The composition and principle of spark plugs for Petrol Car accessories

The Petrol Car spark plug consists of two parts: an insulator and a metal shell: the metal shell is threaded and screwed into the metal shell on which the cylinder depends; the insulator is installed inside the shell, and inside it, a center electrode runs through, and there is a connection at the upper end of the center electrode Nut, connected to the high-voltage wire coming from the distribution board; welded to the ground electrode on the lower surface of the casing. There is a 0.6-1.0mm gap between the middle electrode and the ground electrode. When high-voltage electricity enters the ground through this gap, sparks will erupt. Ignite the mixture.

The high voltage generated by the ignition device is applied between the center electrode and the side electrode of the spark plug of a Petrol Car, ionizing the gas between the two, thereby destroying the insulation state between the electrodes, thereby generating current, and the discharge generates an electric spark. Electric spark ignition is through the spark discharge between electrodes, which activates the combustion particles and produces a thermal effect to form a flame core, which eventually expands to the surroundings with its own combustion as the center to form a flame.
Installing a rain shield above the car window is a protruding rain shield made of synthetic resin or engineering plastic material. In fact, it is attached to the top of the car window, usually a rain shield made of PC material.
The sun screen can effectively prevent rainwater or strong winds from blowing directly into the car and improve ventilation efficiency; when driving in the rain, opening the windows can prevent the windows from fogging.
To install this rain shield, you lower the glass a few centimeters, and when it rains, rainwater will not run into the Geely Car. At the same time, it can also ventilate the car, which many experienced drivers like to use.
Another cool use for this thing is when it's parked in a parking lot. The glass can also drop a little. Not only can the interior of the car be ventilated, but pedestrians next to you will not notice that your car glass is actually not closed tightly. You won't feel dull even if you lie in the car for too long.
