The calculation formula: Power (W) = 2π × Torque (N-m) × Speed (rpm) / 60. After simplification, it becomes: Power (kW) = Torque (N-m) × Speed (rpm) / 9549. From this, the horsepower of the car is calculated. The horsepower of an engine refers to the output capacity (work done) of the engine, which is the output power. Output power is a very important parameter for measuring car performance and is used to evaluate engine performance.

How to Permanently Turn Off the Auto Start-Stop Function?

To permanently turn off the auto start-stop function, locate the auto start-stop button and press it once. Vehicles equipped with auto start-stop typically have it enabled by default. If the owner wishes to disable it, simply pressing the auto start-stop button will suffice. Flexible use of the auto start-stop feature can enhance fuel efficiency and improve driving comfort to some extent. The auto start-stop system automatically shuts off the engine when the vehicle comes to a temporary stop during driving. When it's time to move again, the system automatically restarts the engine. This system helps minimize engine idling time during traffic lights or congestion, reducing unnecessary fuel consumption. Additionally, shutting off the engine when parked effectively lowers noise and vibration, providing a better driving experience.

What is the installation method for the Jetta rear axle sleeve?

The installation method for the Jetta rear axle sleeve is: 1. Use a wrench to secure the rear axle. The brake oil pipe is connected to the rear axle, and the pipe has a fixed clip. Use a hammer to slightly bend the clip for easier screw tightening, being careful not to break the oil pipe; 2. Hammer the outer iron ring of the sleeve inward until flat, carefully observing that a small part of the iron ring protrudes from the sleeve and rear axle; 3. While hammering, be cautious not to pile up the iron ring, as it may get stuck on the rear axle and be difficult to remove. If the iron ring piles up, use an angle grinder to flatten it, then remove the sleeve. Repeat the above steps for installation. Taking the Jetta VA3 as an example, this car is a compact model under FAW, with body dimensions of 4501mm in length, 1704mm in width, and 1469mm in height, and a wheelbase of 2604mm.
