Automobile engine spark plug with adjusting function

Abstract

The invention relates to the technical field of spark plugs, in particular to an automobile engine spark plug with an adjusting function, which comprises a plug body, a protective shell is fixedly connected to the surface of the plug body, a hydraulic bin is slidably connected to the surface of a sealing sliding plate, and a reset spring is fixedly connected to the bottom end of the sealing sliding plate. A line adjusting device is arranged at the top of the sealing sliding plate, a cooling liquid bin is fixedly connected to the surface of the hydraulic bin, a cooling stirring device is arranged at the top end of the cooling liquid bin, and a liquid inlet valve and a liquid outlet valve are fixedly connected to the interior of the hydraulic bin. A liquid inlet valve and a liquid outlet valve are controlled to feed and discharge liquid into and out of a hydraulic bin, cooling liquid flows into the hydraulic bin from a cooling liquid bin, hydraulic pressure is utilized to pressurize a sealing sliding plate when the cooling liquid is injected, the sealing sliding plate drives a protective shell and a sealing rod to integrally move downwards after being stressed, and the effect of downwards adjusting a plug body is achieved in the moving period; the plug body can be conveniently adjusted up and down.

Description

technical field [0001] The invention relates to the technical field of spark plugs, in particular to an automobile engine spark plug with an adjustment function. Background technique [0002] The spark plug is an important component of the gasoline engine ignition system. It can introduce high-voltage electricity into the combustion chamber and make it jump over the electrode gap to generate sparks, thereby igniting the combustible mixture in the cylinder. It is mainly composed of a wiring nut, an insulator, a wiring screw, a center electrode, a side electrode and a shell, and the side electrode is welded on the shell. [0003] At this stage, the gap of the spark plug often needs to be adjusted according to different requirements. The existing device often damages the ceramic body of the spark plug during the adjustment process. The adjustment process is often performed manually, and the gap distance cannot be adjusted finely. The motor may be damaged by excessive force. I...
