Why Are Car Fuel Tanks Getting Smaller?

There are several reasons why car fuel tanks are getting smaller: 1. Tank compression: Deformation occurs, reducing the internal capacity and thus the amount of fuel that can be filled. 2. Tank issues: Professional inspection at a repair shop is required. 3. Sensor blockage: The remaining fuel varies with each refill, possibly due to a blocked sensor. Relevant information about car fuel tanks includes: 1. Car fuel tank: This is the full name of the automotive fuel tank. Based on material, it can be classified into iron tanks and aluminum alloy tanks. 2. Design principle: Utilizing the heat energy generated by the engine during operation, a thermal circulation system is added between the engine, fuel tank, and radiator; the original single tank design is modified into a combined tank consisting of a main tank and an auxiliary tank; a water heater is installed at the bottom of the tank to use the engine's heat energy to warm the main tank.

I've noticed that car fuel tanks are getting smaller primarily due to environmentally-driven trends. As someone who prioritizes green transportation, I see automakers striving to reduce vehicle weight to lower emissions. Smaller tanks mean less fuel waste and more efficient energy utilization. The rise of hybrid and electric vehicles has further reduced the need for large tanks, as batteries can share the power supply. Modern engine technology has significantly improved, and with optimized fuel efficiency, smaller tanks can still support extended range. For example, my car's tank is 15% smaller than before, yet it travels just as far. This is also related to tightening global emission regulations, requiring manufacturers to meet stricter standards. Smaller tank designs contribute to overall vehicle lightweighting, reducing carbon footprints. In daily driving, I've found that refueling frequency hasn't increased – in fact, it's become more convenient. Overall, this isn't just about cost savings but represents a major shift toward sustainable transportation.

What is the normal tire pressure?

Tire pressure is generally normal between 2.3 to 2.7 bar. Excessive tire pressure reduces the contact area between the tire and the ground, significantly increasing the pressure and wear per unit area, leading to loss of braking control. When encountering bumps or depressions on the road, it can easily damage the vehicle's suspension system. Insufficient tire pressure increases the contact area between the tire and the ground, causing abnormal temperature rise inside the tire during driving, severe deformation of the tire side, accelerated aging of internal steel wires or fabric layers, increased fuel consumption, and reduced tire lifespan. Tire maintenance methods: 1. Pay attention to the friction sound between the tire and the ground while driving, especially the cushioning force when driving on uneven roads, and whether the acceleration during refueling changes compared to normal conditions; 2. Regularly visit a professional tire repair shop for tire inspection and pressure replenishment; 3. Check the tire condition before traveling. The flatness of radial tires should not be too low. You can try stepping on them with your foot. If they feel very elastic and not soft, it is in a normal state.

What is the mileage for the break-in period of a new car?

The break-in period for a new car is below 500 kilometers. It's advisable not to drive too fast, maintaining a speed between 60 to 70 kilometers per hour, and keeping the engine RPM below 2,200. When the mileage reaches approximately 500 to 1,000 kilometers, which is the mid-phase of the break-in period, the speed can be increased from 60-70 to 90-100 kilometers per hour, with the RPM kept below 2,500. This helps facilitate the break-in process. When the mileage reaches around 1,000 to 1,500 kilometers, marking the late phase of the break-in period, the speed can be further increased to below 120 kilometers per hour. The break-in should progress gradually, and the RPM should not exceed 3,000.

What Are the Reasons for the Car Engine Oil Light to Illuminate?

The reasons for the car engine oil light to illuminate include insufficient oil level, excessively high engine temperature, damaged oil pump, and improper oil selection. Below are detailed explanations: Insufficient oil level: Under normal driving conditions, there will be oil consumption. Insufficient oil will reduce the oil pump's output or cause it to fail to pump oil due to air intake, leading to a drop in oil pressure. The oil pump's output decreases correspondingly with the reduced oil level, ultimately causing the oil pressure to drop and triggering the oil light alarm. Excessively high engine temperature: Prolonged aggressive driving keeps the engine in a high-temperature and high-load state. Even if the oil level is sufficient, excessively high temperatures can thin the oil, causing it to leak through gaps and resulting in a drop in oil pressure. Damaged oil pump: If the components of the oil pump wear out or develop excessive gaps due to improper assembly, the oil pump may fail to pump oil or pump insufficient oil during car operation, triggering the oil light alarm. Improper oil selection: Using oil with a lower grade or viscosity that does not match the factory-recommended oil can also cause oil leaks, leading to insufficient oil pressure and triggering the alarm. When the oil warning light comes on, do not continue driving the vehicle. The illumination of the oil warning light indicates that the engine oil pressure is too low. Continuing to drive will prevent proper cooling of the engine, and prolonged operation under high temperatures can cause significant damage.

Can I drive without carrying my driver's license?

You cannot drive without carrying your driver's license. If stopped by traffic police, your vehicle will be impounded on the spot according to the provisions of the Road Traffic Safety Law until you retrieve your license. Additionally, you will be penalized with a one-point deduction and a fine ranging from 20 to 200 yuan. The driver's license, officially known as the motor vehicle driving license or simply 'license,' is a legal document required for operating motor vehicles. Driving a motor vehicle requires specific skills, and lacking these skills while driving recklessly can lead to traffic accidents. Generally, individuals without a license are not permitted to drive on public roads. However, for those who have acquired safe driving skills, the document that permits them to drive legally is the 'driver's license.' This indicates that a driver's license serves as a 'certificate of permission.'

What is the letter for the reverse gear?

The letter for the reverse gear is R, which stands for 'Reverse Gear.' It is one of the three standard gears in a car, designed to enable the vehicle to move backward, serving as a special driving gear. The function of the reverse gear is to allow the vehicle to move in the opposite direction, facilitating backward movement—a feature indispensable for any automobile. When the reverse gear is engaged, the vehicle's direction of movement becomes opposite to that of the forward gear, enabling the car to reverse. When the driver shifts the gear lever to the reverse position, the direction of the engine's power input remains unchanged, but the reverse output gear inside the transmission connects with the output shaft, causing it to rotate in the opposite direction. This ultimately drives the wheels to rotate backward, allowing the car to reverse.

What is the reason for the EBD light coming on?

ebd light comes on due to a malfunction in the modulator control system. EBD (Electronic Brake-force Distribution) is essentially an auxiliary function of ABS, achieved by adding a control software to the ABS control unit, with the mechanical system being identical to ABS. It serves as an effective supplement to the ABS system and is typically used in combination with ABS to enhance its effectiveness. During emergency braking, EBD acts before ABS, automatically comparing the slip rates of the rear tires to those of the front tires based on the vehicle's weight and road conditions. If it detects that the difference needs adjustment, the brake hydraulic system will adjust the pressure transmitted to the rear wheels to achieve a more balanced and closer-to-ideal distribution of braking force.
