What does the EP switch on a truck mean?

EP switch on a truck refers to the Electronic Parking Brake system, abbreviated as EPB. EPB utilizes the longitudinal acceleration sensor in the vehicle's computer to calculate the slope ratio, thereby determining the downhill force caused by gravity when the vehicle is on an incline. Below is an introduction to EPB: Function of EPB: EPB, also known as the Electronic Parking Brake system, is an upgrade from the traditional parking brake. While the original parking brake operates mechanically, the electronic parking brake functions electronically, offering great convenience in use. Advantages of EPB: The EPB system can automatically apply the parking brake after the engine is turned off, providing convenient and reliable parking while preventing accidental release. It replaces the traditional mechanical handbrake with more advanced electronic control technology, avoiding safety hazards such as forgetting to engage the handbrake when parking or forgetting to release it when starting. It can also serve as a braking system in emergency situations.

Is a 55W LED car light bright enough?

Relatively bright. High beams are generally 40-60W, while low beams are typically 35-55W. Here are detailed introductions about LED lights: 1. Introduction: LED car lights refer to car lights that use LED (Light Emitting Diode) as the light source. Because LEDs have the characteristics of high brightness, rich color variety, low power consumption, and long lifespan, they are widely used in the automotive field. 2. Types of car lights: Car headlights mainly include halogen, xenon, and LED. Among them, low- to mid-range cars mainly use halogen headlights, xenon headlights are common in some mid- to high-end vehicles, while LED headlights are only used in a very few new vehicles. Due to the fast volatilization speed of halogen headlights, their brightness decreases over time until they burn out. The designed lifespan is generally 2-3 years. Xenon lights typically last about twice as long, up to 5-6 years. As for LED lights, their lifespan is quite long and can easily last until the car is scrapped.

What Maintenance Does a Car Need at 20,000 Kilometers?

After a car has traveled 20,000 kilometers, the maintenance items include: changing the engine oil, oil filter, fuel filter, air filter, and cabin air filter. Below is an introduction to car maintenance taboos: 1. Avoid running the engine for long periods in an unventilated garage. The exhaust gas from the engine contains carbon monoxide, an invisible and odorless toxic gas. Even when working outdoors, avoid staying near the exhaust pipe of a running engine for extended periods. 2. Avoid sucking oil pipes with your mouth. Gasoline is not only flammable and explosive but also toxic. Especially leaded gasoline can damage the nervous system, digestive tract, and kidneys. Additionally, gasoline contains high concentrations of sulfides, as hydrogen sulfide is also toxic. Ingesting gasoline can lead to poisoning or death. If ingested, induce vomiting and seek medical treatment immediately. 3. Avoid contact with carburetor cleaner. Most carburetor cleaners contain methyl chloride, aromatic compounds, and ethanol, all of which are toxic. Therefore, inhaling these substances or getting them on the skin and eyes is very dangerous.

Does the fire brigade not issue a certificate for vehicle spontaneous combustion?

There is no regulation requiring the fire brigade to issue a certificate for vehicle spontaneous combustion. Here are the details: 1. Precautions: In reality, there is indeed such a demand, but there is no regulation stating that the fire brigade must issue a certificate. If it is for insurance purposes, it is essential to request the fire brigade to issue a fire incident report, which is the correct approach. 2. Causes of spontaneous combustion: Installing electrical appliances or modifying wiring in a vehicle, due to installer errors or rough construction, can cause short circuits in the wiring, leading to a fire. Aging of vehicle electrical components and wiring, combined with the user's neglect of inspection and maintenance, can also easily result in short circuits and fires. Aging of engine fuel lines and improper replacement of parts like fuel pipes can cause fuel leaks. When encountering short circuits in wiring or aging electrical components producing open flames, it is easy to ignite gasoline, causing a fire. New cars catching fire due to quality issues are considered extremely rare occurrences. With the continuous improvement in manufacturing standards, such fire incidents are becoming increasingly rare.

What is the working principle of a gasoline engine spark plug?

The working principle of a gasoline engine spark plug: The spark plug's ground electrode is connected to the metal shell, which is threaded into the engine block via the cylinder head. The insulator primarily serves to isolate the metal shell from the center electrode. The terminal nut is the part of the spark plug that contacts the high-voltage coil. When current passes through the terminal nut and the center electrode, it ionizes the medium between the center electrode and the ground electrode, generating a spark to ignite the air-fuel mixture in the cylinder. Spark plugs are installed on the side or top of the engine. Early spark plugs were connected to the distributor via ignition wires, but in the past decade, most car engines have switched to direct connection between the ignition coil and the spark plug. If a spark plug is damaged, it can directly cause issues such as ignition system leakage, increased fuel consumption, and reduced power. The most significant problem is difficulty in ignition, affecting the vehicle's normal operation. Severe spark plug erosion, including scarring at the top, damage, or melted and eroded electrodes, indicates that the spark plug is damaged and should be replaced.
