What are the clever tricks for removing oil film from car windows?

Toothpaste is a clever trick for removing oil film. Toothpaste contains abrasive particles that can provide a grinding effect. When using toothpaste to clean oil film, it is important to apply the right amount of pressure and wipe evenly to better clean the pores on the glass surface and remove the oil film. Below are some related methods for removing oil film from car windows: 1. Using dry newspaper: After washing the car, use dry newspaper dipped in water to wipe the windows. Once the water on the newspaper dries, the oil film on the glass will also be removed. 2. Using specialized oil film cleaner: Spray the cleaner evenly on the glass, then wipe with a car wash towel or sponge for excellent cleaning results.

What is the wading depth of the Range Rover Sport?

The maximum wading depth of the Range Rover Sport is 900mm. The wading depth of the Range Rover Sport is determined by the height of the vehicle's chassis, which is the ground clearance listed in the model's parameter configuration table. Generally, the greater the ground clearance, the higher the chassis, and the higher the safety factor when passing through waterlogged roads. Therefore, in terms of safe wading depth, the advantages of off-road vehicles and SUVs are obvious. However, for most compact and small cars with low chassis, the position of the vehicle's air intake should be used as a benchmark when passing through waterlogged roads. If the air intake is below the water level when the Range Rover Sport is wading, water will be sucked into the engine's cylinders. Since water cannot be compressed like air, it will cause serious damage to the engine's mechanical structure (connecting rods, pistons, crankshaft, etc.). Therefore, the wading depth should not exceed the height of the engine's air intake. The height of the engine's air intake, and thus the maximum wading depth, can also be increased by installing a snorkel. If wading is unavoidable, the following safe and correct operations should be performed: Before the vehicle enters the water, the auto start-stop function must be turned off to prevent the vehicle from automatically restarting after stalling in the water, which could cause serious damage to the engine due to water intake. Judge the underwater road conditions based on the passage of the vehicle ahead and choose a suitable entry point. Observe the path taken by other vehicles and follow their tracks at low speed, avoiding sudden acceleration or deceleration. On roads prone to waterlogging, observe warning water level markers, trees, and reference points such as the wheels and doors of other vehicles to judge the water depth before deciding whether to proceed. Understand your vehicle's safe wading depth. If the water depth exceeds half of the tire height or the engine's air intake, do not enter the water rashly; choose another route instead.

What kind of scratches can car polishing repair?

Scratches caused by car washing or sand and stones during driving can be repaired by car polishing. Below is relevant information about car polishing: 1. Market position: From the perspective of car polishing, market demand is substantial, while supply is slightly insufficient. Particularly, there are not many enterprises with core intellectual property rights and high-quality products, resulting in an overall lack of brand effect in the industry. During periods of strong demand, the industry demand is enormous, and the development prospects are undoubtedly good. 2. Polishing steps: After the car surface is sprayed, minor defects such as coarse particles, sandpaper marks, flow marks, whitening, and orange peel may appear on the paint film surface. To compensate for these defects, grinding and car polishing are usually performed after spraying to improve the mirror effect of the paint film, achieving the requirements of brightness, smoothness, and brilliance.

How to Separate Gasoline and Diesel After Mixing?

Gasoline and diesel can be separated using a thin-film evaporator. Below is an introduction to gasoline: 1. Physical and chemical properties: Gasoline is a colorless to light-yellow, easily flowing liquid at room temperature, hardly soluble in water, and flammable. Its distillation range is 30°C to 220°C, and it can explode when the air concentration reaches 74-123 grams per cubic meter. 2. Preparation method: Gasoline is produced through the fractional distillation of crude oil and the cracking of heavy fractions. During crude oil processing, units such as distillation, catalytic cracking, thermal cracking, hydrocracking, catalytic reforming, and alkylation all produce gasoline components, but with different octane numbers. For example, straight-run gasoline has a low octane number and cannot be used alone as an engine fuel. Additionally, the sulfur content varies, so gasoline components with high sulfur content require desulfurization refining. Subsequently, these gasoline components are blended, and high-octane components are added if necessary, resulting in a gasoline product that meets national standards.

What are the consequences of driving a commercial vehicle without an operating license?

Driving a vehicle without an operating license on the road will not be penalized by traffic police as long as there are no traffic violations. However, engaging in commercial activities with an unlicensed vehicle constitutes illegal operation, which should result in vehicle impoundment and fines. This falls under the jurisdiction of the Transportation Bureau, not the traffic police. Below are detailed explanations about commercial vehicles: 1. Scope: Commercial vehicles refer to those approved by the competent authority at the end of the reporting period to participate in operations. This includes vehicles in good technical condition, under repair, awaiting repair, long-term parked, and those scheduled for scrapping but not yet approved by the superior authority. It does not include non-commercial vehicles of enterprises or borrowed passenger vehicles. 2. Classification: Commercial vehicles include passenger transport vehicles, freight transport vehicles, hazardous goods transport vehicles, and automobile trains.

Why is one wheel of the car not turning?

If one wheel of the car is not turning, it is usually caused by the following reasons: 1. Pulling the handbrake tightly after washing the car: In winter, do not pull the handbrake tightly after washing the car, as this can easily cause the rear wheels to freeze, resulting in one tire turning while the other does not. 2. Not maintaining the wheel bearings: This can cause the bearing cage to deteriorate and lock the axle, leading to one tire turning while the other does not. 3. Rear wheels with drum brakes: There are two brake shoes inside. When the inner brake shoe is severely worn and not replaced in time, it can easily cause the brake shoe to lock, resulting in one wheel turning while the other does not. 4. Rear wheels with disc brakes: Check if the brake fluid circuit is blocked, causing the caliper to lock the brake disc, which results in one wheel turning while the other does not.
