What Should Be Noted During the Break-in Period of a New Car?

During the break-in period of a new car, it is important to avoid excessively high RPM, control the throttle reasonably, and warm up the car before setting off. Below are detailed explanations of these precautions: Avoid excessively high RPM: Compared to the maximum RPM of over 6000 for most civilian vehicles, it is advisable to keep the RPM below 4000 during the break-in period. Control the throttle reasonably: Reasonable control means avoiding sudden acceleration and deceleration. Being gentle with the throttle can reduce the working pressure on the engine. Warm up the car before setting off: Warm up the car for 1 minute before driving, and avoid aggressive throttle usage for the first few minutes after setting off. This practice is beneficial not only during the break-in period but also for the long-term health of the car.

Is it necessary to wear a seat belt in the passenger seat?

The passenger must wear a seat belt. Below is relevant information about wearing a seat belt in the passenger seat: Penalties for not wearing a seat belt in the passenger seat: When a motor vehicle is in motion, the passenger must wear a seat belt. Surveillance cameras at intersections will capture violations, and passengers found not wearing seat belts will be fined without penalty points. Driving without a seat belt incurs both a fine and penalty points. Importance of wearing a seat belt in the passenger seat: In the event of a collision or rollover, seat belts play a crucial role in protecting passengers' lives by securing them in their seats. Even with airbags, protection is only effective for those wearing seat belts. Passengers not wearing seat belts may be violently thrown around due to inertia during a collision, and airbags can even cause severe injuries to them. This is because airbags deploy at extremely high speeds and with great force, potentially ejecting unbelted passengers in any direction.

What Causes Engine Abnormal Noise During Acceleration?

Acceleration engine abnormal noise is caused by excessive valve clearance, loose interior door panels, or lack of engine maintenance. Below are detailed explanations for these causes: Excessive Valve Clearance: The opening and closing degree of valves affects the vehicle's power output. However, valves will wear after prolonged use. When the valve clearance becomes too large, abnormal noise occurs during acceleration. Loose Interior Door Panels: If the noise is heard inside the cabin during acceleration, it is likely caused by loose door panels. Vehicles that have had their center console removed previously are more prone to such abnormal noises. Lack of Engine Maintenance: If the engine oil is excessively dirty, it will affect the lubrication performance of the engine, making the vehicle more susceptible to abnormal noises.

What is the Difference Between Dual-Clutch and Tiptronic Transmissions?

The differences between dual-clutch and tiptronic transmissions lie in fuel economy, power performance, and cost. Below are detailed explanations of these differences: Fuel Economy: The dual-clutch transmission, which essentially consists of two automatic clutches, is more fuel-efficient. Power Performance: The tiptronic transmission, developed from traditional automatic transmissions, has a relatively slower response speed overall. To protect the engine, its power performance is somewhat weaker. Cost: Tiptronic transmissions are generally used in some mid-to-high-end vehicles, offering relatively quick gear shifts. Dual-clutch transmissions are typically found in high-end models and sports cars, with very expensive components. In terms of cost, tiptronic transmissions are more affordable.
