Pirelli tire model specifications are marked on both sides of the outer tire, which can indicate whether they are run-flat. Run-flat tires, also known as air loss-resistant tires, will have the RSC (Run-Flat System Component) marking on the tire sidewall. Each brand uses different English abbreviations to denote run-flat tires, such as Pirelli's EUFORI for its run-flat models. The technical name for run-flat tires is 'deflation-resistant tires,' abbreviated as RSC in English. The inflated tire sidewall is the primary component supporting the vehicle's weight, especially for tires with a larger aspect ratio where the sidewall is very thick. In severe cases of a tire blowout, the sidewall may collapse instantly, causing the tire to lose support abruptly and leading to an immediate shift in the vehicle's center of gravity. This is particularly dangerous for front-wheel-drive vehicles experiencing a front tire blowout, as the sudden shift in the center of gravity can easily result in loss of control. The run-flat tire system consists of an outer tire, a standard inner tube, a spare inner tube, a steel rim, a gas generator, a pressure sensor, and a control unit.

How many liters of oil does the Buick Excelle 1.3t need?

Buick Excelle 1.3t requires 4.5L of oil, and it should not exceed 5L. Here is some extended information about the Buick Excelle 1.3t: 1. The Buick Excelle 1.3T+48V mild hybrid technology further reduces fuel consumption, requiring only 5.3L per 100 kilometers, which is nearly 9% lower than the previous model. During operation, the engine automatically performs a series of tasks such as agile starting, electric assistance, smart charging, energy recovery, and electric idling based on working conditions and the driver's behavior. This not only reduces fuel consumption but also improves the responsiveness of the power. 2. When starting the vehicle or restarting after an automatic stop, the 48V motor can provide sufficient torque to quickly start the engine to the target idle state with minimal vibration, achieving a smooth and agile engine start and ensuring a comfortable journey for passengers.

Do Children Count as Overloading?

According to traffic regulations, regardless of age, children are considered as overloading. For passenger vehicles other than commercial vehicles (excluding buses) and school buses, overloading by less than 20% will result in a 3-point penalty; overloading by more than 20% will result in a 6-point penalty. The dangers of vehicle overloading include the following three points: 1. Overloading affects the vehicle's suspension and tires, reducing braking performance. 2. Overloaded passengers cannot wear seat belts, and in the event of an accident, the consequences could be severe. 3. Children held in adults' arms are at even greater risk; in a collision, the child could be thrown out due to inertia, causing multiple injuries.

How to Solve ABS Automatic Lock-Up?

Solutions for ABS automatic lock-up: 1. ABS lock-up may be caused by factors such as a stuck brake master cylinder cup that fails to return, insufficient rigidity of the brake disc, improper fit of the brake pads, or poor coordination of internal components in the rear brake. 2. ABS (Anti-lock Braking System) is used in vehicles to prevent loss of control and generally reduces braking distance to enhance vehicle safety. Installing an ABS system in a vehicle helps avoid directional loss and wheel skidding during emergency braking, preventing the wheels from locking up. This ensures that the tires do not rub against the ground at a single point, thereby increasing friction and achieving a braking efficiency of over 90%. Additionally, it reduces brake wear and extends the service life of brake drums, discs, and tires by up to twice as long. 3. Based on speed signals from each wheel speed sensor, the ABS quickly determines if a wheel is locking up. It then closes the normally open input solenoid valve for the locking wheel to maintain braking force. If the wheel continues to lock, the normally closed output solenoid valve is opened, allowing the brake pressure on that wheel to rapidly decrease due to the direct connection to the brake fluid reservoir. This prevents the wheel from completely locking up due to excessive braking force.

How to Read NGK Spark Plug Model Numbers?

The model number of a spark plug is generally arranged in the order of "material", "size", "heat range", "insulation characteristics", "resistance", "electrode shape", and "gap". Taking DENSO's IW16EXRU11 as an example, here is a detailed breakdown: 1. I: Represents the material is iridium, W: Indicates the spark plug diameter is 14mm, 16: Heat range is level 3; 2. E: Represents the thread length is 19-20mm, X: Insulation characteristic is super insulation material, R: Has resistance, U: Ignition electrode structure features a U-shaped groove, 11: Spark plug gap is 11mm.

What Causes High Carbon Monoxide in Exhaust?

There are several main reasons for high carbon monoxide levels in vehicle exhaust: 1. Sensor malfunction: Faulty sensors that control and stabilize the air-fuel ratio can cause excessive gasoline injection, resulting in insufficient air for combustion. This leads to incomplete combustion of gasoline, increasing carbon monoxide levels in the exhaust. 2. Clogged or dirty catalytic converter: This can impair the converter's ability to transform carbon monoxide, requiring cleaning or replacement of the catalytic converter. 3. Excessive carbon buildup: Simply cleaning the carbon deposits to ensure complete fuel combustion and prevent carbon buildup in the engine can significantly reduce carbon monoxide levels in the exhaust.

How much over the speed limit is driving at 80 in a 60 zone?

The formula for calculating the percentage of speeding is: [(Actual speed - Speed limit) / Speed limit] X% = Percentage of speeding. Driving at 80 in a 60 zone and being caught by mobile speed detection constitutes a 40% speeding violation, which results in a fine of 200 yuan and 3 demerit points. On roads other than highways, the levels of speeding and corresponding fines are as follows: 1. Speeding up to 50% over the limit: 3 demerit points and a 200 yuan fine. 2. Speeding between 50% and 80% over the limit: 6 demerit points and a 200 yuan fine. 3. Speeding between 80% and 100% over the limit: 12 demerit points and a 500 yuan fine. 4. Speeding over 100% of the limit: A 1000 yuan fine and possible license revocation.
