What kind of oil is used for oil mops for car cleaning?

Oil mops for car cleaning use industrial liquid paraffin. Paraffin: Paraffin is a hydrocarbon mixture extracted from certain distillates of petroleum, shale oil, or other asphalt mineral oils. Its main component is solid alkanes, which are odorless and tasteless, appearing as white or light yellow semi-transparent solids. Paraffin is non-crystalline but has a distinct crystalline structure. There is also synthetic paraffin. Paraffin classification: Depending on the degree of refining, paraffin can be divided into three types: fully refined paraffin, semi-refined paraffin, and crude paraffin. Each type is further classified by melting point, generally in increments of 2 degrees Celsius, into different grades such as 52, 54, 56, 58, etc. Crude paraffin has a higher oil content and is mainly used in the manufacture of matches, fiberboard, canvas, etc.

Is all gasoline in China ethanol-blended?

No. Whether gasoline is ethanol-blended depends on the letter before the number. Ethanol-blended gasoline is marked with the letter E before the octane rating, such as E92 gasoline, which is ethanol-blended. Pure gasoline is directly labeled with numbers like 95 gasoline. Ethanol-blended gasoline: The gasoline commonly referred to is unleaded gasoline (containing trace amounts of lead), while ethanol-blended gasoline refers to the addition of a certain proportion of fuel ethanol (commonly known as alcohol) to regular unleaded gasoline. In China, this proportion is 10%. In simple terms, it means adding 10% biofuel ethanol to gasoline. Precautions for using ethanol-blended gasoline: For cars that have been driven more than 30,000 kilometers, if the fuel tank and fuel lines are not cleaned before using ethanol-blended gasoline for the first time, it may easily cause fuel line blockage and engine stalling. Even after cleaning, a small amount of impurities may still enter the fuel tank. After using the first tank of ethanol-blended gasoline, the car should be inspected and cleaned. However, for new cars with a mileage of less than 30,000 kilometers, the fuel tank and fuel lines do not need to be cleaned before adding ethanol-blended gasoline.

What phenomena will occur if a wet air filter continues to be used?

Continuing to use a wet air filter can result in the engine failing to start. The engine may experience poor acceleration, sluggishness, and insufficient fuel supply. If the moisture from the wet air filter enters the cylinders severely, it can lead to engine seizure, causing engine damage and ultimately ruining the engine. Detailed introduction to car air filters: An air filter is a type of filter, also known as an air filter cartridge, air cleaner, or air element. It is primarily used for air filtration in engineering vehicles, automobiles, agricultural vehicles, laboratories, sterile operating rooms, and various precision operating rooms. Impact of an unfiltered car air filter: When the engine is running, it needs to draw in a large amount of air. If the air is not filtered, the dust suspended in the air can be sucked into the cylinders, accelerating the wear of the piston group and cylinders. Larger particles entering between the piston and cylinder can cause severe cylinder scoring, which is particularly serious in dry and sandy working environments. Function of the air filter: The air filter is installed in front of the carburetor or intake pipe to filter out dust and sand particles from the air, ensuring that sufficient and clean air enters the cylinders.

Does a dented exhaust pipe affect the vehicle?

If it is just a slight dent and does not cause any exhaust leakage, then a minor dent will not have any impact. The main thing is to check whether there is any leakage that causes the exhaust pipe to become louder, or whether it is rubbing against other parts and causing abnormal noises. Material: The material of the exhaust pipe is mostly stainless steel. For a car, the exhaust pipe can help reduce vibration, lower noise, and extend the service life of the vehicle's exhaust system. This is because the exhaust gas requires significant pressure to exit, which can generate considerable noise. Therefore, one of the functions of the exhaust pipe is noise reduction. Working Principle: By diverting the automobile exhaust, these diversions gradually reduce the flow speed of the gas. After a certain cycle, the exhaust gas is finally released from the car's exhaust pipe, thereby lowering the noise. Hence, if the exhaust pipe leaks, it can affect driving safety. Function: For the car body, the exhaust pipe plays a role in vibration reduction, noise suppression, and extending the lifespan of the exhaust muffler system. The main material of the exhaust pipe is stainless steel. For most cars, since the exhaust gas exits the engine under high pressure, the noise it produces can be quite overwhelming. The primary noise-reducing function is performed by the car's exhaust pipe, which contains an internal muffler that significantly reduces the vehicle's noise.

What does the yellow triangle with an exclamation mark inside the car mean?

A triangle with an exclamation mark inside indicates a malfunction in the vehicle's general performance or components and functions. Common issues include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, and engine oil pressure sensor failure. Solution: It is necessary to visit a 4S shop for inspection to identify the source of the fault. The exclamation mark is a common fault indicator in cars. Besides the triangle with an exclamation mark, there are four other forms of exclamation mark indicators: a yellow gear with an exclamation mark inside, a red circle with an exclamation mark in the middle, a yellow bracket with a horizontal line and an exclamation mark in the middle, and a yellow bulb with an exclamation mark. Below is a detailed analysis of these four scenarios: Automatic transmission fault: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a transmission malfunction or transmission lubricant below the normal range. The transmission oil should be replaced promptly. Brake system fault: A circle with an exclamation mark in the middle represents a brake system warning, mainly indicating brake system failure or low brake fluid level. Immediate inspection and repair of the brake system are required to avoid accidents. Tire pressure abnormality: A bracket with a horizontal line and an exclamation mark in the middle represents the tire pressure monitoring warning light, which illuminates when the tire pressure is too low. Check the car's tire pressure and restore it to the normal range. Lighting fault: A yellow bulb with an exclamation mark is the lighting fault indicator, indicating a malfunction in the car's lights. Solution: Visit a 4S shop for inspection and repair as soon as possible, or conduct a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting to identify the issue.
