If the ETC is correctly activated, it indicates that the signal is normal and can pass through the ETC lane smoothly. Here are the precautions for using ETC: Installation requirements: The ETC device should be installed at a height not lower than 1.2 meters and not higher than 2.5 meters. The installation angle N should be between 30 and 90 degrees (the angle between the surface of the electronic tag and the horizontal plane). Passage requirements: The ETC transaction sensing area is 8 meters, and the recognition speed in the ETC lane should be below 20km/h. To prevent automatic sensing from paying for the vehicle in front, maintain a distance of more than 10 meters from the vehicle ahead. Excessive speed may also lead to payment failure. If the ETC card is underfunded, it may be included in the ETC blacklist, which will be lifted 24 hours after recharge.

Is It Normal for the Bottom of a Spark Plug to Appear Red?

It is normal for the bottom of a spark plug to appear red. The spark plug is a critical component of a gasoline engine's ignition system, which introduces high-voltage electricity into the combustion chamber and causes it to jump across the electrode gap to generate a spark, thereby igniting the combustible air-fuel mixture in the cylinder. It consists of a terminal nut, insulator, terminal stud, center electrode, side electrode, and shell. The principle of the spark plug: Under high voltage, the air between the center electrode and the side electrode rapidly ionizes, forming positively charged ions and negatively charged free electrons. Types of spark plugs: 1. Standard spark plugs; 2. Insulator-protruding spark plugs; 3. Electrode-type spark plugs.
