What is the replacement interval for spark plugs in household vehicles?

Household vehicle spark plug replacement intervals: 1. The lifespan of standard spark plugs is 20,000 kilometers. They can typically continue to be used beyond this mileage, but it is recommended not to exceed 40,000 kilometers, otherwise the ignition efficiency will decrease, leading to reduced engine power; 2. Single platinum spark plugs have a lifespan of 50,000 to 80,000 kilometers and require regular replacement; 3. Iridium spark plugs last for 50,000 kilometers. When performance declines, it manifests as cathode erosion, causing changes in ignition gap and reduced stability, so regular replacement is advised. Spark plugs utilize high-voltage discharge to break down the air between electrodes, generating an electric spark to ignite the combustible gas mixture in the combustion chamber, thereby maintaining engine operation. The main types of spark plugs include: standard spark plugs, insulator projection spark plugs, electrode spark plugs, seat-type spark plugs, and pole-type spark plugs.

Should You Pull Out a Nail Stuck in a Tire?

If a nail gets stuck in your tire, it is recommended not to pull it out by yourself. Since the tire is in a rolling state while driving, the nail may not be inserted vertically. If you remove it without timely repair, the tire may become irreparable. The tire must be removed from the rim and inspected by a professional tire dealer to determine if it can be repaired. Tire maintenance methods: 1. Regularly clean out small stones stuck in the tire treads and avoid prolonged exposure to sunlight; 2. Frequently check the tire pressure—the normal values are indicated on the inner side of the fuel tank cap, so adjust accordingly; 3. Pay attention to suspension maintenance and periodically check the front wheel alignment.

What are the causes of high-speed body vibration?

High-speed body vibration is caused by: 1. Uneven brake disc surface; 2. Large deviation in wheel alignment data, especially incorrect front wheel alignment angles and excessive toe-in; 3. Tire pressure being too high or too low - higher speeds with overinflated tires cause more severe body vibration, while underinflated tires result in floating sensation and pulling; 4. Abnormal tire wear; 5. Rim deformation - when tires are mounted on deformed rims, the tires also deform, leading to uneven surfaces and incorrect wheel dynamic balance, causing vibration during driving; 6. Damaged shock absorbers - at high speeds, the impact from the road surface to the tires is transmitted to the body without attenuation, causing vibration throughout the entire vehicle.

What is the principle of a reversing camera?

The principle of a reversing camera: Through the wide-angle infrared camera device at the rear of the vehicle, the road conditions behind are displayed on the in-car screen. Combined with radar and screen guide lines, it makes parking more convenient and safer. The reversing camera system is a safety auxiliary device for car parking or reversing, which can inform the driver of the surrounding obstacles through image display, eliminating the troubles caused by the driver's need to look around during parking, reversing, and starting the vehicle, thereby improving driving safety. After years of development, the reversing camera system has upgraded its technology, improved its performance, and been applied to various vehicle models, such as trucks, buses, combine harvesters, coaches, and construction machinery, among other large vehicles.

What does 'dynamic' mean when it appears in an Audi?

Audi's 'dynamic' refers to the car being in dynamic steering mode. In this mode, the throttle is more responsive, the steering becomes heavier, and the characteristic is that the engine reaches higher RPMs before shifting gears. Audi's dynamic mode also features Audi's unique dynamic steering system and Audi's damping suspension control system. Audi cars are symbolized by four interlocking rings. The automotive brands under Audi include Lamborghini, Audi, and Ducati. Taking the Audi S4 as an example: it is a mid-size car under Audi, with a length, width, and height of 4770mm, 1847mm, and 1404mm respectively, a wheelbase of 2825mm, a front-engine four-wheel-drive layout, front and rear five-link independent suspensions, and an 8-speed automatic transmission. It is a four-door, five-seater sedan.

How to Measure Engine Oil Pressure?

The method for measuring engine oil pressure is as follows: 1. Disconnect the wiring harness plug of the oil pressure sensor and remove the oil pressure sensor; 2. Screw the hose connector of the oil pressure gauge into the bolt hole where the oil sensor is installed and tighten the connector; 3. Place the oil pressure gauge in a location where it will not come into contact with rotating or high-temperature engine components; 4. Start the engine and allow it to reach normal operating temperature, then compare the reading with the standard value. The reasons for excessively high oil pressure include: 1. Excessive oil viscosity; 2. Improper adjustment of the pressure relief valve; 3. Malfunction of the oil pressure gauge or sensor. The functions of engine oil are: lubrication and anti-wear, auxiliary cooling, cleaning, sealing to prevent leaks, rust and corrosion prevention, and shock absorption.
