Spark plug for internal combustion engine

Abstract

The invention discloses a spark plug for an internal combustion engine. The spark plug comprises a fixed pedestal; and a conveying trough extending left and right is formed in the middle part of the upper end surface of the fixed pedestal. A storage box is arranged above the fixed pedestal; and storage space with the upward opening is formed inside the storage box. The right end of a rotating shaft passes through the front end wall of power space and is fixedly connected with the right end wall of the storage space in a rotating manner; and a spiral stirring plate is fixedly arranged at the shaft body, in the storage space, of the rotating shaft. A filling device is fixedly arranged at the left end of the lower end surface of the storage box. According to the invention, dividing plates divide division space into different areas and each area has the same size, so that glass powder adding amounts are equal and thus the processing is controlled effective and high-efficiency and quantitative filling of the glass powder is completed; and thus the work is completed cooperatively and the production cost is saved effectively.

Description

technical field [0001] The invention relates to the field of machining, in particular to a spark plug for an internal combustion engine. Background technique [0002] As a gasoline engine ignition system, the spark plug introduces high-voltage current into the cylinder to generate electric sparks to ignite the combustible gas mixture. The type spark plug requires a certain resistance value between the center electrode and the terminal metal parts, so that it can effectively suppress the high-frequency vibration generated by the spark plug in the vehicle ignition system and the electromagnetic interference generated by these vibrations. The current spark plugs are all in A resistor body is set between the center electrode and the terminal metal parts, and the resistor body is sintered with glass powder. The resistor is a built-in type, which resists radio interference and ensures stable ignition conditions. However, most of the existing powder filling is manually filled. The...

[0002] As a gasoline engine ignition system, the spark plug introduces high-voltage current into the cylinder to generate electric sparks to ignite the combustible gas mixture. The type spark plug requires a certain resistance value between the center electrode and the terminal metal parts, so that it can effectively suppress the high-frequency vibration generated by the spark plug in the vehicle ignition system and the electromagnetic interference generated by these vibrations. The current spark plugs are all in A resistor body is set between the center electrode and the terminal metal parts, and the resistor body is sintered with glass powder. The resistor is a built-in type, which resists radio interference and ensures stable ignition conditions. However, most of the existing powder filling is manually filled. There are certain harmful substances in the glass powder, which will cause serious damage to the human body under long-term work, and the volume of the artificially filled glass powder is difficult to control, which makes the quality of the spark plugs uneven
