Reasons for loud noise when the car air conditioner is on: 1. The fan blades inside the air conditioner are deformed and need to be replaced; 2. The motor of the fan inside the air conditioner is faulty, it is recommended to repair or replace the fan; 3. There is excessive dirt inside the air conditioner, it is recommended to clean the air conditioner. The car air conditioning refrigeration system consists of a compressor, condenser, liquid storage dryer, expansion valve, evaporator, and blower, all connected by copper pipes and high-pressure rubber hoses to form a sealed system. When the refrigeration system is operating, the refrigerant circulates in different states within the sealed system. The car air conditioner is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the car cabin to a better state, providing a comfortable riding environment for passengers, reducing travel fatigue, creating good working conditions for the driver, and ensuring safe driving.

How to Solve the Steering Wheel Noise Issue in Envision?

Here are the solutions for the steering wheel noise issue in Envision: Friction between the steering column and floor mat: This is mainly caused by oversized aftermarket floor mats (such as full-coverage mats) that come into direct contact with the steering column. The movement of the steering column creates friction. The solution is to adjust the position of the floor mat or replace it. Faulty clock spring in the steering wheel: Particular attention should be paid if the steering wheel has been disassembled before. The issue could be a broken clock spring or an unplugged clock spring connector. Replace or secure it accordingly. Aging or loose steering tie rod end: Replace the steering tie rod end, but a wheel alignment is required after replacement.

How to Determine Whether a Car is China 5 or China 6 Standard?

Methods to determine whether a car is China 5 or China 6 standard: The China 5 or China 6 labels are not displayed on the vehicle itself but can be identified through the data on the vehicle acceptance certificate, where China 5 is represented as Ⅴ and China 6 as Ⅵ in Roman numerals. China 5 and China 6 refer to the national standards for vehicle exhaust emissions. The higher the number, the more environmentally friendly the vehicle's exhaust emissions are, with China 1 being the most polluting and China 6 the least. The China 6 emission standard is an upgraded version of the current China 5 standard, imposing stricter and more scientific requirements on vehicle exhaust pollutants. Compared to the existing China 5 standard, the China 6 standard features significant optimizations in multiple aspects, enabling a more comprehensive and objective assessment of vehicle emission levels while being easier to implement and regulate.

Where Should Motorcycles Stop at Traffic Lights?

In areas where motorcycle riding is permitted, dedicated motorcycle lanes are usually set up on the far right side of the road, adjacent to pedestrian lanes. Motorcycles are required to use these dedicated lanes as per regulations. Therefore, when waiting at traffic lights, motorcycles should stop within the marked boundaries of the motorcycle lane and must not encroach into car lanes. Below are relevant details: 1. Regulations: Article 38 of the Implementation Regulations of the Road Traffic Safety Law of the People's Republic of China states: Green light signals for motor vehicles and non-motor vehicles indicate that vehicles are permitted to proceed, but turning vehicles must not obstruct the passage of straight-moving vehicles or pedestrians. When the yellow light is on, vehicles that have already crossed the stop line may continue to proceed. When the red light is on, all vehicles are prohibited from proceeding. 2. Precautions: Wear a safety helmet, gradually reduce speed to stop, wear low-heeled shoes, and avoid wearing slippers or high heels.

What is the fuel consumption of a motorcycle?

There are many types of motorcycles, and the fuel consumption varies depending on the displacement and type of motorcycle. Taking the common 125cc cross-type motorcycle as an example, the fuel consumption per 100 kilometers is generally around 2.2 liters, while for a 125cc scooter, the fuel consumption per 100 kilometers is about 3 liters. Here are some related motorcycle precautions: 1. Pay attention to daily maintenance: For scooters, frequent oil changes and air filter replacements are crucial. It is recommended to change the oil every 1,500 kilometers (using high-quality oil) and replace the air filter every 2,000 kilometers. 2. Choose high-quality tires: Durable tires are a good choice, and since scooters have a lower chassis, tires are particularly important. 3. Mind your speed and riding style: Avoid frequent stops and accelerations while riding. Maintaining a relatively steady speed is essential. It is advisable to keep the speed between 40-60 km/h for optimal performance.

What Kind of Battery Can Have Water Added?

Here is the relevant information: 1. Maintenance-free batteries: Many batteries today are maintenance-free, meaning they do not require water addition. If such batteries experience a decline in range, it is usually due to battery aging. For these types of batteries, the only option is replacement; they cannot be repaired by adding water. 2. Effects of adding water: Next, let’s look at the effects after adding water. Generally, for electric vehicle batteries, adding water can restore about 60% of the battery’s performance if it hasn’t bulged from overcharging, but this state can only last for a few months or even weeks. It fundamentally cannot solve the problem of reduced battery range. Additionally, it’s important to note that if the amount of water added is not precise, it can directly damage the battery, leading to its complete failure. Furthermore, it’s worth mentioning that if the battery has already bulged from overcharging, adding water will have no effect at all. Therefore, for bulged batteries, adding water cannot repair them, and replacement is the only option.
