Why does the Geely Englon suddenly fail to start?

Why is the high-pressure pipe of the car air conditioner icy cold?

The reasons why the car air conditioner pipes become icy cold or even freeze include: clogged air conditioner drain holes, high moisture content in the refrigerant within the air conditioning system, faulty evaporator temperature sensor, or a blocked expansion valve. Frozen air conditioner pipes can affect the cooling performance of the car air conditioner, so it is advisable to promptly inspect and repair at a maintenance shop. More details are as follows: 1. Cause: After passing through the expansion valve, the refrigerant becomes very cold, and then the icy refrigerant flows to the evaporator. In front of the evaporator, there is a blower specifically designed to draw in fresh air from outside the car and blow it over the cold evaporator. The temperature of the ambient air drops sharply after passing through the evaporator, turning into the cold air that is blown out. 2. Result: If the high-pressure pipe of the air conditioner is icy cold or even frozen, it is likely due to the compressor not working properly or pressure leakage along the way, preventing the refrigerant from achieving sufficient pressure to lower the temperature. This disrupts the entire air conditioning refrigeration cycle, rendering the air conditioner unusable.

What Are the Gears in an Automatic Transmission Car?

Automatic transmission cars have the following gears: 1. P (Park) - This is the parking gear. If the car is stopped and the engine is turned off, it must be shifted into P gear. 2. R (Reverse) - This is the reverse gear, used for backing up, parallel parking, or reversing into a garage. 3. N (Neutral) - This is the neutral gear, used when waiting at a traffic light for an extended period. However, the brake must be pressed because the car can roll on a slope if left in neutral. 4. D (Drive) - This is the driving gear. To move the car, it must first be shifted into D gear. 5. S (Sport) - Also known as the hill-climbing gear, S gear is used when driving on steep slopes. An automatic transmission eliminates the need for the driver to manually shift gears, as the vehicle automatically selects the appropriate gear based on driving speed and traffic conditions.

Does Car Window Glass Block UV Rays?

It depends on the material of the car glass. If it is organic glass, resin glass, or plastic glass, it can effectively block ultraviolet rays. Ordinary glass can block over 90% of UV rays with wavelengths less than 300nm, but it cannot block 90% of UV rays with wavelengths greater than 350nm. Quartz glass and silicon dioxide glass, however, cannot block UV rays. Here is some additional information: 1. About UV rays: UV rays are a dangerous sunlight hazard. With their relatively long wavelengths and strong penetrating ability, they can penetrate the skin's surface, reach tissues below the dermis, and damage the skin's fine structures, such as collagen and elastic fiber tissues, causing wrinkles and fine lines, and leading to skin relaxation and aging. This is medically referred to as photoaging. 2. Harm to the human body: In the energy distribution of UV rays in sunlight, UVA is 15 times that of UVB and is the main cause of skin tanning. It can reduce the content of hyaluronic acid, which binds water in the skin, leading to dry skin, accelerating melanin formation, darkening the skin tone, and is also an important cause of skin cancer.

How to Clean a Three-Way Catalytic Converter?

A three-way catalytic converter can be cleaned as follows: 1. Start the engine and wait until the coolant temperature reaches normal operating levels before shutting it off; 2. Pour the cleaning product into a specialized device and connect the device's output connector to the vacuum hose; 3. Restart the engine, maintain the RPM at around 2000, open the flow control valve, and slowly drip the product into the intake manifold over a period of approximately 30 minutes; 4. After cleaning, keep the engine running at the same RPM for 3-5 minutes to expel any residual liquid. Below is an introduction to the three-way catalytic converter: The three-way catalytic converter is an emission control device in the engine. Its proper functioning determines the engine's fuel consumption, power output, and emission levels. If it becomes clogged or malfunctions, exhaust emissions will exceed standards. Additionally, it can affect engine performance, commonly manifested as increased fuel consumption, sluggish acceleration, unusual exhaust noises, and foul-smelling emissions.

What does 'back' mean in the context of automobiles?

In the context of automobiles, 'back' refers to the action of making a U-turn. Here is an introduction to vehicle U-turns: 1. A vehicle U-turn (motor vehicle turning back) is an operation that changes the direction of the vehicle by 180° under road conditions where U-turns are permitted. Sometimes, U-turns are also required in non-road conditions such as parking lots, using essentially the same method. 2. Vehicle U-turns must strictly comply with the regulations of road traffic management: 'Motor vehicles are not allowed to make U-turns at railway crossings, pedestrian crossings, curves, narrow roads, bridges, steep slopes, ramps, or any sections where danger is likely to occur.' 3. Therefore, it is essential to choose safe locations with minimal traffic, such as intersections with low traffic volume, flat and wide areas with solid shoulders. Depending on the road width and traffic conditions, vehicle U-turns can be categorized into single-motion U-turns or U-turns that combine forward and reverse movements.
