Why does the fuel cap warning light stay on after closing it?

What are the effects of adding 0.5 liters more engine oil?

Adding too much engine oil will increase the resistance of engine operation, affect the fuel consumption of the vehicle, increase engine noise, and raise the oil pressure in the crankcase. In severe cases, it may lead to oil burning. The specific functions of engine oil are as follows: 1. Reducing friction and high temperature: A sufficiently thick oil film separates the surfaces of relatively sliding parts, thereby reducing wear. 2. Sealing effect: Engine oil can form a seal between the piston ring and the piston, reducing gas leakage and preventing external pollutants from entering. 3. Anti-rust effect: Lubricating oil can adhere to the surface of parts, preventing contact with water, air, acidic substances, and harmful gases. 4. Buffering effect: When the pressure at the engine cylinder port rises sharply, suddenly increasing the load on the piston, piston pin, connecting rod, and crankshaft bearings, this load is transmitted and lubricated through the bearings, cushioning the impact load. 5. Cleaning effect: Good engine oil can carry carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank through circulation, and by the flow of the lubricating oil, it washes away dirt generated on the working surfaces of the parts.

How many centimeters can a nail penetrate a tire?

Different parts of the tire have varying thicknesses. The tread (crown) is approximately 16mm thick, with off-road tires being even thicker. The sidewall is about 6mm thick, while the bead area (toe) is around 12mm. From this, it can be understood that the tread is the thickest part of the tire, whereas the sidewall is the most vulnerable. Here is some relevant information about tires: 1. Check the tire's expiration date: The sidewall of the tire will have a four-digit number indicating the manufacturing date, with the first two digits representing the week and the last two the year. Generally, tires should not be used for more than 3 years or exceed 60,000 kilometers in mileage. 2. Pay attention to the sidewall: As the tire rubber gradually ages, deep grooves may appear on the sidewall. However, as long as the sidewall hasn't been impacted and the cords remain intact, the tire can still be used. The triangular marker on the sidewall helps the driver locate a protrusion in the tread grooves, which indicates the actual wear limit of the tire. That value should be greater than 1.6mm.

Do I Need to Press the Electronic Parking Brake After Parking?

Parking requires pressing the electronic parking brake, typically by first stepping on the foot brake and then pressing the electronic parking brake. For brief stops, such as waiting at a traffic light, it is not necessary to press the electronic parking brake. The electronic parking system replaces traditional parking brake levers, mechanical linkages, and cables with electronic buttons and motor components, but its working principle remains the same as that of a mechanical handbrake. Here is an introduction to the electronic parking brake: 1. Definition: The electronic parking brake, also known as the Electronic Parking Brake (EPB), is a technology that achieves parking braking through electronic control. Its working principle is the same as that of a mechanical handbrake. 2. Working Principle: When parking, after the driver presses the electronic button of the Electronic Parking Brake system, the electronic control unit will control the motors integrated in the left and right brake calipers to act, driving the brake caliper pistons to move and generate mechanical clamping force, thereby completing the parking process.

Is the BMW X1 better with front-wheel drive or rear-wheel drive?

BMW X1 adopts front-wheel drive configuration, here are the relevant details: 1. Front-wheel drive concentrates the transmission system near the cabin, combining the noise from power transmission with suspension system vibrations, which creates environmental pollution and physical discomfort for drivers, thus requiring higher interior material costs. 2. In terms of power performance, front-wheel drive can achieve greater driving force. This is because the main function of the final drive is to reduce speed and increase torque. Rear-wheel drive vehicles typically position the final drive farther from the gearbox and engine, allowing for a larger driven gear distribution circle in the final drive to achieve higher gear ratios.

How long can a vehicle's compulsory traffic insurance be expired without penalty?

Compulsory traffic insurance can be expired for up to three months without penalty, but exceeding this period will result in fines. Below is relevant information about compulsory insurance: 1. Definition: The full name of compulsory traffic insurance is "Compulsory Motor Vehicle Traffic Accident Liability Insurance." It is a mandatory liability insurance where the insurance company compensates for personal injuries, fatalities, and property losses (excluding the vehicle's occupants and the insured) caused by the insured motor vehicle in a road traffic accident, within the liability limits. 2. Compulsory insurance must be purchased: According to the "Regulations on Compulsory Motor Vehicle Traffic Accident Liability Insurance," starting from August 2008, all new vehicles and vehicles with expired insurance must purchase compulsory traffic insurance upon renewal. Taking six-seat vehicles as an example: private car premiums are 950 yuan, non-operational corporate vehicles are 1,000 yuan, non-operational government vehicles are 950 yuan, and operational rental vehicles are 1,800 yuan. Insurance companies will determine the premium based on the vehicle's sales invoice.
