What to Do with China V After China VI?

After the implementation of the China VI standard, China V vehicles will not affect normal road use. Vehicles already sold will follow the emission standards at the time of sale, so China V vehicles will still undergo annual inspections using the China V standard. The China VI standard is an upgrade to the China V standard and will become one of the strictest standards globally. Relevant information about China V and China VI is as follows: 1. Compared to the China V standard, China VI will strictly control pollutant emission limits. 2. Excluding the influence of driving conditions and testing, carbon monoxide emissions from gasoline vehicles will be reduced by 50%, total hydrocarbon and non-methane hydrocarbon emission limits will decrease by 50%, and nitrogen oxide emission limits will be tightened by 42%. 3. The new standard is only to constrain automakers, ensuring that sold vehicles meet the China VI standard requirements. For vehicles already purchased under the China V standard, they will still follow the emission status at the time of purchase.

Should You Shift Gears or Release the Handbrake First When Starting the Car?

You should shift gears first and then release the handbrake. Here are the reasons: 1. The primary reason for this is safety. After shifting into gear, the power transmission path of the transmission is connected. When you first shift into gear, the transmission is in first gear, which provides the highest torque. If the brake is not properly engaged, the car might suddenly lurch forward. 2. If you shift into gear without releasing the handbrake, all the power output from the engine will be absorbed by the torque converter, causing its temperature to rise rapidly. Prolonged operation under these conditions can damage the torque converter. 3. For dual-clutch transmissions, after shifting into gear, the clutch friction plates will be in a semi-engaged state. Prolonged semi-engagement can lead to burning out the friction plates, so it's necessary to start moving as soon as possible.

What is the bulge in the middle of the rear seat of a sedan?

The bulge in the middle of the rear seat of a sedan is designed to maintain the flatness of the chassis. Since the underside of the car's chassis accommodates the exhaust pipe or drive shaft, rear-wheel-drive vehicles typically require a drive shaft to transmit power from the engine to the rear wheels, necessitating this structural bulge. Below are specific details on the related content: 1. For rear-wheel-drive vehicles, the middle section needs to house the drive shaft. The front-mounted engine transmits power to the rear wheels via the drive shaft. If the drive shaft is too low, it may lead to scraping the ground, affecting the car's ground clearance. Raising the vehicle height would compromise the car's center of gravity. Therefore, a localized raised floor is designed to protect the drive shaft while enhancing the car's stability, ground clearance, and handling. 2. If the car has a low chassis design and is front-wheel-drive, the middle bulge may serve as space for the exhaust pipe layout. 3. Even if the car is front-wheel-drive, the chassis might be built on a rear-wheel-drive platform or shared with higher-end models (rear-wheel-drive platform), resulting in the middle bulge in the rear seat.

How Long Does It Take for a Beginner to Become Proficient at Driving?

Driving proficiency can generally be measured by the distance driven. The first 3,000 kilometers represent a pure beginner phase, during which driving in crowded or high-traffic areas can be quite challenging. Between 3,000 to 10,000 kilometers, driving skills improve significantly. After 50,000 kilometers, one typically reaches a highly proficient level, essentially joining the ranks of experienced drivers. Below are some important considerations for beginner drivers: 1. Display a Novice Driver Sign: Signs like "New Driver, Please Be Patient" or "Slow-moving Novice Driver" may incur penalties if spotted by traffic police. Instead, use the officially designated "Novice Driver" sign issued by traffic authorities. 2. Perform Pre-Drive Vehicle Maintenance: Beginners must adhere to regular vehicle maintenance schedules before hitting the road. Always inspect the vehicle's condition before driving, such as walking around the car to check for oil leaks and ensuring proper tire pressure in all four wheels. While driving, be alert to any unusual conditions, such as vibrations or strange noises. 3. Stick to Familiar Routes: Beginner drivers should stick to roads they know well and avoid unfamiliar routes to prevent getting lost or taking unnecessary detours. While driving, pay attention to common landmarks to enhance memory of the route.

What Causes Car Wipers to Not Clean Properly?

There are several reasons why car wipers may not clean properly: 1. Oil film on the windshield, causing the wipers to not clean effectively: The simplest way to remove oil film is to use an oil film cleaner, but it's important to apply it evenly. 2. Foreign objects between the wiper blade and the windshield: If you hear a sharp friction sound when using the wipers, check and remove any debris from the wiper blade or underneath it to ensure nothing is interfering with the contact between the blade and the windshield. 3. Damaged wiper blades: Car parts have a lifespan, and wipers are no exception. If the wipers make metallic noises and fail to adhere properly to the windshield, the wiper may be deformed or its internal spring may have aged. In such cases, it's best to visit a 4S shop for replacement with genuine parts. 4. Aging wipers: Wipers are primarily made of CR chloroprene rubber, natural rubber, and EPDM ethylene propylene diene monomer rubber. Rubber has a limited lifespan, and prolonged exposure to wind, sun, and rain inevitably leads to hardening and aging.

What are the reasons for difficult cold starts of an engine?

Engine cold start difficulties are caused by the following reasons: 1. Poor fuel quality: Inferior fuel has poor volatility, especially in winter when it is difficult to atomize, resulting in insufficient mixing of fuel and air in the cylinder, leading to difficult starts or even failure to start. 2. Excessive carbon deposits on valves and intake manifolds causing cold start difficulties: Carbon deposits can absorb an appropriate amount of fuel, leading to ECU judgment errors. For example, if the computer controls the injection of 100 parts of fuel-air mixture, but only 90 parts actually enter the cylinder (10 parts absorbed by carbon deposits), even if the remaining 90 parts fully combust, the required power output cannot be achieved, inevitably causing shaking. 3. Excessive carbon deposits: Carbon deposits negatively affect the normal operation of the engine. For instance, excessive carbon deposits in the combustion chamber increase the compression ratio, creating multiple hot spots that cause pre-ignition and detonation, shortening the engine's lifespan. Carbon deposits on the valve and seat surfaces can prevent the valve from sealing properly, leading to air leakage, difficult engine starts, reduced power, and other adverse phenomena such as valve erosion.
