Car spark plugs not being replaced for a long time can lead to the following consequences: 1. Difficulty in ignition, prone to stalling, insufficient power, weak acceleration, increased carbon deposits formation, manifested as lack of vehicle power, slow acceleration when stepping on the gas, and a missing gear in power; 2. Misfire causing cylinder non-operation or cylinder misfire, manifested as engine shaking, engine fault light turning on, and upon careful listening, the exhaust pipe sound is discontinuous with a popping noise; 3. Incomplete combustion leading to unqualified exhaust emissions, causing environmental pollution. Types of spark plugs include: 1. Standard spark plugs; 2. Projected insulator spark plugs; 3. Electrode spark plugs; 4. Seat spark plugs; 5. Pole spark plugs; 6. Surface gap spark plugs.

What is the function of the anti-collision beam?

The function of the anti-collision beam is to absorb and mitigate external impact forces or to protect the front and rear parts of the vehicle body. The anti-collision beam is a U-shaped channel formed by stamping cold-rolled steel plates and is connected to the longitudinal beams of the vehicle frame, serving as the first barrier of passive safety in automobiles. Anti-collision beams are divided into front and rear anti-collision beams. Below is an introduction to the related content: 1. The front anti-collision beam is usually connected to the longitudinal beams of the vehicle body, protecting rear components such as the radiator and reducing damage in minor accidents. The materials are generally steel, fiberglass, or aluminum alloy, with a thickness of 1.5-3mm. In fact, there is usually a layer of foam supporting the outer plastic skin of the front anti-collision beam, primarily serving to protect pedestrians. 2. The rear anti-collision beam is generally thicker than the front beam, around 2-3mm. It is connected to the longitudinal beams under the vehicle chassis, aiming to reduce impact in minor rear-end collisions and protect the thin spare tire rack and rear fenders, among other parts. Without a rear anti-collision beam, even a minor rear-end collision could cause the plastic skin to fail to withstand any impact.

What is the normal range for a car's mileage?

For a new car, the displayed mileage at delivery is considered normal if it falls within the range of 30 to 50 kilometers. Precautions when taking delivery of a new car: 1. Check the vehicle's production date: Cars produced within the last three months are considered new; those older than three months are inventory cars—be cautious of purchasing an inventory car. 2. Verify the vehicle's documentation: Ensure all necessary documents are present, including the vehicle certificate of conformity, the three-service warranty card, the vehicle user manual, and other relevant documents. 3. Inspect the exterior: Look for any unevenness, scratches, marks, dents, or signs of repainting on the body. Also, check the windows, doors, engine hood, and trunk lid for any signs of friction or damage. 4. Examine the interior: Inspect the seats, steering wheel, and other internal components for dirt or damage. Sniff for any unusually strong odors inside the car. 5. Check the lights. 6. Verify the vehicle's mileage: The mileage of a new car should not exceed 50 kilometers; it's best not to purchase a new car with mileage over 50 kilometers.

Where is the Land Rover's cabin air filter located?

Land Rover's cabin air filter is located under the front windshield, covered by the drainage trough, while most vehicle models have the cabin air filter positioned inside the glove compartment in front of the passenger seat. Removing the glove compartment will reveal the cabin air filter inside. Related information is as follows: 1. When a car is driving with the air conditioning on, it draws in external air into the cabin. However, the air contains various particles such as dust, pollen, soot, abrasive particles, ozone, odors, nitrogen oxides, sulfur dioxide, etc. Without the cabin air filter, these particles can enter the cabin, not only contaminating the car's air conditioning system and reducing the cooling system's performance but also causing allergic reactions, lung damage, irritation from ozone, and discomfort from odors, all of which can affect driving safety. 2. Generally, the cabin air filter should be replaced every 10,000-15,000 kilometers, often chosen to be replaced in the spring. This is because after being used through the previous summer and winter, the filter's effectiveness declines. Depending on local weather conditions and usage, if there are frequent sandstorms or haze, or prolonged air conditioning use, the replacement interval can be adjusted appropriately, preferably every 7,500 kilometers.

How Long After Replacing the Windshield Can You Drive?

Since the windshield is secured with glass adhesive, which requires curing time, how soon you can drive depends on the adhesive's hardening time. Once it hardens and fixes the glass in place, the car is ready for use. Some adhesives are quick-drying, hardening and securing the glass in about 1-2 hours, while others may take around 6 hours to cure. Currently, standard adhesives on the market require a curing temperature of approximately 5-40°C, with safe driving achievable after 24 hours. Below are precautions to follow after windshield replacement: 1. Avoid washing the car for three days after replacement, and remove the tape securing the windshield only after this period. 2. Try to avoid driving on excessively bumpy roads, and refrain from sudden braking or rapid acceleration to prevent windshield displacement. 3. Do not insert parking permits or other cards into the gap between the windshield and the dashboard. 4. Avoid highway driving and keep the maximum speed below 80 km/h. 5. Do not apply window tint within seven days. Additionally, avoid opening windows while driving for three days after rear windshield replacement to prevent displacement due to wind pressure.

What is the difference between the internal and external air circulation modes in a car's air conditioning system?

Introduction to the differences between internal and external air circulation modes: 1. Internal circulation mode keeps air circulating only within the vehicle, using the blower to recirculate the cabin air. 2. External circulation mode connects the cabin with the outside environment. While driving, airflow automatically enters the cabin through wind pressure, and when stationary, outside air can still enter through air ducts to the blower and then into the cabin. Below are detailed explanations of both modes: 1. External circulation: Newly purchased vehicles should use external circulation as much as possible to maintain air flow between inside and outside the car, helping to release harmful gases from the cabin. Additionally, during long highway drives, continuous use of internal circulation may lead to oxygen deficiency in the cabin, potentially causing driver fatigue and accidents. In such cases, switching to external circulation helps replenish fresh air. 2. Internal circulation: While daily driving primarily uses internal circulation, it's crucial to activate this mode during traffic jams. Congested areas have higher concentrations of exhaust fumes, and internal circulation effectively prevents external pollutants from entering the cabin. It's also essential to use internal circulation during sandstorms or dusty conditions, as it not only blocks external dust but also reduces the impact of sand on the air filter.
