If you have accidentally filled up with poor-quality fuel, here are the solutions: 1. If the vehicle can currently operate normally, promptly and completely drain the remaining fuel in the tank, refill with high-quality gasoline, clean the fuel injectors and combustion chamber, and replace the fuel filter. 2. If the vehicle can currently operate normally but the engine idles with slight vibrations, completely drain the remaining fuel in the tank, refill with high-quality gasoline, clean the throttle body, fuel injectors, and combustion chamber, and replace the fuel filter. 3. If the engine fails to start, and there is no cylinder pressure upon measurement with severe piston impact marks, completely drain the remaining fuel in the tank, refill with high-quality gasoline, clean the throttle body, fuel injectors, and combustion chamber, and replace both the fuel filter and fuel pump.

How many points will be deducted for resting less than 20 minutes after 4 hours of continuous driving?

Resting less than 20 minutes after 4 hours of continuous driving will result in a deduction of 6 or 12 points. If you drive a medium-sized or larger passenger vehicle or a hazardous materials transport vehicle continuously for more than 4 hours without stopping to rest or resting for less than 20 minutes, 12 points will be deducted at once; if you drive any other motor vehicle (excluding medium-sized or larger passenger vehicles and hazardous materials transport vehicles) continuously for more than 4 hours without stopping to rest or resting for less than 20 minutes, 6 points will be deducted at once. Fatigue driving: Refers to the phenomenon where a driver's physiological and psychological functions become imbalanced after prolonged continuous driving, leading to a decline in driving skills. It affects the driver's attention, thinking, judgment, and other aspects, making it highly likely to cause traffic accidents.

Is there a fine for driving in the wrong direction?

Driving in the wrong direction will certainly result in a fine. Driving against traffic: According to the 'Scoring Standards for Road Traffic Safety Violations', driving against traffic on ordinary roads will result in a 3-point deduction; on highways, it's a 6-point deduction. Driving against traffic can be divided into two situations: one is driving in the wrong direction on a one-way street, and the other is driving against traffic at an intersection. Consequences of driving against traffic: Driving against traffic is a relatively serious traffic violation, which not only disrupts road traffic order but also easily leads to traffic accidents. In minor cases, it can cause traffic congestion and reduce road capacity; in severe cases, it can lead to major traffic accidents, even resulting in fatal consequences with vehicles destroyed and lives lost.

Is it necessary to drain the water before adding windshield washer fluid?

It is not always necessary to drain the water before adding windshield washer fluid. If you previously used antifreeze windshield washer fluid, you can add more antifreeze fluid without draining the existing water. However, if you previously used non-antifreeze windshield washer fluid, it is advisable to drain the water before adding antifreeze fluid to prevent freezing. Functions of windshield washer fluid: Cleaning performance: Windshield washer fluid typically has wetting, penetrating, and solubilizing properties, which help clean and remove dirt. Antifreeze performance: The presence of alcohol and ethylene glycol significantly lowers the freezing point of the liquid, providing antifreeze protection and quickly dissolving frost.

What does 91V on car tires mean?

Tire marking 91V refers to the load index and speed rating. The number 91 represents the load index, indicating a maximum load capacity of 615Kg per tire, while the letter V signifies that the tire's maximum allowable speed is 240km/h. Specification markings: Tires are crucial components of vehicles, and they come in various specifications and models suitable for different vehicle types. These specification markings are typically found on the tire sidewall as a series of alphanumeric characters, representing the tire's tread width, aspect ratio, type, rim size, load index, and speed rating. Speed ratings: Based on their maximum sustainable speeds, tires are classified into different speed ratings from A to Z, with grade A further divided into eight subcategories (A1-A8). Generally, the later the letter appears in the alphabet for the speed rating, the better the tire's performance.

What does Vehicle Dynamic Control System mean?

Vehicle Dynamic Control System is a system and method for controlling vehicle dynamics. Design Purpose: Designed to improve driving stability, but cannot prevent accidents caused by sharp turns or careless/dangerous driving maneuvers. When driving on slippery roads or making turns on slippery surfaces, please reduce speed and drive carefully. When the system is active, the "SLIP" indicator on the dashboard will flash. The Vehicle Dynamic Control System includes: Calculating tire forces to obtain target vehicle forces and moments; Calculating equal steering angles for left and right wheels based on each tire's longitudinal μ ratio, lateral force, and vertical load; And controlling vehicle dynamics according to the calculated steering angles.

What does a white car taillight indicate?

A white taillight on a car is generally the reverse light. When the white light is on, it usually indicates that the car is reversing, but it does not blink. White light indicates an automatic transmission vehicle: If a car's white light blinks once before moving, it signifies that the car has an automatic transmission. This is because, in automatic transmission vehicles, the gear sequence from the parking position to the drive position passes through the reverse position, causing the reverse light to blink once. Function of reverse lights: Reverse lights serve two purposes: one is to alert pedestrians and vehicles behind, and the other is to provide a certain range of illumination assistance in low-light conditions.
