Are Car Air Purifiers Useful?

Car air purifiers are useful as they can purify the air inside the vehicle, filtering out bacteria, dust, and other particles. They can also filter and absorb harmful gases like formaldehyde in new cars. Below is relevant information about car air purifiers: 1. Causes of odors in the car: Excessive formaldehyde in the car's air mostly comes from decorative materials such as seat cushions, roof linings, and other upholstery, while benzene originates from adhesives. The smell of a new car is extremely harmful because the confined space makes it difficult for harmful gases to dissipate. Additionally, the human body emits harmful gases like carbon dioxide. Prolonged exposure to such a polluted environment while driving can easily cause discomfort and even lead to traffic accidents. 2. Function of car air purifiers: These devices use a small fan to circulate the air inside the car. Polluted air passes through a PM2.5 filter and an activated carbon filter inside the purifier, which filters or absorbs various pollutants. The air is then continuously ionized by a negative ion generator installed at the air outlet, producing a large number of negative ions. These ions are blown out by the fan, forming a negative ion airflow that ultimately cleans and purifies the air. 3. Types of car air purifiers: There are two main types. Filter-based purifiers: Maintenance for these products depends on the type of filter. Some filters require regular cleaning to maintain effectiveness, while others do not, though most need periodic replacement. Ion-based purifiers: Maintenance for these generally only requires replacing the ion generator, which can be done annually or even less frequently, with the longest interval being every six years.

Is it no longer necessary to display the insurance decal on new cars?

2020 vehicle insurance decals do not need to be displayed, vehicles only need to display the annual inspection decal. Although the annual inspection decal is connected to the traffic police system, failing to display the annual inspection decal is not allowed. Moreover, the new policy stipulates the merger of vehicle annual inspections and environmental protection testing. Additional information: 1. The latest regulations indicate that the environmental protection inspection and annual vehicle inspection decals have been combined into one, meaning this single decal can represent both the vehicle's annual inspection compliance and its environmental protection inspection compliance. 2. Vehicles only need to pass the annual inspection and no longer need to obtain a separate environmental protection decal. 3. In the past, vehicles were required to display annual inspection decals, environmental protection decals, and insurance decals. But now, the annual inspection decal and environmental protection decal have been combined into one, requiring only a single annual inspection decal to be displayed. 4. The 2020 vehicle decal regulations state that if an electronic insurance policy is used, there is no need to display an insurance decal.

What Causes a Car Radiator to Overheat?

Car radiator overheating can be caused by insufficient coolant, radiator leaks, etc. The specific reasons are as follows: Insufficient Coolant: Prolonged water circulation during engine operation can lead to coolant loss in the engine cooling system, resulting in a lack of water in the radiator; Radiator Leak: Broken or loose radiator connecting hoses can cause leaks, which will obstruct water circulation and lead to engine "boiling"; Cooling Fan Failure: A damaged cooling fan or a short circuit in the wiring can cause the fan to malfunction or rotate slowly, preventing the engine's heat from dissipating and naturally raising the engine's water temperature; Thermostat Failure: The thermostat is a device that controls the flow path of the coolant. If it becomes stuck or fails, the engine's large and small circulation will inevitably be affected, making it impossible to effectively dissipate heat.

What to Pay Attention to When Learning to Drive in Winter?

Here are the precautions for learning to drive in winter: 1. Keep Warm: In winter, don't prioritize style over comfort, especially keeping your hands and feet warm at all times for flexible operation. Carry a thermos with you to have hot water to drink and warm your hands. 2. Maintain Flexibility: Even if you're afraid of the cold, avoid wearing thick gloves while driving, and don't wear overly thick shoes. Sports shoes with good insulation are the most suitable. Do some warm-up exercises before getting in the car to loosen up your hands and feet. 3. Be Mindful of Road Conditions: Winter often brings rain, snow, fog, and frost. When learning to drive, pay attention to anti-skid and anti-fog measures, slow down as much as possible, keep the steering wheel steady, and learn to use the car's heater and windshield wipers. If staying in the car for a long time, crack open a window slightly to let in fresh air, which helps disperse fog and keeps your mind clear.

Can Water Enter the Transmission After a Car Drives Through Water?

It depends on the specific situation of driving through water. After driving through water, the transmission, differential, front and rear axles, and differential may all be exposed to water. Generally, water entering the transmission is mainly caused by the following two situations: Water level exceeds two-thirds of the wheel: If the water level exceeds two-thirds of the wheel, the probability of water entering the transmission is around 80% to 90%. If the water has already reached the level of the dashboard, the transmission is 100% certain to have water inside. Water splashes into the transmission during oncoming traffic: When encountering oncoming traffic, if there is excessive water on the road, it may cause water to enter the transmission. Once water enters the transmission, the performance of the transmission fluid will be affected. The performance of the transmission fluid will also degrade, leading to clutch slippage.
