High-stability sparking plug

Abstract

The invention discloses a high-stability sparking plug comprising a central electrode. An insulating body sleeves the outside of the central electrode; and a metal housing sleeves the outside of the insulating body. The central electrode and the metal housing are respectively connected with positive and negative electrodes of a power source. A ground electrode is arranged on the metal housing. The central electrode includes a positive discharge tip; and the ground electrode includes a negative discharge tip; and when the positive discharge tip and the negative discharge tip are bend in opposite, a discharging gap is formed. According to the high-stability sparking plug, because the discharge tips are arranged at the positive and negative electrodes and are bent in opposite, a discharge effect is caused easily between electrodes and a strong-spark ignited gas-oil mixture is formed, so that the ignition success rate is increased. The ignition stability of the sparking plug is ensured con the condition of low voltage, so that the ignition effect is improved.

Description

technical field [0001] The invention relates to the field of spark plugs, in particular to a high-stability spark plug. Background technique [0002] The function of the spark plug is to introduce tens of thousands of volts of high voltage into the combustion chamber in the internal combustion engine, rely on the pulse high voltage discharge, the current skips between the electrodes, breaks down the air between the two electrodes of the spark plug, generates a strong thermal electric spark, and ignites the cylinder The mixture of oil and air in the engine generates kinetic energy to propel the engine. The voltage required when the spark plug electrode breaks down to generate sparks is called the breakdown voltage. The secondary voltage generated by the ignition system must be higher than the breakdown voltage to make the spark plug flash, so it is necessary to provide high voltage to the spark plug. [0003] According to the principle of tip discharge, the sharper the tip o...

Problems solved by technology

[0003] According to the principle of tip discharge, the sharper the tip of the conductor, the easier it is to produce a discharge effect. Most of the spark plugs on the market use the center electrode as the tip and the ground electrode as a horizontal plate. During the use of the car, if the voltage is unstable In some cases, the strength of the discharge spark of the spark plug will be affected, and it will directly lead to the decline of the ignition effect.

Especially in the case of low voltage, due to the insufficient energy provided, the spark plug sometimes cannot ignite normally, the ignition performance is unstable, and the success rate of ignition is low, resulting in the car not being able to start smoothly, and even easy to turn off after starting
