with the 3rd section of metallic shield circle and central electrode and with shell and is connected.Form forceful electric power for making high-tension electricity more concentrate on the peak percussion, lateral electrode and central electrode can adopt hemisphere radio, cone radio, cylinder inclined-plane radio, cylindrical side radio, peak, limit radio according to the structure needs.In the experiment, when spark plug was scurried oily short circuit and carbon deposit short circuit, spark plug of the present invention was unaffected, ignites in the same old way, and general spark plug is not accomplished.
The invention has the beneficial effects as follows: no matter new internal combustion engine or old internal combustion engine, no matter be that quartastroke engine or two-stroke internal combustion engine can both Fast starting, avoided because of scurrying the leak electricity short-circuit that oil causes, at the cylinder body lubricating oil carry-over, when scurrying gasoline, this spark plug can both solve, even the surface has carbon deposit fiery phenomenon also can not occur lacking, current spark plug can not be accomplished, greatly reduce maintenance simultaneously, reduce and change, long service life, make combustion engine powered powerful, more save fuel oil, reduce toxic emission, environment purification is played an important role, use extensively, especially important vehicle can both start at crucial moment, had long-range and tangible economic benefit.
The component structure that is adopted is simple, and the present invention is further described below in conjunction with drawings and Examples.
