Should the Protective Film on the Car Dashboard Be Removed?

It is recommended to remove the protective film on the dashboard of a new car, as prolonged adhesion can leave marks. Below is relevant information about the car dashboard: 1. Speedometer and Odometer: The speedometer and odometer are actually composed of two gauges. One is the speedometer, and the other is the odometer. Traditional speedometers are mechanical. A typical mechanical odometer is connected via a flexible shaft, which contains a steel cable. The other end of the flexible shaft connects to a gear in the transmission. The rotation of the gear drives the steel cable to rotate, which in turn rotates a magnet inside the odometer housing. 2. Tachometer: The tachometer is usually located on the instrument panel, placed symmetrically with the speedometer and odometer. The tachometer operates based on magnetic principles, receiving pulse signals generated when the primary current in the ignition coil is interrupted. These signals are then converted into a readable RPM value. The faster the engine speed, the more pulses the ignition coil generates, resulting in a higher RPM reading on the gauge.

What are the standard specifications for defining a salvage vehicle?

Salvage vehicles are defined by the following standard specifications: 1. Strictly speaking, any vehicle that has been involved in an accident, regardless of its severity, is considered a salvage vehicle. 2. However, it typically refers to vehicles that have been involved in major accidents. Minor incidents like small scratches or dents (minor accidents) are not classified as salvage vehicles. A salvage vehicle is one that has sustained damage from non-natural wear and tear accidents, resulting in decreased mechanical performance and economic value. The determination of a salvage vehicle usually falls into two scenarios: 1. Replaceable parts: If the damaged parts of the vehicle can be replaced (e.g., a damaged front bumper, headlight, or front fender), it is considered a minor accident. 2. Non-replaceable parts: If the damaged parts of the vehicle cannot be replaced (e.g., the longitudinal beam, rocker panel, or A/B/C pillars) and can only be repaired through reshaping, cutting, or welding, then it is classified as a severe salvage vehicle.

What are the pros and cons of electronic throttle controllers?

Electronic throttle controllers have the following advantages and disadvantages: 1. Advantages of electronic throttle controllers: Amplify throttle signals to improve static response. The so-called 'acceleration' of electronic throttle controllers is mainly achieved by increasing throttle response sensitivity. 2. Disadvantages of electronic throttle controllers: Increased fuel consumption. Since the throttle controller enhances throttle response, it effectively makes the driving style more 'aggressive,' which undoubtedly increases fuel consumption. However, the increase in fuel consumption is not very significant. Increased driving difficulty. Once an electronic throttle controller is installed, regardless of the current road conditions, the driver will faithfully execute the 'acceleration' intention, which invisibly places higher demands on driving skills. During nighttime driving with poor visibility or in rainy/snowy weather when the road is slippery, excessive acceleration increases driving hazards.

What kind of engine oil is best for the first maintenance of a new car?

It is recommended to use the original engine oil for the first maintenance of a new car. Here is some relevant knowledge about car maintenance: 1. First maintenance knowledge: As long as the new car is taken to the 4S shop for the first maintenance within the specified period, even if the subsequent maintenance is not done at the 4S shop, the three guarantees can still be enjoyed. However, if the user purchases a new car and does not go to the designated 4S shop or the manufacturer's designated authorized repair shop for the first maintenance within the specified mileage, if there is a problem with the car, even during the warranty period, the user will have to pay a certain amount of repair costs. 2. Engine oil selection: Whether you choose the engine oil yourself or use the free engine oil provided by the 4S shop, you should first confirm the engine type and model. If you are not satisfied with the free engine oil provided by the 4S shop, you can completely purchase brand engine oil yourself or add some money to purchase the original synthetic engine oil from the 4S shop.

What are the requirements for spark plug gap standards?

The standard requirement for spark plug gap is between 0.8-0.9mm. Methods to determine if a spark plug is damaged: Remove the spark plug and observe its condition based on the following appearance colors. A normal spark plug will have its insulator skirt and electrodes appearing gray-white, gray-yellow, or light brown. A properly functioning spark plug will have a reddish-brown insulator skirt, an electrode gap between 0.8-0.9mm, and no signs of electrode burn. If the spark plug has oil stains or deposits but is not damaged, it can continue to be used after cleaning off the oil and deposits. If the spark plug is severely damaged, with signs such as blistering at the top, black streaks, cracks, or melted electrodes, the cause of the damage should be identified. After troubleshooting, replace the spark plug with a new one. Additionally, if the spark plug appears black as if smoked, it indicates that the wrong heat range was selected or the air-fuel mixture is too rich, with oil creeping up.

Does a new car need an annual inspection after one year?

Whether a new car that has just reached one year needs an annual inspection depends on the vehicle model and its specific nature. Below is relevant information about the annual inspection: 1. Conditions: Vehicles whose condition does not match the records on the driving license or registration file, or whose license plates or driving licenses are damaged, incomplete, illegible, or self-made. 2. Notes: The exterior of the vehicle cannot be modified. The color of window sunshade or anti-explosion film cannot be too dark (items inside the vehicle should be clearly visible from one meter away; mainly applies to vans and trucks, but not to small cars with fewer than 5 seats). Vans and trucks must have enlarged rear license plates, and the number of spring leaf plates cannot be increased or decreased. The number of seats in a van cannot be altered, and a fire extinguisher must be present. The cargo compartment of a box truck cannot be modified (no side doors, no roof openings, and no tailgates can be added). The size of the tires cannot be altered, and the tread patterns on tires of the same axle must be consistent. Vehicles with unresolved traffic violations or those impounded by the court cannot undergo an annual inspection.
