What Causes the Rattling Noise in the Car Trunk?

What is the actual lifespan of Nissan's CVT transmission?

Nissan's CVT transmission can last between 400,000 to 500,000 kilometers, but minor issues typically start appearing after 100,000 kilometers. Here's more information about CVT transmissions: 1. CVT refers to a type of automotive transmission, also known as a continuously variable transmission. It mainly consists of two conical pulleys and a steel belt or chain. The two conical pulleys can be tightened or loosened via electronically controlled hydraulic pressure, changing the diameter of the steel belt wrapped around them to achieve different gear ratios. During startup, the driving pulley has the smallest diameter while the driven pulley has the largest diameter; during high-speed driving, the driving pulley's diameter increases while the driven pulley's diameter decreases. The entire diameter-changing process is controlled by a computer, enabling seamless and stepless adjustment. 2. CVT transmissions provide excellent fuel efficiency for vehicles, ensuring smooth driving experiences while effectively reducing emissions.

What car is the 'Song' license plate?

The 'Song' license plate refers to a model under the BYD automotive brand called the Song. The BYD Song can be considered the dual-mode version of the BYD S3, positioned as a new energy compact SUV. It features an X-shaped front grille, giving it a sporty appearance. The side profile of the car adopts hidden A/B/C pillar designs, creating a floating roof visual effect. Additional Information: 1. The Song was BYD's flagship model in 2015, dubbed the 'SUV Year,' and was one of the key members of the '542 Strategy.' The model made its debut at the Shanghai Auto Show. Prior to this, BYD had already launched the Tang, but its higher positioning led to a relatively higher price. Therefore, for many consumers, the slightly more affordable BYD Song became a highly anticipated alternative. 2. The front of the BYD Song features an X-shaped design, giving it high recognition. The hexagonal mesh grille, paired with sharp headlights on both sides, gives it a distinctive look. At the rear, the taillights follow the design language of the headlights, with equally sharp lines. The car measures 4565mm in length, 1830mm in width, and 1703mm in height, with a wheelbase of 2660mm. According to reports, the BYD Song's dimensions are 4565/1830/1703mm, with a 2660mm wheelbase, officially positioning it as a 'mid-size SUV.'

How to Distinguish Between Good and Bad Spark Plugs?

Methods to determine the quality of spark plugs: 1. Spark Test: Remove the spark plug and test it on the cylinder block with a high-voltage wire. If there is no spark or the spark is weak, it indicates that the spark plug is leaking electricity or not working. 2. Color Observation: Remove the spark plug. If the surface appears reddish-brown or rust-colored, it indicates the spark plug is normal; if it is oily, it indicates a gap misalignment, excessive fuel supply, a short circuit in the high-voltage wire, or non-operation; if the spark plug is severely eroded, with phenomena such as blistering at the top, black streaks, cracks, or electrode melting, it means the spark plug is damaged and must be replaced immediately. Effects of a Bad Spark Plug: If the spark plug is damaged, it can directly cause issues such as leakage in the vehicle's ignition system, increased fuel consumption, and reduced power. The main problem is difficulty in ignition, affecting the normal use of the vehicle. Severe erosion of the spark plug, blistering at the top, damage, or melting and erosion of the electrode all indicate that the spark plug is ruined and should be replaced.

What do 98V and 98H on tires mean?

The meanings of 98V and 98H on tires are as follows: 1. The 98 in 98V represents the load index of the tire; V indicates the speed rating, meaning the maximum speed the tire can withstand is 240 km/h. 2. The 98 in 98H also represents the load index of the tire, and H indicates the maximum speed the tire can withstand is 210 km/h. Below is more information about car tires: 1. Tires are circular elastic rubber products installed on various vehicles or machinery to roll on the ground. Mounted on metal rims, they support the vehicle body, cushion external impacts, and ensure contact with the road surface to maintain driving performance. 2. The speed rating indicates the maximum speed at which the tire can carry a specified load under specified conditions. Different tires have speed ratings marked with English letters on their sidewalls, such as Q for 160 km/h, R for 170 km/h, S for 180 km/h, and so on.

What causes abnormal noise when braking in reverse but normal when moving forward?

Abnormal noise when braking in reverse but normal operation when moving forward may be due to the following reasons: 1. The brake pads have metal hard spots, as there are some small metal particles inside the brake pads, which can cause abnormal noise when lightly braking. In this case, you can stomp on the brakes a few times or remove the brake pads for re-grinding, or replace them with better quality brake pads. 2. The brake pads are severely worn and begin to sound an alarm. Brake pads usually have warning indicators. When the brake pads wear to their limit, the warning indicators will rub against the brake disc, producing sharp metal friction sounds. At this point, it is essential to replace the brake pads promptly to avoid scratching the brake disc and brake failure.

What does a circle with an A and OFF mean on a car?

The A with a circle and OFF on a car stands for AUTO, which means automatic; OFF means off, so together it means the vehicle's auto start-stop function is turned off. Below is some relevant information about the auto start-stop function: 1. The use of the auto start-stop system has certain conditions. It cannot be used when the battery is low, the temperature is too high or too low, the wheels are turning when stopping, the slope is too steep, or the seat belt is not fastened. 2. After turning on the auto start-stop function, simply press the brake pedal while driving. The engine will automatically shut off after the vehicle comes to a complete stop for about two seconds. Keeping the brake pedal pressed will keep the engine in the off state.
