The functions of the lubrication system include the following points: 1. Lubricate the surfaces of moving parts to reduce friction resistance and wear, thereby decreasing engine power consumption; 2. Continuously circulate oil within the lubrication system to clean friction surfaces and carry away debris and foreign particles; 3. Continuously circulate oil within the lubrication system to carry away heat generated by friction, serving a cooling function; 4. Form an oil film between moving parts to improve sealing and prevent gas or oil leakage; 5. Create an oil film on part surfaces to protect them from corrosion and rust; 6. Lubricating oil can also be used as hydraulic oil, serving a hydraulic function; 7. Form an oil film on the surfaces of moving parts to absorb impacts and reduce vibrations, providing shock absorption and cushioning effects.

The lubrication system is like the guardian angel of the engine, and I can share some real insights. Back when I first started driving, the mechanic explained in detail during maintenance that its primary role is to reduce friction between internal components—like the crankshaft and pistons. When these metal parts rub against each other, they generate heat and wear, but applying engine oil makes them glide as smoothly as ice skating. It also cools the engine; at high speeds, component temperatures soar, and the lubricating oil film carries away heat to prevent overheating and engine failure. The cleaning function shouldn’t be overlooked either—engine oil flushes metal debris and carbon deposits into the filter, preventing clogs in the pipelines. Another clever feature is sealing the combustion chamber, helping piston rings fit tightly to boost fuel efficiency and reduce leaks. Rust and corrosion prevention is also crucial, as the oil forms a protective layer to shield parts from moisture and erosion. Regular oil changes keep the car lively and extend its lifespan, whereas neglecting them could lead to engine seizure, costly repairs, or even total failure.

What is the difference between MT and CVT?

MT and CVT both refer to types of automotive transmissions, with the difference being that MT stands for manual transmission, while CVT is an automatic transmission. Below are the relevant introductions about MT and CVT: MT: MT requires manually shifting the gear lever (commonly known as the gear stick) to change the gear engagement position inside the transmission, altering the gear ratio to shift the car's speed. Most manual transmissions in passenger cars are four or five-speed gear transmissions, typically equipped with synchronizers for easier shifting and reduced noise. When operating a manual transmission, the clutch must be depressed to move the gear lever. CVT: The gear ratio in a CVT is not a series of discrete points but a continuous range of values, for example, it can vary from 3.455 to 0.85. The structure of a CVT is simpler than that of a traditional transmission, with a smaller size. It does not have the numerous gear pairs of a manual transmission nor the complex planetary gear sets of an automatic transmission. Instead, it primarily relies on the primary and secondary pulleys and a metal belt to achieve stepless variation of the gear ratio.

What is the standard tire pressure for cars?

The standard tire pressure for cars is between 2.4 and 2.5 bar. Tire pressure significantly affects vehicle performance and power. The impacts of overinflation are: 1. Reduced tire friction and adhesion, affecting braking performance; 2. Steering wheel vibration and deviation, reducing driving comfort; 3. Accelerated wear on the central tread pattern, shortening tire lifespan; 4. Increased body vibration, affecting the longevity of other components. The effects of underinflation include: 1. Increased friction coefficient with the road surface; 2. Heavier steering wheel feel and tendency to deviate; 3. Increased movement of tire components, causing abnormal heat generation due to excessive rolling.

What Does the Three-Year or 100,000-Kilometer Vehicle Warranty Cover?

The three-year or 100,000-kilometer vehicle warranty primarily covers the core components of the vehicle, which include the engine, chassis, transmission, and drivetrain. The vehicle warranty means that the manufacturer will replace faulty parts free of charge if they are confirmed to be defective due to quality issues rather than human damage, provided the replacement occurs within the warranty period or the specified mileage limit. The warranty does not apply under the following circumstances: 1. Failure to follow the manufacturer's requirements for regular maintenance at designated 4S shops or authorized service stations; 2. Unauthorized modifications to the vehicle or changes to its intended use; 3. Damage caused by improper use or traffic accidents.
