Abstract
The utility model relates to an ignition device for an internal combustion engine, particularly an energy saving spark plug which comprises a center electrode and a lateral electrode, wherein a middle relay fire jumping electrode is embedded in an insulation porcelain pipe between the center electrode and the lateral electrode. The utility model changes the traditional single discharge form and adopts the advanced exposed type structural design. During the ignition every time, two sparks are generated between the center electrode and the lateral electrode of the spark plug, which can lead burning mixture gas in a cylinder to be sufficiently burnt in time and can leads the oil consumption to be reduced.
Description
Technical field
The utility model relates to a kind of igniter of explosive motor, particularly a kind of energy-saving spark plug.
Background technology
The vitals that spark plug is used during for engine operation, the frequency of utilization height, the effect of igniting directly influences efficiency of engine, exhaust emissions.Traditional spark plug is single discharge type, and when spark is plugged with carbon distribution or high-tension electricity when weakening than normal value, the spark that produces at spark plug two interpolars will weaken, cause easily can not ato unit or engine operation bad.At present, for improving the ignition effectiveness of spark plug, the structure of spark plug has been carried out a lot of improvement and innovation, Chinese patent 200320111144 discloses a kind of spark plug, be characterised in that: be fixed with a polygonal center pole arcing plate in the central electrode end, on the central electrode of polygonal center pole arcing postlaminar part, insulating case is housed, on the insulating case between polygonal center pole arcing plate and the lateral electrode, be mounted with a middle hop fire ring, its shortcoming is: in application since the position class of spark like screened spark plug, when the concentration of gaseous mixture changes, be difficult for ato unit, in the use, because the cylinder pressure that constantly changes in the cylinder acts on center arcing plate and the middle hop fire ring, and parts are come off easily.
The utility model content
The utility model purpose be to provide a kind of simple in structure, ignition effectiveness is high, the energy-saving spark plug of long service life.
To achieve these goals, the utility model adopts following technical scheme: a kind of energy-saving spark plug comprises central electrode and lateral electrode, setting-in indirect power arcing electrode in the porcelain tube between central electrode and lateral electrode.
Relay arcing electrode to the gap of central electrode equals the gap of middle relay arcing electrode to lateral electrode in the middle of described, is 0.6～1.0mm.
Described lateral electrode two outsides have the elliptical aperture that can communicate with middle relay arcing electrode near middle relay arcing electrode place.
The terminal end for taper, middle relay arcing electrode of described central electrode is hemisphere.
The gradient of described elliptical aperture is 21 °.
Relay arcing electrode has two in the middle of described, is arranged in the porcelain tube with the central electrode axle center.
The utility model has changed traditional single discharge type, adopted advanced exposed conveying appliance structural design, each igniting produces two sparks between the central electrode of spark plug and lateral electrode, can make the combustion mixture fully burning in time in the cylinder, and reduce oil consumption; Elliptical aperture is to be convenient to combustion mixture fully contact with spark, is convenient to light.
