What are the common faults of wipers?

1 Answers

Common faults of wipers are introduced in detail as follows: 1. Streaks: The optimal support point of the wiper arm is not found, causing the wiper blade not to fully contact the glass at every part. 2. Water droplets: After the wiper sweeps the windshield, small water droplets still adhere to the glass surface. 3. Wiper lifting phenomenon: When the car is driving at high speed, the wiper is lifted by the wind force, resulting in some areas not being swept. 4. Blade hardening: Due to direct sunlight and high temperature, the wiper blade hardens and loses elasticity. 5. Corrosion or blade wear: Poor climate, improper use of cleaning products, or substandard blade formula cause the edge of the wiper blade to be damaged or completely worn. 6. Foggy streaks: Caused by dirt, grime, or car wax adhering to the glass; contamination of the wiper blade by car wax or oil can also cause this phenomenon. 7. "Click" sound or harsh noise: Irregular wiper sweeping is mostly caused by blade wear, damage to the arm and bracket, or aging and deformation of the blade. 8. Blade cracking: The blade has a certain lifespan, and after exposure to cold, heat, acid, and alkali, it hardens, cracks, or peels. 9. Upper structure damage: Damage caused by ice scrapers or external force, resulting in structural damage to the wiper arm. 10. Blade contamination: Mostly caused by long-term accumulation of oil stains or car wax on the wiper, creating gaps between the wiper and the windshield, preventing complete water removal.

Are the Fuel Filter and Gasoline Filter the Same Thing?

Fuel filter and gasoline filter are the same thing. The main function of the fuel filter is to remove impurities from gasoline. If the fuel filter is dirty or clogged, the main symptoms include: slow or no response when accelerating, difficulty starting the car, and sometimes requiring 2-5 attempts to start the engine. Below are the symptoms of a clogged fuel filter: 1. Poor fuel supply: Poor fuel supply can cause gasoline atomization issues, leading to an imbalance in the air-fuel mixture ratio, incomplete combustion, and easily causing jerking. If this happens while driving, the jerking may not be noticeable or may be mild on flat roads but becomes more obvious when going uphill. 2. Idle engine vibration: If the fuel filter is clogged, the engine's fuel line will be obstructed, and the fuel injector's atomization will be poor, resulting in noticeable engine vibration at idle. However, idle vibration is not necessarily caused by the fuel filter; a clogged throttle can also cause idle vibration, so a comprehensive diagnosis is needed.

What is the shell under the car trunk called?

The plastic shell under the car trunk is called the rear bumper. The rear bumper is a device that provides a buffer when the car or driver is subjected to impact forces. The rear bumper consists of three parts: the outer panel, the buffer material, and the crossbeam. It has the ability to reduce injuries to passengers during high-speed collisions. Here is some relevant information: 1. Car bumper: The outer panel and buffer material of the car bumper are made of plastic, and the crossbeam is formed by stamping cold-rolled sheet metal into a U-shaped channel. The outer panel and buffer material are attached to the crossbeam. The car bumper is located in most areas at the front and rear of the car. On the surface, it is designed to prevent damage to the vehicle's safety system caused by external impacts and has the ability to reduce injuries to passengers during high-speed collisions. Nowadays, it is increasingly designed for pedestrian protection. 2. Specific functions: Plastic bumpers have strength, rigidity, and decorative properties. From a safety perspective, they can act as a buffer during collisions, protecting the front and rear body of the car. From an aesthetic perspective, they can naturally integrate with the car body, forming a seamless whole and serving as an important decorative component of the car's exterior.

What is the fuel tank capacity of the Toyota Yaris X?

Toyota Yaris X has a fuel tank capacity of 42 liters, which is the official data released. Owners who have purchased the Toyota Yaris X can also check this information on the vehicle's configuration sheet. The Toyota Yaris X requires 92-octane gasoline, with a fuel consumption of 5L per 100 kilometers. A full tank of fuel allows for a driving range of approximately 840km. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is typically observed through the fuel gauge inside the vehicle. Under normal circumstances, the fuel level will be accurately reflected on the gauge. The fuel gauge usually has 5 to 6 segments, and it is advisable to refuel when there are only 2 segments left to avoid running out of fuel midway. In actual refueling situations, the amount of fuel added may exceed the marked capacity. This is because the fuel tank capacity specified by the manufacturer is measured from the bottom of the tank to the safe fill level, and there is additional space from the safe fill level to the tank opening. This extra space is designed to accommodate fuel expansion due to temperature increases, preventing overflow. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the marked tank capacity.

How many kilometers can a Haval Big Dog run on a full tank of gas?

Haval Big Dog can run 318 kilometers on a full tank of gas. Solutions for high fuel consumption: 1. Clean engine carbon deposits: Excessive engine carbon buildup is a major cause, primarily due to the use of unsuitable fuel. It is recommended to add a certain amount of fuel cleaner when refueling. If the effect is not obvious, it indicates significant carbon deposits in the engine. In this case, the car must be taken to a 4S store for professional cleaning of the engine carbon deposits by technicians. 2. Check the oxygen sensor: As an internal control unit of the car, the oxygen sensor mainly monitors the fuel-air ratio in the engine. Once it is damaged, it will cause an imbalance in the fuel-air ratio, leading to a sudden increase in fuel consumption. After the oxygen sensor is damaged, the exhaust pipe will emit darker-colored exhaust gases while driving. At this point, the oxygen sensor should be replaced.
