What to Do If the Fuel Tank Under the Chassis is Scratched and Leaking?

If you find the fuel tank leaking, you can clean the leaking area and apply soap or chewing gum to temporarily seal the leak. When the fuel pipe is cracked, clean the cracked area, apply soap, wrap it with cloth or tape, and then apply another layer of soap. If the fuel pipe is broken, find a rubber or plastic tube with a similar diameter to the fuel pipe for connection. Secure both ends with wire. If the engine fuel pipe joint is leaking, wrap cotton yarn around the lower edge of the "horn" and tighten the fuel pipe nut and joint. Soften the soap with water, knead it into a putty-like consistency, and press it into the leaking area of the radiator. Filling the cooling fins can temporarily stop the leak.

What car does Nan Sun drive?

Nan Sun drives a BMW i3 pure electric vehicle. Advantages of the BMW i3 pure electric vehicle: The exterior has a high-tech feel, with the i3 featuring a suicide door design paired with retro-style suicide doors, making it much easier for rear-seat passengers to exit. Carbon fiber body – the BMW i3 is constructed entirely with a carbon fiber body. BMW has carbon fiber factories worldwide, requiring approximately 10 layers of carbon fiber to manufacture components used in the i3. Handling – the i3 continues BMW's tradition of excellent handling. Since the pure electric vehicle's battery is placed in the middle of the chassis, the overall weight distribution is relatively balanced compared to gasoline-powered cars, resulting in a solid chassis performance with strong controllability. Disadvantages: Comfort and interior configuration – the sense of cheapness is quite strong. The materials used for the front and rear door panels are very hard. The pure electric version comes standard with fabric seats, which are not as soft as those in BMW's sedan series. It still uses manual seat adjustment, and the cabin space, particularly the small rear windows, can feel somewhat oppressive. As a hatchback, the trunk space is also quite limited.

What Causes the Strong Jerking Sensation When Shifting from Second to Third Gear in an Automatic Transmission?

Introduction to the causes of a strong jerking sensation when shifting from second to third gear in an automatic transmission: Transmission issues: The jerking sensation during gear shifts in an automatic transmission can be caused by dirty transmission fluid, oil pump pressure leaks, or internal clutch slippage. A detailed analysis of the transmission's data stream is required to pinpoint the exact cause. Shift solenoid issues: If the vehicle has been in use for 2 years or has reached 60,000 kilometers, it may be necessary to replace the transmission fluid. If the problem persists after fluid replacement, the shift solenoids for second and third gears should be inspected. Engine oil passage blockage: The combustion of fuel, which is the source of the engine's power, is determined by the engine's ignition, air intake, and fuel injectors. If the air intake decreases, ignition weakens, or the fuel injection is reduced, the engine's power output will drop, leading to a jerking sensation.

Can You Drive with Low Tire Pressure in a New Car?

When the tire pressure is low, check the normal range for your vehicle's tires. If the tire pressure is within the normal range, you can drive; if it's below the normal range, you should not drive. Therefore, if the tire pressure is too low, it's best not to drive as it can cause significant harm to the vehicle. Low tire pressure in a new car may occur due to the following reasons: The car has been parked for too long, causing the tire pressure to decrease. When the car leaves the factory, the tire pressure is usually closer to the upper limit of the safe range. However, as the car remains parked for an extended period, the tire pressure gradually decreases. Some manufacturers intentionally lower the tire pressure to prevent excessively high speeds. Since it's a new car, even experienced drivers need an adaptation period. During this time, lowering the tire pressure slightly helps prevent traffic hazards caused by high speeds. Tire damage. Although rare in new cars, it's not impossible. The tire might have had issues at the factory or could have been punctured during use. If the low tire pressure warning appears in a new car, always check carefully for possible tire damage. Reasons for abnormal tire pressure: Generally, the system will alert if the pressure is below 1.8 bar or above 3.0 bar. In such cases, inspect the tires and adjust the pressure accordingly. The tire pressure monitoring system hasn't been reset. After inflating the tires, if the system isn't reset promptly, it will continue to display the old data, causing the tire pressure warning light to stay on. Simply reset the tire pressure monitoring system to resolve this. Damaged tire pressure sensor. The tire pressure sensor, installed inside the tire and connected to the inflation valve, monitors the tire pressure. If the sensor is damaged during driving (e.g., by hitting a curb), the tire pressure warning light may illuminate. In such cases, the only solution is to replace the sensor with a new one.

