What does the term 'several oils' commonly mentioned in cars mean?

What is the China VI standard equivalent to?

China VI represents the China 6 emission standard, which mainly refers to the vehicle exhaust emission standards. China began implementing the China 6 emission standard on July 1, 2019. The China 6 emission standard increases the exhaust emission requirements by 50% compared to the China 5 standard. Here is an introduction to the China 6 emission standard: 1. The China 6 emission standard is divided into China 6a and China 6b. According to national regulations, starting from July 1, 2020, all light-duty vehicles sold and registered must meet the China 6a limit requirements. From July 1, 2023, all light-duty vehicles sold and registered must comply with the China 6b limit requirements. 2. The China 6 emission standard is more in line with China's actual national conditions. The carbon monoxide content in the China 6b standard is reduced by half compared to the China 5 standard, and the carbon oxide content standard is also reduced by about half. The early implementation of the China 6 standard is also very helpful for environmental improvement.

What is the difference between a 1.5T and a 1.5L car engine?

1.5L indicates that the car is equipped with a 1.5L naturally aspirated engine, while 1.5T means the car has a 1.5L turbocharged engine. Here are the differences between 1.5L and 1.5T: 1. First, the working principles are different. 1.5T refers to an engine with a turbocharger, while 1.5L is a naturally aspirated engine. The former uses exhaust gases from the engine to drive the turbo, thereby drawing in more air, with the goal of achieving more complete combustion in the engine's cylinders. This reduces fuel consumption and increases horsepower. On the other hand, 1.5L indicates that the engine is naturally aspirated, meaning the car is equipped with a 1.5L naturally aspirated engine. The entire intake process of the engine relies on the negative pressure created when the piston moves downward to draw in air. 2. Horsepower and fuel consumption differ. A 1.5T engine can increase the original engine's horsepower by 40% or even more. Therefore, cars with a 1.5T engine have greater horsepower and higher power output, resulting in slightly higher fuel consumption. Cars with a 1.5L engine rely solely on the base horsepower of the original engine, so their fuel consumption is relatively much lower. 3. The development history is different. Naturally aspirated engines (marked with L) have a longer history of use, so they have achieved significant progress in development, offering better reliability and practicality. These are their respective advantages. 4. The prices are different. Cars with naturally aspirated (L) engines are generally cheaper, while those with turbocharged (T) engines are more expensive but more environmentally friendly.

What Items Are Typically Replaced During Routine Maintenance for Small Cars?

The first maintenance generally involves checking for any issues with the car, as well as replacing the engine oil and filter. The first maintenance must be performed within either 500 kilometers or six months of the car's use, whichever comes first. Typically, the optimal time for the first maintenance is between 4,000 and 5,000 kilometers. However, if the car has been in use for more than six months, the 4S dealership will not provide the first maintenance service. Below are the documents required for the first maintenance: 1. First, bring the maintenance manual and the vehicle's registration certificate. Remember to have the 4S dealership stamp the maintenance record each time, noting the maintenance items and date. This ensures that the next owner can easily view the vehicle's maintenance history when the car changes hands. Usually, the first maintenance is complimentary with the purchase of the car. 2. The maintenance cycle is usually clearly stated in the user manual. If the 4S dealership unilaterally requests shortening the maintenance cycle, it can generally be ignored. While a shorter maintenance cycle does no harm to the car, it is primarily a way for the 4S dealership to increase revenue. 3. However, for cars manufactured too early, such as inventory cars, the first maintenance should be appropriately advanced. This is because long-term stationary storage causes severe oxidation of the engine oil. When the engine is restarted, dry or semi-dry friction occurs between the cylinders and pistons, accelerating component wear and significantly increasing startup resistance.

The Difference Between Keyless Start and Keyless Entry

They operate on different principles. The keyless entry system is designed for entry purposes, controlling the doors; whereas keyless start can only start the vehicle without granting access to the system, controlling the engine. Below are introductions to keyless start and keyless entry: 1. The automotive keyless entry system utilizes the world's most advanced RFID radio frequency technology and vehicle identity coding recognition system. It pioneers the development of compact, low-power RF antenna solutions and successfully integrates remote control systems with keyless systems while maintaining traditional vehicle circuit protection. This achieves a true dual RF system with dual anti-theft protection, providing maximum convenience and security for car owners. 3. The keyless start system allows starting the vehicle without physically turning a key. Simply keep the key in your bag or pocket, then press a button inside the vehicle or turn the ignition knob to start the engine. This offers greater convenience while significantly enhancing the sense of luxury and technological sophistication.

What type of engine oil is used for the Verna car?

Verna cars use 5W20 engine oil. Here is an introduction about automotive engine oil: 1. Function: Engine oil serves to lubricate and reduce friction in the engine, assist in cooling, provide sealing to prevent leaks, protect against rust and corrosion, and act as a shock absorber. It is often referred to as the "blood" of a car. 2. Composition: Engine oil consists of base oil and additives. The base oil is the main component of the lubricant, determining its fundamental properties, while additives compensate for and improve any deficiencies in the base oil's performance, imparting new characteristics. Additives are an essential part of the lubricant.

What does coolant mean in a car?

In a car, coolant refers to antifreeze (coolant), which is marked on the antifreeze reservoir, and the indicator light on the dashboard will also display it. The functions of antifreeze include the following two points: 1. Protecting the engine: (1) In winter, it prevents the coolant from freezing and damaging the engine: when parking in cold winter, it prevents the coolant from freezing and cracking the radiator or freezing the engine cylinder block or head; (2) In summer, it avoids boiling over: during high summer temperatures, it effectively prevents boiling and avoids overheating. The role of car antifreeze is significant, directly affecting the car's performance and lifespan. 2. It has anti-corrosion properties and can protect all these metals: since the engine cooling system includes metals such as steel, aluminum alloy, cast iron, and copper, the cylinder block and head are generally made of cast aluminum or cast iron, and the radiator is mainly made of copper and brass. Antifreeze must be able to protect all these metals as it is in long-term contact with them. Using deionized water and appropriate additives can prevent various types of corrosion.
