What is the issue with squeaking noise during semi-engaged clutch start in first gear?

Why is the high-pressure pipe of the car air conditioning cold while the low-pressure pipe is not cold?

When the high-pressure pipe of the car air conditioning is cold while the low-pressure pipe is not, it indicates that the compressor is damaged. Under normal working conditions, the low-pressure pipe should be cold, and the high-pressure pipe should be hot to the touch. If the high-pressure pipe is cold, it means the compressor is faulty and needs to be replaced. The air conditioning working process: Compression process: The compressor sucks in the low-temperature, low-pressure refrigerant gas from the evaporator outlet and compresses it into high-temperature, high-pressure gas, which is then discharged from the compressor. Heat dissipation process: The high-temperature, high-pressure superheated refrigerant gas enters the condenser. Due to the decrease in pressure and temperature, the refrigerant gas condenses into a liquid, releasing a large amount of heat. Throttling process: The higher-temperature and higher-pressure refrigerant liquid passes through the expansion device, where its volume increases, and the pressure and temperature drop sharply, exiting the expansion device in a mist form (fine liquid droplets).

What is the average range of a car in kilometers?

Generally, the fuel range of civilian vehicles when fully refueled exceeds 500 kilometers. Typically, small cars have a fuel tank capacity of 35-45 liters, while medium-sized cars have a fuel tank capacity of around 55-75 liters. After a full refuel, most vehicles can travel approximately 500 kilometers. The size of the fuel tank correlates with the car's displacement and fuel consumption—larger fuel tanks for higher consumption and smaller tanks for lower consumption. Factors affecting the range include: Battery technology impacts range: The increase in electric vehicle range is the result of multiple factors. To enhance the range, the key lies in battery technology, which requires continuous improvement in battery performance. However, considerations must also be given to factors such as vehicle size and price. Other factors affecting range: High and low-temperature battery technology, optimization of battery BMS technology, upgrades to the vehicle's energy recovery system, lightweight body construction, and energy-saving technologies for hardware equipment. Additionally, external driving conditions, air resistance coefficient, mechanical transmission efficiency, overall vehicle weight, and passenger count are among the factors that influence the actual range of electric vehicles.

Can You Still Drive with a Tire Pressure of 200?

A tire pressure of 200 is too low to drive safely. It is best to adjust it to the normal tire pressure before driving. Normally, the tire pressure for a car should be between 2.2 and 2.5, which is considered safe as long as it falls within this range. The standard original tire pressure for passenger cars is between 2.3 and 2.5 bar, which is within the normal range. The maximum should not exceed 3.0, and the minimum should not be below 2.1. Hazards and impacts of abnormal tire pressure on driving: Impact on braking performance: The friction and adhesion of the tires will decrease, affecting braking performance. Reduced comfort: It can cause steering wheel vibration and deviation, reducing driving comfort. Decreased tire lifespan: It accelerates localized wear of the tread pattern in the center of the tire, shortening the tire's lifespan.

Why Does the Car Unlock Automatically?

The reason for the car unlocking automatically might be that one of the four doors was not properly closed when locking the car, or the trunk door was not properly closed. For most car models, if any door is not properly closed, it will prevent the car from being fully locked. Other reasons are as follows: Doors not fully locked: When locking the car, the doors are closed and locked but not fully secured. In this case, even if the lock button is pressed, the doors will not remain locked. Accidentally pressing the unlock button on the remote: After locking the car, other objects in the pocket within the remote's range might accidentally press the unlock button. Many people like to keep their car keys bundled with other keys, making this situation quite common.

What are the consequences if the car expansion tank cap fails to release pressure?

The failure of the radiator cap to release pressure will cause the radiator to malfunction, affecting the normal working performance of the engine. The radiator cap, also known as the pressure radiator cap, is installed on the car's radiator and is an important component of the car's cooling system. The radiator cap is equipped with a valve that generates pressure, helping to maintain the engine at an effective temperature. How the radiator works: When the car is running, the temperature of the radiator increases, and the pressure inside the radiator rises. When the pressure reaches a certain level, the pressure valve is pushed open, allowing the coolant to flow into the adjacent overflow tank. When the car stops running, the cooling system will draw the water back from the overflow tank. Precautions for radiator use: Never fill the car radiator with tap water, as prolonged use of tap water can cause rust or scale buildup in the radiator. This is a very common issue. Rust and scale can restrict the flow of antifreeze in the cooling system, reducing the radiator's heat dissipation performance and, in severe cases, damaging the engine.

Can Water Damage to Car Film Self-Recover?

Water damage to car film cannot self-recover. If the amount of water is relatively small, it may cause the film to become loose, and the film may peel off later. If there is too much water ingress, spreading to some circuits, it may cause a short circuit. Here are some precautions regarding car film application: Wash the car in advance: When applying film to the car, washing the car provides thorough preparation. Dirty car windows will affect the film application effect. Leave sufficient blank space for side mirrors: When applying film to the front two windows, special attention should be paid. The car owner should personally test it by sitting in the car - the film must not obstruct the driver's view of the mirrors. Pay attention to protection: After completing the film application, do not roll down the windows for 3 days, otherwise it will affect the film. Sometimes this may cause the film to become less secure.
