Description

Technical Field

[0001] This utility model relates to the field of spark plug technology, and in particular to an environmentally friendly spark plug for exhaust emissions. Background Technology

[0002] Spark plugs are key components in internal combustion engines used to ignite the air-fuel mixture. The working principle and performance of spark plugs directly affect engine starting, power, fuel efficiency, and emissions.

[0003] Existing spark plugs ignite fuel in the engine by generating current through the bottom electrode. However, due to the lack of current concentration, the ignition effect is insufficient, leading to incomplete combustion of the air-fuel mixture and increased exhaust emissions. Furthermore, because their insulating sleeves are made of ceramic, if the sleeve is damaged, the entire spark plug must be replaced, rather than individual sleeves, resulting in poor environmental performance. Therefore, this solution proposes an environmentally friendly spark plug to address the aforementioned problems. Utility Model Content

When the insulating sleeve 8 is fitted onto the outer wall of the spark plug body 1, pushing the insulating sleeve 8 causes the retaining ring 9 to move, moving the retaining ring 9 into the first fixing frame 6 and inserting it into the limiting block 11. The limiting block 11 restricts the retaining ring 9, preventing it from rotating within the first fixing frame 6 and improving stability. If the insulating sleeve 8 is damaged, it can be removed from the spark plug body 1 for replacement, thus extending the service life of the spark plug body 1 and improving environmental friendliness.

The roller 13 secures the fixing ring 9, preventing it from moving. If the insulating sleeve 8 is damaged, the second fixing frame 7 is rotated to separate it from the mounting ring 10. The movement of the second fixing frame 7 then moves the push rod 14, which in turn moves the pusher 12. The movement of the pusher 12 then moves the roller 13, separating it from the fixing ring 9. The insulating sleeve 8 can then be removed from the spark plug body 1 for replacement, improving the lifespan of the spark plug body 1 and enhancing environmental friendliness.
