Problems solved by technology

[0003] At present, the engine factories in the domestic automobile industry and the aftermarket have no means to detect the flashover performance of spark plugs, and product quality problems can only be tested by spark plug manufacturers on professional equipment in the product line. The market is in urgent need of a detection device that can detect the ignition performance of the spark plug by itself

Embodiment 1

[0016] From attached figure 2 and 3 It can be seen that the present invention is a spark plug sparkover and insulator withstand voltage test method and device, a spark plug ignition and spark plug insulator withstand voltage detector, at least including a spark plug detection chamber, the detection chamber is filled when detecting the spark plug A closed chamber with pressure gas, the closed chamber is filled with pressure gas, and a spark plug detection table is installed on the side of the detection chamber, and the spark plug to be tested is installed on the spark plug detection table; at the same time, the tester also includes A three-pin discharger chamber for spark plug detection, a three-pin discharger is installed in the three-pin discharger chamber; and the three-pin discharger and the spark plug under test are provided with the same voltage by the ignition coil of the same ignition system at the same time Pulse high voltage power supply. The spark plug detection c...

Embodiment 2

[0021] The principle of the second embodiment is the same as that of the first embodiment, except that the sealed chamber of the three-pin discharger and the sealed chamber of the spark plug testing station share one closed chamber, that is, the three-pin discharger and the spark plug testing station are placed in the same closed chamber at the same time indoor.

Embodiment 3

[0023] The principle of the third embodiment is the same as that of the second embodiment, except that the three-needle discharger 9 and the sealed chamber 8 of the spark plug detection table are placed in the detection box 1, and there are holes on the detection box 1 for observing the three needles. The discharger 9 and the spark plug detection platform are the observation windows for detecting the discharge of the spark plug 11 .

[0024] The device of the present invention has the following characteristics:

[0025] 1. This tester can fully meet the requirements of GB7825-87 for spark plug flashover performance test to test spark plugs.

[0026] 2. The tester can simulate whether the spark plug can ignite under the high pressure condition of the engine cylinder.

[0027] 3. The ignition voltage of the tester can be adjusted between 0 and 35KV.

[0028] 4. The working air pressure of this tester can be 0~20kgf / cm 2 between adjustments.

[0029] 5. The tester is equipped...

Abstract

Tester for testing ignition capability and voltage resistant capability of sparking plug and testing method and uses, at least including one sparking plug test chamber, which is filled with pressure gas and is closed in testing the sparking plug, the closed chamber is filled with pressure gas, flank of the test chamber is mounted with sparking plug test station for placing being tested sparking plug, the being tested sparking plug is placed on the sparking plug test station; simultaneity the tester also includes three needles electrical discharger chamber for matching sparking plug test; and the three needles electrical discharger and the sparking plug are provided with identical voltage detecting pulse high-voltage power supply by the sparking coil of the same ignition system at the same time. The tester for testing ignition capability and insulator arching capability of the sparking plug, possessing advantages of simple and intuition, and the testing device is mot complicated, which can be widely used in each engine works in domestic automobile industry and aftermarket.

Description

technical field [0001] The invention relates to a spark plug detection instrument and its detection method and application, in particular to a spark plug ignition and insulator withstand voltage performance tester, testing method and application, belonging to testing or analysis by means of chemical or physical properties of materials Materials, International Patent Classification as G01N. Mainly used for spark plug ignition and insulator withstand voltage performance test. Background technique [0002] Spark plugs are widely used in internal combustion engines. The side electrodes of the spark plug are welded to the shell port and the center electrode to form a gap. When the spark plug is working, the current jumps between the electrodes, and a strong hot spark is generated through the high-voltage discharge between the two electrodes, which ignites the compressed gas mixture in the cylinder. Conduct electrical ignition and combustion to generate kinetic energy to propel t...
