Should You Use a Dry or Wet Towel to Wipe After Car Waxing?

After car waxing or polishing, use a dry towel to wipe. The relevant explanations are as follows: 1. Reason: After car waxing and polishing, it is essential to use a dry and clean towel for wiping. It is best to choose a professional microfiber plush towel, as the particles of microfiber plush towels are smaller, denser, and the surface is smoother and softer, which will not scratch the car paint. 2. Benefits of car waxing: Waxing is beneficial for car maintenance and care. The primary function of waxing is waterproofing and protection against acid rain. Due to the protection of car wax, the amount of water droplets adhering to the car body is significantly reduced, with an effect ranging from 50% to 90%. Secondly, it protects against high temperatures and UV rays. Cars driven or stored outdoors year-round are prone to paint aging and fading due to sunlight exposure.

What is the General Power Rating of Electric Vehicle Motors?

Electric vehicle motor power varies depending on the type of motor, and there is no uniform data. The working principle is that the power source provides electrical energy to the drive motor of the electric vehicle, which then converts this electrical energy into mechanical energy, either through a transmission device or directly driving the wheels and working mechanisms. Below are the requirements for electric vehicle motors: 1. Overload capacity: The drive motor of an electric vehicle needs to have 4-5 times the overload capacity to meet the demands of short-term acceleration or climbing. 2. Speed: The maximum speed of an electric vehicle is required to be 4-5 times the cruising speed on highways. 3. Reliability: The drive motor of an electric vehicle demands high operational controllability, steady-state accuracy, and good dynamic performance.

What are the reasons for insufficient cooling in a sedan's air conditioning system?

There are several reasons why a car's air conditioning system may not cool effectively: 1. Damaged expansion valve: A faulty expansion valve prevents the formation of high pressure in the system before the valve, resulting in the high-pressure refrigerant failing to reach 150Kpa. This causes the evaporator behind the expansion valve to not cool down, leading to ineffective air conditioning. 2. Internal wear of the air conditioning compressor: Wear inside the compressor causes the pressure between the compressor and the expansion valve to not reach 150Kpa~200Kpa, preventing the refrigerant in the system from circulating normally and resulting in poor cooling. 3. Idle speed too low: An excessively low idle speed may lead the vehicle's computer to determine that turning on the air conditioning could cause the engine to stall.

Is the Lincoln MKZ Fully Imported?

The Lincoln MKZ is a fully imported model, as this vehicle is not domestically produced. Below is more information about it: 1. The Lincoln MKZ is a mid-size luxury car under the Lincoln brand, available in both hybrid and pure gasoline versions. The pure gasoline version uses two types of engines: one is a low-power 2.0-liter turbocharged engine, and the other is a high-power 2.0-liter turbocharged engine. 2. The Lincoln MKZ has a length, width, and height of 4925 mm, 1864 mm, and 1477 mm respectively, with a wheelbase of 2850 mm. The front suspension of the Lincoln MKZ uses a MacPherson independent suspension, while the rear suspension uses a multi-link independent suspension.

What are the reasons for the X-Trail's air conditioning not cooling?

The reasons for the X-Trail's air conditioning not cooling are as follows: 1. Refrigerant leakage: Leakage of refrigerant in the air conditioning system leads to insufficient refrigerant, causing the air conditioning to fail to cool. You can check components such as the pipelines, air conditioning pump, condenser, and evaporator in the air conditioning system for any damage that may cause refrigerant leakage. Another inspection method is to add fluorescent dye along with the refrigerant. After using the vehicle for a week, inspect the air conditioning system with a dedicated UV lamp. If there are any leakage points, they will glow, indicating that the component is damaged. 2. Internal damage to the air conditioning pump: This prevents the cooling effect from being activated. Generally, a damaged air conditioning pump will produce abnormal noises. Therefore, check the air conditioning pump, and if it is damaged, it needs to be replaced. 3. Dirty condenser fins in the air conditioning system: This causes the pressure and temperature in the air conditioning system to rise too high. To protect the system, the air conditioning pump stops working, resulting in no cooling. You can use a high-pressure water gun to clean the condenser fins.

What is the fuel tank capacity of the Honda Greiz in liters?

The fuel tank capacity of the Honda Greiz is 40L. This data is officially published, and owners who have purchased the Honda Greiz can also check it on the vehicle's configuration sheet. The Honda Greiz uses 92-octane fuel, with a fuel consumption of 5.4-5.6L per 100 kilometers. A full tank of fuel can cover a distance of 714-740km. During daily driving, it is necessary to always pay attention to the remaining fuel in the tank. This is usually observed through the fuel gauge inside the vehicle. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge typically has 5 to 6 segments, and it is advisable to refuel when there are about 2 segments left to avoid running out of fuel midway. During actual refueling, the amount of fuel may exceed the calibrated volume. This is because the fuel tank volume specified by the car manufacturer is measured from the bottom of the tank to the safety limit, and there is additional space from the safety limit to the tank opening. This space ensures that the fuel inside the tank can expand when the temperature rises without overflowing. If fuel is added up to the tank opening during refueling, the actual amount of fuel added may exceed the calibrated tank volume.
