Prefix: Includes product series code, generation symbol, and regional or enterprise code. Manufacturers can choose the corresponding letters as needed, but they must be approved and filed by the industry standard regulatory body. 2. Middle section: Consists of the cylinder count symbol, cylinder arrangement symbol, stroke symbol, and cylinder diameter symbol. 3. Suffix: Composed of structural feature symbols and usage feature symbols. 4. Tail: Distinguishing symbol. When differentiation is needed due to improvements or other reasons within the same product series, the manufacturer selects appropriate symbols. The suffix and tail can be separated by a hyphen (-).

What are the advantages of pure electric vehicles?

Pure electric vehicles are powered by charging the vehicle's battery from an external power source, which then drives the electric motor. Pure electric vehicles offer the following advantages: 1. Environmental Protection: Electric vehicles use power battery packs and electric motors for propulsion, producing no exhaust gases or tailpipe emissions during operation, which is highly beneficial for environmental protection and air cleanliness. 2. Low Noise: Electric vehicles do not generate noise like conventional vehicles, and the noise they produce is very minimal. 3. Economical: The operating cost of electric vehicles is low, approximately one-fifth that of gasoline-powered vehicles. They also have high energy conversion efficiency and can recover energy during braking and downhill driving, improving energy utilization efficiency. Charging during nighttime using the grid's low-cost "off-peak electricity" helps balance peak and off-peak grid loads. 4. Easy Maintenance: Electric vehicles are driven by motors and batteries, eliminating the need for the complex maintenance tasks associated with traditional engines, such as changing engine oil, filters, belts, etc. Electric vehicles only require regular inspections of components like the motor and battery. 5. Policy Advantages: They enjoy higher lottery success rates for license plates, substantial subsidies, and exemption from purchase taxes, making their policy advantages quite significant.

What are the main components of antifreeze?

The main components of antifreeze are 50% purified water, 40% methanol, and 10% other substances. Classification of antifreeze: Antifreeze is generally divided into three types: ethanol-water type, glycerol-water type, and ethylene glycol-water type. The basic indicators of antifreeze are freezing point and boiling point. In the market, antifreeze comes in several specifications with freezing points of -15°C, -25°C, -30°C, -40°C, etc. It is generally advisable to choose one that is at least 10°C lower than the lowest temperature in your region. Antifreeze replacement cycle: For vehicles that run for long periods, such as taxis, high-quality antifreeze should generally be replaced once a year. For vehicles with shorter running times, replacement can be done every two years or every 30,000 kilometers. To prevent excessive foam formation, which can reduce the heat exchange efficiency between the antifreeze and engine components, ensure the product is within its validity period when adding it. Long-lasting antifreeze can have a validity period of up to three years. If suspended matter, sediment, or signs of deterioration or discoloration are found in the antifreeze, it should be replaced promptly, and the system should be cleaned.

Can the remaining half of the coolant still be used?

Coolant remaining half can still be used. Coolant is a type of cooling liquid containing special additives, mainly used in liquid-cooled engine cooling systems. It has excellent properties such as preventing freezing in winter, boiling in summer, and preventing scale and corrosion all year round. Types of coolant: Coolant is generally divided into three types: ethanol-water type, glycerol-water type, and ethylene glycol-water type. Methods for selecting coolant: The basic indicators of coolant are freezing point and boiling point. On the market, coolants come in several specifications with freezing points of -15℃, -25℃, -30℃, -40℃, etc. It is generally advisable to choose one that is at least 10℃ lower than the lowest temperature in your region. Functions of coolant: Coolant is non-corrosive. It is a type of cooling liquid containing special additives, mainly used in liquid-cooled engine cooling systems. Coolant has excellent properties such as preventing freezing in winter, boiling in summer, and preventing scale and corrosion all year round. Composition of coolant: The main components of coolant are: fifty percent pure water, forty percent methanol, and ten percent other substances.
