What are the indicators of gasoline?

Gasoline's main indicators include octane number, gum content, distillation range, vapor pressure, sulfur content, etc. 1. Volatility: Refers to the ease with which gasoline evaporates in the carburetor. It has a significant impact on engine starting, warm-up, acceleration, vapor lock, and fuel consumption. The volatility of gasoline is comprehensively evaluated by three indicators: distillation range, vapor pressure, and vapor-liquid ratio. 2. Anti-knock performance: Refers to the ability of gasoline to resist detonation combustion under various operating conditions. The anti-knock performance of automotive gasoline is expressed by the octane number. The higher the octane number, the better the anti-knock performance. The anti-knock capability of gasoline is related to its chemical composition. 3. Stability: Refers to the stability of gasoline when stored for a long time under natural conditions. It is characterized by gum content, induction period, and iodine value. The lower the gum content, the better; the longer the induction period, the better. National standards stipulate that the actual gum content per 100 milliliters of gasoline must not exceed 5 milligrams. The iodine value indicates the content of olefins.

Why is my car's fuel consumption getting higher and higher?

The reasons for increasing car fuel consumption are as follows: Dirty engine oil: When engine oil becomes dirty, it leads to poor lubrication, increasing resistance in various moving parts of the engine. More energy is required to overcome this resistance, resulting in higher fuel consumption. Dirty air filter: A dirty air filter causes poor air intake. Firstly, more energy is consumed during air intake. Secondly, insufficient air intake leads to incomplete combustion, where some gasoline isn't fully burned and gets expelled. Naturally, more gasoline is required to travel the same distance. Spark plugs reaching end of life: Spark plugs are often overlooked, with some people not replacing them even after 100,000 kilometers. Although spark plugs can still function after their lifespan, insufficient ignition energy causes delayed ignition, missing the optimal ignition timing. This also leads to incomplete combustion, further increasing fuel consumption. Excessive carbon buildup in the vehicle: Carbon deposits typically accumulate in the throttle body, fuel injectors, intake manifold, and piston tops. Excessive carbon buildup in any of these areas will cause incomplete combustion, thereby increasing fuel consumption.

How to Explain the Functions of the X-Trail's Center Console Buttons?

Center console buttons: 1. Electronic Stability Program (ESP): Enabled by default, it is generally not recommended for the driver to manually turn it off. This system effectively prevents vehicle loss of control during extreme driving conditions. 2. Parking Radar/Image: The center display shows the reverse image, and the radar will sound an alarm when detecting nearby obstacles. 3. Internal/External Air Circulation: Internal circulation means the air inside the car is sealed and recirculated, while external circulation exchanges air between the inside and outside of the car. Use internal circulation in congested areas or environments with poor air quality. On highways, switch to external circulation approximately every hour to refresh the air inside the car and prevent oxygen deprivation. 4. Temperature Zone Synchronization: When this function is enabled, changing the temperature in the driver's area will automatically adjust the other zones to the same setting. Disabling this function allows each zone to be set individually to meet the needs of passengers in different locations. 5. Auto Hold: At a red light, this feature relieves foot fatigue by automatically locking the wheels with the brake calipers. Pressing the accelerator again will allow the vehicle to move forward. 6. Auto Start-Stop: During brief stops, the engine will shut off. The vehicle will restart when the driver's foot leaves the brake pedal.

Is the Compulsory Insurance Label Still Required to Be Displayed on the Vehicle in 2021?

If electronic insurance policies have been implemented in your area, the compulsory traffic insurance label does not need to be displayed. Additionally, the annual inspection label was fully digitized in 2020 and replaced by an electronic inspection certificate, so the annual inspection label no longer needs to be displayed either. How to Use the Electronic Inspection Certificate: If stopped by traffic police, you can present the electronic inspection certificate via the Traffic Management 12123 app. The specific steps are as follows: Open the Traffic Management 12123 app, log in with your account credentials; after entering the homepage, click on the "Motor Vehicle" function in the top left corner; once in the motor vehicle function interface, locate the "Electronic Inspection Certificate" and click to open it, which will generate a QR code. Notes on Using the Electronic Inspection Certificate: If you lend your car to a friend and they are stopped by traffic police, the electronic inspection certificate can still be used. It can be forwarded to your friend for use or printed on an A4 sheet of paper to be presented during a traffic police check.

What Are the Practical Parallel Parking Techniques?

Practical parallel parking techniques: Master the timing of three key actions - when to turn the steering wheel to the right, when to straighten the wheels, and when to turn the steering wheel to the left. Steps for parallel parking: First, adjust the car's position and look at the right rearview mirror. When the right rear tire is parallel with the curb line, immediately turn the steering wheel all the way to the right and reverse. Observe the left rearview mirror, and when corner C of the parking space appears, straighten the wheels. Continue observing the left rearview mirror, and when the left rear wheel crosses the curb line, turn the steering wheel all the way to the left. When both sides of the car body are parallel with the curb line, straighten the wheels. Precautions for parallel parking: During parallel parking, it's crucial to pay attention to the distance. If the car is parked too far from the parking space when reversing, the angle of deviation will be too large, making it difficult to straighten the car even if the rear wheels can enter the space. If the car is parked too close to the parking space when reversing, the right front corner of the car will be very close to the car in front, increasing the risk of a scrape when straightening the wheels, and the rear of the car becomes a potential hazard point if the right front corner is avoided.

What is the maximum service life of a car?

China's vehicle retirement standards based on service life are as follows: 1. Towing trucks, mining special-purpose vehicles, mini trucks, and all types of taxis have an 8-year service life. Upon reaching the retirement period, their use cannot be extended. 2. Non-operational passenger vehicles with 9 seats or fewer (including sedans and off-road vehicles) have a 15-year service life. After meeting retirement standards, continued use is permitted without approval, subject to passing inspections. Such vehicles require 2 annual inspections, and those exceeding 20 years require 4 annual inspections starting from the 21st year. 3. Light, medium, and heavy-duty trucks, tourist passenger vehicles, and non-operational passenger vehicles with more than 9 seats have a 10-year service life. Continued use after meeting retirement standards requires approval procedures, with a maximum extension of 10 years. Tourist passenger vehicles require 4 annual inspections. Non-operational passenger vehicles with more than 9 seats require 2 annual inspections, increasing to 4 annual inspections starting from the 16th year for vehicles exceeding 15 years. 4. The service life of operational buses is adjusted to 10 years. Continued use after meeting retirement standards requires approval procedures, with a maximum extension of 4 years, during which 4 annual inspections are required.
