Definitions

the invention relates to a spark plug according to the preamble of claim 1.
the object of the invention is therefore to provide a spark plug To provide their cold start properties essential are improved, and in which the previously described Problems with soot can be significantly reduced.
the object of the invention is characterized by the Features of claim 1 solved.
FIG. 1 shows an embodiment a spark plug according to the invention schematically and in partial longitudinal section again;
Figure 2 is a partial cross section through the combustion chamber Area of the insulator base of the spark plug version according to FIG. 1.
the embodiment of the spark plug according to the invention 1 has an electrically insulating ceramic insulator 1, a metallic spark plug body 2, a ground electrode 3 and a center electrode 4, which is centric is arranged in a bore 5 of the ceramic insulator 1.
the center electrode 4 is electrically conductive Sealing compound 6, preferably a glass melt in the Insulator hole 5 fixed.
the Center electrode 4 is a jacket made of a nickel alloy 7 with a core 8 made of a good heat-conducting material, preferably Copper, on.
combustion chamber side Area of the center electrode 4 is tapered
this area is not tapered, but the surrounding area of the Insulator bore 5 has a larger diameter than the connection side Has bore area.
the center electrode 4 with a noble metal reinforcement is preferred 9 provided; it essentially has one corresponding to the diameter of the center electrode tip Diameter from about 0.5 mm to about 1.5 mm and exists preferably made of a platinum alloy or an iridium alloy.
the gap S between Insulator foot 11 and bore diameter of the breathing space 12 of the spark plug body 2 has a width that is at least 1.5 times the ignition gap Z between the ground electrode 3 and center electrode 4 corresponds.
the center electrode 4 is geometrical designed and defined in this way in the insulator bore 5 placed that on the spark plug in extreme cold start operation or when operating the engine with an oxygen / fuel ratio ⁇ ⁇ 1.0 no shunt on the insulation gap of the insulator foot between the center electrode 4 and the spark plug body 2, which is ⁇ 100 MOhm.
Center electrode 4 with around the circumference of the center electrode jacket 7 trending sharp tip 10 becomes local Field peak increase caused, in connection with the sooty insulator foot creates a strong inhomogeneous field, which in turn is a prerequisite for the training of Partial discharges, so-called corona discharges. While engine operation occurs before the electrical breakthrough on the spark gap between the center electrode 4 and the Ground electrode 3 targeted pre-discharges between the sharp ones Tip 10 on the center electrode and the insulator hole 5.
a corona discharge is a Gap between the sharp tip 10 of the center electrode 4 and the insulator bore 5 of at least about 0.15 mm. Due to the constructively initiated pre-discharge it to a stable glow discharge.
the glow discharge growing discharge channels with tufted, bluish discharge pattern clean the insulator bore 5 and interrupt the electrical conductor tape with soot particles coated insulator base 11 to the ground potential of the spark plug body 2nd
the spark plugs of the invention have excellent Cold start and high resistance to Soot with the resulting malfunctions on.
the high shunt resistance of the combustion chamber Conductive path prevents parasitic discharge through the Insulator foot and leads to the best possible ignition of the Air / fuel mixture.