Is it necessary to install ETC?

You can apply for and install an ETC device. According to the regulations of the State Council, vehicles without ETC installed by 2020 will not enjoy toll discounts. In the future, only one manual lane will be retained at highway toll stations, and tolls can only be paid through manual channels. Additionally, newly installed ETC devices cannot be used on highways immediately; they must be activated first. During free holiday periods, ETC users can still use highways, and passing through ETC lanes will not incur charges. ETC Deduction Principles: There will be one or more ETC lanes on highways. Through dedicated short-range microwave communication between the on-board electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station, and by utilizing computer networking technology for backend settlement with banks, the system achieves the goal of vehicles paying tolls without stopping at highway toll stations. All of this operates on the principle of 'pass first, deduct later.' Benefits of Installing ETC: Time-saving: Eliminates the hassle of waiting in queues; Green and eco-friendly: Promotes low-carbon travel by reducing noise and exhaust emissions as vehicles pass through toll stations without stopping; Reduced wear and tear: Saves costs by decreasing the frequency of vehicle starts and brakes, thereby reducing wear and fuel consumption; Improved efficiency: ETC lanes can theoretically increase vehicle throughput by 2-3 times, making traditional ETC systems more updated, faster, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council explicitly stated in the '13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System' that 'by 2020, intercity transportation smart cards will be basically interoperable in key city clusters, and the proportion of vehicles equipped with ETC will significantly increase.' It also set a clear target in the '13th Five-Year Plan' for comprehensive transportation development: 'By 2020, the ETC usage rate for road passenger vehicles should reach 50%.' More future possibilities: In addition to continuously improving the convenience of ETC installation and usage and increasing the ETC adoption rate among passenger vehicles, efforts will be made to promote ETC usage among trucks in the future. There will also be exploration into deeper integration between ETC systems and smart transportation developments such as vehicle-to-vehicle communication and vehicle-road coordination, providing comprehensive travel services for vehicle owners. This means more application scenarios will support ETC usage.

How to Measure the Condition of Spark Plugs?

Spark plugs may indicate the following symptoms when they are faulty: Difficulty in starting the car, whether cold or hot, often requiring multiple attempts. Engine shaking, noticeable during driving. Reduced power, with a significant drop in performance compared to normal conditions. Increased fuel consumption. Stalling. Failed emissions tests. Common causes and diagnostics of spark plug failures: Several conditions can lead to non-functional spark plugs: Incorrect spark plug gap adjustment. A gap that is too small limits the contact area between the spark and the air-fuel mixture and suppresses flame kernel growth due to the quenching effect of the electrodes, resulting in weak sparks and ignition difficulties. A gap that is too large may exceed the ignition system's voltage capacity, preventing sparking. Cracked spark plug skirt. High-voltage current leaks through the crack, preventing sparking at the electrodes. Electrode carbon buildup, causing leakage from the center electrode to the surroundings instead of sparking to the side electrode. Excessive carbon deposits can short-circuit the spark plug, preventing sparks and damaging the insulator. Damaged electrodes. Prolonged electrical erosion or chemical corrosion from combustion gases can cause electrode breakage, rendering the spark plug non-functional. Low insulation resistance of the spark plug. This reduces the ignition voltage across the spark gap, weakening or completely eliminating the spark. Short circuit in high-voltage wires. Leakage in the wire from the ignition coil to the distributor can prevent the entire engine from starting, while leakage in the wire from the distributor to a spark plug can disable that cylinder's spark plug. Eroded platinum contacts. This can prevent all spark plugs from firing, making the engine unable to start or run normally. Faulty spark plugs should be replaced promptly. Replacement steps are as follows: Open the hood, remove the engine's plastic cover, and disconnect the high-voltage wires, marking each cylinder's position to avoid confusion. Use a spark plug socket to remove each spark plug, checking for and cleaning any debris like leaves or dust. Insert the new spark plug into the hole, hand-tighten it first, then use the socket to secure it. Reinstall the high-voltage wires in the correct firing order and replace the cover. Spark plug replacement interval: Typically replaced every 40,000-60,000 km under normal maintenance conditions, but this may vary by brand and engine type. Always refer to the owner's manual for specific recommendations.
