Here are the reasons why it is not recommended to fill up the car with fuel: Fuel leakage leads to waste and safety hazards: Gasoline storage at gas stations is very strict, especially in hot summers. Gasoline is stored underground where the temperature is kept very low. If the car is filled with fuel, it is likely to overflow from the vent hole, which not only causes waste but also poses a fire hazard if the spilled gasoline comes into contact with an open flame. Damage to the carbon canister: The carbon canister is usually installed between the fuel tank and the engine. Since gasoline is a volatile liquid, the fuel tank often contains vapor at room temperature. The fuel evaporation emission control system is designed to introduce the vapor into combustion and prevent it from volatilizing into the atmosphere. The activated carbon canister storage device plays a crucial role in this process. If the fuel tank is filled too much, liquid gasoline instead of gasoline vapor enters the carbon canister, which can damage it. Vent hole blockage: If the engine fails to start after refueling or if the car jerks while driving, don’t suspect the quality of the fuel. It is likely caused by an overfilled fuel tank. Once the vent hole is blocked, negative pressure will form inside the fuel tank, leading to poor fuel supply or even a complete lack of fuel supply.

What is the normal tire pressure for a car driving at high speed?

When driving at high speed, the standard tire pressure for a car ranges from 2.3 bar to 2.5 bar, while the reinforced type has a tire pressure between 2.8 bar and 2.9 bar. The maximum tire pressure should not exceed 3.5 bar. Tire pressure is not constant; as the tire temperature rises during driving, the internal tire pressure increases. In low-temperature conditions, the tire pressure is lower, and it rises during driving. Tire pressure refers to the air pressure inside the tire. When the tire pressure is too high, the vehicle's rolling resistance is small, and fuel consumption is low, but in emergency situations, sudden braking may be ineffective or the braking distance may increase. When the tire pressure is too low, the vehicle's comfort is better, providing a quiet and smooth ride, but the rolling resistance is high, leading to increased fuel consumption, and the vehicle is prone to standing waves and sudden tire blowouts at high speeds.

How to Know the Fuel Consumption per 100 Kilometers of a Car?

Methods for calculating a car's fuel consumption per 100 kilometers: The fuel consumption per 100 kilometers equals the fuel consumption (liters) divided by the driving distance (kilometers) multiplied by 100. The fuel consumption per 100 kilometers indicated in the manual of domestic cars is generally the constant-speed fuel consumption. Constant-speed fuel consumption refers to the fuel economy indicator when the car is driving at a constant speed on a good road. Several key technologies related to fuel consumption include three main aspects: 1. Vehicle weight: The relationship between vehicle weight and fuel consumption is directly proportional. For every 10% reduction in vehicle weight, fuel consumption will decrease by several percentage points accordingly. 2. Car design: Car design, with lower aerodynamic drag, will significantly reduce fuel consumption. The relationship between these two is also directly proportional. 3. Road conditions: Driving conditions are an important factor affecting fuel consumption.

Can I Report to Insurance Directly Without Calling Police After a Rear-End Collision?

Yes, but it depends on the situation. For minor accidents with repair costs not exceeding 2,000 yuan, you can directly report to the insurance company. After the insurance company confirms the claim, you can proceed with the repairs. However, if the repair costs exceed 2,000 yuan or if there are injuries, you must call the police. More relevant information is as follows: 1. Accident Scene Handling: In the event of a traffic accident on the road, the driver must immediately stop the vehicle and protect the scene. If there are personal injuries, the driver must immediately assist the injured and quickly report to the traffic police on duty or the traffic management department of the public security authority. If the scene is altered due to rescuing the injured, the original positions should be marked. Passengers, other drivers, and pedestrians should assist. 2. Accident Outcome Handling: For traffic accidents on the road that do not result in personal injuries and where the parties involved have no disputes over the facts and causes, they can immediately leave the scene, restore traffic, and negotiate compensation matters on their own. If they do not leave the scene immediately, they should quickly report to the traffic police on duty or the traffic management department of the public security authority.

What is the method for charging a car battery?

The methods for charging a car battery are: 1. Use a dedicated battery charger; 2. Use jumper cables for charging. The functions of the battery are: 1. When starting the engine, the battery supplies power to the starting system, ignition system, and electronic fuel injection system; 2. When the engine is stopped or idling at low speed, it powers the car's electrical equipment; 3. When the generator's output is insufficient, it can assist in powering the electrical equipment; 4. It mitigates voltage surges in the electrical system and protects the car's electronic devices; 5. It can store excess electricity generated by the alternator. The maintenance methods for the battery are: 1. Start the car regularly to charge the battery; 2. When the electrolyte is low, replenish it with distilled water or a dedicated replenishing fluid; 3. Regularly check if the small holes on the battery cover are ventilated during daily driving; 4. Check for signs of oxidation on the positive and negative terminals; 5. Inspect all parts of the circuit for signs of aging or short circuits; 6. Turn off all electrical equipment when leaving the car.

What kind of engine oil is suitable for BJ40?

BJ40 is equipped with a turbocharged engine, and it is recommended to use fully synthetic engine oil with a viscosity of 40. Turbocharged engines have higher requirements for engine oil. More details are as follows: 1. Engine oil is known as the lifeblood of the engine. Inside the engine, it not only lubricates but also cleans, seals, cushions, dissipates heat, and prevents rust. Without engine oil, the engine cannot operate normally. During operation, the engine oil forms a thin film on the surfaces of various components, preventing direct contact and friction. 2. When selecting engine oil viscosity, it is essential to choose the appropriate viscosity based on your engine's technical characteristics. The viscosity of the engine oil should neither be too high nor too low. If the viscosity is too low, the oil cannot form a stable film inside the engine. If the viscosity is too high, it increases the resistance during engine operation, affecting power output and fuel economy. Generally, a viscosity of 40 is suitable for turbocharged engines. 3. Over time, the performance of engine oil deteriorates, so it needs to be replaced regularly. It is advisable to change the engine oil on schedule during regular use and replace the oil filter each time. When purchasing an oil filter, always choose genuine products from reputable brands.

Where is the tire pressure reset button on the Toyota RAV4?

The Toyota RAV4 uses a direct tire pressure monitoring system and does not have a tire pressure reset button. The issue will automatically resolve after being addressed. When the tire pressure monitoring system alerts, promptly check and adjust the tire pressure. Only continue driving after confirming the tire pressure is normal. The tire pressure monitoring system will automatically reset after the vehicle has been driven for a certain distance. Direct Tire Pressure Monitoring: This system uses pressure sensors installed in each tire to directly measure tire pressure. The pressure information is transmitted wirelessly from inside the tire to a central receiver module, which then displays the tire pressure data for each tire. The system will automatically alert when tire pressure is too low or if there is a leak. Common Tire Pressure Reset Methods: First, turn on the ignition switch. Then, press and hold the tire pressure monitoring reset button until you hear a "beep" sound before releasing it. The tire pressure monitoring system will store the current normal tire pressure data, automatically clear the previous data, and finally, the dashboard warning light will turn off, indicating the tire pressure reset is complete.
