What's the difference between red and green car antifreeze?

The difference between red and green car antifreeze lies in their chemical compositions. The main components of antifreeze are ethylene glycol, propylene glycol, diethylene glycol, silicates, etc. The mixed solution formed by blending the mother liquor with pure soft water in different proportions is called antifreeze. Typically, ethylene glycol is green, while propylene glycol is red with a hint of orange. Antifreeze itself is a transparent liquid, but the addition of different types of additives results in various colors, which are used for differentiation to prevent incorrect or mixed usage. Ethylene glycol antifreeze is more commonly used in the market. Different colored antifreeze should not be mixed, as their chemical compositions vary. Mixing them can easily lead to chemical reactions, causing sediment or bubbles to form in the antifreeze reservoir, which can damage the cooling system and rubber seals. In severe cases, impurities may form, clogging the cooling system pipes. Once the cooling system pipes are clogged, antifreeze cannot function properly, preventing the engine from dissipating heat in time, leading to wear and affecting the engine's lifespan. Antifreeze is a coolant with special additives, also known as coolant. As the name suggests, it has two main functions: preventing freezing and cooling. Antifreeze ensures that the car engine does not freeze in cold weather and also cools and prevents overheating during high-temperature engine operation in summer.

Where to Find the Vehicle Equipment Number?

The methods to check the vehicle equipment number are: 1. There is a barcode on the outside of the vehicle equipment packaging box, which displays the equipment number; 2. The barcode on the vehicle equipment shell shows the equipment IMEI number; 3. The owner can directly contact customer service personnel, who can assist in querying the equipment number. The equipment number is also known as the chassis number. The chassis number (Vehicle Identification Number), abbreviated as VIN, is called the vehicle identification code in Chinese. It is a 17-digit alphanumeric code. Just as every person has an ID card, because of its unique identification for the vehicle, it is referred to as the vehicle's ID card.

Can you drive on the highway during the B2 probationary period?

During the B2 probationary period, you are not allowed to drive on the highway. Here are some precautions for new drivers on the highway: 1. Pay attention to traffic rules and display a probationary sign: Please follow traffic rules and display a probationary sign at the rear of your vehicle so that other drivers can be alert. 2. Have an experienced driver accompany you: If it's your first time driving on the highway, it's best to have a driver with more than three years of driving experience or someone with extensive highway experience accompany you. 3. Inspect your vehicle before entering the highway: Before setting off, you must inspect your vehicle, especially the tires, brakes, spare tire, water, oil, etc. 4. Observe speed limits: Every highway has a minimum speed limit, so make sure not to drive below the minimum speed limit on the highway.

What are the pros and cons of naturally aspirated and turbocharged cars?

Naturally aspirated and turbocharged cars have the following advantages and disadvantages: 1. Advantages of turbocharging: high combustion efficiency (often combined with direct injection, stratified injection and other technologies), small displacement with high power, and good high-speed fuel economy. 2. Disadvantages of turbocharging: turbo lag, which means the rhythm cannot keep up with the engine. This is common in large turbochargers and affects handling. 3. Advantages of naturally aspirated engines: fast throttle response and linear acceleration. 4. Disadvantages of naturally aspirated engines: lower efficiency at high speeds compared to turbocharged engines, lower power per liter, and the maximum torque range occurs at higher RPMs than turbocharged engines.

How to Check Tire Pressure?

Currently, many vehicles are equipped with tire pressure sensors that monitor the internal pressure of the tires. The tire pressure is displayed directly on the dashboard, or it can be measured using a tire pressure gauge. The specific introduction to tire pressure monitoring is as follows: 1. Direct Tire Pressure Monitoring: This system uses pressure sensors installed in each tire to directly measure the tire pressure. The pressure information is transmitted from inside the tire to a central receiver module via a wireless transmitter, and then the tire pressure data for each tire is displayed. When the tire pressure is too low or there is a leak, the system will automatically issue an alarm. 2. Indirect Tire Pressure Monitoring: The working principle is that when the pressure of a tire decreases, the weight of the vehicle will cause the rolling radius of that wheel to become smaller, resulting in a faster rotation speed compared to the other wheels. By comparing the speed difference between the tires, the system can monitor the tire pressure. The indirect tire pressure alert system actually relies on calculating the rolling radius of the tires to monitor the pressure.

What Does Keyless Start Mean?

Keyless entry system refers to an intelligent system that utilizes advanced RFID (Radio Frequency Identification) technology and identity code recognition system. Below are the specific details about keyless start: 1. Keyless Start System: Keyless start means using a smart key. With this key near the car door (approximately 2 meters), you don't need to open the door manually; just pull the handle to open it. Once inside the car, there's no need to insert the key into the ignition; simply turn the key switch to start the vehicle. After leaving the vehicle, there's no need to lock it manually; just move away from the door (about 2 meters), and the doors will automatically lock. 2. The Difference Between Keyless Start and Keyless Entry: Keyless start emphasizes the system for starting or turning off the engine inside the car. Generally, there is a one-touch start button (or knob) inside the car; just press it lightly to start the vehicle's engine, and the same applies to turning it off. Keyless entry emphasizes the action of opening the car door without pressing the unlock button on the key. With the smart key on your person, the door can be unlocked through sensing.
