What is the difference between Michelin Energy XM2 and XM2+?

What does DVVT mean?

Dvvt is the variable valve timing technology for engine intake and exhaust valves. Detailed information is introduced as follows: 1. When the engine is working, it outputs power by mixing the air and fuel vapor entering the engine and burning them in the combustion chamber. 2. Air enters the combustion chamber through the intake valve and is discharged through the exhaust valve after combustion. In this way, during the entire working process of the engine, the intake and exhaust volumes are fixed. 3. The opening and closing of the intake valve are driven by the camshaft, that is, the valve timing depends on the angle of the camshaft.

Where is the horn located on the BMW 3 Series?

This model has two horns in the center of the dashboard, one on each side near the exterior rearview mirrors on the front doors, one in the middle of each front door, one in the middle of each rear door, one behind each rear seat, and one tweeter in front of each rear door. There are also two subwoofers under the front seats. Speaker Introduction: Speakers, commonly known as horns, are an indispensable component of an audio system. The number of speakers determines the distribution of sound emission points. The more speakers the BMW 3 Series has, the better the surround sound effect and the stronger the stereo sensation. The number of speakers in the BMW 3 Series can also reflect the level of luxury of the vehicle. Active Noise Cancellation System: The active noise cancellation system in a car can minimize interior noise. If the BMW 3 Series is equipped with this system, the roof will have several microphones to continuously collect noise signals and engine information. When noise is detected, the car's amplifier will instruct the speakers to emit sound waves opposite to the interior noise, thereby canceling out the noise waves. This provides BMW 3 Series owners and passengers with a quieter and more comfortable experience.

Why does the car still shake after replacing spark plugs?

The reason the engine shakes after replacing spark plugs is that the spark plugs are not tightened properly. Therefore, the force used when replacing spark plugs should be based on the required torque for the specific spark plugs being used, as spark plugs of different sizes require different amounts of force. Steps for replacing spark plugs: Open the hood, lift the plastic cover of the engine, remove the high-voltage distributor wires, and mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for any external debris like leaves or dust and ensure everything is cleaned thoroughly. Place the new spark plugs into the spark plug holes, hand-tighten them a few turns, and then use the socket to tighten them further. Reinstall the high-voltage distributor wires in the firing order and secure the cover. Spark plug replacement intervals: Under normal maintenance conditions, spark plugs should be replaced every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it's recommended to follow the owner's manual. The following standards can be used as a reference for maintenance and replacement: Platinum spark plugs should be replaced at 40,000 kilometers, standard nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers.
