What is the purpose of engine oil in a car?

Engine oil serves several functions: 1. As a lubricant: It reduces friction and wear between moving parts, such as between the cylinder liner and piston rings, or the camshaft. 2. As a coolant: It absorbs heat generated in the engine combustion chamber and piston crown, cooling the engine and preventing overheating. 3. As a sealant: It fills the gaps between piston rings and cylinder liners to prevent pressure leakage. 4. As a cleaner: It prevents pollutants and oxide impurities produced during combustion from adhering to the engine interior, maintaining cleanliness. 5. As an anti-rust agent: It neutralizes acidic substances generated by combustion gases, protecting the engine from rust and corrosion. Engine oil, also known as engine lubricant, is often referred to as the lifeblood of a car. It consists of base oil and additives. The base oil is the main component of the lubricant, determining its basic properties, while additives compensate for and improve the shortcomings of the base oil, providing certain new characteristics, making them an essential part of the lubricant.

Are there i and o in license plates?

License plates do not contain the letters i and o. The license plates used by vehicle owners distinguish provinces and cities through a combination of Chinese characters and letters, followed by a small dot separating the subsequent numbers. The following five digits can form the license plate through a combination of letters and numbers. License plate naming rules: 1. The first character of the license plate is a Chinese character, representing the provincial-level administrative region where the vehicle is registered; 2. The second character of the license plate is an English letter, representing the prefecture-level administrative region where the vehicle is registered; 3. The letter A is the code for the capital city, provincial capital, or central urban area of a municipality directly under the central government. When assigning English letter codes to prefecture-level administrative regions, the letters i and o are skipped; 4. There are three rules for license plate serial number encoding: each digit of the serial number uses Arabic numerals, each digit of the serial number can use English letters individually, but the letters O and I among the 26 English letters cannot be used. The serial number allows for the presence of two English letters, but the letters O and I among the 26 English letters cannot be used.

What Causes Noise from Newly Replaced Brake Pads?

Reasons for noise from newly replaced brake pads: 1. Some brake pads contain metal wires or other hard material particles that are relatively large. When the brake pads wear down to these materials, they will make noise against the brake disc, which will stop once they are worn through; 2. Check if there is any foreign object caught between the brake disc and the pad. If the sound is muffled, it is mostly an issue with the brake caliper; 3. The brake pads were not installed with a shim: Generally, brake pads are wrapped with a shim to prevent direct contact between the brake caliper and the brake pad during operation. Without the shim, direct contact can cause collision noises, which is one of the factors leading to noise from newly replaced brake pads; 4. Poor contact between the brake pad and disc: The wear between the brake disc and pad is not uniform, causing the brake disc to become uneven and develop grooves. When new brake pads are installed, their smooth and flat surface may not make full contact with the slightly grooved brake disc, resulting in poor contact. This reduces the contact area between the two, leading to decreased braking performance and noise.

What Are the Types of Brakes?

There are five types of brakes: disc brakes, drum brakes, band brakes, expanding brakes, and V-brakes. Below is a detailed introduction to each type: Disc brakes: These use hydraulic transmission, offer significant braking resistance, and provide excellent braking performance. They are commonly used in high-end vehicles and are becoming increasingly popular. Drum brakes: These employ mechanical transmission, have a smaller braking resistance arm compared to disc brakes, are cost-effective, and deliver good braking performance. Band brakes: These also use mechanical transmission with a smaller braking resistance arm than disc brakes. They were widely used in early electric vehicles and are characterized by a sharp screeching sound during braking. Expanding brakes: These provide effective and high-safety braking but are limited by wheel constraints, making modifications difficult. Due to structural differences, electric-assist vehicle rear wheels can only be fitted with expanding or band brakes. Drum brake pads are wider, offering greater friction torque and longer lifespan with less wear, but they require more operational torque. Expanding brakes are mostly manual, with long cables that have a shorter lifespan and inferior performance compared to drum brakes. V-brakes: A very common braking device on bicycles, they generate friction by clamping the wheel rim with two brake pads to achieve braking. Named for their 'V' shape, V-brakes are widely used in various bicycles and electric bikes. They are low-cost and easy to maintain but can be slippery on rainy, muddy, or water-covered roads. Braking precautions include: Avoid frequent braking on long downhill sections, as friction between brake pads and discs (or drums) generates heat. Excessive braking can cause overheating of the discs (or drums) and abnormal hardening (carbonization) of the brake pads, drastically reducing braking efficiency and potentially leading to accidents. On such roads, use low gear and minimal throttle, relying on the engine's low RPM to control speed. Avoid frequent use of emergency braking, which is a last-resort measure. Emergency braking significantly damages vehicle components, especially transmission and braking parts. It is said that one emergency brake can wear out braking components 30 to 50 times more than normal braking and cause substantial damage to other parts like the transmission. At higher speeds, braking can be done without pressing the clutch pedal while releasing the throttle, using the engine's drag to assist in slowing down. When speed decreases, promptly press the clutch pedal to prevent engine stalling due to RPM drops, which can harm the engine. Regularly check brake fluid levels, quality, and brake pad thickness. Immediately refill or replace if any abnormalities are detected.

Why is the air conditioner making a squeaking noise?

Air conditioner squeaking noise reasons are: 1. Compressor belt noise, which may be caused by damage to the compressor belt tensioner or compressor failure. This noise usually comes from the engine compartment; 2. Blower motor noise; 3. Excessive dust accumulation in the air vent swing mechanism due to long-term lack of cleaning, causing noise during operation; 4. Malfunction of the temperature control switch or air circulation motor inside the control panel. Automotive air conditioning refers to the air conditioning device installed in vehicles, which can cool, heat, ventilate and purify the air in the cabin, providing a comfortable environment for passengers, reducing driver fatigue and improving driving safety.
