Abstract

The invention provides a discharging sparking plug, and particularly relates to a series clearance multi-point discharging sparking plug which is used for a spark-ignition engine. The series clearance multi-point discharging sparking plug comprises a wiring screw, wherein the wiring screw is placed in an insulator; the insulator is riveted in the shell; a central electrode is arranged in a tip of the insulator; a built-in damping resistor is arranged between the central electrode and the wiring screw; a ceramic multi-point discharging ignition table which is connected with the insulator in a matched manner is arranged on the bottom of the insulator; a cavity subassembly is formed between the ceramic multi-point discharging ignition table and the insulator; the outer wall of the upper end of the ceramic multi-point discharging ignition table is fastened to the shell; and an ignition electrode subassembly is arranged on the bottom of the ceramic multi-point discharging ignition table. By the series clearance multi-point discharging sparking plug, the temperature and the pressure of mixed gas are increased during ignition, the ignition performance is improved, and combustion duration is shortened, and the performance of the engine is improved.

Description

technical field [0001] The invention relates to a discharge spark plug, in particular to a serial gap multi-point discharge spark plug for an ignition engine. Background technique [0002] At present, most of the spark plugs used in ignition engines fueled by gasoline, gas, alcohol, etc. generally include insulators, housing sealing It is connected with the wiring screw as the positive electrode of the ignition; the side electrode of nickel alloy material is welded on the shell, and it is used as the ground electrode after being installed with the engine, and the center electrode and the side electrode form a hook-shaped flashover gap. Under the command of the system (ECU), the high-voltage ignition coil is controlled to generate pulsed high-voltage electric energy, which is sent to the spark plug connecting screw through the high-voltage wire (the independent high-voltage coil directly adds the high-voltage positive pole to the connecting screw), and the pulsed high voltag...
