Abstract
The utility model relates to an electric ignition spark plug for a combustion engine. The top end of a thread plug body of the spark plug is provided with an annular outer electrode, two discharge rings are axially arranged and fixed on a corresponding central electrode, and porcelain insulating rings are arranged between and at both sides of the two discharge rings. The utility model has the remarkable advantages of obviously widening the direct action ranges of electric sparks and prolonging action time.
Description
The utility model relates to a kind of internal combustion engine electric ignition spark plug.
Existing spark plug constitutes discharging gap by central electrode and lateral electrode, and two electrodes are separated by the porcelain insulating layer and supported, and lateral electrode and metal threaded cock body are one, and bar-shaped central electrode is provided with high voltage source and imports chock plug.Above-mentioned spark clearance adjusting range is very limited, spark is less to the sphere of action of burning mixture direct-fire in the cylinder, and action time is shorter, deficiency so that burning mixture fully burn, cause the fuel oil consumption big and power is lower, exhaust emissions is second-rate.A kind of its lateral electrode of improved spark plug increases to 3 and is the plum blossom shape, and it only can make electric spark become the pencil spark of three different directions, still can not obviously increase the direct sphere of action of spark, more can not prolong the action time of electric spark.
The purpose of this utility model provides a kind ofly can obviously increase the direct sphere of action of electric spark, prolong the electric spark novel energy-conserving spark plug of action time.
Above-mentioned purpose of the present utility model is achieved in that the top of screw thread cock body is an annular external electrode, and central electrode axially-aligned corresponding with it is fixed with two discharge rings, and between the two discharge rings and both sides are provided with the porcelain dead ring.
Said two discharge ring outer faces are higher than the porcelain dead ring.
Further specify the utility model below in conjunction with drawings and Examples.
Accompanying drawing 1 the utility model example structure is partly cutd open schematic diagram
Among the figure top of metal threaded cock body 3 be annular external electrode 3 ', central electrode 1 corresponding with it be provided with two fixing discharge rings 1 of axially-aligned ', between the two discharge rings and both sides are provided with porcelain dead ring 4, discharge ring 1 ', the outer face be higher than the porcelain dead ring.The porcelain dead ring and the porcelain insulating barrier of discharge ring downside are one in the present embodiment.
Under the high-voltage pulse effect, annular external electrode 3 produces the gap discharge phenomenon at first and between the close discharge ring and presents the ring-type electric spark, the electric spark that it is obviously produced greater than existing point electrode gap discharge the direct-fire sphere of action of burning mixture in the cylinder, therefore the gas in the jar area that ignites is big, and the formation that fires is continuously subsequently speeded up.Discharge ring hysteresis discharge with annular external electrode 3 ' apart from each other, its electric discharge phenomena mainly occur between the two discharge rings, the discharge that lags behind has prolonged the direct acting time of electric spark relatively, promptly at a firing pulse in the cycle, this spark plug produces discharge process twice, significantly make the burning of burning mixture in the cylinder thoroughly abundant, not only saved fuel oil relatively, also make the less carbon distribution of this spark plug.According to the long period evidence, this spark plug have igniting powerful, save fuel oil, strengthen the characteristics that CO and other oxious component obviously reduce in power and the exhaust emissions.
In sum, the utility model is compared with existing spark plug and is had obvious increase electric spark direct effect model Enclose and prolong the electric spark remarkable advantage of action time.
