How to Repair a Cracked Plastic Fuel Tank?

Currently, the non-metal fuel tanks used in vehicles are made by molding a mixture of resin and ABS engineering plastic in specific proportions. Although this material can be repaired by high-temperature fusion for cracks, the strength after such repair is significantly lower than the original factory condition. Since fuel tanks involve safety issues, it is best to replace them. Below is more relevant information about fuel tanks: 1. The components of a fuel tank include: fuel tank cap, partition, fuel gauge sensor, fuel inlet and return pipes, fuel filler neck, and vent. 2. The maintenance methods for fuel tanks are: cleaning the air valve and vapor valve, and regularly removing sediment from the tank. 3. The function of a diesel engine is: to convert the thermal energy of gasoline or diesel into mechanical energy by burning the fuel in a sealed cylinder, causing the gas to expand and push the piston to perform work. 4. The maintenance methods for diesel engines include: (1) Using qualified engine oil. (2) Using qualified coolant. (3) Regularly cleaning scale from the radiator. (4) Periodically removing carbon deposits from the engine.

How long can the Civic continue to drive when it displays 'Change Engine Oil Now'?

The Civic displays 'Change Engine Oil Now' with approximately 800 kilometers remaining, as the factory vehicle's reminder is based solely on a fixed maintenance cycle. The functions of engine oil: Engine oil, also known as motor lubricant, serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and cushion shocks in the engine. It is often referred to as the 'blood' of the car. How to check engine oil: After adding engine oil, start the vehicle and then turn it off for 3 minutes before checking. This is because changing the oil also requires replacing the oil filter, which initially contains no oil. Starting the vehicle allows oil to flow into the filter. Waiting 3 minutes ensures the oil settles into the oil pan, providing a more accurate reading. Do not check the oil level on a slope, as the tilted position of the vehicle causes the oil in the pan to tilt as well, leading to an inaccurate measurement.

What is BYD's battery degradation standard for battery replacement?

BYD's battery degradation standard for battery replacement is as follows: 1. 1 to 10 years: The degradation rates are 8%, 4%, 2%, 2%, 2%, 1.5%, 1.5%, 1.5%, 1.5%, 1.5% respectively. 2. Over three years: The battery degradation level has already affected normal usage. 3. Grading: When the current battery capacity is lower than the nominal capacity, it is considered degraded. When the capacity falls below 20%, it is deemed severe battery degradation. There are many reasons for battery degradation, mainly including: 1. Quality issues: Poor battery quality itself. 2. Poor charger: Using inferior chargers. 3. Working environment: Operating in high or low-temperature environments for extended periods. 4. Overcharging and discharging: Using the battery until the remaining charge is below 3%. Circuits have protection, but it occasionally happens. 5. Radiation: Long-term use of the battery in areas with strong electromagnetic radiation (which can interfere with the conductivity of metals inside the battery).

Causes and Solutions for Car Air Conditioner Evaporator Freezing

The causes and solutions for car air conditioner evaporator freezing are as follows: Compressor malfunction due to prolonged use: Reduced compression efficiency or damage to the compressor's gas distribution system can lead to excessively low pressure, causing freezing. The freezing typically occurs in the front section of the evaporator. Adding some refrigerant can resolve the issue. If the problem persists, the compressor must be replaced. Excessive refrigerant: Some air conditioners may have refrigerant added due to relocation or leaks. Improper handling by maintenance personnel can result in too much refrigerant, causing excess refrigerant to flow to the rear section of the evaporator and freeze. This type of freezing usually occurs in the rear section of the evaporator and around the compressor's return pipe. Releasing the excess refrigerant will resolve the issue. Dirty evaporator: After prolonged use, dust from the air or microorganisms generated by the evaporator can accumulate on the evaporator, obstructing airflow, reducing heat exchange, and causing the evaporator temperature to drop too low, leading to freezing. The freezing occurs in the rear section of the evaporator. After the ice melts, rinse the evaporator with water and gently brush along the fins with a soft brush, being careful not to wet the electrical components. Cleaning thoroughly will resolve the issue.

What Causes the Steering Wheel to Be Misaligned When Driving Straight?

The reasons for the steering wheel being misaligned when driving straight are as follows: 1. Wear and looseness of the steering tie rod ball joint pin, or loosening of the fastening nut. 2. Severe wear of the steering knuckle kingpin and bushing, leading to increased clearance. 3. Excessive axial clearance of the front wheel bearings or wear. Solutions are as follows: 1. Adjust the toe-in. Collisions during driving can deform the steering rod and tie rod, wear out various ball joints, or cause irregular tire wear, leading to increased or decreased toe-in. 2. Wheel dynamic balance. After a certain mileage, the original wheel balance weights may be lost, or the wheel hub may be deformed, causing the front end to wobble and the steering wheel to shake at high speeds. 3. Check the tie rod. Looseness of the tie rod ball joint or bracket can cause instability during driving. 4. Check the wheel hub bearings. Loose wheel hub bearings or severe wear of the left and right steering knuckle ball joints can lead to inaccurate front wheel alignment. 5. Check the steering damper. A damaged or leaking steering damper, or deformed front suspension springs, can also affect the car's stability during driving.

Where are the vehicle clearance lights located?

Vehicle clearance lights are located at the outermost lights on the front and rear of the car. Their functions are: 1. According to GB7258 "Technical Conditions for Safe Operation of Motor Vehicles" Article 8.2.6, vehicles with an unladen height exceeding 3.0m or a width exceeding 2.10m must be equipped with clearance lights; GB4785 "Installation Requirements for External Lighting and Signaling Devices of Motor Vehicles and Trailers" Article 4.3.17 specifies the quantity, configuration, layout, light color, installation position, and circuit connection requirements for clearance lights. Without altering the existing connection method, adding a red light distribution surface to the rear of the front clearance light effectively incorporates the function of a rear clearance light. 2. Function of clearance lights: The term "clearance light" can be understood literally - "clearance" indicates warning, and "light" refers to outline. These are warning lights that serve as cautionary signals to alert other vehicles. 3. Installed along the top edges of the vehicle, they indicate both the height and width of the car. Safety regulations mandate that vehicles taller than three meters must be equipped with clearance lights. The color specification for clearance lights is white at the front and red at the rear.
